Abstract
A reverse gate flow director comprising a flow director base plate of generally trapezoidal shape, having mounting holes, a leading edge and a trailing edge configured to minimize water turbulence, a flow director fin of generally rectangular shape, having a leading edge and a trailing edge configured to minimize water turbulence, to direct water output flow from a reverse gate exit port and configured for fitting inside a reverse gate exit port having a reverse gate deflection feature with mounting holes for fixedly attaching the flow director base plate thereto.
Claims20
A reverse gate flow director comprising:
- a flow director base plate of generally trapezoidal shape and mounting holes and having a mounting side and a water flow side;
- and
- a flow director base plate leading edge configured to minimize turbulence;
- and
- a dimpled surface across the flow side of the flow director base plate configured to create a boundary layer to minimize turbulence;
- and
- flow director splines along the length of the flow director base plate to direct jet pump water flow;
- and
- an angled base plate deflector configured to further direct jet pump water flow and having a dimpled surface to create a boundary layer to minimize turbulence and having splines along the water flow path to further direct water flow;
- and
- a flow director fin, having a leading edge to minimize turbulence beginning at the base plate leading edge, and a flow director fin having a trailing edge configured to minimize turbulence and terminating at the flow director base plate trailing edge, attached to the flow director base plate at an angle suitable to conform to the inside profile of the reverse gate and longitudinal to the flow director base plate edge and configured for fitting inside a jet boat reverse gate having a deflection feature;
- and
- an angled fin plate deflector configured to further direct jet pump water flow and having a dimpled surface to create a boundary layer to minimize turbulence and having splines along the jet pump water flow path to direct water flow.
A reverse gate flow director and distinct from a reverse gate comprising a base plate of generally trapezoidal shape having a first end for fixedly mounting to the reverse gate using a plurality of mounting bolts inserted through a plurality of mounting holes in the base plate and inserted through mounting holes in a reverse gate deflection feature, and further comprising a second end for holding a plurality of flow director fins abutted to a reverse gate exit port for directing water flow emitting from the reverse gate exit port beneath a stern-panel to improved jet boat reverse.
A reverse gate flow director and distinct from a reverse gate comprising a base plate having a first end for fixedly mounting to the reverse gate and a second end for holding a flow director tube to a reverse gate exit port for directing water flow emitting from the reverse gate exit port below a jet boat stern panel to enable improved reverse thrust.
