The Second Geneva Convention of 1949 concerning the Improvement of the Condition of Wounds, Sick and Victims of the Armed Forces in the Sea, is an improvement over the Hague Convention of 1907 on the same matter. The Hague Convention of 1907 concerning the protection and improvement of the fate of victims of land warfare in conditions of war at sea. Whereas in Islamic law, sea warfare was underestimated by Islamic jurists. The lack of attention shows, that at the beginning of the growth of Islam, moslems have not realized that the sea is important, and perhaps more importantly caused Islamic power does not cover the sea, but only applies on land. Therefore they depend on qiyas rules about land warfare or the customs of other nations that has been recognized.

Abstract The paper lines up with studies that discuss the impact of the Jewish War and Vespasian’s advancement on the composition of the Gospel According toMark. Its topic is to show that Mk 4,35-41 and Mk 5,1-20 form a structural unity that insinuates the idea of a Christian peace, distinguished from Roman warfare and peace. Following those scholars who read Mk 5,1-20 as an allusion to the legio X Fretensis it is argued that Mk 4,35-41 and Mk 5,1-20 are tied together in light of the Roman peace propaganda that claimed apeace by land and by sea - as did Vespasian after the civil war, when he reminded the Romans of Octavian’s victory at fretum Siculum.

Abstract Drones are new means and methods of warfare which, apparently, are similar to combat aircrafts. A big difference between the two categories is the human personnel involved. Compared with airplanes, carrying a human crew on board - this one carrying out combat operations from inside the aircraft - drones do not have inside human beings, being coordinated from the ground (or sea) - the military actions carrying out from the place where the operators are. So the question arises: what kind of rules of international humanitarian law are applicable to the use of drones in armed conflicts? Starting from the rule that legal rules apply to legal relationships between people (but not directly to objects or animals), I analyze to what extent these means and methods of warfare are subject to the rules of armed conflict on land, sea or air.

The purpose of the international humanitarian law applicable to armed conflicts at sea is the same as the International Humanitarian Law relevant to land conflicts: to reduce the destructive consequences of the armed conflict to a minimum, to protect the civilians and other non-combatants, as well as the civilian and cultural objects, to ensure a minimal consideration of some fundamental human rights and to limit the means and methods of warfare in accordance with the four customary cardinal principles, as considered by the International Court of Justice in its advisory opinion on the Legality of the Use of Nuclear Weapons: the principles of humanity, distinction, proportionality and military necessity. Without any pretense of being an exhaustive study on the subject, the purpose of this article is to offer introductory insight into the international law of naval warfare.

Full textAbstract:
The War of the Pacific (1879–84) showcases the development of amphibious warfare during a period of industrialization and technological flux. Historians have traditionally framed Chilean victory in the war as a function of seapower: naval superiority from which victory on land followed as a result. This view underestimates the complex and reciprocal interplay of amphibious and naval operations throughout the conflict. The war can be better understood as a campaign of port hopping, enabled by maritime capacity and naval power, but reliant on amphibious elements to achieve political results and sustain Chilean sea control. In exploring the relationship(s) between amphibious and naval operations in the War of the Pacific, this article historicizes the emergence of modern amphibious warfare as a component of seapower in the industrial era.

Full textAbstract:
What Huizinga is saying here is not that conflict is playful, but rather, it is a game, following set rules of conduct and occurs within a defined zone of action. Elsewhere in Homo ludens, he argues that modern warfare operates without the ritualised, rule-based structure of, for example, the mediaeval tourney. The purpose of this paper is to consider the ways in which a model based on the structure of games may help us better engage with the challenges of Multi-Domain Conflict. We are all familiar with the concept of Cyber as the 5th Domain of warfare, but we need to consider it not as a discrete zone, but as running through and interpenetrating the other 4 (Earth, Sea, Air, Space), the informational spine that enables all other forms of conflict. This paper will: 1. Discuss the developing concept of Multi-Domain Conflict as a move ‘beyond jointery’ (as General Sir Nick Carter put it) into a truly integrated form of warfare, blurring and collapsing boundaries between kinetic and non-kinetic, between the services, and between military and civilian authority; 2. Outline a theoretical model for conceptualising Multi-Domain Conflict as gamelike in form, with environments of operation (‘boards’), protagonists (‘players’), and possible forms of action (‘moves’). As befits a conference on Cyber and Information Warfare, it will argue that the D5 model of IW (Deny, Disrupt, Degrade, Deceive and Destroy) is portable and scalable across the other 4 domains (Land, Sea, Air, Space); 3. Show how this theoretical model can be employed both to model and simulate Multi-Domain Conflict; wargames have been a key element of military planning and training for at least a century – this paper argues that we need to develop a new Kriegspiel to better understand coming conflicts.

Full textAbstract:
Carl Schmitt's personal history was notoriously closely linked to Spain, a nation with which he also shared religious faith and therefore partly a culture of origin. But Schmitt's thought was linked to Spain for many other reasons, which made this country, for the German thinker, a very particular point of view on the destiny of the world. From the political predictions of Donoso Cortés, to the decline of Eurocentrism, to the elemental struggle between land and sea, to guerrilla warfare, the role of this Western European country remained pre-eminent for Schmitt in the history of civilization.

Approved for public release; distribution in unlimited.The Pentagon is planning to gradually increase the Navy's SEAL force over the next several years to meet increasing global demands. The move was authorized by the Office of the Secretary of Defense (OSD) in a program decision memorandum (PDM) in December 2002. The PDM, which directed the growth of Special Operations Forces across the board, called on the Navy to bring the equivalent of two new SEAL Teams to the force between FY-06 and FY-08. Even though funding has been allotted to this task, there may not be enough manpower to fill these slots. Training issues coupled with retention issues have brought the growth process to a standstill. The purpose of this thesis is to identify which major variables and/or combinations of small variables need to be changed in order to increase NSW enlisted SEAL manning. The three major areas that will be looked at are recruitment, training, and retention. The focus will be to determine where NSW can do better at managing personnel in these areas. The end product will be a detailed analysis that will offer suggestions for program changes that can be implemented to increase NSW forces while raising the quality of operators at the same time.

L’esercito italiano e la conquista della Catalogna (1808-1811)
Uno studio di Military Effectiveness nell’Europa napoleonica
Settori scientifico-disciplinari SPS/03 – M-STO/02
La ricerca ha lo scopo di ricostruire e valutare l’effettività militare dell’esercito italiano al servizio di Napoleone I. In primo luogo attraverso un’analisi statistica e strategica della costruzione, e del successivo impiego, dell’istituzione militare del Regno d’Italia durante gli anni della sua esistenza (1805-14); successivamente, è stato scelto un caso di studi particolarmente significativo, come la campagna di Catalogna (1808-11, nel contesto della guerra di Indipendenza spagnola), per poter valutare il contributo operazionale e tattico dei corpi inviati dal governo di Milano e la loro integrazione con l’apparato militare complessivo del Primo Impero.
La tesi ha voluto rispondere alla mancanza di studi sul comportamento in guerra dell’esercito italiano e, allo stesso tempo, introdurre nella storiografia militare italiana la metodologia di studi, d’origine anglosassone e ormai di tradizione trentennale, di Military Effectiveness.
La ricerca si è primariamente basata, oltre che sulla copiosa memorialistica a stampa italiana e francese, sulla documentazione d’archivio della Secrétairerie d’état impériale (Archives Nationales di Pierrefitte-sur-Seine, Parigi), del Ministère de la Guerre francese (Service historique de la Défence, di Vincennes, Parigi) e del Ministero della Guerra del Regno d’Italia (Archivio di Stato di Milano).
Dal punto di vista dei risultati è stato possibile verificare come l’esercito italiano abbia rappresentato, per Bonaparte, uno strumento duttile e di facile impiego, pur in un contesto di sostanziale marginalità numerica complessiva di fronte alle altre (e cospicue) forze messe in campo da parte dell’Impero e dei suoi altri Stati satellite e alleati. Per quanto riguarda la campagna di conquista della Catalogna è stato invece possibile appurare il fondamentale contributo dato dal contingente italiano, sotto i punti di vista operazionale e tattico, per la buona riuscita dell’invasione; questo primariamente grazie alle elevate caratteristiche generali mostrate dallo stesso, ma anche per peculiarità disciplinari e organizzative che resero i corpi italiani adatti a operazioni particolarmente aggressive.The Italian Army and the Conquest of Catalonia (1808-1811) A Study of Military Effectiveness in Napoleonic Europe Academic Fields and Disciplines SPS/03 – M-STO/02 The research has the purpose of reconstruct and evaluate the military effectiveness of the Italian Army existed under the reign of Napoleon I. Firstly through a statistic and strategic analysis of the development, and the following deployment, of the military institution of the Kingdom of Italy in the years of its existence (1805-14). Afterwards, a particularly significant case study was chosen, as the campaign of Catalonia (1808-11, in the context of the Peninsular War), in order to assess the operational and tactical contribution of the regiments sent by the Government of Milan and their integration in the overall military apparatus of the First Empire. The thesis wanted to respond to the lack of studies on the Italian army’s behavior in war and, at the same time, to introduce the methodology of the Military Effectiveness Studies (of British and American origin and, by now, enriched by a thirty-year old tradition) in the Italian historiography. The research is primarily based, besides the numerous memoirs of the Italian and French veterans, on the archive documentation of the Secrétairerie d’état impériale (Archives Nationales of Pierrefitte-sur-Seine, Paris), of the French Ministère de la Guerre (Service historique de la Défence, of Vincennes, Paris) and of the Italian Ministero della Guerra (Archivio di Stato di Milano). About the results, it has been verified how the Italian army has become a flexible and suitable instrument for Bonaparte, albeit in a context of substantial overall numerical marginality in comparison to the heterogeneous forces available to the Empire and its others satellites and allied states. Regarding the campaign of Catalonia, instead, it was possible to ascertain the fundamental contribution of the Italian regiments, in an operational and tactical perspective, for the success of the invasion. This was primarily due to the excellent general characteristics shown by the expeditionary force, but also to disciplinary and organizational peculiarities that have made the Italian corps suitable for particularly aggressive operations.

Full textAbstract:
Disruptive technologies have transformed conflict at sea, creating a dynamic and distributed operational environment that extends from the oceans to encompass warfare on land, in the air, outer space, and cyberspace. Naval warfare throughout this integrated multi-domain, networked seascape raises choice of law decisions that include the law of naval warfare and the law of armed conflict; neutrality law; and the peacetime regimes that apply to the oceans, airspace, outer space, and cyberspace. The international law in networked naval warfare must contend with autonomous vessels and aircraft, artificial intelligence, and long-range precision strike missiles that can close the “kill chain” at sea and beyond. The asymmetrical use of merchant ships and blockchain shipping in naval operations, opening the seabed as a new dimension of undersea warfare, and sophisticated attacks against submarine cables and space satellites pose new operational and legal dilemmas. Navigating this broader conception of the international law of naval warfare requires an understanding of emerging operational capabilities and concepts throughout the spectrum of conflict and the selection and integration of distinct legal regimes.

AbstractThe ability to employ force across the physical warfighting domains of air, land, maritime, and space is essential in contemporary conflict. In NATO doctrine, the term “joint operations” refers to military actions “in which elements of at least two services participate.” While doctrinal definitions differ slightly across Western militaries, the basic premise remains that “jointness” in military operations entails significant action in at least two of the physical warfighting domains. This chapter provides an overview of joint warfare, beginning with a brief discussion of its development over the past century. It then turns its attention to the development of joint doctrine and the joint functions. It concludes with a brief discussion of what some military theorists see as the next iteration of joint warfighting: multi-domain operations (MDO).

This chapter explains the rationale for the volume, arguing that historical studies of economic warfare require greater nuance than has traditionally been afforded by an overreliance on conceptions developed by classical naval theorists such as Alfred Thayer Mahan. It presents an overview of the chapters in this collection, which are grouped around four key themes: neutrals and neutrality; the role of non-naval bureaucracies in conducting campaigns of economic warfare; the ways in which non-state actors have interacted with and taken advantage of episodes of economic warfare; and studies of economic warfare as an element in the broader grand strategy of states. The chapter concludes by offering suggestions for new approaches to understanding economic warfare and the sea. A more international approach which deconstructs the workings of the global economy promises rich rewards for new studies. Similarly, interrogating ideas about economic warfare, and the rhetoric surrounding its potency, may offer a better guide to understanding the reasons for its use in the past. Lastly, given that sea power matters chiefly in the ways in which it influences events on land, more must be done to excavate the link between action at sea and how it impinges on military operations on land.

Chapter 5 examines the weapons and logistical equipment warriors and soldiers in Europe, Africa, and the Americas deployed in warfare on land. The introduction of gunpowder weapons and the erection of new kinds of fortifications for artillery combat transformed warfare in Europe in the early modern era in a process often described as a military revolution. Nonetheless, Europeans did not possess any technological advantage in warfare in Africa or the Americas comparable to the supremacy ships gave them at sea. The chapter analyzes several technologies of war including firearms, poisoned arrows, canoes, and the use of dogs and horses in warfare.

It first provides an overview of the ways that physical geography influences the tactical identities of armed forces as well as their strategic effects, focusing on practices that lie at the heart of ‘joint’ warfare — in which land, sea, and air forces cooperate to their collective advantage. The discussion highlights the strategic possibilities presented by warfare in different physical environments — that is, land warfare, naval warfare, and air warfare. The chapter also considers the strengths and weaknesses of forces that fight on land and sea and in the air, unconventional warfare fought on land, the maritime strategy employed by navies, theory vs. practice of air power, and coercive bombing. Finally, it analyses the strategic potential of space war, the expansion of war into cyberspace, and the use of ‘cyber’ weapons in information warfare.

Full textAbstract:
This chapter examines ‘domains’ of warfare, which are generally understood as the operational environments in which armed conflict occurs, and to which international humanitarian law (IHL) therefore applies. Until recent decades, domains of armed conflict have been largely predicated on geospatial conceptions, denoting the physical places where armed conflict has customarily occurred: land, sea, and air. General IHL applies across all these areas—including the fundamental principles of humanity, military necessity, and proportionality; restrictions or prohibitions of certain means and methods of warfare; and basic rules requiring humane treatment of persons and respect for civilians and civilian property. Over time, however, the particular exigencies of land, sea, and air warfare have led to the development of some specific IHL rules and principles tailored to each of those environments. Discussing domains of armed conflict therefore offers a window into the historical development of IHL. It shows how the emergence of new operational environments and new means and methods of armed conflict catalyses efforts at legal regulation, which can lead to the development of new domains or sub-sets of IHL. The chapter then considers how the idea of a domain might apply to armed conflict in outer space, and armed conflict involving cyber operations and other emerging capabilities.

For decades air power has been the primary tool used by major powers to coerce recalcitrant opponents. Aircraft have fundamentally changed the conduct of war on land and at sea at the tactical level. The principles of deployment have changed little over the last century; only the technology has altered. ‘Foundations’ describes the four roles of air power: control of the air; intelligence, surveillance, and reconnaissance; attack; and mobility. Without a significant degree of control of the air, the other three elements are impossible to achieve. It also explains that military air operations exist within a number of physical and conceptual dimensions. First and foremost is logistics.

With today's changes in war doctrines, the areas where war is undertaken are highly diversified, in addition to the traditional land, air and, sea classifications. One of these areas is cyberspace, where all the activities are waged in this field by exploiting the advantages such as accessibility, availability, cheapness, convenience, anonymity, independence from distance and defense – attack asymmetry called cyberwarfare. Cyberwarfare is the use of cyberattacks by a state or an organization to cause harm to another state's or organization's computer information systems, computer networks and computer infrastructures in the context of warfare. The rationale behind these objectives is similar to other types of warfare, as cyberwarfare is both a dimension of actual warfare and stand-alone war area. In this chapter, cyberwarfare and related phenomena will be extensively discussed.

The Naval Surface Warfare Center, Carderock Division, Philadelphia Site successfully completed test and evaluation of the first gas turbine electric starter targeted for Navy use at the Land Based Engineering Site (LBES) of the Naval Surface Warfare Center, Carderock Division (NSWCCD). The Electric Start System (ESS) was developed and manufactured by Hamilton Sundstrand Corporation and installed on an LM2500 main propulsion engine. The ESS was successfully demonstrated to start an LM2500 marine gas turbine with the added benefits of reduced start system configuration (fewer components), ability to control engine acceleration during the early phase of the start cycle, functional transparency to the engine start logic, and speed synchronization between the ESS electric motor and the accessory gearbox of the LM2500 engine with no impact torque. To date it has accumulated over 30 successful starts on the engine. This paper will discuss the results of the aforementioned test, along with advantages and challenges of installing such a system aboard ship.

The Intercooled Recuperated Gas Turbine Engine System (ICR) is being developed by the United States Navy (USN) for shipboard application as a prime mover. The major development goal of the program is reduced fuel consumption relative to the LM2500, the current fielded gas turbine prime mover. This paper describes a 500-hour endurance test of the ICR system. The test was conducted at Naval Surface Warfare Center Carderock Division (NSWCCD), Philadelphia, in accordance with USN requirements which mimicked the qualification requirements for the system. Data to assess the capability of the ICR to pass the qualification test was collected. Overall, the ICR has demonstrated a readiness to commence qualification testing. The ICR completed the test with a total accumulated operating time of 457 hours and total endurance time of 322 hours. Achievement of the planned 500 endurance hours was precluded by persistent facility waterbrake problems.

Many Navies around the world have either committed to or are considering utilizing an integrated electric propulsion and ship service power system for their next generation of surface combatants. An integrated system provides for greater operational flexibility, efficiency, and survivability as described in Reference [1]. Two examples of this concept are the Type 45 Destroyer program for the Royal Navy and the DD (X) program for the US Navy. The machinery plant for the Type 45 will include both gas turbine and diesel generators sets, and although not determined yet, the DD (X) plant will undoubtedly include gas turbine prime movers. The US Navy has been evaluating a gas turbine generator based Integrated Power System (IPS) architecture at the Land Based Engineering Site (LBES) at the Naval Surface Warfare Center, Ship Systems Engineering Station (NSWCCD-SSES) in Philadelphia, Pa since 1999. This paper will describe the IPS configuration, test program, gas turbine generators, gas turbine generator operational experience, and recommendations for future systems.

Full textAbstract:
Recent breakthroughs in the field of hydrocarbon fuel electrostatic charging techniques have now permitted the opportunity for the Navy to consider implementing this technology into shipboard gas turbines. This research effort is focused toward electrostatic atomization insertion into a U.S. Navy Shipboard Rolls Royce Corporation 501-K research engine at the Naval Surface Warfare Center, Carderock Division (NSWCCD). Specific milestones achieved thus far include: (a) Spray demonstration of an electrostatically boosted 501-K gas turbine fuel injector prototype at fuel flows from 40 PPH to 250 PPH. (b) Electrostatic charging effect measurements on the droplet size and patternation of a 501-K simplex atomizer configuration. (c) Numerical modeling of the influence electrostatic charging has on secondary atomization breakup and predicted particulate emissions. This paper documents results associated with injector conceptual design, electrode integration, atomization measurements, numerical modeling and fuel injection system integration. Preliminary results indicate electrostatic boosting may be capable of reducing particulate emissions up to 80% by inserting the appropriate fuel injector.

Impact Technologies developed a model-based decision support Framework that facilitates the use and development of decision support tools in a CBM environment. The Framework leverages existing CBM and PHM data to provide enhanced automated strategic analysis. Its modular structure promotes reusability of components to expedite development of new decision capabilities, making it extensible to many different operational environments. The Framework also embraces open architecture and standardized data interfaces for increased supportability and upgradeability. An advanced probability-based mission readiness forecasting and assessment tool developed by Impact Technologies for the U.S. Navy was used to illustrate how the proposed Framework facilitates the assembly of independent decision support tools to provide a high fidelity knowledge product. In this application the Framework combined three separate functional areas — a mission profile modeling tool, a system relational model, and a maintenance optimization module. The mission profile modeling tool provided the ability to create functional representations of multi-layered complex systems for any mode of operation, accounting for different machinery line-ups, redundancy, system-to-system interactions, and component and sub-system criticalities. The system relational model provided the overall system probability of failure calculated based on the current and projected system configuration and usage. The maintenance optimization module determined the safest and most cost-effective time to perform required and opportunistic maintenance. The resulting software product enables the comparison of multiple what-if scenarios where the scheduling of maintenance and logistics support activities can be optimized based on resource availability and the propagation effects of those actions can be measured in terms of readiness at any level within the system hierarchy. A visual assessment of the ship’s probability of completing the prescribed mission of any combination of ship operations (e.g., anti-surface warfare, non-combat operations, or mine warfare) can be generated so corrective actions in the form of maintenance or changes to mission operations can be evaluated. The tool incorporates several novel approaches including fusion of multiple independent low-level indicators to predict overall system readiness, methodologies to account for the interactive effects of interconnected subsystems, and a risk-based optimization to select and schedule the optimal maintenance schedule. This paper summarizes the features of the model-based decision support tool Framework and the mission readiness software application developed using this architecture.

The US Navy has been researching integrated electric propulsion systems for many years. The economic advantages of the integrated electric architecture, where power for propulsion as well as ship service are derived from a common set of generators, are well recognized and such systems are used throughout many sectors of the commercial marine industry today. In addition to the economic advantages, there are military benefits to the ship when an Integrated Power System (IPS) architecture is adopted. Those include increased reliability and survivability, reduced signatures and increased upgradeability. A full scale Land Based Engineering Site (LBES) was constructed at the Advanced Propulsion and Power Generation Test Site (APPGTS) of the Naval Surface Warfare Center, Carderock Division – Ship Systems Engineering Station (NSWCCD-SSES) in Philadelphia, Pa, to demonstrate the system architecture and feasibility of chosen technologies for a warship application. This paper will describe the IPS, test site construction, and test operational experience with a GE LM2500 engine, utilizing a Woodward Governor Company (WGC) MicroNet controller, as the prime mover for the main generator set.

Full textAbstract:
Accurate prognostic models and associated algorithms that are capable of predicting future component failure rates or performance degradation rates for shipboard propulsion systems are critical for optimizing the timing of recurring maintenance actions. As part of the Naval maintenance philosophy on Condition Based Maintenance (CBM), prognostic algorithms are being developed for gas turbine applications that utilize state-of-the-art probabilistic modeling and analysis technologies. Naval Surface Warfare Center, Carderock Division (NSWCCD) Code 9334 has continued interest in investigating methods for implementing CBM algorithms to modify gas turbine preventative maintenance in such areas as internal crank wash, fuel nozzles and lube oil filter replacement. This paper will discuss a prognostic modeling approach developed for the LM2500 and Allison 501-K17 gas turbines based on the combination of probabilistic analysis and fouling test results obtained from NSWCCD in Philadelphia. In this application, the prognostic module is used to assess and predict compressor performance degradation rates due to salt deposit ingestion. From this information, the optimum time for on-line waterwashing or crank washing from a cost/benefit standpoint is determined.

Full textAbstract:
The U.S. Navy has incorporated a realm of new technologies into ship warfare in the last few years. This availability has led to advances in ship machinery systems that have enabled the Navy to improve and sustain its mission capabilities. Since 2003, the Navy has worked with manufacturers to develop, test and evaluate a gas turbine electric starter system (GT-ESS) capable of meeting all starting requirements of the General Electric LM2500 marine gas turbine. This engine is used on U.S. Navy Surface Combatants for vessel propulsion. The GT-ESS has also been used to start a newly acquired naval engine from Rolls Royce, the MT30. The GT-ESS has endured extensive test and evaluation at the Land Based Engineering Site (LBES) of the Naval Surface Warfare Center, Carderock Division in Philadelphia, PA. Throughout this time the system has been redesigned as well to comply with more restrictive shipboard requirements. This effort had a direct impact on the packaging of the system. Additional effort has been directed to machinery integration. Full integration of the GT-ESS onto the LM2500 engine entails sharing a common lubrication and cooling loop. This is a challenge for the engine since its lubrication is critical for its service life. It poses a challenge for the GT-ESS since its design must guarantee that the lubrication system will remain free of contamination. The GT-ESS also poses integration challenges for a ship installation. The ideal location of the GT-ESS in the ship is adjacent to the propulsion engine within the machinery room space. Switchboards that provide power to the system are located several decks above the machinery space. Additionally, dedicated power supplies are required to handle the power requirements of the GT-ESS. Thus this power demand calls for an assessment of the power loads onboard ship. This new technology also has an impact on other ship systems. The GT-ESS driver is water cooled and designed to feed from the chill water system of the ship. Its electric motor lubrication has ties with another naval technology (digital fuel control). In turn these two are tied to the lube oil system and conditioning assembly (LOSCA) of the engine. Thus issues of oil pressure, temperature, backpressure, suction, and starvation are addressed and assessed. This paper explores the impact of ship machinery design for ship installation and its impact on other machinery systems as well as ship’s power. It targets proper hardware packaging as a means to achieve a well balanced design for ship application.

Full textAbstract:
Naval Surface Warfare Center, Carderock Division - Ship Systems Engineering Station (NSWCCD-SSES) successfully completed testing of a new Full Authority Digital Control (FADC) system for gas turbine control. This system will be back-fit onto Model 139 Ship Service Gas Turbine Generator Sets (SSGTGs) on the U.S. Navy’s Ticonderoga (CG-47) class cruisers. The FADC will be a direct replacement of the original Model 139 Local Operating Panel (LOCOP) and will control the Allison 501-K17 gas turbine. The new control system provides for standardized installation across a wide variety of existing configurations. The development program leveraged off of the design work done for the AG9140 FADC currently being installed on DDG 51 Class ships. The result was a state-of-the-art system ready for shipboard installation in a short period of time, providing commonality of look and feel across platforms. This paper describes the CG-47 FADC and details the development and testing conducted on a Model 139 SSGTG at the NSWCCD-SSES DDG 51 Gas Turbine Land Based Engineering Test Site (LBES). The test program included all modes of SSGTG operation, including starts, shutdowns, and generator operations under varying load conditions.

Full textAbstract:
As part of the Gas Turbine Condition Based Maintenance (CBM) Program, Naval Surface Warfare Center, Carderock Division Code 9334 conducted compressor fouling testing on the General Electric LM2500 and Rolls Royce/Allison 501-K Series gas turbines. The objective of these tests was to determine the feasibility of quantifying compressor performance degradation using existing and/or added engine sensors. The end goal of these tests will be to implement an algorithm in the Navy Fleet that will determine the optimum time to detergent crank wash each gas turbine based upon compressor health, fuel economy and other factors which must be determined. Fouling tests were conducted at the Land Based Engineering Site (LBES). For each gas turbine, the test plan that was utilized consisted of injecting a salt solution into the gas turbine inlet, gathering compressor performance and fuel economy data, analyzing the data to verify sensor trends, and assessing the usefulness of each parameter in determining compressor and overall gas turbine health. Based upon data collected during these fouling tests, it seems feasible to accomplish the end goal. Impact Technologies, who analyzed the data sets for both of these fouling tests, has developed a prognostic modeling approach for each of these gas turbines using a combination of the data and probabilistic analysis.
