Multi-shaft rotor aircraft and transmission mechanism thereof

Abstract

The invention belongs to the technology of rotor transmission of an aircraft, and particularly relates to a multi-shaft rotor aircraft and a transmission mechanism thereof. The multi-shaft rotor aircraft transmission mechanism comprises a reduction gear, a distribution gear and at least four groups of rotor transmission assemblies, wherein the reduction gear and the distribution gear are coaxial and synchronous; the reduction gear is connected with an external engine through a primary gear; each rotor transmission assembly comprises an acceleration gear, a first bevel gear, a second bevel gear, a transmission shaft, a third bevel gear and a fourth bevel gear which are sequentially meshed and connected; the acceleration gears and the distribution gear are meshed and connected, the fourth bevel gears and the rotor are coaxial and synchronous, and the rotor can be driven to rotate, so that the single engine can drive the multi-shaft rotor, a power system for an even number of rotors with more than four shafts can be expanded, and the rotating direction of each shaft can be configured randomly; therefore, the multi-axial rotor aircraft can have higher loading capacity and longer cruise duration than an electric multi-rotor aircraft.

Description

technical field [0001] The invention belongs to aircraft rotor transmission technology, in particular to a multi-axis rotor aircraft and its transmission mechanism. Background technique [0002] Existing multi-axis rotorcraft products use independent drive for each axis, and flight control is realized by controlling the speed of each axis drive motor. For example, the best-selling and popular quadrotor aerial photography aircraft on the market is driven independently by each axis, and the flight control is realized by controlling the drive motor of each axis. Since the speed of changing the motor speed is slower than the speed of changing the pitch, the power of the driving motor is limited and the response characteristics are difficult to improve. Using multiple motors to drive at the same time will consume more energy, thus limiting the performance of the multi-axis rotorcraft. Load capacity and battery life.
