Abstract

The invention discloses an electronic direct-drive type stroke oar component for a hybrid-power helicopter and a helicopter with the electronic direct-drive type stroke oar component. The electronic direct-drive type stroke oar component comprises a stroke oar, a motor and an integrated type hybrid-power device, wherein the motor is connected with the stroke oar and is used for driving the stroke oar to rotate; the integrated type hybrid-power device comprises a power generator and an engine; the power generator comprises a rotor; the rotor is formed into a fly wheel of the engine; the power generator is connected with the motor so as to drive the motor to rotate. According to the electronic direct-drive type stroke oar component disclosed by the embodiment of the invention, the stroke oar is driven by the motor, and no extra speed reduction device is needed, so that a transmission structure of the stroke oar is effectively simplified, and the reliability is improved; meanwhile, the power generator is integrally arranged with the engine, and the rotor of the power generator is used as the fly wheel of the engine, the bottleneck that a conventional engine needs great power to generate power is solved, and the weight of the integrated hybrid-power device is effectively reduced.

Description

technical field [0001] The present invention relates to the field of aviation technology, and more particularly, relates to an electric direct-drive tail rotor assembly for a hybrid helicopter and a helicopter with the electric direct-drive tail rotor assembly. Background technique [0002] Main rotor with tail rotor is a common configuration for helicopters. Among them, on the one hand, the tail rotor is used to generate lateral force to balance the reaction torque of the main rotor, and on the other hand, it provides heading control. In related technologies, a common source of tail rotor power is that the engine outputs power to a reduction mechanism, and transmits power to the tail rotor through a mechanical transmission (such as a belt pulley, a drive shaft) to drive the tail rotor to rotate. [0003] Due to the large difference between the output shaft speed of the engine and the speed of the rotor and the tail rotor speed, a separate reducer must be designed for the r...
