Gas powered fluid gun with recoil mitigation

摘要

A gas powered fluid gun for propelling a stream or slug of a fluid at high velocity toward a target. Recoil mitigation is provided by a cavitating venturi that reduces or eliminates the associated recoil forces, with minimal or no backwash. By launching a quantity of water in the opposite direction, net momentum forces are reduced or eliminated.

主权项

1. A fluid gun system for propelling a stream or slug of a fluid at a high velocity towards a target, the system comprising:
a gun barrel having a central bore, an open front end, an open rear end, a side, and an opening through the side for conveying fluid into the central bore; a fluid storage tank for containing a pressurized fluid; a fluid supply line for supplying pressurized fluid from the fluid storage tank to the opening in the side of the gun barrel; a fluid ejection valve disposed in the fluid supply line, for controlling flow of the pressurized fluid from the fluid storage tank to the opening in the side of the gun barrel; and a device attached to the open rear end that changes the pressure of fluid exiting the open rear end; wherein the device comprises a cavitating venturi nozzle for flash vaporizing the rearward-moving stream.
