Jet engines without moving parts. Seems unlikely, but North American Wave Engine Corporation (NAWEC) CEO Daanish Maqbool has developed just that. And he did it right here in Maryland.
The idea of an engine without moving parts dates back to WWII, but problems with fuel efficiency and vibration prevented practical use at the time. NAWEC addressed the inadequacies of the WWII era engine by using pulse combustion technology developed at the University of Maryland, College Park.
NAWEC’s technology uses pressure waves to move air through the engine, the way machinery moves air through traditional engines. These pressure waves can be thought of as really powerful sound waves, Maqbool said. The new engine provides an alternative to the jet (turbine) engine. Turbine engines can come with over 10,000 moving parts, making them very expensive and impractical for private use. NAWEC’s engines provide a more affordable, simpler engine without sacrificing performance. In addition to manned aircraft, the technology will also be used in unmanned aerial vehicles.
