Vikas engine completes test for Gaganyaan
GS Paper- 3 (Space Technology)
The Indian Space Research Organisation (Isro) said it successfully completed a 25-seconds qualification test of the high thrust Vikas engine for the Gaganyaan programme at the Isro Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu.
- With regard to the Vikas engine qualification for the Gaganyaan programme, two engines have already undergone tests under nominal operating conditions for a total duration of 480 seconds.
- The test carried out today is to verify the robustness of the engine by operating beyond its nominal operating conditions (fuel-oxidiser ratio and chamber pressure).
- VIKAS (an acronym for Vikram Ambalal Sarabhai) is a family of liquid-fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre since the 1970s.
- The early production VIKAS engines used imported French components which were later replaced by domestically produced equivalents.
- It is used in the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV) series of expendable launch vehicles for space launch use.
- VIKAS engines are used to power the second stage PSLV, boosters and second stage of GSLV Mark I and II and now the first stage of GSLV Mark III (LVM3).
- This is another milestone in the human-rating of systems and the launch vehicle for the human space programme.
- Just last week, the space agency had conducted a 720-seconds qualification test of the cryogenic engine — CE-20 — to be used for Gaganyaan.
