Minimum mass sizing of a large low-aspect ratio airframe for flutter-free performance [PDF]
A procedure for sizing an airframe for flutter-free performance is demonstrated on a large, flexible supersonic transport aircraft. The procedure is based on using a two level reduced basis or modal technique for reducing the computational cost of ...

Transonic flutter study of a wind-tunnel model of an arrow-wing supersonic transport [PDF]
A 1/20-size, low-speed flutter model of the SCAT-15F complete airplane was tested on cables to simulate a near free-flying condition. Only the model wing and fuselage were flexible.
