- ISRO successfully tested pre-burner ignition for the development of its semi-cryogenic propulsion systems.
- The pre-burner ignition test article will support the Powerhead system of the semi-cryogenic engine. The ignition trial on the test article was held on May 2.
- Smooth and sustained ignition of the pre-burner is important for the starting of the engine.
- The trial was held at the cryo-integrated engine test facility at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu.
Semi-cryogenic engine
- ISRO is developing a semi-cryogenic engine which works on a propellant combination of liquid oxygen and kerosene.
- Its main aim is to increase the payload capability of launch vehicle Mk III (LVM3) and future launch vehicles.
- A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel and oxidizer.
- Cryogenics is the study of the production and behaviour of materials at extremely low temperatures.
