Complex testing of ISRO’s ‘Semi-Cryogenic Engine’ successful

Bengaluru (Karnataka) – ISRO has successfully conducted a crucial test in the development of the ‘Semi-Cryogenic Engine.’ The test aimed to ignite the ‘pre-burner’ to start the ‘Semi- Cryogenic Engine,’ and it has been successful. The test was conducted on 2^ndMay. This engine will enhance the payload capacity (capacity to carry load of the machinery or humans) of ISRO’s GSLV Mk III rocket. This rocket was previously used to launch Chandrayaan-3, and it will also be utilised in the Chandrayaan-4 mission.

What is a Cryogenic Engine?

The energy required for the launch of a rocket is provided by this engine. The fuel used in this technology is kept at extremely low temperatures. This temperature is even less than minus 150 degrees Celsius. The first successful test of this indigenous engine was conducted in 2003; however, it took another 11 years for successful flight application. Currently, India has two Cryogenic Engines – ‘CE-7.5’ and ‘CE-20’. These engines use oxygen and hydrogen as fuel, whereas the newly developed Semi-Cryogenic Engine uses refined kerosene instead of liquid hydrogen as fuel. Liquid oxygen is used as an oxidiser in these engines.
