Why New Aircraft Engine Ideas Rarely Succeed

Aircraft owners and pilots often bemoan the lack of new technology in aircraft engines and complain--accurately--that most airplane engines are basically 1960s tech. But as Paul Bertorelli points out in this video, it’s not for lack of trying. And it’s not necessarily the new engine itself that fails to get traction, but the company’s support--or lack thereof. CORRECTION: The Rotax V-6 engine had single, not dual overhead camshafts.
