The AR801R is a tested and proven, light-weight, single rotor, liquid cooled engine with integrated reduction drive. It has been designed and developed specifically for existing and future UAVs requiring 35 to 55 bhp.
UAV DESIGN FEATURES
Exceptionally high power to weight ratio.
Reduction drive giving high propeller effciency.
Low levels of vibration.
Economical fuel consumption.
ENGINE TYPE Single rotor Wankel-type engine.
CAPACITY Single rotor - 294cc.
POWER OUTPUT 40 bhp at 6,000 engine rpm. Alternatively 51 bhp at 8,000 rpm (carburettor); or 60 bhp at 8,000 rpm (EFi).
WEIGHT 56lb (25.4kg) as illustrated, including 2 kW generator. Installed weight with cooling system is around 65lb (29.5kg).
DIRECTION OF ROTATION Anti-clockwise (looking at prop flange).
FUEL ConSUMPTION 0.52lb/bhp hr at 70% cruise = typically 2.0 lmp gallon/hr (2.4 US gall or 9.1 litres).
VIBRATION LEVEL Nominally zero (± 20cm gm) radial imbalance. Peak-to-mean instantaneous torque fluctuation is 4 approx.
IGNITION SYSTEM Electronic CD type with magnetic triggering. 12 or 28 volt option. Fully duplicated system firing spark plugs.
FUEL TYPE Regular grade (min 92 RON) Mogas (with or without lead) or AVGAS (100LL)
