Wind tunnel tests were conducted on low aspect ratio wings in order to 1. Measure the oscillatory aerodynamic lift forces, pitching moments, and hinge moments acting on rectangular wings of aspect ratio 1 and 2, due to the harmonic vibration of flap or tab 2. Measure similar data due to static deflection of flap or tab 3. Measure wing pitching moment and flap hinge moment of the finite wings under zero lift conditions and 4. Compare these measured data with existing low aspect ratio theory.
