Research on Simulation Method of Missile Adapter’s Separation Based on Combined Calculation

Abstract EN

In the background of a container-type vertical launch missile, the simulation method of adapter separation in different wind speeds is researched.

Based on force analysis of the adapters during their separation from the missile, the dynamic and kinematics equations of the adapter separation are established.

The adapter’s aerodynamic parameters at different attitudes getting from the numerical wind tunnel are chosen to be the input.

Through the dynamic simulation of the separation process of the adapters, the simulation results are in good agreement with the experimental data.

The trajectory and placement distribution of adapters are obtained during the analysis of force and motion stance at different wind speeds.

Then the relative distances between the adapter and missile or launch facility are determined.

At the same time, it can be estimated that the combined calculation will save about two-thirds of time compared with dynamic grid method computing, which provides a significant guidance for the simulation method of adapter separation.
