Traditional depleted shutdown guidance approaches for solid launch vehicle have excessive attitude angle adjustment times, which lead to the difficulties of the control system design. A depleted shutdown guidance method with singular attitude angle adjustment was proposed. The required apparent velocity was used as a reference, the initial and final values of the rocket attitude angle were chosen by computing the apparent velocity, which is to be consumed. The attitude angle was changed from the initial value to the final value with a constant angle rate, and then the attitude was kept constant till depleted shutdown. The simulation results show that the proposed method with singular attitude angle adjustment satisfies the rocket’s terminal velocity constraint and that the percentage of consumed apparent velocity mode is more than 30%, and the singular attitude angle adjustment strategy can benefit the control system design.
