The invention relates to a drive unit (12) for a rotorcraft (10), comprising a first propeller (22) and a second propeller (24), which is opposite the first propeller (22) and is axially spaced therefrom; the invention relates to a motor vehicle having a first drive shaft (26) for propellers (22, 24) and a second drive shaft (28) arranged coaxially with respect to the first drive shaft (26), the two propellers (22, 24) each being rigid and being mounted so as to be tiltable with respect to the axis of rotation of the drive shaft (26, 28) thereof. The tilt axis (K) of each propeller (22, 24) extends in a plane perpendicular to the axis of rotation of the drive shaft (26, 28) and is oriented at an angle (alpha) different from 90 degrees with respect to the longitudinal axis of the propeller (22, 24); and an electric drive module (30) with at least two rotors (36) which are coupled to each of the drive shafts (26, 28), the ratio of the diameter of the propellers (22, 24) to the axial distance between the propellers (22, 24) being between 4: 1 and 12: 1. The invention further relates to a rotorcraft (10) having a drive unit.

    本发明涉及一种用于旋翼机(10)的驱动单元(12),该驱动单元带有第一螺旋桨(22)和第二螺旋桨(24),第二螺旋桨与第一螺旋桨(22)反向并且与这个第一螺旋桨在轴向间隔开;带有用于螺旋桨(22、24)的第一驱动轴(26)和与第一驱动轴(26)同轴布置的第二驱动轴(28),其中,两个螺旋桨(22、24)分别是刚性的并且以能相对它们的驱动轴(26、28)的旋转轴线倾斜的方式被支承,每个螺旋桨(22、24)的倾斜轴线(K)在垂直于驱动轴(26、28)的旋转轴线的平面中延伸并且相对螺旋桨(22、24)的纵轴线成不同于90°的角(α)定向;并且带有电驱动模块(30),该驱动模块带有至少两个转子(36),转子与驱动轴(26、28)中的各一个驱动轴联接,其中,螺旋桨(22、24)的直径与螺旋桨(22、24)之间的轴向间距之比在4:1和12:1之间。此外,本发明还涉及一种带有驱动单元的旋翼机(10)。
