![]() ![]() , using very simple computing techniques, properly predicted the basic structure of rotating detonation in a rocket engine, but experimental research carried out at that time was not successful, so the study of application of the CRD for propulsion was interrupted for a long time. Later, attempts of developing a continuously rotating detonation (CRD) for propulsion systems were undertaken also at the University of Michigan. Detailed research on spin detonation was also carried out at the University of Michigan. Meanwhile, at the Novosibirsk Institute of Hydromechanics the so-called stationary spin detonation was successively achieved by Voitsekhovskii and his coworkers. At the time, the idea of the application of a standing detonation for propulsion systems was examined by many authors for both ramjet and rocket engines. analyzed the possibility of the application of a rotating detonation wave to improve the propulsion efficiency of rocket propulsion. Also, at the same university Adamson et al. proposed and built the first pulsed detonation engine, which utilizes the detonation of a hydrogen–air mixture to produce propulsion impulse. However, the first idea of a possible application of detonation to the propulsion system comes from the University of Michigan where Nicholls et al. The possibility of improving the thermodynamic cycle by application of detonative combustion instead of deflagration was first proposed by Zeldovich, but he also pointed out difficulties in controlling such a very highly energetic and ultra-high-speed process to engine application. In the paper, a special emphasis is given to international cooperation in this area with partners from many countries engaged in the development of the pressure gain combustion to propulsion systems. In the Institute of Aviation in Warsaw, research on the application of the CRD to turbine engines as well as rocket, ramjet, and combined cycle engines was carried out. A research directed to measure and calculate flow parameters as well as to analyze the use of liquid fuels was conducted. These activities promoted international cooperation and stimulated RDE development not only in Poland but also in other countries. One of the first achievements was the demonstration of performance of the rocket engine with an aerospike nozzle utilizing continuously rotating detonation (CRD), and research was directed into development of a small turbofan engine utilizing such a combustion regime. Then, an intensive basic and applied research was started at the Institute of Heat Engineering of the Warsaw University of Technology. ![]() Initial studies conducted in cooperation with Japanese partners lead to development of a joint patent on RDE. ![]() Night bus from Port Lotniczy Warszawa-Okęcie to Wrocław, Dworzec AutobusowyĪve.A very short survey of research conducted in Poland on the development of the rotating detonation engine (RDE) is presented. ![]() Duration 4h 15m Frequency Every 2 hours Estimated price 1 100 ₴ - 1 600 ₴ Website Book at Phone +49 30 300 137 300 Email Website īus from Warszawa, Dworzec Zachodni to Wrocław, Dworzec AutobusowyĪve.
