An Interior Ballistic Simulation of the Gas-steam Missile Ejection

An interior ballistic simulation of the canister launched missiles has been developed with the help of FLUENT. One of the special features of this simulation is the almost uniform acceleration which occurs 0.25s after startup and keeps the missile shockless during ejection. The calculation was done efficiently in FLUENT after setting all the required parameters. Several figures have been given to show the velocity and pressure of the flow field in the reservoir. The variations of the velocity and acceleration with time show that the simulation and the test data of the experiments are in good agreement with each other. This model can be used to analyze the similar launch procedures.
