AR682 – 75 BHP

ROTARY ENGINE FOR UAVS

The AR682 engine has been developed to power UAVs which have limitations on propeller diameter and thereby cannot use a reduction drive. It provides 75 BHP at 6000 rpm in an ultra-compact envelope. In 1994 this power unit with all accessories successfully completed a customer witnessed 150 hour FAR 33-type endurance test.

UAV DESIGN FEATURES

  • Exceptionally high power to weight ratio
  • Low Cross Sectional Area
  • Economical fuel consumption
  • Low levels of vibration
