Abstract

The invention provides a coaxial double-propeller flight device. The coaxial double-propeller flight device comprises a bracket, a first shaft, a second shaft, a first propeller, a second propeller, adrive motor, a first drive wheel and a second drive wheel, wherein the first shaft is mounted on the bracket; the second shaft passes through the first shaft and is mounted on the bracket; the firstdriven wheel is connected to the first shaft; the second driven wheel is connected to the second shaft; the first propeller is connected to the first shaft; the second propeller is connected to the second shaft; the motor is connected to the first drive wheel and the second drive wheel; a first transmission device connects a first driven wheel to the first drive wheel; and a second transmission device connects a second driven wheel to the second drive wheel. Power is transmitted to the first propeller and the second propeller for rotation, so that ascending force is generated; besides, reverse-torsion and gyroscopic effect is reduced.

Description

technical field [0001] The present application relates to the field of aircraft, in particular to a coaxial double propeller flying device. Background technique [0002] At present, the domestic electric UAV system is basically in the form of a motor direct drive single propeller, which requires high motor torque. The current optimization idea of ​​the UAV power system has been to continuously optimize the motor structure in order to obtain higher efficiency, but the unit weight Bottlenecks have emerged in internal driving force and efficiency. In addition, single-propeller direct drive will have anti-torsion and gyroscopic effects. In actual use, it is necessary to demonstrate and test the tension line of the power system relative to the aircraft, in order to offset part of the anti-torsion through the adjustment of the tension line to obtain relative stability. However, due to the structural form, no adjustment can eliminate the gyro effect and can only offset part of the...
