Joint partnership leads to successful swirl distortion testing

An AEDC test team and members of the U.S. Air Force Academy (USAFA) partnered together recently at the Academy’s F109 turbofan test facility to apply swirl distortion to determine engine response in terms of aeromechanics, operability and performance. In July 2017 testing occurred using a fully functional and automatic swirl generator prototype to determine the response of the F109 engine to swirl with and without pressure distortion. Pictured here is the swirl generator, the blue portion at left, connected to the bellmouth. (AEDC photo)
