Abstract
A computational fluid dynamics based on the development of small perturbation theory for the solution of inviscid irrotational compressible fluid flow around flight vehicle configurations is described. The user-friendly feature of the code is illustrated by a guided weapon canard configuration for which are displayed computed pressure distributions on selected components. Five test cases including a simple wing shape and more complex guided weapon and aircraft configurations are presented, to demonstrate the capabilities and limitations of the code. Theoretical pressure, force and moment coefficients are compared to wind tunnel data obtained from various facilities including the DREV trisonic indraft wind tunnel. The results of the comparison show the capabilities of the code in the subsonic and supersonic speed regimes for simple and complex configurations at low incidences, and its limitations at transonic speeds and at high angles of attack.
