A Linearized Solution for Time-Dependent Velocity Potentials Near Three-Dimensional Wings at Supersonic Speeds
Abstract
A source-distribution method is applied to derive a solution for the time-dependent surface velocity potential of thin finite wings at supersonic speeds. The solution is illustrated by evaluating the upwash over the tip of an arbitrary-plan-boundary wing having a supersonic and subsonic leading edge. The upwash then gives the effective sources of the flow field lying between the wing plan boundary and the foremost Mach waves, which are applied in the derivation of the wing-surface velocity potential. A simple example, the load distribution on a wing whose effective angle of attack is changing linearly with time, is included to illustrate the applications of the derived expressions.
