ISRO successfully conducted a 175-tonne thrust hot test of its semi-cryogenic engine at the IPRC in Mahendragiri.
The test of the Power Head Test Article (PHTA) focused on steady-state operation and turbopump performance.
This engine is being developed to replace the current L110 core stage of the LVM3 launch vehicle.
The system uses cleaner, non-toxic propellants, specifically liquid oxygen and purified kerosene (isrosene).
