"Revolutionary Jet Completes First Flight with Engine Featuring No Moving Parts"
Wave Engine Corp., a Baltimore start-up, has successfully flight-tested a jet engine with no moving parts, using pressure waves instead of rotating parts to produce thrust. The technology, a contemporary variation of the pulsejet engine, has the potential to significantly reduce the cost and complexity of jet propulsion. While pulsejet designs have been around for a century, they have been largely dismissed by the commercial aviation industry due to noise and regulation issues. However, companies like Boeing, Pratt & Whitney, and General Electric are exploring pulsejet engine technology for future applications. Wave Engine Corp. has officially launched its J-1 engine, which has 50+ pound-force of thrust, and is aiming to develop engines with up to 250 pound-force for larger aircraft.
