Solid Fuel Ducted Ramjet Propulsion
DRDO carries out a successful demonstration of Solid Fuel Ducted Ramjet (SFDR) technology from the Integrated Test Range (ITR), Chandipur, Odisha. It validates SFDR as an advanced missile propulsion technology for intended missile applications.
Solid Fuel Ducted Ramjet (SFDR) Propulsion Technology:
| Dimension | Key Details |
|---|---|
| Concept | Advanced missile propulsion concept that merges the benefits of a solid fuel rocket with air-breathing ramjet engines. |
| Ramjet engine | A type of air-breathing jet engine that uses the missile’s forward speed to compress incoming air, rather than relying on complex rotating parts like conventional jet engines. |
| Working principle | Uses atmospheric oxygen for combustion, reducing onboard oxidiser requirement. |
| Key benefits | Longer engagement range and sustained high-speed cruise. |
| Components | Booster, SFDR motor, and controlled fuel-flow mechanism. |
| Intended use | Intended mainly for advanced long-range air-to-air missiles. |
| Capability status | Places India among a limited group of countries with SFDR capability. |
