Rotron Rotary UAV Engines

Rotron RT300 Rotary UAV Engine

ROTRON RT300LCR

SUITABLE FOR UAVS REQUIRING 32HP

The Rotron RT300 LCR rotary engine is a proven and durable solution for UAV platforms looking for high power-to-weight ratio. This compact, single rotor engine utilises the most advanced rotary technology and premium materials to produce industry leading performance in a lightweight, reliable and efficient package.

  • High power-to-weight ratio with increased efficiency
  • Small engine size allows greater fuel and payload flexibility for multi-mission capability
  • Low levels of torsional vibration and zero radial vibration at mid-to-high rpm range
  • 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
