| Abstract: A gas powered fluid gun for propelling a stream or slug of a fluid at
high velocity toward a target. Recoil mitigation is provided 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. Examples of recoil mitigation devices
include a cone for making a conical fluid sheet, a device forming
multiple impinging streams of fluid, a cavitating venturi, one or more
spinning vanes, or an annular tangential entry/exit. |
