Abstract
A light unmanned vertical take-off aircraft includes at least two fixed coplanar propulsion devices and at least one wing providing the lift for the drone. The coplanar propulsion devices and the wing are each laid out on the frame of the drone so that the plane of the profile chord line of the wing is substantially parallel to the plane defined by the two coplanar propulsion devices. The wing is pivotingly mobile relative to the frame along an axis parallel to the pitch axis of the drone. Also a method is provided for controlling orientation of a wing of a light unmanned vertical take-off aircraft as described here above. The method includes controlling an orientation of a wing as a function of at least one flight parameter of the aircraft.
