AR731 - 38 BHP - UAV TARGET ENGINE
|
The AR731 has the highest power to weight ratio of any rotary
engine in the world. It has been specifically designed and developed to be the
ultimate engine for small target drones and short-life UAVs. TBO is 10 to 50 hours depending on duty cycle.
This remarkable power unit offers many advantages over previously competitive
twin cylinder 2-stroke engines.
Design Features
- Exceptionally high power to weight ratio.
- Small frontal area concentric to propeller axis.
- Low specific fuel consumption (allowing greater range or payload).
- Low levels of vibration.
- Both tractor and pusher versions available.
