Isro helps test Skyroot’s Raman-II engine – Times of India

BENGALURU: Isro on Saturday said that on July 21, it demonstrated its commitment to fostering the space ecosystem in India by enabling a successful rocket-engine test conducted by startup Skyroot, at the Isro Propulsion Complex (IPRC) Mahendragiri.

The test, enabled by the Indian National Space Promotion and Authorisation Centre (IN-SPACe), took place in the Liquid Thruster Test Facility (LTTF) in IPRC.
“The test involved Skyroot’s Raman-II engine, which was designed to generate 820 Newton (Sea Level) and 1,460 Newton (Vacuum) thrust, with a nominal chamber pressure of 8.5 bar absolute,” Isro said.

The 10-second test achieved the expected performance in terms of start transient, steady state, and shut-off. Skyroot intends to integrate the Raman-II engine into the fourth stage of its launch vehicle, Vikram-I.
Raman-II, a regeneratively cooled engine, manufactured through additive manufacturing techniques, utilises Mono Methyl Hydrazine and Nitrogen Tetroxide as propellants.
“The test facility systems demonstrated normal performance during the test, meeting the engine inlet conditions at T0. The instrumentation systems also performed as expected, further ensuring the accuracy and reliability of the test results,” Isro said.
The space agency said this facilitation underscores its commitment to nurture private players, start-ups, and non-government entities (NGEs) in developing the country’s space eco-system.
“Going forward, a series of additional tests are planned to further validate and refine the Raman-II engine’s capabilities,” Isro added.
