The Vikram (Sanskrit, lit. 'Brave'; Namesake: Vikram Sarabhai[1]) is a family of small-lift launch vehicles being developed by Skyroot Aerospace, an Indian startup aerospace company.
Before a full orbital launch, a suborbital flight of rocket designated Vikram-S was performed on 18 November 2022 by the name of mission Prarambh (Sanskrit, lit. 'beginning').[2][3]
Skyroot Aerospace has successfully tested Vikram-S, the sounding rocket. Vikram-I is currently under development while the heavier launchers of Vikram-II and Vikram-III are proposed.
The Vikram-I, first rocket in the series, has three solid fuel-powered stages each with a burn time ranging between 80 and 100 seconds and the final stage is Raman engine (Sanskrit, lit. 'enchanting', Namesake: C.V. Raman). The Raman engine is powered by MMH and NTO liquid fuels in a cluster of four engines that generate 3.4 kN thrust. These Raman Engines will be used to do final adjustments in the orbit of the stage.[4] Vikram-I is designed to lift 290 kg to a 500 km Sun synchronous polar orbit (SSPO) and 480 kg to 45º inclination in a 500 km low Earth orbit (LEO).[5][6]
