What Is The Full Form Of PSLV?
Full Form Of PSLV Is a Polar Satellite Launch Vehicle
Some Details About PSLV
PSLV stands for Polar Satellite Launch Vehicle. It’s an expendable launch vehicle of India which is developed and operated by the Indian Space Research Organization (ISRO). It’s third generation launch vehicle of India and also the primary satellite launch vehicle of India which is supplied with liquid stages. PSLV was developed to enable India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits. It may be wont to launch small size satellites into geostationary transfer orbit (GTO).
India used PSLV on 15 February 2017 to launch 104 satellites in polar orbit around the Earth. From 1994 to 2017, India has launched 48 Indian satellites and 209 foreign satellites through PSLV. Furthermore, it’s also accustomed to launch India’s two spacecraft, i.e. Chandrayan-1 in 2008 and Mars Orbiter Spacecraft in 2013. Later, these spacecraft traveled to Moon and Mars respectively
PSLV is additionally called “the Workhorse of ISR .”. It earned this title after consistently launching various satellites to Low Earth Orbits, i.e. IRS series of satellites. It can carry up to 1,750 kg of the load to Sun-Synchronous Polar Orbits of 600 km altitude. It’s given 6 solid rocket strap-on motors to spice up the thrust in its PSLV-G and PSLV-XL variants within the first stage. It is a four-stage launch vehicle that uses solid and liquid propulsion systems alternately, i.e. First and third stages use solid rocket motors while the second and fourth stages use liquid rocket engines
- First Stage (PS1): The first stage uses the S139 solid rocket motor augmented by 6 solid strap-on boosters. The maximum thrust generated in this stage is 4800 kN.
- Second Stage (PS2): An Earth storable liquid rocket engine is used for the second stage of PSLV. It is known as the Vikas engine and it is developed by the Liquid Propulsion System Centre. The maximum thrust generated in this stage is 799 kN.
- Third Stage (PS3): In this stage of PSLV, a solid rocket motor provides the required thrust after the atmospheric phase of the launch. The maximum thrust generated in this stage is 240 kN.
- Fourth Stage (PS4): It is the uppermost stage of PSLV. It comprises two Earth storable liquid engines. The maximum thrust generated in this stage is 7.6 X 2 kN.
