The Indian Space Research Organisation’s (ISRO) successfully conducted the hot test of scramjet engine.
What is it?
- In an air-breathing scramjet engine, air from the atmosphere is rammed into the engine’s combustion chamber at a supersonic speed of more than Mach two.
- Process –
- In the chamber, the air mixes with the fuel to ignite a supersonic combustion but the cruiser’s flight will be at a hypersonic speed of Mach six to seven.
- So it is called supersonic combustion ramjet or Scramjet.
- Air from the atmosphere was then rammed into the scramjet engine’s combustion chamber at a supersonic speed.
- The air mixed with the atomised fuel, the fuel was ignited and the scramjet engine revved into action.
- Benefits – Mastering the air-breathing scramjet technology will lead to the development of hypersonic missiles, faster civilian air transportation and facilities for putting satellites into orbit at a low cost.
