Parallel to so-called exact calculation methods, which are used more and more frequently, other types of methods, both approximate and empirical, may prove to be useful in determining the total aerodynamic coefficients of missiles or supersonic vehicles. They have the advantage over exact methods of consuming little calculation time and are easily applicable to three-dimensional configurations. Their range of application is limited, on the other hand, and the choice of a method to be applied is at time difficult. A code based on these techniques for engineering calculations was developed in the United States in a number of versions (HABP and SHABP, Hypersonic and Supersonic-Hypersonic Arbitrary Body Program). After reviewing the methods used in the code and specifying their area of application, calculation results obtained with HABP and SHABP are presented and compared with the experience for different geometries, from simple forms of revolution to configurations of hypersonic vehicles or aircraft.
