A prototype RDE under test at the Marshall Space Flight Centre. A rotating detonation engine (RDE) uses a form of pressure gain combustion, where one or more detonations continuously travel around an annular channel. Computational simulations and experimental results have shown that the RDE has potential in transport and other applications.
Rotating detonation engine, a rocket engine that uses continuous detonation to provide thrust. Rotating disk electrode , a type of electrode used in electrochemistry Remote data entry , a process for the collection of data in electronic format
A rocket engine test facility is a location where rocket engines may be tested on the ground, under controlled conditions. A ground test program is generally required before the engine is certified for flight. Ground testing is very inexpensive in comparison to the cost of risking an entire mission or the lives of a flight crew.
On 26 July 2021 (UTC), Japan's space agency JAXA successfully tested a pulse detonation rocket engine in space on a S-520 sounding rocket flight. [9] The upper stage of the rocket used a rotating detonation engine (RDE) as the main engine and a S-shaped pulse detonating engine was used to de-spin the stage after the main engine burn. PDE ...
A shock-induced combustion ramjet engine (abbreviated as shcramjet; also called oblique detonation wave engine; also called standing oblique detonation ramjet (sodramjet); [1] or simply referred to as shock-ramjet engine) is a concept of air-breathing ramjet engine, proposed to be used for hypersonic and/or single-stage-to-orbit propulsion applications.
However, detonation waves may also be used for less destructive purposes, including deposition of coatings to a surface [25] or cleaning of equipment (e.g. slag removal [26]) and even explosively welding together metals that would otherwise fail to fuse. Pulse detonation engines use the detonation wave for aerospace propulsion. [27]
A rocket-powered aircraft or rocket plane is an aircraft that uses a rocket engine for propulsion, sometimes in addition to airbreathing jet engines.Rocket planes can achieve much higher speeds than similarly sized jet aircraft, but typically for at most a few minutes of powered operation, followed by a gliding flight.
An engine test stand is a facility used to develop, characterize and test engines. The facility, often offered as a product to automotive OEMs , allows engine operation in different operating regimes and offers measurement of several physical variables associated with the engine operation.
