Analysis of the Axisymmetric Base-Pressure and Base-Temperature Problem with Supersonic Interacting Freestream-Nozzle Flows Based on the Flow Model of Korst, et al. Part III. A Computer Program and Representative Results for Cylindrical, Boattailed, or Flared Afterbodies

Abstract

The computer program presented and discussed in Part 1 of this report for analyzing the axisymmetric base-pressure and base-temperature problem with interacting supersonic free-stream and propulsive-nozzle flows was improved and generalized to include the analysis of an afterbody upstream of the base region. The afterbody geometries considered are: cylindrical, conical, parabolic, and tangent-ogive boattails and conical flares. The F0RTRAN IV computer-program listing, as well as detailed information on program development, organization, and usage, are included. Theoretical afterbody and base-pressure results are presented for parametric variations in afterbody geometry and flow variables. In addition, a limited comparison between theoretical and experimental conical- afterbody and base-pressure data is made.
