Aerodynamics of Tactical Weapons to Mach Number 8 and Angle-of-Attack of 180 deg

Abstract : The NSWC Aeroprediction Code has been extensively applied to the prediction of static and dynamic aerodynamics of missile configurations. Major extensions have recently been made to the code to extend its capability to 0 less than or equal to M sub infinity less than or equal to 8 and 0 deg less than equal to alpha less than equal to 180 deg and also to improve the transonic inviscid body alone static aerodynamic predictions and the dynamic derivative predictions for all Mach numbers. The theoretical basis for the code extensions are outlined and previous methods are briefly reviewed. The code is evaluated through comparisons of computational examples with experiment for body alone, body-tail and body-tail-canard configurations. The speed and accuracy of the code are ideal for use in preliminary design. Examples of design applications to specific tactical weapon configurations as presented.
