Prediction of Normal Force, Pitching Moment, and Yawing Force on Bodies of Revolution at Angles of Attack up to 50 Degrees Using a Concentrated Vortex Flow-Field Model

Abstract

A method initially proposed by Bryson is extended to include asymmetric shedding. This method employs the impulsive flow analogy, and models each wake vortex using a single-point vortex. Free parameters inherent in the problem formulation are determined empirically. Normal force, pitching moment and yawing force coefficients are predicted for slender bodies with a nose fineness ratio greater than four and at a Mach number less than 0.9.
