ADMITTANCE TECHNIQUES IN HIGH SPEED FLUTTER MODEL TESTING. PART I. EXPERIMENTAL RESULTS
BOEING CO SEATTLE WASH
Pagination or Media Count:
A new method of high speed flutter model testing is presented. The method obtains free flight flutter information from restrained models in the wind tunnel through the use of mechanicalADMITTANCE MEASUREMENTS. Flutter test data for a representative high speed wing-body configuration are presented at a Mach number of 1.5. Brief descriptions of the applicatio of a mittance techniques in the determination of aerodynamic data, in the determination of control surface transfer functions, and in the determination of atmospheric gust loads through elastic model tests are presented together with recommendations for future research in this area.
