  • Environmental Control System Analysis to Investigate The Indoor Air Quality of an Aircraft   Order a copy of this article
    by Cem Tahsin Yucer, Hakan Keskin 
    Abstract: Environmental control system (ECS) in aircraft provide comfortable environment for people and goods. The temperature, pressure and humidity are vital properties of indoor air in aircraft. In this study, the systems used for conditioning the indoor air of the aircraft are considered. The hot and pressurised air that came from the compressor of the engine is transferred to the cabin by changing some of its characteristics. Thus, the indoor air quality is controlled. This study analyses the ECS in aircraft. Some of these systems are cabin air conditioning, pressurization, humidity control and temperature control. When investigating these systems, some important values were obtained for ensuring the comfort and safety in the aircraft. Fresh air renewal period, strength for the skin panel, humidity formed in the cabin and heating demand were found to be 443 s, 84.8 kN/m2, 0.6 g/kg and 106.2 kW, respectively.
    Keywords: Indoor air quality; aircraft environmental control systems; indoor air conditioning.

    by Chingiz Hajiyev, Burak Kamiloglu 
    Abstract: Inertial Navigation Systems (INSs) require some type of aiding and updating in the long term to remain valid. In many applications for purpose of INSs error compensation its integration by GPS is preferred. In this study the Kalman filter based loosely-coupled integrated INS/GPS is designed and investigated on the Boeing-747 Aircraft Model. The INS errors are modelled, estimated and compared with integrated navigation system errors which are position, velocity and attitude for each axis. The proposed integrated navigation system has high accuracy than stand-alone INS and it provides more reliable navigation information.

  • RESEARCH OF THE JET A-1 AIRCRAFT FUEL ELECTRIFICATION   Order a copy of this article
    by Igor Trofimov, Andrian Yavnyuk, Margaryta Radomska 
    Abstract: Abstract: The paper is devoted to the processes of aviation fuel JET A-1 electrification; it also presents the discussion of the research results in this area available from open resources. The purpose of this work was to study the phenomenon of hydrocarbon liquids' electrification and to substantiate the possibility of using static electricity to generate electric power with the separation of charges in dielectric liquids., The aviation fuel has been chosen as an object of research, since modern requirements to the refueling aircraft with high-performance pumps followed by the fine filtration are the stable source of static charges generation, which raises the need to combat them. Static charges were identified and measured with the standard techniques. The results of measurements show the dependence between the parameters of static charge density and the flow, flow rate, flow rate gradient and length of the pipeline. The level of the tank filling has been also accounted as a special index, measured in the model system. We have also developed the device and the method for obtaining high voltage power, which is based on the positive use of charges of the static electricity derived from the static charge converter, which is a standard application in all technological schemes of aviation fuel supply services of Ukrainian airports. The further research must cover the effect of fuels electrification on the change of their operational properties, with the subsequent possibility of fuels operational properties modification with the help of electrostatic fields.

  • METHODOLOGICAL PROPOSAL FOR THE SUPPLY CHAIN RISK MANAGEMENT WITHIN THE AERONAUTICAL SECTOR   Order a copy of this article
    by Miguel Suffo 
    Abstract: This works describes the agents involved in the supply chain of the aeronautical sector. These agents are in charge of receiving and processing truthful information that is subject to a series of risks. Within the paradigm of globalization of markets, the aeronautics industries must face the risks derived from the decentralization of their value processes. Even though this decentralization is mainly aimed at reducing costs, it also generates uncertainty due to the introduction of suppliers in developing markets. We propose a methodology that helps identify and classify these risks and allows selecting and sizing the most appropriate strategy to deal with them. The most frequent reactions developed by the companies to manage the risks are explained through a real case study of the aeronautical sector. Finally, in only six months, the application of the methodology to the real aeronautical case has allowed the risk management department to reduce them by 35%

  • The role of integration in achieving sustainable benefits from airline alliances   Order a copy of this article
    by Gamze Orhan, Deniz Taşcı 
    Abstract: Air transport is one of the industries where strategic alliances are most common. While alliance strategies by airlines are widespread, the performance and sustainability of alliances is currently in debate. However, the importance of the level of integration for the benefits from mergers and alliances in the literature is an important topic discussed. In this study, we relate the sustainability of alliances to the benefits gained from that cooperation and aimed to demonstrate the importance of the level of integration on the alliance benefits in the airline industry. To achieve this aim, after a comprehensive literature, we conducted a research on three global airline alliance members. The study comprises 26 international airlines who are members of one of global airline alliances Star, SkyTeam and Oneworld. The results suggest that there is a significant and positive relationship between level of integration of airlines to the global alliance and the alliance benefits gained from the alliance membership.

  • Robust planning the landing process of unmanned aerial vehicles   Order a copy of this article
    by Nguyen Dinh Dung, Joszef Rohacs 
    Abstract: Unmanned aerial vehicle (UAV) is a particular robotics type that has been studied by scientists in the world. Currently, the study of flying robots in complex environments is relatively well developed and has many achievements. However, the fact that the landing process of UAVs in complex or unknown environments is a significant challenge for scientists. In this paper, the problem that how to determine the desired landing orbit will be solved. The approach and landing process might be constructed from the straight lines and orbit curves. This study indicates that the UAV has four landing trajectories because the UAV can turn left or right to reach the left or right circle in the landing process. The methodology for calculating these landing trajectories will be shown in this paper, which is calculated based on solving aircraft equations of motion and analytical method. The desired landing orbit is the shortest route selected from these trajectories. This paper also shows the methodologies to determine the landing routes that the UAV can be landing in any direction or given direction. The simulation results utilizing MATLAB software show that the calculated landing orbit is the shortest.
    Keywords: unmanned aerial vehicle; landing trajectory; landing process; desired landing orbit.

  • Cultural and Political Attitudes Towards Paying to Support Airport Sustainability Projects   Order a copy of this article
    by Mattie Milner, Dylan Bush, Emily Anania, Taro Ito, Daniel Marte, Stephen Rice, Scott Winter 
    Abstract: The current research explores different factors affecting individuals support for airports implementing environmentally-friendly programs. Using social identity theory, the researchers manipulated participants identification with one of the two major political parties to explore the relationship between political affiliation and support for environmentally-friendly initiatives. Participants (recruited from the U.S. and India) were presented with a hypothetical scenario in which twelve different sustainable aviation projects would be implemented at their local airport. Implementation of these projects would include a $15 fee to their ticket price. Participants were then asked to indicate their support for the additional fee for each of the twelve programs. Results from this study indicate significant differences in acceptance of sustainable aviation programs based on a variety of political and cultural factors. In general, liberals/progressives and Indians were more willing to pay the additional fee, regardless of the type of program.
    Keywords: sustainable aviation; social identity theory; political affiliation; cultural attitudes; environmental concern; support for sustainable projects.
