The U.S. Armys Shadow unmanned aerial vehicle UAV is an indispensable tool in modern military intelligence acquisition. The Shadow is powered by one UEL 1100 engine, a single-rotor Wankel engine. However, at high-altitude, low-temperature conditions, engine operation may be compromised due to insufficient oil delivery to the engine. To develop a better understanding of the engine systems oil delivery, we have evaluated the performance of the oil pump. Testing consisted of measuring oil pumping capability at various temperatures and speeds, and with different grades of oil.
