Abstract
While in the conceptual design phase of launch vehicles, aerodynamic data is
often obtained through the use of a simple analytic program called APAS
(Aerodynamic Preliminary Analysis System). While suffering from an archaic
and temperamental interface, APAS yields results swiftly for simple geometries at
a variety of angles of attack and Mach numbers. The results from APAS are
compared to those obtained through the analysis of the same vehicle shape using a
sophisticated CFD program called GASP (General Aerodynamic Simulation
Program). The comparison is made on the forebody for the Stargazer Bantam
launch vehicle, which is based on a Hankey-wedge design. Significant
differences are noted and techniques to improve the accuracy of APAS output
data are suggested
