Abstract

A method of establishing dynamical models of axial symmetry missiles with complicated dynamical coupling was presented in this paper. The effects of vibration characteristics and flexibility deformation on the trajectory of flexible missiles were considered. First, according to traditional flight dynamics theory, the approach of establishing dynamical models of rigid missiles and flexible missiles with control force and aerodynamical force coupling was proposed. Second, the deformation equation of flexible missiles with control force, aerodynamical force and vibration coupling was derived based on Timoshenko beam theory. Finally, the effect of the flexible deformation of missiles to ballistic parameters was analyzed.
