Abstract:
This article focuses on the developments in materials, production methods, and turbine designs that have spawned a new class of jets. Cessna’s Citation Mustang became the first very light jet to reach commercialization. According to market leaders, the development of computerized cockpits with simplified displays has also been huge. Composites also let engineers combine lots of parts—panels, framing, rivets—into a single part. The fewer parts, the easier and cheaper it is to assemble and the more reliable the finished airplane. Every aerospace company is looking for bolt-on components that simplify assembly and maintenance. Adam Aircraft seeks to simplify production by making large composite parts. The second mechanical advance that makes very light jets possible is the compact, reliable turbofan. While Pratt is well-known for huge turbines that power commercial passenger jets, the company produces several small turbines. Pratt uses blisks and other technologies to simplify production. The result is a new type of jet, one that makes jet airplanes far more affordable.

Abstract:
In the aerospace industry, each year several commercial airplanes stop its service to carry out detailed routine inspections of their structural members and systems, including the power plant. Among several maintenance services to be performed in an airplane during a check, the corrosion prevention and control program is the one of the most important service since it includes methods of inspection and tasks to prevent corrosion in all airplane structural areas, such as fuselage, wings, stabilizers, flight control surfaces etc. During routine inspections, upon discrepancy detection, some actions must be immediately taken in order to correct the problem and avoid the loss of airplane structural strength. The corrosion removal from any aircraft structural member, in general consists in blending out the damage and carry out a visual and ND inspection (e.g. remaining thickness measurement by ultrasonic test). However, all care must be taken during remaining thickness measurement since systematic and random errors can affect in the results, compromising the final quality of measured parts. The main purpose of this paper is to perform an experimental study of remaining thickness measurement in an aircraft outer wing skin after corrosion removal, objecting to determine the uncertainty sources of the usual method. Also, the study intends to determine the expanded uncertainty in order to purpose a new methodology for the metrological treatment of this process, establishing a conformity zone.

Abstract:
Purpose Additive manufacturing technology, also commonly called as 3D printing technology, is entering rapidly into the aerospace world and seems to be its future. Many manufacturing processes are replaced by this technology because the ease of use, low costs and new possibilities to make complicated parts. However, there are only few solutions which present manufacturing of structurally critical parts. Design/methodology/approach Complete process of deriving loads, design of fitting geometry, numerical validation, manufacturing and strength testing was presented. The emphasis was made to show specific features of 3D technology in printed fittings for UAV. Findings The research confirms that the technology can be used for the application of fittings manufacturing. Attention needs to be paid, during the design process, to account for specific features of the 3D printing technology, which is described in details. Practical implications Without a doubt, additive manufacturing is useful for manufacturing complicated parts within limited time and with reduction cost. It was also shown that the manufactured parts can be used for highly loaded structures. Originality/value The paper shows how additive manufacturing technology can be used to produce significantly loaded parts of airplanes’ structure. Only few such examples were presented till now.

The UL-39 Albi university's all-composite ultralight aircraft project, powered by a piston engine and ducted fan, continues at the Department of Aerospace Engineering at Faculty of Mechanical Engineering CTU in Prague and its partners ZALL JIHLAVAN airplanes, s.r.o. and LA composite, s.r.o. by developing its new generation. The article is a follow-up to a contribution from 2017, where the entire genesis of the first prototype was described. The introduction summarizes the experience of the prototype operation and analyzes the deficiencies that required a major redesign of the propulsion unit. Aspects leading to the choice of another propulsion unit arrangement and changes in the ducted fan, airframe and systems are described. The fuselage of the airplane has undergone a dominant change. The paper describes not only structural changes leading to the reduction of the width of the fuselage and its wetted area, but also the changes in manufacturing process of composite parts leading to weight reduction. Following the changes in the fuselage design modifications of the wing (mainly high lift devices) and modification of the horizontal tail plane are described. At the end there is a plan of further development described, which should ultimately lead to the commercialization of the project.

Abstract:
Airspace industry components frequently need high added value part including some featuredifficult to manufacture. One of the best example is the thin walls of parts (airplanes frames orthe turbine blades) that have a very low stiffness. The finishing operations for high height to thicknessratio parts lead to chatter vibrations, unacceptable dimensional errors or poor surface finish. The optimalmachining strategy determination is often based on trial and error and may not be cost effective(acceptable conditions can be far from the optimum). Simulation of the milling process is a powerfulmean to accelerate the search for better cutting parameters. Cutting forces, vibrations, geometricerrors or roughness can be predicted before the production of the first parts. The classical mechanisticapproach is even though limited while machining flexible parts because the dynamic response ofthe workpiece changes with the position of the cutter. The objective of this paper is to demonstratethe adaptation of numerical simulation of milling operation for the machining of thin-walled plates.Three complementary approaches are developed: location-dependent stability lobes, quasi static approachand full dynamic simulation. Location dependent stability lobes extend the classical theoryto take into account the variation of dynamic response along the workpiece. Quasi static approach isintended to deal with form error during chatter-free machining operations. Full dynamic simulation isa more complex approach intended to simulate the behavior of the complete tool/machine/workpiecesystem. The numerical approach is compared to experimental tests performed on thin plate of titaniumalloys.

Abstract:
Background: Travel poses a risk for transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other respiratory viruses. Poorly ventilated indoor settings pose a particularly high risk for transmission. Methods: We used carbon dioxide measurements to assess adequacy of ventilation during 5 trips that included air travel. During selected parts of each trip that involved indoor settings, we monitored carbon dioxide levels every 1 minute and recorded peak levels and the number of people present. Carbon dioxide readings above 800 parts per million (ppm) were considered an indicator of suboptimal ventilation. Results: Carbon dioxide levels remained below 800 ppm during train rides to and from the airport and inside airports except in a crowded boarding area with ~300 people present. Carbon dioxide levels exceeded 800 ppm inside the airplanes, but the air was filtered with high efficiency particulate air filters. Carbon dioxide levels remained below 800 ppm in common areas of a hotel but exceeded 800 ppm in a hotel room with 2 to 3 occupants and in a fitness center with 3 people exercising. In restaurants, carbon dioxide levels increased above 800 ppm during crowded conditions with 24 or more people present and 75% or more seat occupancy. Conclusion: Our results suggest that ventilation may be sufficient to minimize the risk for airborne transmission in many situations during travel. However, ventilation may be suboptimal in some areas or under certain conditions such as in hotel rooms or when restaurants, fitness centers, or airplane boarding areas are crowded. There is a need for larger scale studies to assess the quality of ventilation in a wide range of community settings.

Abstract:
Through continued innovation and growth, traveling wave tube amplifiers (TWTAs) remains the microwave power amplifiers of choice in a wide range of high power microwave and millimeter-wave applications specifically for aerospace applications with the volume, weight, bandwidth and power constraints. These advances can be credited to device innovation, improved modeling and design and development of advanced materials and construction techniques. This thesis aims at advancing the present technology of TWTs with coupled resonator slow-wave structures (SWSs) by a combination of device innovation, development of enhanced analytical and field analysis codes and understanding gained through improved modeling, simulation and experimentation. In a TWT, the SWS that slows the RF wave velocity down to near the electron beam velocity for interaction with the electron beam primarily determines the microwave performances of the tube. As compared to helix SWS, the coupled resonator SWS is capable of handling high peak and average powers with higher efficiency and TWTs based on these SWS are well suited for air-borne or space-borne radar systems and the major focus of this thesis is on the analysis and design of coupled resonator SWSs. As a part of this thesis, improved analytical codes based on quasi-TEM analysis and equivalent circuit analysis have been developed. The technical formulation is explained and the improvements made for enhanced accuracy and for incorporation of different types of coupled resonator SWSs detailed. Using these models new variants of coupled resonator SWSs have been investigated. The SWSs proposed are the ladder-core inverted slot mode SWS and the inductively loaded inter digital SWS (ILID-SWS). The possibility of achieving both coalesced mode design that gives wide bandwidth and multi beam design that improves the peak power and gain using rectangular ILID-SWS is presented. The properties of these proposed SWSs have been compared with the existing SWSs and found to give superior performance. Also an improved modeling and simulation technique using 3-D electromagnetic codes has been proposed and the conventional cold test measurement procedure has been modified for more accurate results. Numerous illustrative examples are presented throughout the thesis highlighting the analytical model and simulation code validation with experimental results. The experimentations have been carried out on the real SWS model that have been fabricated and assembled. Further, the contribution of the thesis is towards the development of a field analysis model for analysis of a corrugated waveguide SWS, based on the coupled integral equation technique (CIET), which is a combination of mode matching technique (MMT) and method of moments. The technical formulation and computational methodology employed in the model are explained and some of the most important aspects of implementation like the handling of singularities and choice of parameters controlling the accuracy is discussed. The accuracy and speed of the code is demonstrated by comparing CIET with MMT and 3-D electro magnetic simulators based on finite difference time domain (FDTD) method and finite element method (FEM). The CIET code developed is quite faster than the existing numerical methods and helps in solving the convergence problem associated with the MMT.

Abstract In order to protect military secretes, the relevantresearches for the maintenance of military planes and its logistics support of the airplane spare parts in Taiwan Air Force rarely involvedby the academic institutions. As a result, the maintenance staff can only follow the standard operating procedures under the supervision of their superiors. What key factors we firstly considered for logistics support in the air force maintenance operations. However, there are a few relevant research can be used as a reference. This study aims to propose the proper key factors of logistics support spare parts in airplane maintenance for expectation to improve the availability rate of the fighter planes. After investigated related references, we apply Delphi method to design questionnaires that include four dimensions, such as regularly replaced parts, regularly inspected parts, time limited parts, and consumable parts. We proposed several key factors for above 4 dimensions according to his practice experience for many years on the maintenance operation. The questionnaires completed through 4 rounds that were answered by the experts of Maintenance Sections in the Air Force. The results of questionnaire show the important factor ranking for each dimension, respectively. Finally, we found that the results are useful and can be feasible implement by the maintenance sections in the Air Force. Keywords: Logistics Support of Airplane Maintenance, Delphi Method, Material Management

There are several artifacts developed by taking inspiration from natural organisms and phenomena. For instance, Velcro was inspired by a plant burr, bullet- proof vests were inspired by spider silk, sonars were inspired by bats, airplanes were motivated by the flying of birds, and the list goes on. The observation of nature has also allowed the development of several laws and theories that describe how parts of nature work; the laws of physics are a great example – laws of thermodynamics (conservation, entropy, and absolute zero); laws of movement (Newton’s laws); laws of electromagnetism (Maxwell’s laws); and others. They are used to explain the trajectories, attraction and other aspects of objects.

Abstract:
Things used to be so simple. In the old days, a thousand generations ago or so, human technology wasn’t much more complicated than the twigs stripped of leaves that some chimpanzees use to fish in anthills. A large bone for a club, a pointed stick for digging, a sharp rock to scrape animal skins—such were mankind’s only tools for most of its history. Even after the appearance of more sophisticated, multipiece devices—the bow and arrow, the potter’s wheel, the ox-drawn cart—nothing was difficult to understand or decipher. The logic of a tool was clear upon inspection, or perhaps after a little experimentation. No longer. No single person can comprehend the entire workings of, say, a Boeing 747. Not its pilot, not its maintenance chief, not any of the thousands of engineers who worked upon its design. The aircraft contains six million individual parts assembled into hundreds of components and systems, each with a role to play in getting the 165-ton behemoth from Singapore to San Francisco or Sidney to Saskatoon. There are structural components such as the wings and the six sections that are joined together to form the fuselage. There are the four 21,000-horsepower Pratt & Whitney engines. The landing gear. The radar and navigation systems. The instrumentation and controls. The maintenance computers. The fire-fighting system. The emergency oxygen in case the cabin loses pressure. Understanding how and why just one subassembly works demands years of study, and even so, the comprehension never seems as palpable, as tangible, as real as the feel for flight one gets by building a few hundred paper airplanes and launching them across the schoolyard. Such complexity makes modern technology fundamentally different from anything that has gone before. Large, complex systems such as commercial airliners and nuclear power plants require large, complex organizations for their design, construction, and operation. This opens up the technology to a variety of social and organizational influences, such as the business factors described in chapter 3. More importantly, complex systems are not completely predictable.

Tourism is a fragmented and information-oriented sector covering tour operators, travel agencies, hotel sales representatives, associations, meeting offices, transportation, car rental, airlines, cruise, souvenirs, restaurants, hotels/motels, and entertainment. The car rental sector, which is an important part of the tourism sector, is growing day by day, and the number of customers is increasing rapidly. The success of the car rental sector, which produces support services within the growing tourism sector, is considered very important for the development of tourism. The COVID-19 pandemic has engulfed the globe and has already had an enormous impact on life as we once knew it. With airplanes grounded, millions of people in quarantine, and hundreds of travel bans in place, COVID-19 has brought the global tourism industry to a grinding halt along with the rental industry. The study determines the current situation of the car rental sector and presents some suggestions.

Chapter 4 concentrates on how people learned to be in and live with ordinary flight through the everyday sky. Focused on air passage itself, it explores how a flying culture took hold and examines the affective dimensions of airline travel. Analyzing air travel stories, it chronicles what first-generation fliers did and felt inside early airline cabins. The vertical distance between the airplane and the ground profoundly altered the ways air passengers related to colonial landscapes and lives beneath them. The second part of the chapter illuminates how black people on the ground reacted to white people in the sky, and vice versa. It connects the emergence of everyday air travel practices to the upward expansion of empire. The last part of the chapter brings the history of white flight and racial segregation to present-day discussions of aerial mobility and the varying experiences of frequent and infrequent fliers.

Abstract:
An ideological state project of assigning science achievements to that of Hindu mythologies is indirectly undermining democratic structures. Emergence of the fake news phenomenon within the current post-truth era has threatened India's state harmony. From its dominant role in the 2014 Lok Sabha elections to the 2016 U.S. presidential elections, fake news has become a political tool which was misused in both events. One of the major concerns with fake content creation appeared in its use by the central government to disregard science. Political leaders are achieving this by propagating fictional accounts of material inventions from mythological epics like the Mahabharata as the origin for modern scientific inventions like airplanes. Such fake content is part of Bharatiya Janata Party's (BJP) larger project directed towards creating a Hindu nation. These content are provided virality with the help of social media and online chat platforms like WhatsApp. The chapter tries to locate the role of the instant messaging application WhatsApp in establishing Hindu mythological achievements as the predecessor of modern science in India.

Abstract:
Since crises have become an inevitable, natural feature of the business world, managing brands during crisis has also become an important source of competitive advantage. Thus, there is a growing need to understand determinants of crisis, which have become an integral part of today's world. The aim of this chapter is to explain the determinants of successful brand management during crises based on the case of Turkey. Crises may arise for various reasons, such as natural disasters, accidents, financial/political/product harm-related problems, product recall incidents, and many others. Since brands are very affected by many dynamic forces—political-economic-social and technological—brand managers need to be prepared to overcome crises without harming the brand equity. Moreover, the integration of brand management theory, which originated and was dominated by Western researchers, with recent case examples from an emerging country, constitutes the originality of the chapter. In this chapter, two boycott cases, an airplane disaster case and a product recall case, from Turkey are summarized to contribute to the existing Western literature.

Abstract:
On my third evening in Russia, the world changed. I was in Stavropol, a city founded by Prince Gregory Potemkin at the time of the American Revolution as one of ten fortresses to defend the borders of the expanding Russian Empire. To the south were the Caucasus, formidable mountains and myriad peoples. Stavropol grew as an administrative center of tsarist and later Soviet power. It briefly fell to the Wehrmacht in 1942 as the invading army drove unsuccessfully toward the oilfields of Baku. Later, a popular young party secretary from the area got noticed in Moscow, joined the Politburo, and in 1985 became general secretary of the Communist Party of the Soviet Union. Mikhail Gorbachev’s reforms would inadvertently lead to a geopolitical earthquake, the end of the Cold War in Europe, and the unthinkable—the collapse of the Communist empire built by Lenin and Stalin. That evening the provost of Stavropol State University toasted the health of the international academics attending the conference starting the next morning. Many other benevolent toasts were exchanged, and a singularly somber one. A researcher with the Memorial Human Rights Center reminded us that a war raged nearby in Chechnya, an “inner abroad” of Russia. Here Russia’s new president had approved the indiscriminate shelling of a Russian city and a dirty war against citizens redefined as “terrorists.” Returning to our hotel that evening in a bus under armed guard, a Croatian friend and I were chatting when told to turn on the television. Russian television was broadcasting footage of airplanes crashing into skyscrapers in lower Manhattan on what seemed like a continuous loop. The full magnitude of what had happened was only apparent the next day. Like many, the Twin Towers were entwined with personal memories—first seeing them in rural Ireland on a pennant my uncle brought back from his vacation to New York, and later visiting the observation deck with my parents and friends. Furthermore, the attack on the Pentagon was only two miles from my home, a few more from where I worked, and all too close to some former students who worked in the building.

Abstract:
Abstract Complex mechanical products, such as automobiles and airplanes, must satisfy many customer requirements, commonly called Key Characteristics (KCs). Such products have many separate parts, all of which must cooperate to deliver these requirements. In many cases there are more requirements than degrees of freedom available to meet them all independently, requiring prioritization. This problem is called KC conflict. In a highly complex product, such conflicts can be difficult to detect during design. This paper defines this problem and shows how screw theory can be used to detect and potentially correct it.

Full text
Abstract:
Sheet metal assembly is a common manufacturing process for several products such as automobiles and airplanes. Since all manufacturing processes are affected by variation and products need to have a high geometric quality, geometry related production problems must be analyzed during early design phases. Often, the analysis is done by using FEA (Finite Element Analysis) to include the compliant behavior of the parts. There are many variables that affect the geometric quality and to include many of them in a FEA simulation is often very time-consuming. One way of performing the simulations relatively fast is to establish linear relationships between part deviation and assembly spring-back deviation by using Method of Influence Coefficient (MIC). However, one limitation with the method is that the method does not consider contact between the parts. This means that the parts are allowed to penetrate each other. In some cases when contact occurs, this method will not simulate the real behavior of the assembly. This paper presents a contact modeling technique that can be implemented in the MIC. The contact modeling procedure consists of a contact detection algorithm and a solution algorithm for finding the position of equilibrium. When implemented, the MIC still only requires two FEA calculations. This paper describes the steps in the contact algorithm and how it can be used in MIC, finally a case study is analyzed.

Full text
Abstract:
Abstract Bolted joints are used in many industrial products such as mechanical structures, automobiles, airplanes, chemical plants, and so on. In many cases, after the design of new products is finished, various tests on the bolt and bolted joints are carried out using actual parts to prevent accidents due to bolt loosening and fracture. At the same time, in the strength tests, external force measurement, axial bolt force measurement and so on are included. However, there are no advanced tests in which axial bolt strain distribution or bolt elongation in actual parts and so on are measured. Therefore, in this research, a new method for evaluating bolt strength characteristics using an optical fiber sensor system capable of measuring actual parts is demonstrated. First, a tensile strength test using an optical fiber sensor is carried out to measure strain distribution in a bolt, and a maximum strain value position in the measured clamp load-strain curve is shown. Then, the elongation at each part of the bolt is shown. Next, yield clamp bolt force is found using this sensor system in torque/clamp force testing. In addition, the measured yield clamp bolt force is compared with the values in the conventional measurement method and in the estimation formula. Also, discussed is the effective cross section area by which the stress at the engaged threads is calculated under tensile load. Finally, another case where an optical fiber sensor system is used for bolt fastening evaluation is discussed.

Abstract:
Compliant sheet metal assemblies are often used as support structures in automobiles, airplanes and appliances. These structures not only provide a metrology frame for other modules to be assembled, but also give the product its aesthetic form. For this reason, the dimension quality of the assemblies is a very important factor to control, in order to make sure that the product will function as planned and continuously keep the product cost low. The assembly is influenced by variations in the component parts and the assembly processes. Tolerance analysis, as conducted in most industries today, is normally based on the assumption of rigid parts and is thus not always valid for sheet metal assemblies, due to their compliance. This paper will present a method, based on finite element analysis (FEA) and design of computer experiments, of identifying the influence of input variables on the final geometry variation of the assembly. The influence and the interactions among the input variables are analyzed with a response model that has been constructed, using the simulation results. This response model could be used to identify the important variables that need to be controlled in assembly. An example application is included, in order to demonstrate the simulation model and response model construction. Analysis of the results from the simulations can facilitate the design of the assembly process, in order to control the dimensional quality of the product.

Abstract:
Most complex systems, including engineering systems such as cars, airplanes, and satellites, are the results of the interactions of many distinct entities working on different parts of the design. Decentralized systems constitute a special class of design under distributed environments. They are characterized as large and complex systems divided into several smaller entities that have autonomy in local optimization and decision-making. A primary issue in decentralized design processes is to ensure that the designers that are involved in the process converge to a single design solution that is optimal and meets the design requirements, while being acceptable to all the participants. This is made difficult by the strong interdependencies between the designers, which are usually characteristic of such systems. This paper proposes a critical review of standard techniques to modeling and solving decentralized design problems, and shows mathematically the challenges created by having multiobjective subsystems. A method based on set-based design is then proposed to alleviate some of these challenging issues. An illustration of its applicability is given in the form of the design of a space satellite.

Abstract:
Abstract Currently, it is possible to buy almost anything from books (Amazon.com) to airplane tickets (travelocity.com) using the world wide web. The purpose of this project is to explore the use of the web for the fabrication of mechanical prototype parts, i.e. parts that can be fabricated using standard machine tools like milling machines. The current mechanism for production of prototype parts requires a process of part description preparation, bidding, contract award, and finally fabrication and delivery of the part. This is a substantially more complex process than buying a book or an airplane ticket. In order to achieve “e-commerce” in this field it will be necessary to develop a “clean interface” between the design and fabrication of mechanical prototype parts. This requires an unambiguous description of the part along with an automated method for bidding on the job. A new system called FACILE (Fast Associative Clean Interface Language and Environment) has been proposed to meet this need.

Full text
Abstract:
Abstract Tribology — the science and engineering of friction, wear, and lubrication — enables the design of engineered systems with moving parts to achieve its intended functions. Many systems are so well designed already that they work as expected without requiring much attention, most of the time. However, when a system fails because of tribological problems, we may have a major disaster that may bring down the entire system, such as vehicles, engines, machinery, and even factories. Fortunately, the field of tribology has so far advanced, though often empirically, that many systems usually perform well. For instance, commercial airplanes are airborne for days without maintenance; windmills in the middle of the sea produce electricity for years; the tires of automobiles now last much longer than they used to, and machine tools make products for many months with minimal maintenance. Yet, there are still many unsolved tribology problems that require solutions. The ultimate goal of a tribological system is a life-time operation without any failure. The quality of design determines the performance of tribological systems. Tribological failures of the system may be avoided through rational and creative design. In that sense, there is a symbiotic relationship between tribology and design. Many tribology problems encountered are often the result of poor system design. By properly designing the tribological system, potential failures caused by friction and wear can be avoided or minimized. Continuous testing of poorly designed tribological systems, which occurs in some cases, can be costly and with no noticeable improvements in the system performance. Since well-designed products yield immense benefits, the creation of tribological systems based on rational design should be pursued. The biggest source of tribological problems is the coupling of the functional requirements (FRs) that are introduced in the early stages of design. Attempts should be made to eliminate coupled tribological systems to improve their performance.

Abstract:
The art and science of gas turbine has traditionally seen a gradual and continuous change over the past few decades. Gas turbines are classified into impulse and reaction types and further into turbojet, turbofan, turboprop, after burning turbojet and micro gas turbine. These turbines find applications in airplanes, large scale industries etc. but these are less suitable for the small scale power generation units due to several factors. Micro gas turbines are set to play a significant role particularly in small-scale power generation using combined heat and power generation among all these types of turbines as the future of power generation lies in decentralised and distributed power generation systems. In the light of making use of the high temperature exhaust of a gas turbine, combined heat and power generation systems are being used to increase the power output and overall efficiency. Micro gas turbines are essentially single-stage, single-shaft and low pressure gas turbines whose capacity ranges from 30–150 KW. In comparison to the conventional turbines, micro gas turbines are compact and have low lubricating oil consumption leading to a simpler lube and sump oil system and because they have fewer rotating parts, this leads to lesser balancing problems. The analysis of micro gas turbines has shown that they are capable of meeting current emission standards of NOx and other pollutants. Even though the installation costs of micro gas turbines are high due to the complexity in adjusting to electrical grid frequency, still these distributed energy systems may prove to be more attractive in a competitive market to those seeking increased reliability as they empower these entities with the capacity of self-generation. The following text reviews the developments in the micro gas turbines with a special focus on the efficiency of its components such as the recuperator, the combustion chamber design and also explores the future prospects of the technology in terms of viability of its application in the automobile sector.
