Abstract:
1. A method to enable function of an electric or electronic mobile unit for vehicles flying or sailing on or in water that can electronically steer the vehicle by applying a piezo driven trim tab to rudders, ailerons, elevators and other position control surfaces changing the balance of the control surfaces and turning or changing the direction of the vehicle in motion by one or more of the following techniques: a. piezo snap to roll an axle or shaft bearing a means to propel the unit; b. piezo bending to enable steerage; c. piezo action to modify pitch or angle of attack of a component of a unit; d. piezo repeated flexing to pump liquid or air; e. piezo alternating and, as required, holding for the contact for a desired duration, to switch on or off the function of a circuit or circuit component; (f) permanently attaching the Piezo unit trim tab to the edge of the control surface furthest from the anchoring mechanism of the control surface of the vehicle or to the pilot controlled trim tab of the vehicle at its edge furthest from the anchoring or rotating mechanism, (g). wiring the Piezo unit to the electronic control such that when no power is applied, steerage is provided by the wheel or yoke or joystick, pedals, and motion of the yoke toward or away from the pilot, or other steering action; when positive charge is applied the Piezo control tabs moves one direction and when negative charge is applied, it moves the other direction, causing motion one way or the other counter the current position of the control surface, (h). activating the change of Piezo charge from none to positive or negative, or degrees thereof, can be included in the steerage mechanism, be operated via wheels or setting levers, or digitally operated by touchscreen or keyboard.
