 Why in news

  • The Defence Research and Development Organisation (DRDO) has successfully conducted a Supersonic Combustion Ramjet (Scramjet) engine ground test, advancing India's hypersonic missile tech. 

Scramjet Engine

  • A scramjet engine (Air-breathing engines) is an advanced ramjet that uses supersonic airflow for combustion, enabling faster speeds

  • It uses liquid hydrogen and liquid oxygen for thrust, offering better fuel efficiency.  

  • Unlike a turbojet engine, ramjets and scramjets have no moving parts, consisting only of an inlet, combustor (with fuel injector and flame holder), and a nozzle. 

  • Scramjets are key to hypersonic vehicles to handle airflows at speeds above the speed of sound

Hypersonic Missiles

  • Traveling at speeds greater than Mach 5 (over 5,400 km/h),  bypass air defences with high-speed, high-impact strikes.  

  • These missiles are also more maneuverable, which allows them to more easily evade air defence systems.

  • The two types of hypersonic weapons systems are Hypersonic Glide Vehicles (HGV) and Hypersonic Cruise Missiles.

  • The HGVs are launched from a rocket before gliding to the intended target 

  • HCMs are powered by air-breathing high-speed engines or ‘scramjets’ after acquiring their target.
