Cryogenic engines (india)

  1. 1. CRYOGENIC ENGINE KARTHIK NAYAK
  2. 2. GEO-SYNCHRONOUS SATELLITE LAUNCH VEHICLE DATE : April 15, 2010 PLACE : Satish dhawan space centre Shar, Sriharikota. SPECIALITY : It was the first satellite which was using INDIA developed cryogenic engine. STATUS : Failure.
  3. 3. THE COOLEST HOT ENGINE
  4. 4. Propulsion system: The power Centre of a launcher. Specific Impulse (Isp): Index of efficiency of a propulsion system. Isp= Thrust / Weight flow rate of propellants. Traditionally expressed in seconds. Ispof different propulsion systems (sea-level): Solid propulsion –265 s Earth-storable liquid propulsion –285 s Cryogenic propulsion –450 s
  5. 5.  Operating Cycle - Gas Generator.  Propellant Combination - LOX / LH2.  Thrust Nominal (Vacuum) - 200 kN.  Operating Thrust Range - 180 kN to 220 kN.  Chamber Pressure (Nom) - 6 MPa.  Engine Burn Duration (Nom) - 595 seconds.  Total Flow rate - 462 kg/s.  Nozzle Area ratio – 100.  Mass - 588 kg.
  6. 6. High Specific Impulse Non-toxic and non-corrosive propellants Non-hypergolic, improved ground safety Low density of liquid Hydrogen –more structural mass Low temperature of propellants -Complex storage & transfer systems and operations Hazards related to cryogens Overall cost of propellants relatively high Need for ignition system.
  7. 7. BECAUSE, SATELLITE ARE BECOMING HEAVIER…. INSAT 1A [1982] –1150 kg INSAT 2A [1992] –1900 Kg INSAT 3C [2002] –2750 Kg INSAT 4A [2005] –3080 kg
  8. 8. THE COOLEST HOT ENGINE
  9. 9. WE ALL HOPE IT WILL BE A SUCCESSFUL LAUNCH BY INDIA
