The control structure of the double-layer periodic pitch mechanism is very complex, and there is serious aerodynamic coupling, the cross-coupling of pitch and roll, the cross-coupling of pitch and lift, the cross-coupling of heading and lift, which become the main factors affecting the control quality of helicopters
I invented the controllable sliding 100-way transmission rotor, and proposed a new structure of double rotors, which can eliminate cross-coupling, but its transmission and control structure is more complicated

Abstract
The invention discloses a variable-pitch slippage circumferential dual-rotor wing. The variable-pitch slippage circumferential dual-rotor wing is used for a helicopter. The variable-pitch slippage circumferential dual-rotor wing comprises an input end, a splined hub, a one-way commutator, a pitching controller, a dual-way deflector, a steering supporting seat, an inner total pitch controller, an outer total pitch controller and two input ends; the input ends are connected with a power device; the one-way commutator comprises a same-direction shaft, a front bevel gear, a commutating bevel gear,a rear bevel gear and a coaxial reversing sleeve shaft; the dual-way deflector comprises a deflecting initiative inner bevel gear, a deflecting initiative outer bevel gear, a passive inner bevel gear, a passive outer bevel gear and an output sleeve shaft; the steering supporting seat comprises a fixed shaft bearing, a steering supporting frame, a movable shaft bearing, a worm wheel and a worm; the inner total pitch controller is connected with an inner total pitch control mechanism, and the outer total pitch controller is connected with an outer total pitch control mechanism; the splined huband the one-way commutator can be replaced with a dual-way side shaft sliding gear transmission mechanism; and control mechanisms of course control, lifting control, pitching control and transverse rolling control are basically independent with each other, and intersecting coupling is eliminated.
Description
technical field [0001] The invention relates to a transmission and control structure of a coaxial reversing double rotor, which is specifically composed of an input end, a spline hub, a single-way commutator, a pitch controller, a double-way deflection device, a steering support, and an inner collective pitch The transmission and control structure of the coaxial reversing dual-rotor consisting of the controller, the outer collective pitch controller, and two output ends is referred to as the variable-pitch sliding circumferential dual-rotor. Background technique [0002] Traditional dual-rotor helicopters adopt a double-layer periodic pitch control mechanism to achieve pitch control and roll control in the coaxial reverse dual-rotor transmission and control structure, and use dual-rotors to adjust the collective pitch to achieve heading control and synchronized collective pitch adjustment. To achieve lifting control. The control structure of the double-layer cyclical pitch ...
