MISSILE AERODYNAMICS AT HIGH ANGLES OF ATTACK - A PREDICTION CODE

A computer code MAHAA has been developed for estimating the aerodynami c characteristics of cruciform missile configurations at high angles o f attack (up to 30 deg), with arbitrary control deflections (+/-25 deg ) and nonzero roll angle (0 less than or equal to phi < 90 deg). The p rediction code is based on the equivalent-angle-of-attack technique. I t combines semiempirical methods, theoretical methods, and correlated databases. The code has been validated over a wide range of missile co nfigurations and night parameters, The overall capabilities of the cod e have been compared with nine other missile aeroprediction codes. The se studies have demonstrated the capability of the code for preliminar y design of missile configurations.
