    Abstract
  • To investigate the water jet noise of high-speed underwater weapon, we design a high-speed water jet device for experiment,and establish four models,including gas state model of supplemental cylinder,gas flow model of connecting pipe,gas state model of pneumatic-hydraulic cylinder, and hydrodynamic model of nozzle.We obtain the change rules of pressure from gas cylinder and pneumatic-hydraulic cylinder and water jet speed by numerical simulation.The results show that the device can keep stable high-speed water jet at nozzle within a certain period, and satisfy the demand of the experiment.
