Stiffness and damping hinge-moment derivatives have been measured on a two-dimensional aerofoil-flap combination model by a free-oscillation technique. The experiments were conducted in the N.P.L. 18 in x 14 in (0.46 m x ...

Pitching-moment derivatives have been measured, using a free-oscillation technique, for a series of thin tapered wings with both streamwise and raked tips. Wings of three aspect ratios (A.R. = 2.74, 2.00 and 1.25) were ...

The aerodynamic lift and moment derivatives for pitching oscillations in incompressible flow have been measured for two axis positions on (i) a clipped delta wing of aspect ratio 1.2, (ii) a complete delta wing of aspect ...
