Performance Work Statement (PWS) Heavy Fuel Wankel Rotary Engine Design and Development

31 May 2022

C.1 Background

The DEVCOM Army Research Laboratory (ARL) requires a novel lightweight compact heavy-fuel rotary engine for future tactical unmanned aircraft (FTUAS). The engine must meet the following minimum requirements:

Overall system weight: <20 pounds (lbs) max engine mass Power: 25 horsepower (hp) up to 20,000 feet (ft) Overall efficiency: <0.4 pound per horsepower-hour (lb/hph) Fuel types: Heavy Fuel - Kerosene Spark Plug Lifetime: 100+ Hours if spark plug is used

ARL identified that the AIE’s patented Self-Pressurizing-Air Rotor Cooling System (SPARCS), their unique dual spring apex seal system, and their unique dual spark system solved the inherent Wankel engine problems, and AIE has the potential to advance this base engine to incorporate turbocharging, direct injection, combustion chamber optimization, weight reduction and engine optimization to meet the Government requirements.
