Hybrid Propulsion
Nammo Raufoss has since 2004 invested and actively worked on the development of hybrid rocket propulsion systems.

A hybrid rocket engine has several interesting and advantageous capabilities that solid propellant based rockets often lack:

  • Inherent safety -> no explosives since the liquid oxidizer and fuel is separated in two tanks
  • Throttling capability -> broad range of thrust throttling which provide on demand impulse management
  • On demand termination -> a hybrid rocket motor can if needed be terminated on demand 
  • Re-ignition -> a hybrid rocket motor can if needed be re-ignited on demand multiple of times
  • High-performance -> several hybrid rocket propellants produces specific impulse levels superior to that of solid propellants

Nammo state-of-the-art hybrid rocket propulsion technology has demonstrated all the above listed capabilities within a compact and non-toxic (green) propulsion package.
