Повний текст джерелаInspection and Maintenance are important aspects when considering the availability of aircraft for revenue flights. Modern airframe design is exploiting new exciting developments in materials and structures to construct ever more efficient air vehicle able to enable efficient maintenance. The improvement in the aircraft safety by advanced structures and protecting nanofillers is a revolutionary approach that should lead to the creation of novel generation of multifunctional aircraft materials with strongly desired properties and design flexibilities. In recent years, the development of new nanostructured materials has enabled an evolving shift from single purpose materials to multifunctional systems that can provide greater value than the base materials alone; these materials possess attributes beyond the basic strength and stiffness that typically drive the science and engineering of the material for structural systems. Structural materials can be designed to have integrated electrical, electromagnetic, flame resistance, and possibly other functionalities that work in synergy to provide advantages that reach beyond that of the sum of the individual capabilities. Materials of this kind have tremendous potential to impact future structural performance by reducing size, weight, cost, power consumption and complexity while improving efficiency, safety and versatility. It is a well-known fact that, actually, also a very advanced design of an aircraft has to take required inspection intervals into account. An aircraft with inherent protective abilities could help to significantly extend the inspection intervals, thereby increasing aircraft availability. The challenge in this research is to develop and apply a multifunctional composite for structural applications. The aim of this project is the formulation, preparation and characterization of structural thermosetting composites containing dispersed protective nanofillers. This project specifically targets composites tailored for multifunctional applications such as lightning strike protection, and flame resistance. These composites were designed to enable their application on next generation aircrafts. With regard to the objectives of this PhD project the multifunctional composite systems were developed with the aim of overcoming the following drawbacks of the composite materials: • reduced electrical conductivity; • poor flame resistance. The thermosetting material was projected considering compatibility criteria so that to integrate different functions into a material that is capable of bearing mechanical loads and serves as a structural material element.

Повний текст джерелаAn electro-thermal anti-ice system was simulated with a mathematical model developed in the present work. A 44.7 m/s (100 mph) and 89.4 m/s (200 mph) full potential flow around a 0.914 m (3 ft) chord NACA0012 airfoil with 0° angle of attack and the local water catch efficiency of 20 μm median volumetric diameter droplets impingement were calculated by the numerical code ONERA2D. Four test conditions were simulated with four different heat flux distributions of the anti-ice system according to the experimental work developed at NASA. The model predicted distributions of solid surface and liquid water film temperatures, runback water flow and convection heat transfer coefficient between airfoil or water surface and gaseous flow. The simulated results obtained by the mathematical model developed were compared to NASA experimental results and the ones predicted by the numerical codes LEWICE/ANTICE (US) and CANICE (Canada). For the regions wetted by the water film, the present model provided 2.6°C maximum temperature deviations between the predicted results and experimental data. For the dry regions, where there is no liquid water on the airfoil surface, an 8°C maximum temperature deviation was obtained. The runback flow and water film ending point position were compared to LEWICE/ANTICE numerical results. The developed model predicts adequately the convection heat and mass transfer effects between the non-isothermal airfoil or liquid water film surface and the gaseous flow, as well the effects of laminar to turbulent flow transition within dynamic and thermal boundary layer and the influence of the liquid water film flow on the anti-ice system performance.

Повний текст джерелаUnlike any other movable property, ships, aircraft and space objects that are engaged in international navigation are linked to a State. The legal connection established between these craft/vessels and the State is commonly referred to as “nationality”. However, in this case the term does not represent an institution identical in all respects to the nationality of persons. With regard to vessels, the legal connection to a State is not based on factual elements (such as birth, descent etc.), but merely on the internal administrative act of registration. The study of State practice, notably international conventions and national laws, clearly shows that – contrary to what is often argued – there is no need to make this connection dependent on a pre-existing effective link. What matters most, given that these craft navigate in international space beyond the territorial jurisdiction of sovereign States, is to identify the State that holds sole jurisdiction over said “organized entity” consisting of the vehicle, the persons and the cargo on board and that is responsible for its activities. Public international law therefore prohibits dual registration, but leaves States free to determine the conditions under which they will confer their “nationality”, without imposing any other requirement for the opposability of this legal bond to third States. The danger is that this situation encourages laxity on the part of the States of registry and therefore creates the potential for serious damage incurred by persons involved in these vessels’ activities and – mostly – by third persons. In this regard, it is the international obligations and corresponding rights of the States of registry which are critical, and not a mysterious “effectiveness” of the legal bond. In other words, it is not necessary to impose on the State of registry any international conditions which would limit its freedom with regard to the conferral of its “nationality” upon vessels. It is however indispensable to require that said State complies with its obligations, meaning that it has to effectively exercise its jurisdiction and control over those craft. This statement holds true regardless of the craft concerned. The legal bond created by the registration therefore constitutes a "sui generis" institution, common to ships, aircraft and space objects, and whose legal regime is governed by international law

Aircraft shelters are the main targets for the enemy attacks at the airport during wartime. In order to reduce the damage to the aircrafts from the direct Air-Strike or indirect explosion debris;The construction of Hardened Aircraft Shelter (HAS)has already become the first priority of Air-Defense subjects for Taiwan. Most of the air bases at Taiwan are close by sea, without the protection by appropriate facility; the “Operational Readiness” of Avionics System will be suffered by the influences of temperature, humidity, salt, and acid rain...etc. Currently some of the bases have to operate the aircrafts on the apron, because of not having sufficient HASs, and tie-bar exposes, and debris shed off, from the roof of shelter. To ensure the Operational Readiness during shelf-life and survivability at war time, referring the newly designed HAS by USAF, and NATO, could be a good connect for reconstruction. This research is base on the following factors, such as storage environment, the probability of (none) direct hit during wartime, Destruction Mode, and Cost Effectiveness, of cost efficiency etc. The objects for analysis include the traditional RC HAS, hangar, underground tunnel, and the new steel arch shelter. Finally, consult and deliberate the efficiency and the protection strategy of the HAS around the world, and consider the finance status of country;compare with the investment, period of working days, and benefits, choose one of the best options.

Повний текст джерелаOn this dissertation, the usage of Unmanned Aircraft Systems (UAS) Commercial off the shelf (COTS) in combat/terrorism actions is analysed, referring its advantages and disadvantages, and the potential threat posed by it to Harbour Protection is defined. It is studied what are Counter-UAS (C-UAS) systems, understanding how they work against UAS, and it is gathered information about C-UAS doctrine already in use by military forces. During this dissertation it had been executed real tests using UAS and warships moored at Lisbon Naval Base, in order to confirm the attacking systems’ capabilities and the reactions against them, and it had been given some contribution to the elaboration of Tactics, Techniques and Procedures (TTP) that are being promulgated on Portuguese Navy. This dissertation´s result is a proposal of some measures to be adopted in order to help to counteract the use of UAS COTS in offensive operations against moored or anchored ships and units, installations and infrastructures located in harbours.

The purposes of this study are to establish a model for understanding satisfaction of residents and its relative factors about the protections of aircraft noise, and to give suggestions for administrative authorities. The sample elements are drawn from those households where located in the third and the second aircraft noise control areas of Taipei Song Shan airport and the second aircraft noise control area of Kaohsiung Hsiao Kang airport. By using simple random sampling, 300 samples were selected among each area. The data were collected via interview with the total 879 valid questionnaire. Frequency distribution, correlation, multiple regression, and path analysis are used in the data analysis. The major results of this study are as follows: 1. The residents were influenced severely by aircraft noise. 2. Most of the residents are unsatisfied with those protections, and misunderstand what those protections are, and have many needs of the protection. 3. Policy awareness and expectation directly influence residents'' satisfaction. The more awareness and less expectation, the more satisfaction. 4. The expectation of airport noise protection is influenced by cost-benefit assessment. People who have higher benefit perception, lower risk perception, and lower knowledge have lower policy expectation. 5. The knowledge of airport noise protection is influenced by benefit perception. The higher benefit perception, the more awareness of the protection policy. 6. The satisfaction of protections will be reflected on the political statement activity and residents'' moving. It is found that the satisfaction of noise control is the primary cause. 7. The cost-benefit assessment can influence the satisfaction indirectly. Risk perception is the most influential factor. 8. Demographic factors have significant but low influence on major variables. 9. The most important protection is policy of noise resource control because of a causal chain from noise resource to the political statement activity and residents'' moving. This causal chain includes noise resource influences risk perception, risk perception has major impact on expectation of protections, expectation has important influence on satisfaction of protections, and the satisfaction is the major reason of the political statement activity and residents'' moving. 10. The model is designed to explain the residents'' satisfaction of the protections on aircraft noise and fits well. To conclusion, follows are some suggestions for political authorities including: to effectively reduce the noise resources, to increase benefit perception, to communicate well with residents, to set the noise control areas properly, to soundproof the house, to do what residents need, to improve the quality of policy, and to give information about noise.

Data Envelopment Analysis (DEA) is one of performance evaluation methods applying multiple inputs and multiple outputs from targeted decision making units (DMU). Traditional DEA models can only separate efficiency DMUs from non-efficiency DMUs. When one wants to completely rank DMUs or design alternatives, advanced DEA methods might be needed for this purpose. In addition to traditional DEA models, several advanced DEA models are needed for completely ranking design alternatives. The aircraft industry is technology-intensive, experience-intensive and capital-intensive. The aircraft engine accounts for about 30% of the total aircraft product value. The aircraft engine protection system is a key device to preventing aircrafts from malfunction. When designing the engine protection systems, the designer should consider many important factors such as reliability factor, cost factor, volume factor, weigh factor, and satisfactory factor. Using many combinations of design factors, the designer wants to know how to evaluate the best one among all design alternatives by DEA models. In this study, CCR model and BCC model are used to differentiate those efficiency and non-efficiency design alternatives. Then six advanced DEA models, including Andersen and Petersen model, Cross Efficiency model, Aggressive Cross Efficiency model, Benevolent Cross Efficiency model, Cross Reference model, and Common Weight, are analyzed and applied to completely rank those design alternatives. The study results suggest that Andersen and Petersen model and Cross Reference model give a consistent assessment result. On the other hand, Cross Efficiency model, Aggressive Cross Efficiency model and Benevolent Cross Efficiency model show a peculiar ranking result. Common Weight model can not provide a complete rank and need further investigation.
