This invention discloses a method for determining the separation time between stages containing thrust reversers and springs. This method can accurately determine the separation time between the booster and the main stage, providing support for separation safety and a reference for the main stage engine ignition time. The method mainly includes three parts: spring reverser time calculation, initial separation time calculation, and complete separation time calculation. First, aerodynamic simulation is used to calculate the aerodynamic forces in the initial state of the spring reverser and the fully extended state of the spring, thereby obtaining the spring reverser time through variable acceleration motion calculation. Then, using the fully extended spring state as the initial time point, the time it takes for the main stage and booster to reach a 5mm gap is calculated as the initial separation time. Subsequently, through coupled computational fluid dynamics and rigid body dynamics simulation, the separation trajectory of the booster under aerodynamic forces is obtained, thus obtaining the time for complete booster separation. Finally, the total separation time including thrust reversers and springs is obtained by summing the three time components.
