Transcript

  • 1. CRYOGENIC ROCKET ENGINE
  • 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.
  • 5. Classification Of Space Propulsion System
  • 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 NozzleAmong them, the combustion chamber & the nozzle are themain components of the rocket engine.
  • 8. ROCKET ENGINE POWER CYCLES1. Gas pressure feed system
  • 9. 2. Gas-Generator Cycle
  • 10. 3. Staged Combustion Cycle
  • 11. COMBUSTION IN THRUST CHAMBER
  • 12. Injector Plate
  • 13. Testing Of Cryogenic Rocket Engine
  • 14. VULCAIN ENGINE
  • 15. RL 10 Cryogenic CE 20 Cryogenic Engine Engine
  • 16. Advantages High Energy per unit mass Clean Fuels Economical
  • 17. Disadvantages Highly reactive gases Leakage Hydrogen Embrittlement Zero Gravity Condition
  • 18. 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.
