US 2026/0035071 A1 · 4-PYLON EVTOL WIG

Abstract

An aerial and preferably marine vehicle intended to operate in its principal mode near the surface of water or land employing the Wing-in-Ground Effect (WIG) and capable to take-off and land vertically (VTOL) by means of thrust vectoring, which vehicle has a wing arranged at the lowermost part of the fuselage, propulsion units comprising four rotatable pylons extending transversely in pairs on both sides of the upper part of the fuselage, four elongated nacelles mounted on the outer tips of said pylons, which nacelles contain electric motors (E) and provided with propellers at their extremities, so that the rotation of the pylons results in turning the nacelles and thrust of propellers from substantially vertical, ensuring take-off and landing, to substantially horizontal providing a flight mode, retractable hydroskis for emergency landing on water, while said propulsion units and said wing are spaced apart vertically and horizontally and do not overlap.

An aerial and preferably marine vehicle intended to operate in its principal mode in the vicinity of surface of water or land employing the concept of the Wing-in-Ground Effect and being capable to take-off and land vertically, which vehicle comprises:

its center of gravity, the vertical longitudinal plane of symmetry and the lowermost basic horizontal plane,
a fuselage elongated in the direction of flight and substantially symmetrical relatively said vertical longitudinal plane,
a propulsion-free wing located at the lowermost bottom part of the fuselage and adjacent to said lowermost basic horizontal plane, so that two provided with flaps and ailerons half-planes of said wing extend outwardly on both sides of the fuselage and symmetrically relatively said plane of symmetry, while in the principal mode of operation said wing generates an aerodynamic lift with a resultant force located at about said center of gravity in horizontal projection, which aerodynamic lift supports the vehicle in its flight mode,
a substantially horizontal tail stabilizer with its symmetrical relatively said plane of symmetry half-planes provided with elevators, located at the lengthwise utmost aft and upper part of said fuselage, and at least one substantially vertical fin with rudder located at the lengthwise utmost aft part of said vehicle,
at least three retractable hydroskis built in the bottom part of the vehicle and intended for emergency landing on water, which hydroskis being elongated in the longitudinal direction protrude in the extended position below said lowermost basic horizontal plane, so that the rear end of each hydroski offsets further down from said lowermost basic horizontal plane than the front one,
while in order to ensure the vertical takeoff and landing, said vehicle is provided with a propulsion system consisting of four propulsion units with a turnable thrust vector, which system comprises:
four non-lift-generating rotatable pylons protruding transversely and substantially horizontally in pairs on both sides of the upper part of the fuselage and forming front and rear coaxial pairs of pylons with axes of rotation substantially normal to said vertical longitudinal plane of symmetry, so that the axis of rotation of the front pair is located in front, and the rear—behind said center of gravity of the vehicle lengthwise,
four nacelles containing electric motors and provided with propellers, which nacelles mounted on the outer tips of said four rotatable pylons with axes of rotation of said propellers being normal to the axes of rotation of said pylons, so that the rotation of the pylons leads to the rotation of the axes of the propellers in the planes being substantially parallel to said vertical longitudinal plane of symmetry, from a substantially horizontal position of the axes of the propellers corresponding the flight mode to a substantially vertical position corresponding vertical takeoff, hover, and landing modes of said vehicle,
whereas the two forward propulsion units are positioned in front of said wing and two aft propulsion units are positioned behind said wing lengthwise, so that the wing and the four propulsion units are separated and spaced vertically and horizontally, meaning that the projections of the four propulsion units on the transverse plane arrange higher than the projection of the wing, and the projections of the four propulsion units and the wing on the horizontal plane do not overlap.
