Vikas Engine Invention in India
- The first production of Vikas engines used a few imported French components that were later replaced by domestic equivalents.
- It is used in the Geosynchronous Satellite Launch Vehicle (GSLV) and the Polar Satellite Launch Vehicle (PSLV) series of expendable launch vehicles for use in space.
- The Vikas engine powers the PSLV second stage, boosters and GSLV Mark I and II second stages, and the GSLV Mark III core stage.
- The propellant charge for Vikas engine in PSLV, GSLV Mark I and II is 40 tonnes, whereas, in GSLV Mark III, it is 55 tonnes.
- Two new Vikas engines are fascinating: HPVE (High Pressure or High-Speed VIKAS Engine) and HTVE (High Thrust VIKAS Engine).
- The recent test was conducted in Tamil Nadu at the ISRO Propulsion Complex in Mahendragiri.
- It was conducted to observe the engine performance under conditions that were not optimal, like changing the fuel to oxidizer ratio or fuel chamber pressure.
- Regarding the qualification of the Vikas engine for the Gaganyaan mission, two engines were tested already under nominal operating conditions for 480 seconds.
Who invented the Vikas engine?
Vikas engine was invented by the scientists of ISRO, the one who played an important role, i.e. Nambi Narayanan. The launch vehicle's first stage, which used solid propellants, is qualified already for the mission.
