CONTROL SURFACE OSCILLATORY COEFFICIENTS MEASURED ON LOW ASPECT-RATIO WINGS

Abstract

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.
