Rotron Heavy Fuel UAV Engines

Rotron RT300 Heavy Fuel Rotary UAV Engine

ROTRON RT300HFE

SUITABLE FOR UAVS REQUIRING 31HP

The Rotron RT300 HFE rotary UAV engine delivers an efficient and reliable solution for use with heavy fuels. This compact, single rotor heavy fuel engine utilises advanced fuel management techniques to achieve reliablity in operation, high power-to-weight ratio, low fuel consumption and reliable starting under the most extreme of operating conditions.

  • For use with JP5, JP8 and Jet A1 heavy fuel
  • High power-to-weight ratio with increased efficiency
  • Small engine size allows greater fuel and payload flexibility for multi-mission capability
  • Fuel injection and ECU controlled altitude compensation fitted as standard
  • Higher engine endurance lifecycle
  • Available in pusher or tractor (puller) configurations, with either direct or reduction drive
