Purpose The purpose of this paper is to present the idea of automatic flight control algorithms capable of performing an Immelmann turn manoeuvre automatically. This is a case of a manoeuvre far removed from so-called standard flight. The character of this manoeuvre and the range of changes in the aircraft flight parameters restrict the application of standard control algorithms. Furthermore, the possibility of acquiring full and detailed information about the aircraft’s flight parameters is limited in such cases. This paper seeks to analyse an alternative solution that can be applied in some specific cases. Design/methodology/approach This paper uses theoretical discussion and breakdowns to create the basics for development of structures of control algorithms. A simplified analytical approach was applied to tune regulators and the results of the research were verified in a series of software-in-the loop computer simulations. Findings The structure of the control system enabling aerobatic flight (with the Immelmann turn as the selected example) was identified and the method for tuning the regulators is also presented. Practical implications It could serve as a foundation for autopilots working in non-conventional flight states and aircraft automatic recovery systems. Originality/value This paper presents the author’s original approach to aircraft automatic control when high control precision is not the priority and not all flight parameters can be precisely measured.

“…A real-time simulation campaign was conducted according to the Software-In-the Loop (SIL) methodology (Dolega and Rogalski, 2004; Rzucidlo et al , 2013) to verify assumptions made in the design of the algorithms, simplifications applied for calculations as well as the overall approach to the discussed problem. Simulated flight disclosed the operation of developed algorithms, their impact on the aircraft model’s behavior and interaction with it.…”

Purpose The paper aims to present an idea of automatic control algorithms dedicated to both small manned and unmanned aircraft, capable to perform spin maneuver automatically. This is a case of maneuver far away from so-called standard flight. The character of this maneuver and the range of aircraft flight parameters changes restrict application of standard control algorithms. Possibility of acquisition full information about aircraft flight parameters is limited as well in such cases. This paper analyses an alternative solution that can be applied in some specific cases. Design/methodology/approach The paper uses theoretical discussion and breakdowns to create basics for development of structures of control algorithms. Simplified analytical approach was applied to tune regulators. Results of research were verified in series of software-in-the loop, computer simulations. Findings The structure of the control system enabling aerobatic flight (spin flight as example selected) was found and the method how to tune regulators was presented as well. Practical implications It could be a fundament for autopilots working in non-conventional flight states and aircraft automatic recovery systems. Originality/value The paper presents author’s original approach to aircraft automatic control when high control precision is not the priority, and not all flight parameters can be precisely measured.

“…The control algorithms presented in the previous section of this paper were tested in several ways. Tests started from computer simulations with the use of a specialized laboratory stand (Dolega et al 2004). Simulations were performed in accordance with hardware-in-the-loop-simulation technology.…”

The research team from Control and Avionics Department of Rzeszow University of Technology (RUT) has been working on control systems for many types of flying objects for years. Experiences the team has had during their activity have helped create the control algorithms for a medium‐size flying target (MSFT). Researchers from RUT, together with the small aviation company EUROTECH, have been working on a flying target for artillery. This paper gives a generic view of the system, including airborne and on‐ground parts. But this paper mainly presents the control system that is mounted on the MSFT. The paper describes the generic conception of the control system of the flying target, including control laws used in the control system of the MSFT. Results of simulations and real flight data are also presented.
