Abstract

The invention discloses a helicopter total distance control system which comprises a fixing shaft, a supporting base, a first fixing plate, a protective device and a reinforcing device, symmetrically-distributed control rods are arranged on the fixing shaft, symmetrically-distributed connecting rods are installed on the control rods, the connecting rods are connected with the first fixing plate. Symmetrically distributed connecting bases are arranged at the end of the fixing shaft, connectors are arranged at the bottoms of the connecting bases, the supporting base is located under the fixing shaft, penetrating holes allowing the connectors to penetrate through are formed in the surface of the supporting base, the protection device comprises fixing rings and fixing bolts, and the fixing rings are installed in the penetrating holes through the fixing bolts; the reinforcing device comprises a nut and an external thread; the helicopter total distance control system has the beneficial effects that the designed protective device is beneficial to installation of the fixing ring, and the through hole is protected through the fixing ring; and through the designed reinforcing device, the mounting stability of the fixed shaft is improved, and accurate operation of the control system is ensured.

Description

technical field [0001] The invention belongs to the technical field of helicopter collective pitch control, and in particular relates to a helicopter collective pitch control system. Background technique [0002] As one of the important systems of the helicopter, the control system is essentially to change the magnitude and direction of the rotor pulling force by changing the installation angle of the rotor (propeller) blades, so as to achieve the purpose of maintaining or changing the flight attitude of the helicopter. [0003] The existing helicopter collective pitch control system has the following deficiencies in use: [0004] The operation form is single, and the intention of transmitting the action is not clear; at the same time, the structure of the cooperative mechanism is not compact, and the structure of the parts is large, so that a large number of helicopters are occupied by the mechanical structure [0005] Furthermore, the perforations on the surface of the su...
