Calculation of Pressure Distributions on Two Axisymmetric Boattailed Configurations.

Abstract

Two published computer programs are used to calculate the pressure distributions on two axisymmetric boattailed configurations in inviscid, incompressible flow. Realistic results are obtained in the base region by extending the body surface to simulate the surface streamline separating from the base. The results show that a favourable pressure gradient is created by replacing the rear portion of a boattail by a cylindrical section, and conversely an adverse gradient on a boattail is strengthened by the presence of a large sting on wind-tunnel models.
