MLG-500 Propulsion System

The MLG-500 Rocket Propulsion System has been developed as a compact and reliable unit for applications in the UAV industry. Its small size and high thrust make it highly suitable for primary propulsion systems for short duration purposes or sustained boosting of small-scale vehicles.


MLG-500 is a liquid propellant (liquid oxygen / Jet A-1) rocket motor producing 500 pounds of thrust. It is a regeneratively-cooled unit allowing reliable sustained operation and potential re-ignition during flight. It is designed for incorporation into a combined-cycle rocket/ramjet propulsion system currently under development.
