Patent attributes
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.
