DRDO conducts successful flight test of SFDR missile propulsion system

new delhi: the drdo said it successfully carried out a flight test of its solid fuel-ducted ramjet (sfdr) missile propulsion system on friday morning at the chandipur test range in odisha.       "all the subsystems, including the booster motor and nozzle-less motor, performed as expected (during the flight test)," the statement issued by government-run defence research and development organisation (drdo) said.    at present, the sfdr missile propulsion technology is available only with a handful of countries in the world, it said.     "during the test, air launch scenario was simulated using a booster motor. subsequently, the nozzle-less booster accelerated it to the required mach number (speed) for ramjet operation," it said.    successful demonstration of sfdr technology has provided drdo with a technological advantage which will enable it to develop long range air-to-air missiles, it added.
