1. In a fluid vehicle of the type comprising at least one vertical wing in contact with the fluid for generating a forward motion, the improvement wherein said fluid vehicle also comprises a stabilizing torque system for generating jets transverse to the forward motion for the purpose of counterbalancing any capsizing effect.
2. The improved fluid vehicle of claim 1, wherein:
said vehicle comprises at least one horizontal wing, and
said stabilizing torque system is devised to generate said jets up and down to opposite ends of said at least one horizontal wing.
3. The improved fluid vehicle of claim 2, wherein said stabilizing torque system comprises an engine-driven pump for compressing the fluid and thus generating the requested jets.
4. The improved fluid vehicle of claim 3, wherein said fluid is air or water.
5. The improved fluid vehicle of claim 2, wherein:
said fluid is air;
said at least one horizontal wing is hollow and comprises a front wedge with at least one slot allowing fluid to enter into it; and
said stabilizing torque system comprises:
a windmill mounted within said at least one wing behind the slot, said windmill comprising a rotatable shaft in the form of a hollow cylinder extending parallel to the front edge of said at least one wing and a set of foils radially projecting from the hollow cylinder said foils being oriented in such a manner as to generate a lift effect when fluid enters into said at least one wing through the slot;
a propeller attached to at least one end of the hollow cylinder so as to be rotated by the same, said propeller being devised and positioned to pump the fluid entering within said at least one wing and to force said fluid either directly or via the hollow cylinder to nozzles provided on at least one of the opposite ends of said at least one wing so as to generate said up and down jets; and
a tilt-activated control valve to measure clockwise and counterclockwise motion of said at least one wing and to stabilize said motion by supplying the forced fluid to the nozzle(s) and thus producing the requested countertorque.
6. The improved fluid vehicle of claim 5, wherein said tilt activated control valve is devised to direct the fluid to the rear of the vehicle in order to form a back jet when no stabilization is required.
7. The improved fluid vehicle of claim 6, wherein said vehicle is an aircraft.
