Summary:
Team Aeroelasticity & Vibration aim to develop effective flutter test technique for the high-speed vehicle that could replace expensive and complicated conventional wind tunnel. The key challenge here is to simulate aerodynamic pressure on test structure with few concentrated forces exerted through shakers. The similar concept of “Dry Wind Tunnel” (DWT) has been developed for the subsonic region, but not for the supersonic region. We understand that the necessity of flutter testing technique like DWT for supersonic aircraft is prime. Therefore, this group is focused on establishing theoretical stand at this point for the ultimate experimental purpose.
