Solid Fuel Ducted Ramjet (SFDR) Technology

  • It is a missile propulsion system that combines a decreased smoke, nozzle-less missile booster with a thrust-modulated, ducted rocket.
  • A joint R&D effort between India and Russia resulted in the development of the SFDR, which was tested in 2018. It had reached Mach 3 speed.
  • The device uses a Ramjet engine that breathes air while burning solid fuel.
  • The Ramjet, in contrast to solid-propellant rockets, absorbs oxygen from the atmosphere while in flight. As a result, it is lightweight and has a greater gasoline capacity.
  • Range: Air targets in the ranges from 70 - 340 km.
