A VSTOL vehicle including a fuselage with two pairs of ducted rotors fully enclosed fore and aft of the fuselage respectively. The fuselage is aerodynamically shaped to generate lift in forward flight. All four ducts are configured such that their center axes are at angles tilted sufficiently forward from the vertical axis of the fuselage. Each ducted rotor is powered by one engine inside the duct behind the rotor. All four rotors and engine shafts rotates counterclockwise, generating substantial angular momentum for gyroscopic effect. Variable inlets of...
1. A VSTOL vehicle comprising:a fuselage shaped to develop aerodynamic lift in a horizontal flight;a plurality of ducts, rigidly and non-pivotably connected to said fuselage, which are positioned around center of mass of said vehicle, and whose center axes are at various fixed angles between, but substantially different from, said vehicle's vertical and longitudinal axes, such that full three dimensional attitude control can be achieved with torques produced by varying thrusts from said ducts; each said duct having inside a rotor which rotates about the ...
