It is a challenging part of aerodynamics that defines a comprehensive approach to using traditional methods and modern techniques to obtain relevant data. The most complicated task for the aerodynamics and flight dynamics is definition, computation and quantification of the aerodynamic description of an object. This paper presents how to determine the aerodynamic load on a gyrocopter and defines the effect on its stability and control. The first step to solution is to develop simpler approximate aerodynamic model - a model that can be used in analysis of aerodynamic load and can represent the aerodynamic properties of the gyrocopter with an acceptable degree of accuracy. Control and stability are very important parts of aircraft characteristics and therefore those characteristics were analyzed in simulation. Finally, the aerodynamic dat...

However, UAVs belong to a class of nonlinear systems that are inherently difficult to control. In this study we devised a mathematical model for a PID (proportional integral derivative) control system, designed to control a quadrotor UAV so that it follows a predefined trajectory. After first describing quadrotor flight dynamics, we present the control model adopted in our system (developed in MATLAB Simulink). We then present simulated results for the use of the control system to move a quadrotor UAV to desired locations and along desired trajectories. Positive results of these simulation support the conclusion that a quadrotor UAV spatial orientation control system based on this model will successfully fulfil its task also in real conditions.

The main benefit of these technologies is the possibility to monitor, transfer, store, and analyze huge datasets. Based on analysis outputs, there is a possibility to improve current preventive maintenance processes and implement predictive maintenance processes. These solutions lower the downtime, save manpower, and extend the components’ lifetime; thus, the maximum effectivity and safety is achieved. The article deals with the possible implementation of an unmanned aerial vehicle (UAV) with an infrared camera and Radio Frequency Identification (RFID) as two of the smart hangar technologies for airframe condition monitoring. The presented implementations of smart technologies follow up the specific results of a case study focused on trainer aircraft failure monitoring and its impact on mainten...

Following the evolutionary path, incorporating advanced automated and first autonomy systems, the applications involved are becoming increasingly data- oriented. The need for progressive data analytics, massive adoption and operation of IoT devices, delivering advanced monitoring and machine learning opportunities, building the core structure for artificial intelligence, will put a significant pressure on data communication and connectivity itself. In the near future, the problems may especially arise in datalink used in civil aviation. This research paper briefly studies the contemporary systems used for datalink, determines dominant aspects of Aviation 4.0 and their overall impact on the performance requirements of the data communications network, and proposes the possible solution to the ...

Huge recent technological advancements have led the whole aeronautical industry into the new evolutionary era called Aviation 4.0. The goal of Aviation 4.0 is the creation of cyber-physical system, following the path from advanced automation, to very first autonomy systems efficiently assisting human. This system involves multiple direct data related applications and devices, including AI analytics, massive use of IoT devices, machine learning capabilities, or advanced monitoring. Due to needed enormous flow of data, current connectivity solutions are becoming insufficient for the future use cases. Near future connectivity problems may become very apparent in datalink. With exponentially increasing amount of data needed by the future aircraft systems, higher datalink communication capacity and better performance of datalink subnetwork are required to meet the higher performance standards and le...

V súvislosti s narastajúcou potrebou skvalitňovania a zefektívňovania procesu vzdelávania, je potrebné riešiť medzinárodnú spoluprácu pri vzdelávaní odborníkov v leteckej doprave. Odpoveďou na tento problém bolo vytvorenie znalostnej aliancie v rámci projektov ERASMUS+, ktorá analyzuje globálny trh povolaní a kvalifikácií v leteckej doprave. Cieľom projektu bolo špecifikovať zoznam súčasných povolaní, ale aj budúcich povolaní v nadväznosti na analýzu kvalifikácií v odvetví leteckej dopravy. Na základe týchto výstupov projektu bol vytvorený nový študijný program ako aj upravené programy ďalšieho vzdelávania v letectve. Príspevok poukazuje na výstupy a prínosy takejto spolupráce.

It discusses the problem of GNSS signal interference and interference identification on a practical example of a small regional airport in Zilina, located close to the highway, through research aimed at its identification, a proposal for the location of a monitoring station and subsequent practical verification. The paper seeks to analyse and provide recommendations for enhancing safety and reliability in GNSS approaches. Given the need to develop the air transport, it is important to ensure the safety and continuity of service provision at small regional airports. The GNSS approach at airports with insufficiently equipped navigation infrastructure seems to be one of the most suitable. Introduction of the GNSS interference monitoring in the final instrument approach phase would increase the safety and reliability of the flight.

Air transport has been connecting the continents with each other. Increased the volume of trade and made it easier to trade with the HUB concept. Airline companies are in the advertising competition while the safety of the flight is at the forefront. Each is more aimed at flying to the region and more often operating. At this point, the limits of competition have been so difficult that our lives have entered different levels of service, including low-cost and traditional. Low-cost airline companies aimed to reduce their costs by cutting some services in the airplane. such as the right to baggage being offered as a separate entitlement other than the ticket price. this service does not mean to cut off safety precautions regularly. Airlines continue to keep all security systems as strong as ever. The purpose of these discontinuit...

Throughout the economic and commercial development and with disappearance of boundaries between countries is rapidly changing air transport. The transportation and logistics investments and competition between companies and states rapidly increased. Thus, transportation modes developed and changed rapidly as a natural response to development itself. In the paper, we will practice the comparison of two major companies of European Air Freight: Turkish Airlines and Lufthansa.
