| Abstract: | The aerodynamic characteristic of compressed air injection process is researched for hydraulic and balanceable underwater weapon launching system based on the theory of aerodynamics and thermody-namics.The dynamic behavior of high pressure air from pressure vessel to cylinder is analyzed,and the for-mula of air mass flow rate is obtained in a good approximation.The high pressure gas acoustic characteris-tic is discussed based on Lighthill equation.Then the influences of origin pressure of vessel,the volume ... |
