Context
ISRO has made significant progress in developing its semi-cryogenic propulsion systems by successfully igniting a pre-burner.
About
- The pre-burner ignition test is part of ISRO's efforts to develop a powerful semi-cryogenic engine that will use a combination of liquid oxygen and kerosene as propellants.
- This engine aims to increase the payload capacity of launch vehicles like
- Start fuel ampule: Semi-cryogenic engine ignition is achieved using a start fuel ampule which uses a combination of Triethyle Alumnide and Triethyle Boron developed by Vikram Sarabhai Space Centre (VSSC).
- Next steps include testing the engine power head and fully integrating the engine. Additionally, ISRO is working on developing a semi-cryo stage with 120 tons of propellant loading.
