Benefits of technology
The present invention provides a control system for jet propulsion boats that allows for easy and speedy return to a stable reference condition over time. This reference condition can be defined as the trim control member sets a balance between the forces acting on the boat to keep it stationary or moving in a specific way. The independent control of the deflector position allows for steering the boat while keeping it stable and balanced.
Problems solved by technology
The different customizations however mean that an initial reference position that is always identical and from which to start for any custom trim adjustments due to the contingent condition and specific characteristics of the boat's hull is lost.

Embodiment Construction
[0031]With reference to FIG. 1, the block diagram refers to a control system of jet propulsion boats according to the present invention.
[0032]Said system comprises in its more general form, at least one water jet propulsion unit, such as a turbine or the like;
[0033]a water jet ejection nozzle connected to the outlet of said water jet propulsion unit, which nozzle is oriented in such a way as to direct the water jet essentially at least in the longitudinal direction of the boat;
[0034]a jet deflector to change the flow direction of at least part of the jet of water leaving the nozzle with respect to the direction essentially parallel to the longitudinal axis of the boat and along a direction from the bow to the stern of the boat;
[0035]said deflector being controllable in such a way as to progressively adjust said part of the water jet deviated from the said direction essentially parallel to the longitudinal axis of the boat and along a direction from the bow to the stern of the boat, ...

A control system for jet-powered boats includes a water jet propulsion group; an ejection nozzle of the water jet oriented to direct the water jet at least in a longitudinal direction; a jet deflector changing flow direction of at least part of the water relative to the longitudinal axis of the boat, the deflector being controllable to progressively adjust the part of the diverted water jet and set a neutral thrust condition, in which the boat is stationary, thrusting forward with variable speed and thrusting backward with a predetermined or variable speed; a control member of the deflector position; a setting member of the deflector that adjusts the deflector to achieve a neutral thrust condition, the deflector being adapted for a predetermined and pre-set neutral thrust position; and a control member of the deflector in the preset position of neutral thrust, canceling any subsequent customization settings.
Description
FIELD OF THE INVENTION[0001]The present invention relates to a control system for jet propulsion boats comprising:[0002]at least one water jet propulsion unit, such as a turbine or the like;[0003]a water jet ejection nozzle connected to the outlet of said water jet propulsion unit, which nozzle is oriented in such a way as to direct the water jet essentially at least in the longitudinal direction of the boat;[0004]a jet deflector to change the flow direction of at least part of the water jet leaving the nozzle with respect to the direction essentially parallel to the longitudinal axis of the boat and along a direction from the bow to the stern of the boat;[0005]said deflector being controllable in such a way as to progressively vary said part of the water jet deviated from said direction essentially parallel to the longitudinal axis of the boat and along a direction from the bow to the stern of the boat, to determine a neutral thrust condition in which the boat is stationary, thrust...
