Submarine-launched Missile Launchers And Effluent Load Study

On the basis of deeply investigation of the submarine-based missile underwater launching technology, the paper mainly studies launching load and water-exit load of the submarine-based missile.In the paper, a numerical model of the interior flow of the submarine-based missile underwater launching is established. Simulation of the interior flow of submarine-based powerless missile underwater launching is performed by applying the finite volume method. By means of some simulation examples, the dynamic process of pressure load and acceleration impact load which occur in the process of missile launching is deeply studied. The dangerous position where the maximum load occurs and the time when it occurs are given. These results can provide technological reference to structure design, water tight design and launching security evaluation.The paper establish a water-exit movement numerical model. The water-exit movement of the submarine-based powerless missile which is horizontally or vertically launched is solved. The change trend of force and moment which are put on the missile is given. The effects of ocean current and wave that affect the missile is studied based on the front work.
