Coaxial twin-propeller twin-motor aerial vehicle
First Claim
1. A coaxial twin-propeller twin-motor aerial vehicle, comprising:
- an upper propeller,a lower propeller, andan aerial vehicle body,wherein the upper propeller and the lower propeller are disposed at the end of the aerial vehicle body, the upper propeller is located above the lower propeller, and a first motor and a second motor are provided inside the aerial vehicle body,the first motor is connected to the lower propeller through a first transmission shaft;
the second motor is located below the first motor and is connected to the upper propeller through a second transmission shaft, and the second transmission shaft passes through the first motor, the first transmission shaft and the lower propeller sequentially and then is connected to the upper propeller;
the second transmission shaft and the first transmission shaft are coaxial; and
the upper propeller and the lower propeller rotate at the same speed and in opposite directions under the drive of their individual motors;
wherein the coaxial twin-propeller twin-motor aerial vehicle further comprise a wing drive unit constituting part of the aerial vehicle body;
a ring-shaped wing extending out of the wing drive unit is provided at a central position of the wing drive unit, and the ring-shaped wing is movable horizontally under the drive of the wing drive unit;
wherein, when drag areas of the ring-shaped wing extending out of an outer circumference of the wing drive unit are the same in all directions, the aerial vehicle maintains a current flying posture; and
wherein, when the ring-shaped wing moves toward a certain direction to increase the drag area extending out of the wing drive unit in the certain direction, and contracts into the wing drive unit in an opposite direction to reduce the drag area in the opposite direction, the aerial vehicle changes said current flight posture.

Abstract
A coaxial twin-propeller twin-motor aerial vehicle comprises an upper propeller (1), a lower propeller (2) and an aerial vehicle body (3). A first motor (4) and a second motor (5) are disposed in the aerial vehicle body (3). The first motor (4) is connected to the lower propeller (2) through a first transmission shaft (42). The second motor (5) is disposed below the first motor (4) and is connected to the upper propeller (1) through a second transmission shaft (52). The second transmission shaft (52) passes through the first motor (4), the first transmission shaft (42), and the lower propeller (2) sequentially and then is connected to the upper propeller (1). The second transmission shaft (52) and the first transmission shaft (42) are coaxial. The upper propeller (1) and the lower propeller (2) rotate at the same speed and in opposite directions under the drive of their individual motors.
