CRYOGENIC ROCKET ENGINE
INTRODUCTION
What is Cryogenics?
Cryogenic fuels can be used as rocket engine fuel.
Cryogenic Engines are rocket motors.
HISTORY
Space travel was mainly developed by the Russians and the Americans. Russian’s were the first to reach into the space.
Solid-fuel rocket engines were the first engines created by man.
All the current Rockets run on Liquid-propellant rockets.
The first operational cryogenic rocket engine RL10 rocket engine.
SPACE PROPULSION SYSTEM
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites.
Rocket Engines
Interplanetary vehicles mostly use chemical rockets as well.
Cryogenic Engine is also in use.
Classification Of Space Propulsion System
CRYOGENIC FUELSCryogenic propellant - the fuel and the oxidizer
super cooled gases -temperature lower than the freezing point.
To store them is difficult task
cooling and compressing them into liquids, we can vastly increase their density and make it possible to store them in large quantities in smaller tanks.
Nitrogen, hydrogen, oxygen, helium argon, neon, etc,
Liquid oxygen being the oxidizer and liquid hydrogen being the fuel.
Liquid oxygen boils at 297oF and liquid hydrogen boils at 423oF.
Components Of Cryogenic Rocket Engine
Thrust chamber or combustion chamber Igniter Fuel injector Fuel turbo-pumps Valves Regulators Fuel tanks Rocket engine Nozzle
Among them, the combustion chamber & the nozzle are the
main components of the rocket engine.
