The basic concept of an RDE is a detonation wave that travels around a circular channel (annulus). Fuel and oxidizer are injected into the channel, normally through small holes or slits. A detonation is initiated in the fuel/oxidizer mixture by some form of igniter. After the engine is started, the detonations are self-sustaining.
A pulse detonation engine (PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. [ 1 ] [ 2 ] The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next.
The Humphrey cycle is the thermodynamic cycle occurring detonation engines such as rotating detonation engines, the pulse detonation engines, and pulse compression detonation systems. It may be considered to be a modification of the Brayton cycle in which the constant-pressure heat addition process of the Brayton cycle is replaced by a constant ...
The CJ-2000 is a scaled-up version of the CJ-1000 HP spool and combustor core, with 10 compressor stages and two turbine stages. As of June 2018, the new 78,000 lbf (350 kN) engine destined for the COMAC C929 was expected to be demonstrated in 2023 and enter service in 2030.
The YF-130 is a Chinese rocket engine fueled by LOX and kerosene in an oxidizer-rich staged combustion cycle currently in development. It has been designed to reach around 500 tonnes of thrust and it will power the super heavy Long March 9 rocket.
Unintentional detonation when deflagration is desired is a problem in some devices. In Otto cycle, or gasoline engines it is called engine knocking or pinging, and it causes a loss of power. It can also cause excessive heating, and harsh mechanical shock that can result in eventual engine failure. [29]
Demand in China for the latest generation cards is so high that Chinese resellers are already advertising the chips bought outside the country for up to $5,700 on Chinese e-commerce platform Taobao.
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.
