Abstract

The universal vehicle system is designed with a lifting body which is composed of a plurality of interconnected modules which are configured to form an aerodynamically viable contour of the lifting body which including a front central module, a rear module, and thrust vectoring modules displaceably connected to the front central module and operatively coupled to respective propulsive mechanisms. The thrust vectoring modules are controlled for dynamical displacement relative to the lifting body (in tilting and/or translating fashion) to direct and actuate the propulsive mechanism(s) as needed for safe and stable operation in various modes of operation and transitioning therebetween in air, water and terrain environments.

at least two of the plurality of cooperating modules of the aerodynamic contoured lifting body are displaceably connected to each other,
the plurality of cooperating modules comprise a thrust vectoring module and a propulsive mechanism operatively coupled to the thrust vectoring module,
the thrust vectoring module is dynamically controlled by the controller to affect positioning and actuation of the propulsive mechanism to attain a desired positioning of said vehicle and at least one of a plurality of modes of operation thereof, and
the thrust vectoring module is configured to support said universal vehicle in a resting position.

2. The universal vehicle of claim 1 , wherein the thrust vectoring module comprises a nacelle module carrying the propulsive mechanism thereon and rotatably displaceable about an axis extending sidewise the aerodynamic contoured lifting body.

3. The universal vehicle of claim 2 , wherein the lifting body further comprises a central front module and a rear module coupled to the central front module, and
wherein the thrust vectoring module comprises a nacelle module coupled displaceably to each side of the central front module for symmetric or asymmetric actuation of the propulsive mechanism in a controlled direction.

4. The universal vehicle of claim 3 , wherein the nacelle module has a length selected from a group consisting of: corresponding to a length of the central front modules, corresponding to a length of the lifting body, and corresponding to a length ranging between the length of the central front module and the length of the aerodynamic contoured lifting body.

5. The universal vehicle of claim 2 , wherein the propulsive mechanism is positioned at the front end of the nacelle module and is tiltably displaceable about an axis of the nacelle module.

6. The universal vehicle of claim 1 , further comprising at least one stabilizer module positioned in cooperation with a rear module, and having a vertical, horizontal, dihedral, or anhedral orientation relative thereto,
wherein the cooperation between the at least one stabilizer module and the rear module is selected from a group of rigidly fixed cooperation and deployable cooperation.
