2. INTRODUCTION
ï What is Cryogenics?
ï Cryogenic fuels can be used as rocket engine fuel.
ï Cryogenic Engines are rocket motors.
3. HISTORY
ï Space travel was mainly developed by the Russians and
the Americans. Russianâs were the first to reach into the
space.
ï Solid-fuel rocket engines were the first engines created by
man.
ï All the current Rockets run on Liquid-propellant rockets.
ï The first operational cryogenic rocket engine RL10 rocket
engine.
4. SPACE PROPULSION SYSTEM
ï Spacecraft propulsion is any method used
to accelerate spacecraft and artificial
satellites.
ï Rocket Engines
ï Interplanetary vehicles mostly use
chemical rockets as well.
ï Cryogenic Engine is also in use.
6. CRYOGENIC FUELS
ï Cryogenic propellant - the fuel and the oxidizer
ï super cooled gases -temperature lower than the freezing point.
ï To store them is difficult task
ï 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.
ï Nitrogen, hydrogen, oxygen, helium argon, neon, etc,
ï Liquid oxygen being the oxidizer and liquid hydrogen being the fuel.
ï Liquid oxygen boils at 297oF and liquid hydrogen boils at 423oF.
7. Components Of Cryogenic
Rocket Engine
ï Thrust chamber or combustion chamber
ï Igniter
ï Fuel injector
ï Fuel turbo-pumps
ï Valves
ï Regulators
ï Fuel tanks
ï Rocket engine
ï Nozzle
Among them, the combustion chamber & the nozzle are the
main components of the rocket engine.
20. CONCLUSION
âą The area of Cryogenics in Cryogenic Rocket Engines is a
vast one.
âą Developments in the field of Rocket Engineering.
âą Cryo propelled rocket engines are having a great demand
in the field of space exploration.
âą Due to the high specific impulse obtained during the
ignition of fuels they are of much demand.
