ISRO successfully test cryogenic engine of GSLV Mark 3 rocket
The Indian Space Research Organisation (ISRO) has successfully conducted hotbed test of the indigenously developed high-thrust cryogenic engine (CE20) of the GSLV Mark 3 (LVM3) rocket for the upper stage.
The long-duration test was conducted at ISRO Propulsion Research Centre at Mahendragiri, Tamil Nadu and lasted for 640 seconds. It was conducted with Mixture Ratio Controller (MRC) in a closed loop mode.
- The CE20 uses Liquid Hydrogen at -253 degrees C and Liquid Oxygen at -193 degrees C as propellants and generates power of approximately 2 MW.
- It has been developed indigenously by Mahendragiri based Liquid Propulsion System centre (LPSC).
CE20 engine already has undergone two short-duration tests for engine ignition and steady state performance. In 2015, the first developmental engine completed different hot tests in various operating regimes. In the next the engine will be vacuum tested in the high altitude test facility as part of the flight acceptance test.
This test is considered as phenomenal achievement in the shortest time. It will boost India’s capability to launch heavier satellites into higher orbits and is capable of doubling the capacity of payloads that can be carried into space.
GSLV Mark 3 rocket is the biggest rocket made in India and capable of launching four-tonne satellites into geosynchronous orbit. India is sixth spacefarer after US, Russia, the European Space Agency (ESA), China and Japan to develop a cryogenic engine.
