ISRO has made significant progress in designing and developing a semicryogenic engine (SE2000), a liquid oxygen/kerosene engine with 2,000 kN thrust.
It will power the semicryogenic booster stage (SC120) of the Launch Vehicle Mark-3 (LVM3).
The first successful hot test of the Engine Power Head Test Article (PHTA) was conducted at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu.
The test demonstrated smooth ignition and boost strap mode operation for 2.5 seconds.
Purpose of the Test: To validate the integrated performance of critical sub-systems with short-duration hot firing (2.5 seconds).
The engine parameters matched predictions, confirming expected performance.
ISRO plans a series of tests on PHTA to further validate and fine-tune performance before realizing the fully integrated engine.
Impact on LVM3 Rocket:
The Liquid Propulsion Systems Centre (LPSC) is developing the semicryogenic propulsion engine and stage.

Impact on LVM3 Rocket:
The Liquid Propulsion Systems Centre (LPSC) is developing the semicryogenic propulsion engine and stage.
The SC120 stage (with SE2000 engine) will replace the current core liquid stage (L110) of LVM3.
This upgrade, along with an uprated cryogenic stage, will enhance payload capacity from 4 tonnes to 5 tonnes in Geosynchronous Transfer Orbit (GTO).
