2. INTRODUCTION
What is Cryogenics?
Cryogenic fuels can be used as rocket engine fuel.
Cryogenic Engines are rocket motors.
3. 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.
4. 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.
6. CRYOGENIC FUELS
Cryogenic 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.
7. 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.
20. CONCLUSION
• The area of Cryogenics in Cryogenic Rocket Engines is a
vast one.
• Developments in the field of Rocket Engineering.
• Cryo propelled rocket engines are having a great demand
in the field of space exploration.
• Due to the high specific impulse obtained during the
ignition of fuels they are of much demand.
