The Raman engine is a bipropellant rocket engine manufactured by Skyroot Aerospace that will be used in its Vikram family of rockets.[1] It is named after Indian Nobel laureate C. V. Raman.
Description
[edit]It uses unsymmetrical dimethylhydrazine and hypergolic propellants.[2] Its injector plate is completely 3D printed. This engine will be used in a cluster of 4 in the fourth stage of the Vikram 1 rocket, which can produce a thrust of 3.4 kN each producing 850 N of thrust, which is lower than many other rocket engines, but is required for precise orbit adjustments.[3][4]
Development and testing
[edit]- On 12 August 2020, Skyroot Aerospace successfully tested the engine for the first time.[5]
- Skyroot Aerospace tested the Raman-2 engine, designed for vacuum conditions, by firing it for 200 seconds on a ground test stand. The team used water injection to mitigate flow separation in the vacuum-optimized nozzle, allowing accurate testing at sea level. This test provided critical data for the Vikram-1 rocket's fourth stage, advancing India's private space efforts. [6]
