Hyderabad startup Skyroot Aerospace test-fires upper stage rocket engine “Raman”


SkyrootAerospace, a city-based startup has successfully test-fired here its upper stage rocket engine named ‘Raman, which can place multiple satellites into orbit, a top official of the firm said on Thursday.


Founded by former scientists of the Indian Space Research Organisation (ISRO), Skyroot is into building India’s first privately built space launch vehicles.


The company was tightlipped on when the rocket engine was test-fired.


“We demonstrated India’s first 100 per cent 3D-printed Bi-Propellant Liquid Rocket Engine injector. Compared to traditional manufacturing this reduced the overall mass by 50 per cent, reduced total number of components and lead time by 80 per cent. The engine is capable of multiple restarts enabling them to insert various satellites into multiple orbits in a single mission,” Pawan Kumar Chandana, Co-Founder and CEO, Skyroot Aerospace said.


Two of the firm’s rocket stages are getting ready for test firing in six months, he added.

Skyroot has developed in-house software for launch vehicle guidance, navigation and control functions and testing for onboard avionics modules is in progress and the firm is targeting its first launch vehicle in December 2021, Naga Bharath Daka, Co-Founder and Chief Operating Officer, Skyroot said.


“Our first launch vehicle ‘Vikram-I’ which is under manufacturing and targeting launch in Dec 2021, hosts an Orbit Adjustment Module (OAM) at the top which gives the final burn and inserts multiple satellites into space. In an ‘Indias first’, we successfully test-fired its liquid engine,” he said. Skyroot will highly benefit from the newly-created Indian National Space Promotion and Authorisation Centre (IN-SPACe)which allows access to ISRO’s testing and launch range facilities, Naga Bharath Daka said.
