 The Indian Space Research Organisation on Sunday tested two scramjet engines, attached to a rocket, from Satish Dhawan Space Centre, Sriharikota in Andhra Pradesh. ISRO called it an important milestone in its endeavour to design and develop advanced air breathing engines for future space transportation system.

Here’s all you need to know about these scramjet engines:
 
•         The engine is based on an ‘air breathing propulsion system’ wherein the engine carries hydrogen (as fuel) but takes oxygen (as oxidiser) from the atmospheric air. Conventional rocket engines carry the oxidiser along with them.
 
•         A scramjet engine, thus, reduces rocket load and cost, and is able to carry heavier payload.
 
•         The engine tested by ISRO took a hypersonic flight at Mach 6 (7408.8 km/h).  
 
•         India is now the fourth country in the world to flight test a scramjet engine.
 
•         Apart from rockets and missiles, the engine can find its applications in planes for the purpose of commercial travel by considerably reducing the travel time.
