description	A drive unit for a rotary-wing aircraft has a first and second propeller, which rotates in the opposite direction to, and are axially spaced apart from, the first propeller. A first and second drive shaft are arranged coaxially with the first drive shaft, for the propellers, wherein the propellers are each rigid and mounted to be tiltable relative to the axis of rotation of their drive shafts. The tilt axis of each propeller extends in a plane perpendicular to the axis of rotation of the drive shafts and is oriented at an angle different from 90° relative to the longitudinal axis of the propeller. An electric drive module has at least two rotors which are coupled to one of the drive shafts, wherein the ratio of the diameter of the propellers to the axial distance between the propellers is between 4:1 and 12:1.
