Some oscillatory aerodynamic derivatives for wing pitch and translation, and control-surface rotation have been found from measurements in a low-speed wind tunnel. The wing was a modified cropped delta of biconvex circular-arc ...

An aeroelastic model aircraft of slender planform has been tested in a wind tunnel at low subsonic speeds. The tests comprised measurement of the resonant frequencies and dampings of the first five symmetric modes of ...

Two rectangular wings of aspect ratio 4 were flutter tested in a supersonic wind tunnel at Mach numbers 1.6 and 2.0 using a technique in which a structural stiffness was varied to give flutter at the Mach number. The results ...
