Advancements in VDL and CPDLC: revolutionizing European aviation communication
(University of Žilina, 2023) Novák, Andrej; Kováčiková, Kristína
The paper is focused on the transformative impact of VDL and CPDLC on aviation safety, efficiency, and reliability. Tracing the historical evolution from radio systems to the adoption of VDL and its integration within Europe's unified airspace initiatives, this paper deals with key theories including VDL Mode 2, ACARS, Aeronautical Telecommunication Network, ADS-B, and CPDLC. Emphasizing interdisciplinary collaboration to tackle communication challenges, the paper spotlights CPDLC's evolution integrating AI, Machine Learning, cybersecurity protocols, and technological integrations like 5G and satellites. Human-Computer Interaction research underscores user-friendly CPDLC interface designs. Methodologies encompass operational analyses, communication protocols, avionics technologies, and usability testing. Aligning with the Single European Sky initiative, the integration of VDL and CPDLC anticipates emerging trends while addressing challenges like interoperability, training complexities, and cybersecurity vulnerabilities through proposed solutions. The paper offers a comprehensive understanding of advancements shaping the modern aviation communication landscape.
Long-range UAV hybrid petrol-electric powertrain
(University of Žilina, 2023) Uhlár, Erik; Pecho, Pavol
Along with increasing UAV both weight load and endurance requirements, there is a need to use alternative propulsion solutions, to satisfy the market as well as various customer applications. Although lithium polymer cells are yet well developed, they are still too heavy for long-endurance UAV missions. Hybrid petrol-electric powertrains are outstanding imitations of hybrid hydrogen-electric propulsion systems, which are currently under intensive development. Not only for their onboard power production and improved overall efficiency but also for simulating a weight load of a future hydrogen-electric system. Therefore, such a system is being tested and aimed to be used in fixed-wing UAVs for long-endurance missions. This paper describes the design and operation of a hybrid petrol-electric propulsion system and further operational optimization based on comprehensive ground testing.
Creation of a Z 43 aeroplane model for a flight simulator
(University of Žilina, 2023) Poláček, Jozef; Škultéty, Filip
This paper describes the process of developing a Zlin Z 43 aircraft for a flight simulator. Work on an aircraft simulation consists of multiple parts. The development of the flight model is the first and core part of the simulation. Work on this part consisted of an analysis of the X-Plane blade element theory-based flight model, sourcing of the data this model requires, flight testing and further editing of the data to match the known performance of the Zlín Z43. The aircraft systems are another core part of the simulation. A Mix of the simulator's default, customised and fully custom systems are used. The theory and process of creating, animating, and texturing a 3D model are described, too. Visual quality can also be important, especially for its use in virtual reality. The last part is about the user interface, user experience and how the various use cases shape their design for an aircraft simulation.
