[Abstract]:Based on the vertical launching technology of submersible vehicle, the vertical launch of underwater vehicle will be a trend of weapon development in the future. In this paper, a three-dimensional numerical simulation is used to study the continuous vertical launch of a submarine-launched vehicle, with emphasis on the effects of different launch space intervals and the characteristics of the transverse flow, the hydrodynamic characteristics and the moving characteristics of the vehicle. The "water hammer" effect of the ship after it is out of the cylinder is analyzed. The main research contents are as follows: based on the homogeneous multiphase flow model, a three-dimensional numerical simulation method for continuous vertical launch of a submarine-launched vehicle is established. Numerical simulation of continuous vertical launch of underwater vehicle is completed. The flow field characteristics, hydrodynamic characteristics and moving characteristics of the two launch vehicles are analyzed, and the motion process of the outgoing cylinder and the underwater navigation is numerically simulated under different launch space intervals. The flow field characteristics, hydrodynamic characteristics and the motion characteristics of the vehicle under different launch space intervals are analyzed, and the effect of the initial launch vehicle on the pitching motion of the secondary launch vehicle is studied. Considering the transverse flow, the influence of the transverse flow on the flow field after the ship exit, the trajectory of the ship out of the cylinder and the mechanical characteristics of the vehicle are analyzed. The effect of "water hammer" produced after the exiting of the vessel is studied and analyzed, and the variation law of the pressure inside and around the launcher is obtained. The variation of pressure oscillation at the nozzle and the relationship between the pressure variation at the bottom of the barrel and the mass flow rate of the water flowing into the launching tube are analyzed.
