Modeling and Simulation of Transmedia Separation of Missile Ejected from Carrier with Adapter

doi:10.12382/bgxb.2022.0001

Abstract

Abstract:

In order to solve the problem of transmedia ejection separation of missile carrier with elastic adapter, based on the fractional areas-volume obstacle representation (FAVOUR) method, a multi-physical field coupling model for missile separation from the carrier near the free surface is established by using the RNG k-ε turbulence model and VOF function. The numerical simulation of the water entry process of the cylinder is carried out, and the calculated results are consistent with the experimental data, which verifies the rationality of the numerical model. The ejection and separation processes of the missile in trough and crest environments and at different initial pitch angles and initial velocities of water exit are numerically simulated, and the effects of initial pitch angle, water exit velocity and position above the water surface on the submarine-launched missile separated from the carrier are obtained. Considering the pitch angle of the missile at the moment of separation from the launch tube at the wave crest and trough positions, the optimal initial pitch angle is 3.24° based on the criterion that the pitch angle of the missile reaches 0° at the separation time at the wave trough position. The simulation method and results are of referential significance for engineering applications.
