Vertical-takeoff aircraft

Abstract

A vertical-takeoff aircraft with a wing. A first drive unit and a second drive unit are swivellably mounted on the wing. The first drive unit and the second drive unit are arranged on the wing at a distance from a wing-end of the wing. A first distance between the first drive unit and a longitudinal axis of the aircraft is approximately equal to a second distance between the second drive unit and the longitudinal axis of the aircraft. The first drive unit and the second drive unit are swivellable into a horizontal flying position and a vertical flying position. In the horizontal flying position the first drive unit is arranged above a wing surface and the second drive unit below the wing surface on the wing. In the vertical flying position the first drive unit and the second drive unit are arranged in an approximately horizontal plane. The first drive unit and the second drive unit each have a swivel arm, wherein the swivel arms are swivellably mounted on the wing.

DETAILED DESCRIPTION

(9) FIGS. 1 and 2 show schematic illustrations of vertical-takeoff aircraft 1 with a wing 3 arranged in each case on opposite sides of a fuselage 2. A first drive unit 4 and a second drive unit 5 are in each case arranged mounted pivotably on the wings 3. The first drive unit 4 and the second drive unit 5 each have a propeller 6 and a pivoting arm 7. The pivoting arms 7 are arranged pivotably on the wings 3, wherein a coupled pivoting movement of pivoting devices 8 arranged on the wings 3 is triggered and driven.

(10) The first drive unit 4 and the second drive unit 5 are arranged on the wings 3 in such a manner that a fuselage distance 9 of the drive units 4 and 5 from a longitudinal axis 10 of the vertical-takeoff aircraft 1 is smaller than a wing end distance 11 of the first drive unit 4 and of the second drive unit 5 from a wing axis 13 which runs through a wing end 12 and is parallel to the longitudinal axis 10.

(11) In FIG. 1, the first drive unit 4 and the second drive unit 5 are in the horizontal flying position, whereas, in FIG. 2, the first drive unit 4 and the second drive unit 5 are illustrated in the vertical flying position.

(12) FIG. 3 schematically illustrates a vertical-takeoff aircraft 1 without a tail unit with two wings 3 arranged on an upper side of a fuselage 2.

(13) FIG. 4a shows a schematically illustrated top view, and FIG. 4b a schematically illustrated front view, of a vertical-takeoff aircraft 1 with two rings 3 arranged on opposite sides of the fuselage 2, wherein two drive devices 14 are arranged on each of the wings 3. The drive devices 14 in each case have a first drive unit 4 and a second drive unit. 5 which are arranged mounted pivotably on the wings 3 by means of pivoting arms.

(14) The vertical-takeoff aircraft 1 is illustrated in the vertical flying phase in FIG. 4a. The drive units 4 and 5 are illustrated in the horizontal flying position in FIG. 4b.

(15) FIG. 5 schematically illustrates a pivoting device 8 with two drive pulleys 16 driven via a drive belt 15. The drive belt 15 is in each case fixed to the drive pulleys 10 at fixing points 17.
