“…Typically for detonation of fuel air mixtures pressure can be increased about 15 times, while detonation of fuels with gaseous oxygen can increase more than 30 times. Details of the detonative combustion of gaseous mixtures can be found in many publications [14][15][16][17]. Because combustion of the same mixture can result in very different parameters depending on the deflagrative or detonative mode, application of different modes of combustion to a propulsion system can also result in different performance of the propulsion system.…”

“…It was shown already in many publications that application of detonative combustion to engines can result in significant increase of engine efficiency. For example, if detonative combustion is applied to the turbojet engine, theoretical engine efficiency could be even increased more than 30% [14], but even if in reality this efficiency will be increased only by 10%, the fuel saving for one year will result in many billions of dollars, as well as significant reduction of CO 2 emission.…”

“…More information about such research could be also find on survey paper devoted to the PDE [10][11][12]. Only at the end of last century and the beginning of this one research on the possible application of the CRD to propulsion system was nearly simultaneously reinitiated in Russia, France, Poland and Japan then exponential interest on such system was significantly increased [13][14][15]. Since that time many initiatives were undertaken to better understand nature of detonative propulsion and to develop engines based on detonation.…”

In the paper short information about advantages of introduction of detonation combustion to propulsion systems is briefly discussed and then research conducted at the Łukasiewicz-Institute of Aviation on development of the rotating detonation engines (RDE) is presented. Special attention is focused on continuously rotating detonation (CRD), since it offers significant advantages over pulsed detonation (PD). Basic aspects of initiation and stability of the CRD are discussed. Examples of applications of the CRD to gas turbine and rocket engines are presented and a combine cycle engine utilizing CRD are also evaluated. The world's first rocket flight powered by liquid propellant detonation engine is also described.

“…In order to decrease the intensity of back-propagation waves, various valve schemes including aero-valve and mechanical valve affecting on back-propagation were studied. Because of the complex configuration, high aerodynamic resistance, as well as the potential strength and fatigue problems of mechanical valves, the aero-valve is believed to be the most promising solution [45][46][47][48]. With the reasonable inner channel design of the aero-valve, the compatibility between the compression component and the periodic and strong back-propagation waves, and the self-adaptive reactant supply can be realized.…”

Detonation is a promising combustion mode to improve engine performance, increase combustion efficiency, reduce emissions, and enhance thermal cycle efficiency. Over the last decade, significant progress has been made towards the applications of detonation mode in engines, such as standing detonation engine (SDE), Pulse detonation engine (PDE) and rotating detonation engine (RDE), and the understanding of the fundamental chemistry and physics processes in detonation engines via experimental and numerical studies. This article is to provide a comprehensive overview of the progress in the knowledge of rotating detonation engine from the different countries. New observations of injection, ignition, and geometry of combustor, pressure feedback, and combustion modes of RDE have been reported. These findings and advances have provided new opportunities in the development of rotating detonation for practical applications. Finally, we point out the current gaps in knowledge to indicate which areas future research should be directed at.

“…Lu et al 20 designed a mechanical rotary valve injection system for propane, oxygen and air in their development of a high frequency pulse detonation rocket facility, and the obtained maximum operating frequency was 20 Hz due to friction of the rotating system. Matsuoka et al 21 proposed a novel rotary valve system for PDRE and operating frequency achieved at 33.3 Hz. However, rotary valve was not their main study goal and gaseous fuels were used in their research.…”

Two types of rotary valve were designed and fabricated for single-tube pulse detonation rocket engines. According to their driving components, they were named as gear-driven and cam-driven rotary valve, respectively. Preliminary experimental investigations were carried out to test their feasibility for supply of the single-tube pulse detonation rocket engine. Based on the gear-driven rotary valve, the single-tube pulse detonation rocket engine operated at 10 Hz stably. When operating frequency was increased to 15 Hz, inconsecutive detonations happened which was due to signal output block in the encoder. It was found that optimal ignition timing needed to be adjusted to obtain stable operation in the gear-driven rotary-valved pulse detonation rocket engine. Discussion on this was conducted. Operations of the camdriven rotary-valved pulse detonation rocket engine were also performed. Fully developed and successive detonations at 40 Hz were successfully obtained although an explosion happened in initial tests. Experimental results showed that these two types of rotary valve were able to realize supply control of single-tube pulse detonation rocket engines effectively.
