- ISRO recently successfully conducted the hot test on a semi-cryogenic engine (SE2000).
- This test is known as the Power Head Test Article (PHTA) and the first hardware test for the development of semi-cryo engines.
- The cryogenic engine uses liquid oxygen and liquid hydrogen.
- Whereas a semi-cryogenic engine uses a liquid oxygen – kerosene combination, where kerosene is readily storable.
- This combination offers advantages like the high-density impulse, less toxic (with respect to storage) and cost-effectiveness.
