Abstract

A supersonic rolling missile with two synchronous canard control surfaces is analyzed using an automated, inviscid. Cartesian method. Sequential-static and time-dependent dynamic simulations of the complete motion are computed for canard dither schedules for level flight, pitch, and yaw maneuvers. The dynamic simulations are compared directly against both high-resolution viscous simulations and relevant experimental data and are also utilized to compute dynamic stability derivatives. The results show that both the body roll rate and canard dither motion influence the roll-averaged forces and moments on the body. At the relatively low roll rates analyzed in the current work these dynamic effects are modest; however, the dynamic computations are effective in predicting the dynamic stability derivatives, which can be significant for highly maneuverable missiles.
