VELOCITY POTENTIAL AND FORCES ON OSCILLATING SLENDER BODIES OF REVOLUTION IN SUPERSONIC FLOW EXPANDED TO THE FIFTH POWER OF THE FREQUENCY

Abstract

The linearized potential theory for supersonic flow about slender bodies of revolution undergoing harmonic oscillations is presented. The lift per unit length and the lift and moment coefficients on an arbitrary shape are expanded to the fifth power of the frequency. The theory is applied to a rigid cone undergoing harmonic translation and pitching motions. The results are compared with slender-body theory for the oscillating case and with Van Dyke's secondorder theory for the seady case. (Author)
