The invention relates to a control method and a system of a helicopter rotor, which belongs to the technical field of helicopter operation. The control method is characterized in that the distance changing of a blade is realized by adopting an actuator positioned on the stinger of each propeller boss to drive a flap positioned at the rear edge of the blade, so as to realize the control of a rotorsystem. The system comprises a demountable flap (1) installed at rear edge of the blade, torque soft propeller bosses (14), an actuator (13) installed on the stinger of torque soft propeller bosses, a flap control mechanism (1) with one end being connected with actuator (13) and the other end thereof being connected with the flap (1), and a test control system (59). The control method and the system have the advantages that the screw piston of each blade can be independently controlled, the structure is simple, the weight is light, the controllability is good, and the reliability and the security are high.
Description
Helicopter rotor control method and system Technical field The invention relates to a helicopter rotor control method and system, belonging to the technical field of helicopter control. technical background Due to its unique flight characteristics, the helicopter can hover, vertically lift, and fly in any direction, making it unique in the large family of aircraft; the reason why the helicopter has this ability is mainly due to the rotor and its operation. system. The rotor and its control system are the key components of the helicopter, which have an important impact on the performance, control stability and flight safety of the helicopter. Existing helicopter generally realizes helicopter manipulation by indirectly manipulating the automatic tilter, and the basic principle of its work is shown in the introduction in the reference: (Bosi. Russian Helicopter founder--Yuriev. , 2001(3).5~6.). The automatic tilter is composed of a rotating ring and a non-rotating ring. T...
