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

Highlights

• 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.
• 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.
• 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.

Ramjet

• It is air-breathing jet engine that operates with no major moving parts.
• It relies on the craft’s forward motion to draw in air and on a specially shaped intake passage to compress the air for combustion.
• After fuel sprayed into the engine has been ignited, combustion is self-sustaining.
• As in other jet engines, forward thrust is obtained as a reaction to the rearward rush of hot exhaust gases.
