Abstract

The invention discloses a parallel reverse double-rotor helicopter transmission system. Under the normal working condition, an engine drives rotors to rotate through a speed reducer and drives a powergenerator to work through a differential mechanism; one part of generated electric energy is stored in an energy storage unit, and the other part of the generated electric energy is provided for other accessories; when the engine has a fault, an auxiliary power unit is changed into a power output mode, the energy storage unit provides the stored energy for a helicopter system as kinetic energy through the differential mechanism so as to keep the normality of the system and guarantee the stable flying of a helicopter; and therefore, problems of complicated structure, large mass and low reliability of an existing helicopter transmission system are solved. The parallel reverse double-rotor helicopter transmission system is used for transmission of rotor helicopters.

Description

technical field [0001] The invention relates to the field of power transmission of helicopters, in particular to a transmission system of side-by-side reverse double-rotor helicopters. Background technique [0002] Existing helicopter rotors generally include single-rotor with tail rotor and double-rotor. Single-rotor with tail rotor generally consumes a lot of power consumption in the take-off and hovering states, thereby increasing the power consumption of the whole machine, and The tail rotor rotates at a high speed and is disturbed by the countercurrent of the rotor, so the load is complicated, which is easy to cause noise and fatigue of structural parts. The two rotors of the dual-rotor helicopter are evenly stressed, and the reliability is higher. The dual-rotor type is divided into a side-by-side reverse dual-rotor helicopter and a dual-rotor coaxial helicopter. The side-by-side reverse dual-rotor helicopter is a relatively new type of helicopter. Rotors are installe...
