Unsteady local linearization solution for pitching bodies of revolution at freestream Mach numbers = 1 - Stability derivative analysis

Abstract

An account is prpvided of recent theoretical results for unsteady inviscid transonic flows about axisymmetric bodies. The unsteady local linearization solution is developed to calculate the unsteady pressure distributions, for sonic or near-sonic freestream flows, on the surface of several slender, pointed, axisymmetric bodies undergoing low-frequency oscillatory pitching motion. Results determined for static and dynamic stability derivatives exhibit good agreement with the limited experimental data available.
