Flight-Tests Measurements of Aileron Control Surface Behaviour at Supercritical Mach Numbers
Abstract
Aileron upfloat occurring at critical Mach because of loss of pressure recovery on upper surface aft of shock wave causes large increases in aileron hinge moment. Pressure distribution data showed critical effect of Mach number on hinge-moment magnitude. Aileron oscillations encountered ranging from mild "buzz" to motion causing aileron deformation showed agreement with wind-tunnel test results on partial span wing section. Spasmodic low-amplitude buzz warns of more severe oscillations at higher Mach.
