Abstract

In order to realize self-turning technology of missile, in this paper, aerodynamic characteristics of slender body and rudder-fuse-lage body at extra-wide angle of attack were investigated by CFD technology, the process of missile turning was simulated by dynamic grid method, the range of aerodynamic force and the conditions of self-turning were evaluated, the phenomena of self-stabilization was revealed, the relationship between rudder control and turning process was found out, and the performance index of self-turning of missile was valida-ted. The numerical result provides a reference for system design and control design of missile which employs self-turning method to realize over-shoulder launch.

Key words： self-turning; extra-wide angle-of-attack; aerodynamic characteristics; dynamic grid
