“…Integration of the rapid prototyping environment and X-Plane software A simulator for the first test stage was built based on the team's experience gained in research and development presented in publications (Rzucidlo, 2013;Rydlo et al, 2013;Chudy and Rzucidlo, 2011;Chudy et al, 2012;Chudy et al, 2010;Grzybowski et al, 2012). The X-Plane software is used in this solution for modeling the external environment, atmospheric phenomena and intruder objects.…”

Purpose The purpose of this paper is to describe simulation research carried out for the needs of multi-sensor anti-collision system for light aircraft and unmanned aerial vehicles. Design/methodology/approach This paper presents an analysis related to the practical possibilities of detecting intruders in the air space with the use of optoelectronic sensors. The theoretical part determines the influence of the angle of view, distance from the intruder and the resolution of the camera on the ability to detect objects with different linear dimensions. It has been assumed that the detection will be effective for objects represented by at least four pixels (arranged in a line) on the sensor matrix. In the main part devoted to simulation studies, the theoretical data was compared to the obtained intruders’ images. The verified simulation environment was then applied to the image processing algorithms developed for the anti-collision system. Findings A simulation environment was obtained enabling reliable tests of the anti-collision system using optoelectronic sensors. Practical implications The integration of unmanned aircraft operations in civil airspace is a serious problem on a global scale. Equipping aircraft with autonomous anti-collision systems can help solve key problems. The use of simulation techniques in the process of testing anti-collision systems allows the implementation of test scenarios that may be burdened with too much risk in real flights. Social implications This paper aims for possible improvement of safety in light-sport aviation. Originality/value This paper conducts verification of classic flight simulator software suitability for carrying out anti-collision systems tests and development of a flight simulator platform dedicated to such tests.

“…Moreover, flight test costs are increased by the necessity of complex processing and interpretation of collected data, as well as limitations driven by regulations (Szewczyk et al , 2017; Rzucidlo et al , 2016). Bearing this in mind and capitalizing on experience obtained during previous in-flight tests, a distributed measurement system dedicated for UL and RPAS aircraft classes has been designed (Kopecki et al , 2013; Rydlo et al , 2013; Rzucidlo, 2013; Kopecki and Rzucidlo, 2014). The following high-level requirements for the system have been considered: easy integration on the board of the aircraft to reduce the effort required in the flight tests preparation phase; a modular structure to provide flexibility and adoptability dependent on flight tests type and customer needs; a single lightweight module, to avoid interfering with the center of gravity of the aircraft in a significant way; low power consumption with an independent power supply not requiring alteration of the aircraft electrical installation; and reduction of data processing time by providing dedicated software capable of interpretation tasks such as measuring correlations between measured variables. …”

Purpose This paper aims to describe the idea behind and design of a miniaturized distributed measurement system based on a controller area network (CAN) data bus. Design/methodology/approach The intention of the designers was to build a light and modular measurement system which can be used in remotely piloted aircraft systems and ultra-light aircraft during flight tests, as well as normal operation. The structure of this distributed measurement system is based on a CAN data bus. The CAN aerospace standard has been applied to the software as well as the hardware comprising this system. PRP-W2 software designed for PCs is an additional component of the proposed measurement system. This software supports data acquisition from a recorder unit and allows for preliminary data analysis, as well as data conversion and presentation. Findings The system, complete with a high-speed data recorder, was successfully installed on board of an MP-02 Czajka aircraft. A research experiment using the system and oriented on airframe high frequency vibration analysis is presented in the final part of this paper. Research limitations/implications This measurement system allows analysis of high-frequency vibrations occurring at selected points of the aircraft. A data set is recorded by three-axis accelerometers and gyroscopes at frequencies up to 1 kHz. Practical implications The use of a miniature and lightweight modular measurement system will, in many cases, be faster and less expensive than full-scale measurement and data acquisition systems, which often require a lengthy assembly process. The implementation of this class of lightweight flight test systems has many advantages, in particular to the operation of small aircraft. Such solutions are likely to become increasingly common in unmanned aerial vehicles and in other light aircraft in the future. Originality/value The adaptation of a distributed measuring system with a high frequency of measurements for purposes of small and miniature aircraft.

“…Numerous research centers conduct research on aircraft flight control systems. Scientists focus, for example, on the synthesis of various control laws (Braun et al ., 2014; Chudý et al ., 2009; Hendzel et al ., 2013; Mystkowski, 2013; Rogalski and Wielgat, 2010; Zhang and Jiang, 2008) and navigation algorithms (Eitner and Holzapfel, 2013; Gosiewski and Kulesza, 2013a; Szpunar and Rzucidlo, 2012); they describe hardware structure (Stojcsics and Molnár, 2012; Gosiewski and Kulesza, 2013b; Rydlo et al ., 2013), problems connected with the UAV ground station (Fuchs et al ., 2014) or problems of the system’s reliability (Dołęga, 2011; Dołęga and Rzucidło, 2010; Dołęga and Rogalski, 2008; Krawczyk, 2013). In hardware design for research purposes, it is advisable to use a system based on the digital bus structure, for example, Controlled Area Network (CAN).…”

Purpose The purpose of this paper is to present the topic of control computers diagnostics. They are part of an unmanned aerial vehicle (UAV) control system implemented in a modified version of MP-2 Czajka aircraft. Design/methodology/approach The algorithms were designed as a basic version of the diagnostic system. The system is open and will be developed. Findings First results show that the diagnostic system works properly. The system is easy for implementation and burdens the control computers only insignificantly. Research limitations/implications The system presented can detect only computers out of work. In its present version, it cannot detect such errors as improper calculations of control signals. After first in-flight testing, the system will be further developed. Practical implications The diagnostic system is implemented in an UAV technology demonstrator. Originality/value The designed system is the part of an UAV control system, designed for ground observation. Such technology demonstrator and flying laboratory enable different type of research in the area of aviation.
