The YF-20 is a Chinese liquid-fuel rocket engine burning N 2 O 4 and UDMH in a gas generator cycle. It is a basic engine which when mounted in a four engine module forms the YF-21 . The high altitude variation is known as the YF-22 is normally paired with the YF-23 vernier to form the YF-24 propulsion module for second stages.
The YF-215 engine has been designed to power the first stage of the Long March 9 rocket, with 26 of these engines in the first stage. [1] A successful ignition test of the pre-combustion chamber and gas generator of the engine was conducted on 12 May 2023.
Liquid rocket engines have tankage and pipes to store and transfer propellant, an injector system and one or more combustion chambers with associated nozzles.. Typical liquid propellants have densities roughly similar to water, approximately 0.7 to 1.4 g/cm 3 (0.025 to 0.051 lb/cu in).
In the case of solid rocket motors, the fuel and oxidizer are combined when the motor is cast. Propellant combustion occurs inside the motor casing, which must contain the pressures developed. Solid rockets typically have higher thrust, less specific impulse , shorter burn times, and a higher mass than liquid rockets, and additionally cannot be ...
