Research on strategy to decrease wind load of solid rocket with multiple-stage boosters

For solid rocket Hying in the endoatmosphere, the disturbance of wind field movement on ballistic trajectory cannot be neglected. This paper presents the dynamical model of solid rocket, selects a typical wind field model and analyzes the effects on ballistic characteristics in boost phase caused by wind field disturbance. And then a coefficient is introduced to reflect the degree of wind field disturbance and used as a basic reference to research the transmission mechanism of the effects on angle of attack and aerodynamic loads of the wind field disturbance. At last, this paper proposes a strategy to decrease wind load and the simulations show the efficiency of the proposed strategy.
