What is the News?
Defence Research and Development Organization(DRDO) has successfully flight-tested Solid Fuel Ducted Ramjet (SFDR) booster at the Integrated Test Range (ITR), Chandipur off the coast of Odisha.
What is Solid Fuel Ducted Ramjet(SFDR)?
SFDR is a missile propulsion system being developed by the Defence Research and Development Organisation(DRDO).
Aim: To develop critical technologies required in the propulsion systems of future long-range air-to-air missiles.
Technology: The system is based on a solid fuelled air-breathing ramjet engine. Unlike the other solid-propellant rockets, the Ramjet takes up oxygen from the atmosphere during flight without the need for cylinders. Due to this, it is light in weight and can carry more fuel, making it more efficient.
What is the significance of this development?
Firstly, it enables the missiles to intercept aerial threats at very long range at supersonic speeds.
Secondly, it has provided DRDO with a technological advantage that 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.
