Особенности выстрела пороховой гидропушки

Constructive and physical features of a shot of a powder hydrocannon are considered. Advantages of this hydrocannon in comparison with the pneumatic hydrocannons, which use an energy of the piston are shown. Influence of a collimator on parameters of a jet of a powder hydrocannon is estimated. It is shown, that changing length of the collimator make it possible to influence in the certain limits in parameters of a jet and to increase efficiency of a shot of a powder hydrocannon.
