On 5th March 2021, DRDO has successfully conducted the successful flight test of the Solid Fuel Ducted Ramjet technology. The flight test was conducted from Integrated Test Range at Chandipur, Odisha. The air launch scenario was also simulated during the flight test using the booster motor. After that, the nozzle-less booster accelerated the motor to the required Mach number for the operating the Ramjet.

  • During the Ramjet test, it was observed that, all the subsystems such as booster motor and nozzle-less motor performed as per the expectation of the Defence Research and Development Organisation.
  • Further, the flight test proved many of the new technologies including the Solid Fuel based Ducted Ramjet technology.
  • The performance of missile was monitored using the data which was captured by Electro Optical, Radar and Telemetry instruments.
  • The Successful flight test of the Solid Fuel based Ducted Ramjet technology now provides the Defence Research and Development Organisation with several technological advantage.
  • This would now enable the DRDO to develop a long-range air-to-air missile.

Solid Fuel Ducted Ramjet

The Solid Fuel Ducted Ramjet missile propulsion system developed by the DRDO. The Organisation developed the project with the aim of developing the critical technologies which are required in the propulsion systems future long range air-to-air missiles of India. It is a missile propulsion system that comprises of the thrust modulated ducted rocket along with the reduced smoke nozzle-less missile booster. Thrust modulation of the system is achieved through a hot gas flow controller. Solid Fuel Ducted Ramjet uses a solid fuelled air-breathing ramjet engine.
