VERTICAL-TAKE-OFF AERIAL VEHICLE WITH AEROFOIL-SHAPED INTEGRATED FUSELAGE AND WINGS
20230331379 · 2023-10-19 ·

VERTICAL TAKE-OFF AIR VEHICLE WITH BLENDED AIRFOIL FUSELAGE AND WINGS, object of this application, essentially consists of a fixed-wing aircraft comprised of an airfoil-shaped fuselage (02) with four wings (10) shaped by the same airfoil. Accordingly, the fuselage has an aerodynamic wing behavior contributing to lift and minimizing drag of the aircraft, which provides greater payload and greater flight autonomy, in addition to good flight safety due to gliding during the horizontal flight. On each wing tip there is installed a thruster (35) (electric, ducted fan, turbojet/fan, or even a propeller) capable of turning, tilting longitudinally relative to the shaft of the aircraft, independently, by means of a rotary control system of the thrusters (35). This system is comprised of a driveshaft (34) installed on each wing and its corresponding electric motor (30). The thrusters (35) are all identical in performance, weight, and size, as a form of minimizing manufacturing costs, but the thrusters of the wings to the left rotate in a counter direction to those of the wings to the right to stabilize (neutralize) the wing tip vortex effect and torque due to the rotary moments caused by the rotary set of each thruster. A single control center commands both the rotation of the thrusters and the traction thereof, providing total control of the aircraft by vectoring and rotation, without the need to use control surfaces. The present model is innovative in its design generated from an airfoil that blends the entire fuselage and wings, presenting a hybrid behavior, as it performs the tasks of a VTOL vehicle, of a helicopter, as well as a conventional fixed-wing aircraft, being versatile in its abilities of vertical landing/take-off, gliding, vertical flight forwards and backwards, and horizontal flight with maximum economy.
