ISRO Achieves Breakthrough With Successful First Hot Test Of 200T LOX-Kerosene Semi-Cryogenic Engine

The Indian Space Research Organisation (ISRO) has achieved a significant breakthrough in advancing its space mission capabilities with the successful completion of the first major hot test of the Lox-Kerosene 200T thrust semi-cryogenic engine. 

The test was conducted at the Semi Cryo Integrated Engine Test Facility (SIET) at ISRO Propulsion Complex (IPRC), Mahendragiri, a facility that was dedicated to the nation by Prime Minister Narendra Modi during his visit to Thiruvananthapuram.

The semi-cryogenic engine, which operates on a LOX-Kerosene propellant combination, is being developed to enhance the payload capacity of the LVM3 launch vehicle and support future launch missions. 

The first ignition trial of this engine was successfully conducted on 2 May 2024, marking a crucial step in its development.

Prior to this full-scale test, multiple injector elemental level ignition trials were conducted at the Propulsion Research Laboratory Division (PRLD) facility of VSSC.

These tests were essential for characterizing the ignition process and ensuring its effectiveness before the full engine trial.

With this achievement, ISRO moves closer to enhancing its heavy-lift launch vehicle capabilities, a crucial step in strengthening the country's position in global space exploration.
