Re: Pslv isro
As you asking I am telling Polar Satellite Launch Vehicle, (PSLV) is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO). Polar Satellite Launch Vehicle, (PSLV) was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits, a service that was, until the advent of the Polar Satellite Launch Vehicle, (PSLV) , commercially available only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO): Function Medium lift launch system Manufacturer ISRO Country of origin India Cost per launch PSLV-CA 90 crore($15M) Size Height 44 metres (144 ft) Diameter 2.8 metres (9 ft 2 in) Mass PSLV-G: 295,000 kg (650,000 lb) PSLV-CA: 230,000 kg (510,000 lb) PSLV-XL: 320,000 kg (710,000 lb) Stages 4 Capacity Payload to LEO 3,250 kg (7,170 lb) Payload to SSO(600 km) 1,750 kg (3,860 lb) Payload to Sub-GTO/GTO 1,425 kg (3,142 lb) Launch history Status Active Launch sites Sriharikota Total launches 34 PSLV-G: 11 PSLV-CA: 11 PSLV-XL: 12 Successes 32 PSLV-G: 9 PSLV-CA: 11 PSLV-XL: 12 Failures 1 (PSLV-G) Partial failures 1 (PSLV-G) First flight PSLV: 20 September 1993 PSLV-CA: 23 April 2007 PSLV-XL: 22 October 2008 Notable payloads Chandrayaan-1, Mars Orbiter Mission, Astrosat Boosters (PSLV-G) - S9 No. boosters 6 Thrust 510 kN (110,000 lbf) Specific impulse 262 s (2.57 km/s) Burn time 44 seconds Fuel Hydroxyl-terminated polybutadiene Boosters (PSLV-XL) - S12 No. boosters 6 Thrust 719 kN (162,000 lbf) Specific impulse 262 s (2.57 km/s) Burn time 49 seconds Fuel Hydroxyl-terminated polybutadiene First stage Propellant mass 138,000 kg (304,000 lb) Motor S139 Thrust 4,800 kN (1,100,000 lbf) Specific impulse 237 s (2.32 km/s) (sea level) 269 s (2.64 km/s) (vacuum) Burn time 105 seconds Fuel HTPB Second stage Engines 1 Vikas Thrust 799 kN (180,000 lbf) Specific impulse 293 s (2.87 km/s) Burn time 158 seconds Fuel N2O4/UDMH Third stage Motor HPS3 Thrust 240 kN (54,000 lbf) Specific impulse 295 s (2.89 km/s) Burn time 83 seconds Fuel Hydroxyl-terminated polybutadiene Fourth stage Engines 2 x L-2-5 Thrust 15.2 kN (3,400 lbf) Specific impulse 308 s (3.02 km/s) Burn time 425 seconds Fuel MMH/MON |
