Application of the Linearized Theory of Supersonic Flow to the Estimation of Control-Surface Characteristics

Abstract

Known conical-flow solutions of the linearized equation for the velocity potential in supersonic flow are applied to the calculation of the characteristics of control surfaces Complete solutions for the pressure distributions are obtained for control surfaces with hinge lines swept ahead of or behind the Mach line when the control-surface trailing edge is swept ahead of the Mach line. Useful approximate solutions of good accuracy are obtained when the trailing edge is swept behind the Mach line. Applications of the theory to the estimation of the hinge-moment and effectiveness characteristics of elevators and ailerons are presented.
