Abstract : This paper describes work done during the last two years in an attempt to gain an understanding of, and to establish a capability for the use of, the Douglas Supersonic/Hypersonic Arbitrary Body Program (S/HABP). The program has a complex structure and offers a large variety of aerodynamic prediction methods to solve many different types of problem. Most of the features of the program have been used with some success. Aspects of the flowfield routines and viscous options, which could not be utilised correctly, are either under investigation, or updates to the programming are awaited. Some accurate predictions have been made using the inviscid pressure methods, which have been evaluated for a wide range of configurations, for Mach Numbers from 1.7 to 25.0 and from an incidence of -8 to 40 deg. The code has been seen to be highly flexible, but the accuracy of the results is user dependent. Relative to computational fluid dynamics codes, S/HABP geometries are easy to prepare and the code is cheap to run.
