AbstractPreliminary aircraft design and cabin design are essential and well-established steps within the product development cycle for modern passenger aircraft. In practice, the execution usually takes place sequentially, with the preliminary design defining a basic cabin layout and the detail implementation following in a subsequent step. To enable higher fidelity assessment of the cabin early in the design process—for example by means of virtual reality applications—this paper proposes an interface, which can derive detailed 3D geometry of the fuselage from preliminary design data provided in the Common Parametric Aircraft Configuration Schema (CPACS). This is a key step towards integration of cabin analysis and preliminary design in automated collaborative aircraft design chains, not only in terms of passenger comfort, but also manufacturability or crash safety. Like the TiGL Geometry Library for CPACS, the interface presented acts as a parameter engine, which translates data from CPACS into CAD geometry using the Open Cascade Technology library. However, the scope of TiGL is expanded significantly, albeit with an explicit focus on the fuselage, by including more details such as extruded frame and stringer profiles and floor structures. Furthermore, advanced knowledge management techniques are employed to detect and augment missing data. For virtual reality applications, triangulated representations of the CAD geometry can be provided in established exchange formats, creating an interface to common visualization platforms. Additionally, a new evolution of the cabin definition schema in CPACS is presented, to incorporate models of cabin components such as seats or sidewall panels enabling immersive virtual mock-ups.

There is a duopoly in the global civil aircraft industry. The market for the production of passenger aircraft is mainly divided between companies such as Boeing and Airbus. This work describes the history of the creation and activities of both companies throughout their existence, as well as the trends in their activities today, related to external events. Competition between these companies is quite high and exists due to a number of certain factors. The results of this competition are the position of each of the companies in the market, which is reflected in their production and financial indicators and reflects the overall situation in the market for the production of civil aircraft. Also, this work allows us to identify future trends in the activities of these manufacturers, and, accordingly, the entire industry as a whole.

Abstract Reuse of retired aircraft is an intuitive manifestation of the effective combined development of the aviation industry and the circular economy, which involves the conversion of passenger aircraft to cargo and aircraft dismantling. In the new era, it shows the characteristics of intensive development of technology and capital. According to the operation scale of China’s aircraft in recent years, with the improvement of scientific research and technology, the number of aircraft fleets is also growing continuously, and the corresponding number of retired aircraft is also increasing every year, which proves that the development of China’s retired aircraft reuse industry has a very broad prospect. Therefore, on the basis of understanding the current global trend of aircraft life-cycle training and utilization, this paper calculates the FA model based on the potential output value of the retired aircraft recycling industry based on the FA-SD model, analyzes the empirical analysis and prediction of the evaluation model of the retired aircraft recycling potential, and identifies the effective measures for future development.

Abstract In this paper, the possibilities of improving the traction and economic characteristics of a by-pass turbojet engine of a high-speed passenger aircraft due to minimal modifications of the high-pressure compressor. A thermodynamic model of the investigated engine of a new design in a three-dimensional layout was formed using an automated multicriteria optimization process. A computational assessment of the change in the characteristics of compressor modifications is carried out based on a numerical model of gas dynamics.

Abstract The main objective of this work was testing a possibility of application of commercial videogrammetric system Vic-3D for measuring position and deformation of the aircraft model and its elements in an industrial the TsAGI transonic wind tunnel T-128. The object of research was a model of passenger aircraft with a wingspan of 2010 mm, fixed on the rear sting. The Vic-3D system used for measuring the position and deformation of the aircraft model was applied for the runs with and without flow at the pitch angles range from − 3 to +12 degrees. Model was tested in wind tunnel up to Mach number M = 0.853. An algorithm of working with the Vic-3D system was described in the article, some specifics of obtained results were underlined. An additional program to derive bend and twist deformations of a wing was developed. Results of an experiment were given, errors and inaccuracy were analyzed. Recommendations for using the system Vic-3D in an aerodynamic experiment were given.

This paper riset aims to examine and analyze the legal rule regarding airlines for passenger aircraft in Indonesia is Law No. 8 of 1999 concerning Consumer Protection, Law no. 1 of 2009 concerning Aviation and Regulation of the Minister of Transportation No. 89 of 2015 concerning Handling Delays in Scheduled Commercial Air Transport Business Entities in Indonesia and Regulation of the Minister of Transportation Number 92 of 2011 amending the Regulation of the Minister of Transportation No. 77 of 2011 concerning the Responsibility of Air Transport Carriers. The factors causing the delay in departure at Kualanamu Deli Serdang International Airport are one of the factors of weather, and technical problems on aircraft but which are more often caused by weather, especially Kuala Lumpur is the hub airport (collecting airport) of several small airports where the weather can change at any time -Time and it is a thing that often happens in Kuala Lumpur. The responsibility of domestic airlines to aircraft passengers who experience delays in departure at Kualanamu Deli Serdang International Airport is to provide compensation and compensation in the form of soft drinks, snacks and heavy meals as well as compensation, depending on the type of delay according to the category, namely: Category 1, 30 to 60 minutes delay, Category 2, 61 to 120 minutes delay, Category 3, 121 to 180 minutes delay, Category 4, 181 to 240 minutes delay, Category 5, more than 240 minutes delay, Category 6, namely flight cancellations, then the airline is obliged to divert to the next flight or refund all ticket costs.

AbstractAir Canada managed to have a passenger aircraft run out of fuel in mid-air due to confusion about metric units (Stephenson in Mars climate orbiter mishap investigation board phase I report, NASA, 1999), and NASA lost an entire spacecraft due to a misunderstanding amongst engineers about the units used in the propulsion system design (Witkin in Jet’s fuel ran out after metric conversion errors, The New York Times, 1983). Measurements only make sense if the units are correct and well-defined. A unit of measurement is a definite magnitude of a quantity, defined by convention or law. Any other quantity of that kind can then be expressed as a multiple or submultiple of the unit of measurement. The Egyptians used the Farao as definite magnitude, while many years later, the french revolutionists introduced the earth as a reference and laid the foundations for the modern decimal system. Since recently, we have a truly universal and stable system that uses physics’s natural constants and laws to define the base units of measurement. This paper explains how this new concept works and how it is implemented in practice.

The research is designed to explore wide-body aircraft that are more suitable in 2035-2040. The innovative design of the wide-body aircraft adopts the form of the main passenger compartment and wing separation, the passenger compartment in the form of a single engine car through the rail transit and transfer car travel together. The transfer car delivers the two engine cars in turn to the aircraft, which is tightly connected to the rail structure by mechanical claws. Engine cars can split up at the transfer station, thus assisting in the diversion of passengers. The interior of the engine car has been optimized. A visual mask can be used for isolation has been designed for the seats. And a device is designed to lighten passengers’ legs to alleviate “economy class syndrome.” The corresponding data analysis used the mobile edge computing technology.
