Item Sustainable aviation fuel from the perspective of long-term sustainability and development(University of Žilina, 2022) Šajbanová, Kristína; Janovec, Michal; Zachar Kuchtová, JanaThe aim of the article is to create a SWOT analysis of the position of sustainable aviation fuels (SAF) as an innovative available product on the aviation fuel market and to evaluate its development and application in the coming years. The motivation for the analysis and subsequent creation of this work is the fact that the topic of sustainable aviation fuels is currently extremely actual and also relevant for the future of air transport, as well as the future of the ecosystem from the point of view of reducing the emission load caused by the emissions of aircraft engines, which have a non-negligible share of the ecological load our planet. Because the combustion process in aircraft engines is the main factor in the creation of emissions, alternative aviation fuels from sustainable sources have been developed in order to reduce them. Thanks to the analysis of the goals of the influential aviation manufacturers, we found that the attention paid to the implementation of sustainable fuel is currently and will be given increased attention in the future. Achieving this goal will be made possible through technological advances and governance adjustments in many companies affecting aviation, from aircraft and fuel manufacturers to institutions dealing with administrative matters affecting aviation.Item Požiadavky na harmonizáciu údržby ultraľahkých lietadiel(University of Zilina, 2022) Škultéty, Filip; Čerňan, Jozef; Janovec, Michal; Chodelka, FrederikThe exact definition of an Ultralight Aircraft is still very diverse, especially in the European region. Internationally, there are various Ultralight Aircraft (UL) classes with nationally varying certification regulations. Accordingly, Ultralight Aircraft is used colloquially ore or less comprehensively for Very Light Aircraft or Light-Sport Aircraft. However, they are subject to much stricter certification nd maintenance regulations. This paper aims to compare the current legal situation in the European Union countries, extract the best practices, and propose how a new “AMC & GM” should define the laws and regulations to create the best possible vironment for UL airworthiness. This paper is written based on information and directions published on the websites of the esponsible uthorities of the respective countries, as well as communication with these authorities and first-hand knowledge obtained by conducting numerous interviews with people in the field of UL maintenance. The results indicate how different each country egulates the maintenance and continuing airworthiness of ULs and how important a harmonised regulation would be. It is specially important to have clarity as with larger aircraft and thus also to prevent numerous accidents and hazardous situations in the future.Item Návrh zdokonalenia ovládacích prvkov simulátora Zlín(University of Zilina, 2022) Janovec, Michal; Materna, Matúš; Pecho, PavolThis article deals with possible improvements and improvements of the flight simulator Zlín, which is located at the Air Transport Department of the University of Žilina. The construction of the simulator and the basic control and display units of the simulator ere made in the previous period. For the most realistic feeling of flight, it is necessary to constantly innovate and improve the simulator. The created technical improvements of the simulator control panel, the control mechanism of the lateral and ongitudinal tilt, the balance control and the flaps control to this improvement of the simulator. In the article, these performed improvements of the simulator are described in detail. According to these procedures, the proposed improvements were subsequently practically performed on a simulator.Item Conversion of passenger aircraft to cargo versions(University of Zilina, 2022) Mlynarčík, Martin; Janovec, MichalIn this presented paper on the topic of conversion of passenger aircrafts to cargo versions, the use of this transformation in the modern history of aviation is analyzed and the current situation is analyzed. For a better introduction to the issue, the introductory part defines the fundamental terms and explains the conversion itself and its various stages. The paper also discusses the companies that provide services for the actual conversion of passenger aircraft and the location where this process takes place. The paper is further supplemented by individual types of aircraft, which are divided according to global manufacturers such as the American Boeing and its European competitor Airbus. The main goal of this paper is to bring closer and clarify this process, which has gained momentum in recent years and has great potential for the future. This paper is very significant in case of COVID-19 pandemic and its huge influence on general aviation when there is enormous demand of conversion passenger aircrafts to cargo versions. The most common causes of conversion, advantages and disadvantages are also included. The conversion process itself is described in more detail and the paper focuses on the various technical phases of the aircraft conversion itself.Item Possibilities of using 3D printing technology in production of aircraft components(University of Zilina, 2021) Šajbanová, Kristína; Čerňan, Jozef; Janovec, MichalThe article provides the reader with a brief overview of the technology of industrial 3D printing used in the manufacturing process of aerospace technology. It includes analyses of the position of 3D printing in the aerospace industry and the forecast of its future development based on the marketing analysis of strengths / weaknesses, opportunities and threats. Many airlines and AMOs (Approved Maintenance Organizations) rely on externally supplied spare parts delivered over long distances. The whole process is expensive and time consuming and means a lost profit for the company. The performed SWOT analysis can therefore ultimately help the AMO manager to re-evaluate their production process in the light of the current innovative and progressive technology of industrial 3D printing.The aim of this work is to point out the existence of innovative 3D printing technology in aerospace production and to emphasize its preferences compared to conventional manufacturing techniques and procedures, thus providing a final perspective on the future of the 3D printing industry and its long-term sustainabilityItem Prototyp simulátora letového environmentálneho laboratória Evirolab(University of Žilina, 2021) Janovec, Michal; Materna, Matúš; Pecho, Pavol; Kandera, Branislav; Radosa, FilipThe aim of this paper is to create a solid structural platform for the placement of computer equipment and other computer accessories to create a flight simulator from scratch. The simulator will be designed to help pilots in training get accustomed to basic flight procedures and the behavior of aircraft control surfaces during flight. Practical part deals with the design of a simulator inspired by the airplane Zlín Z 242 L, the selection of suitable material and technology to produce this simulator and the measurement of most important dimensions required for the making process. Obtained dimensions will be used to model the structure in a three-dimensional plane with the help of computer aided software, in order to create blueprints of our simulator structure. Said blueprints will be later used to cut building materials to required length and to assemble the construction frame. Last pages are dedicated to seating all required computer software directly on the frame in the correct manner.Item Rozbor bezpečnosti letov UAV a konspekt aktuálnych legislatívnych požiadaviek(University of Žilina, 2021) Škultéty, Filip; Kandera, Branislav; Janovec, MichalDespite the recent legislation, which has been formed in the last five years to its current form, the safety for the UAV operation is borne by the pilot, as he/she is the one who is responsible for the direction of UAV movement thus for any collision. For this reason, it is necessary to increase the safety of UAV operations outside the duties and competencies of the pilot at a distance, for example, through anti-collision systems and air traffic management systems. This article was initially focused on analysing aviation events in Slovakia associated with the operation of the UAV. Another factor that significantly affects the operation of UAVs to a large extent is the legislation itself. A special part was devoted to the legislation in terms of airspace determination, procedures and rules of operation of the UAV. From a legislative point of view, it is currently an important aspect to define the correct and reasonable level between the restrictions in order to increase the safety of operation only on an indispensable scale, not to be very restrictive to operators.Item Mass and performance estimation of hydrogen and battery powered transport aircraft concepts(University of Zilina, 2021) Babčan, Viktor; Janovec, MichalThis article introduces the scope and activities linked to an end of studies project.
