Solid Fuel Ducted Ramjet (SFDR)

 

What to study?

For Prelims and Mains: About SFDR and ramjet, India’s technological missions and significance of such missions.

 

Context: Defence Research and Development Organisation (DRDO) successfully flight tested the second indigenously developed ‘Solid Fuel Ducted Ramjet (SFDR)’ propulsion based missile system.

 

Solid Fuel Ducted Ramjet (SFDR): It is a missile propulsion technology jointly developed by India and Russia.

 

Significance:

  • It will help both India’s surface-to-air and air-to-air missiles to perform better and enhance their strike range, making them more lethal.
  • With it, India can have fastest long-range missiles in two categories, providing full-fledged and multi-layered aerial protection from hostile attacks.
  • Its successful use in missiles will mark India’s entry into select club of nations that use next-generation missile technology against manoeuvring targets, compromising effectiveness of conventional missiles.

 

What is ramjet?

Ramjet is a form of air-breathing jet engine that uses the vehicle’s forward motion to compress incoming air for combustion without a rotating compressor. Fuel is injected in the combustion chamber where it mixes with the hot compressed air and ignites. A ramjet-powered vehicle requires an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust.
