Unmanned Aerial Vehicle (UAV) Engine Innovative and Durable Sealing Techniques for Increased Power and Efficiency

Technical Abstract Rotary engines, due to their inherently high power density, have become popular as Unmanned Arial Vehicle (UAV) propulsion systems. Their high specific power places abnormally high loads on critical components. The apex seal is universally recognized as critical to sealing the high combustion pressures and vulnerable to wear at high speeds. Patpower has 14 years of experience developing the heavy fuel variant of the rotary engine and is very aware of the severity of the apex seal operating conditions. The PatPower engines use “conventional” apex seals that are an industry standard but we are aware of the seal’s limitations and have conceived of a potential improvement. The opportunity to implement the improved apex seal has been inhibited by the scope of work required to validate its benefits. This proposal seeks funding to accomplish that work.
