Solid Fuel Ducted Ramjet

News: Defence Research and Development Organisation (DRDO) successfully carried out a flight demonstration based on Solid Fuel Ducted Ramjet (SFDR) technology from Integrated Test Range Chandipur off the coast of Odisha.

Details:

  • All the subsystems, including the booster motor and nozzle-less motor, performed as expected. During the test, many new technologies were proven, including Solid Fuel based Ducted Ramjet technology.
  • The performance of the missile was monitored using the data captured by Electro Optical, Radar and Telemetry instruments deployed by ITR and confirmed successful demonstration of the mission objectives.
  • The launch was monitored by senior scientists of various DRDO labs, including Defence Research & Development Laboratory (DRDL), Research Centre Imarat (RCI) and High Energy Materials Research Laboratory(HEMRL).
  • Successful demonstration of Solid Fuel based Ducted Ramjet technology has provided DRDO with a technological advantage which will enable it to develop long range air-to-air missiles.
  • At present, such technology is available only with a handful of countries in the world. During the test, air launch scenario was simulated using a booster motor.
  • Subsequently, the nozzle-less booster accelerated it to the required Mach number for Ramjet operation.

What is ramjet?

  • Ramjet is a form of air-breathing jet enginethat 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.
