Private space vehicle company Skyroot Aerospace on April 04, 2023, test-fired its 3D-printed Dhawan II engine for a duration of 200 seconds.
The engine was developed by the company for its heavier vehicle, Vikram II.
The ‘Dhawan-Il endurance test was conducted at Solar Industries’ propulsion test facility in Nagpur, Maharashtra, using an indigenously constructed mobile cryogenic engine test pad.
Earlier in November 2022, Skyroot launched India’s first privately developed rocket Vikram-S.

Dhawan II

The Dhawan cryogenic engine series of Skyroot is named in honour of Satish Dhawan.
Dhawan II builds upon Skyroot’s first privately developed fully cryogenic rocket engine – Dhawan-I, which was successfully test-fired in 2021.
It is completely indigenous and uses a super-alloy for 3D printing the engine, which reduces the manufacturing time by 95%.
It will use Liquid Natural Gas (LNG) and Liquid Oxygen (LOX) as propellants.
