Abstract
A transom flap can be deployed from the transom of an amphibious vehicle when the vessel is water borne. The transom flap is pivotally mounted and can be extended to extend into a position relatively acute to the transom of the vessel, the transom flap can be extended to impinge the propulsion jet of a jet propulsion drive system of the vessel or it can be deployed to extend out of the jet stream but at a less acute angle such that it will be helpful in trim adjustment of the vessel at speed.
Claims10
A transom flap for use on an amphibious vessel having a hull structure capable of planing comprising:
- a transom pivotally mounted to said vessel, said transom including a central cavity and a port through said central cavity of said transom;
- a transom flap pivotally attached to said transom capable of substantially closing said port through said central cavity and occupying said central cavity of said transom, said transom flap further being capable of deployment to a position extending outwardly from said hull structure to open said port;
- water jet propulsion system carried by said vessel, said system having water jet propulsion outlets directed to deliver water through said port of said central cavity of said transom;
- means to position said transom flap to impinge said water jet and deflect said water jet from its normal path, whereby said impingement of said water jet on said transom flap will cause an attitude change in said vessel controllable by the degree of incidence said transom flap presents to said water jet.
