Improvement of flow quality in the test section of wind-tunnel with two configurations of screens is evaluated, using two methods - by the measurement of aerodynamic drag of sphere and by the hot-wire CTA measurement of turbulent fluctuations. Only configuration with the screen in settling chamber improves the quality of the flow.

In this article is proposed mobility model for UAV and the evaluation tool for groups detection during the movement of UAV. Mobility model assumes the existence of UAV devices with defined missions, a control group of UAV and ground control station in the network. Simulation of the movement in software Matlab was created and shows the continuance of UAV missions during the movement. Information about positions was used for community detection by the evaluation tool. Modularity quality was a pointer for evaluation of quality for given found communities in the network. This type of evaluation method can be used for each movement, where is needed to detect some relations among nodes. Some other evaluation methods for community detection is described in this article.

This paper describes the new concept for commercial aviation transport using the automatic formation flight issues. The largest part of the work is dedicated to new airport concepts for formation flight operations. The idea was extracted from the operations that are performed commonly on large airports with close spaced parallel runways in North America. These operations are called paired approaches where one airplane follows the other on final approach. Main goals of this paper were to bring concepts that would be able to increase the airport runway system capacity, an increase in airspace capacity, to reduce fuel consumption and to create an idea on how the future air transport could look like. We have found out that some of designed concepts and procedures could be used, however, they will require more researches and development in aerodynamics and systems.

The article presents an estimate of human factor reliability in aircraft operation. The analysis of human factor reliability to identify possible human errors and their impact is the systematic assessment of factors affecting workers. The analysis includes the identification of important sites affected by various errors caused by high noise burden. The impact of noise on humans, especially in terms of the upper decibel scale or the long-term exposure of the decibel scale, leads to body strain and human error during work. The reliability of the human factor in aircraft operation is estimated by the TESEO method.

A small low-cost thermal vacuum chamber was designed, built and operated. The thermal cycling was done using inner shroud, designed to be used either as a pure cold-wall for radiative cooling or as a thermal contact plate. Computer controlled liquid nitrogen partial flooding system was adopted for cooling and hot air flow was used for heating of the shroud. The thermal vacuum chamber was used for validation of stability of properties of the primer BR 127 outside previously certified temperature range. The tape test (peel-off) of adhesion according to ASTM D3359 09 was done on the primer before and after the thermal-vacuum cycling. The tested primer stood the test without discernible changes of the adhesion properties.

The use of information technology at the airport facilitates the management of all processes and ensures the highest degree of security. In addition to these information systems, airports may also use information systems that allow pre-test the impact of the expected changes in the activities before their implementation in full operation thereby saving considerable costs if the expected change is inappropriate. This is done by modeling and simulation programs that allow you to create and view any reality and see how the system behaves when the input data is entered. This allows airports to find optimal solutions to optimize airport processes. The article discusses such information technologies to support modeling and simulation of airport with the support of 3D visualization of simulation results. The authors examine the available simulation tools and compare them on the basis of available functions useful for modeling and simulating airport processes. And by comparing them, they present a possible optimal information solution. Next, they explore the possibilities of deployment and present a solution for using such an information system for modeling and simulation of the passengers' handling process and displaying the simulation process in a real 3D model of the terminal at the airport in Košice.

The aim of the study was to make a 3D model of a Catholic Church in Székesfehérvár (Alba Regia) by using UAV indoor. This paper presents the process of the UAV photographing, modelling and evaluation of the results. The appropriateness of the steps is also presented. The chosen Church called the ‘Great Patroness of Hungary’ is located out of the downtown and will be rebuilt in the near future thus the survey and modelling can also be considered as a historical memory conservation.

In the paper we analyze the possibilities of creating a communication network for UAV. We assume that UAVs will work together on the basis of relative navigation (RelNav) principles using aeronautical communications systems. We explore the possibilities of using digital data communication systems to create a UAV communications network. We put emphasis on fast, safe and efficient communication. Leading manufacturers of radio communications stations include Rhode & Schwarz (Germany), Honeywell (USA), Rockwell Collins (USA). We describe new communication systems and devices that would be useful for creating a UAV communications network.

This paper describes the basic concepts for determining the cosmic objects position and motion according to the Kepler's Laws and Newton's law of Universal Gravitation. In addition, the paper also includes an algorithm to compute the (miniature) satellites orbit. The algorithm input data was received from two-line elements (TLE) record. One of the program outputs is the computation of the skCUBE miniature satellite orbit. Following the authors' research, this paper also contains a brief overview of the skCUBE development and its evolution. The MATLAB Live Editor was used for program implementation of the algorithm.
