Abstract

The present invention belongs to helicopter component design, and relates to a new configuration of an inside-shaft controlled automatic inclinator. The inside-shaft controlled automatic inclinator comprises a ring-type ball hinge type automatic inclinator (1) and a support platform assembly (2). According to the present invention, by selecting the automatic inclinator arranged in the shaft, the aerodynamic resistance of the helicopter can be reduced; with the inside-shaft controlled automatic inclinator, the internal space of the rotor shaft is completely utilized, such that the rotor structure space can be effectively used.

Description

[0001] Technical field: [0002] The invention belongs to the design of helicopter components, and relates to a new configuration of an automatic tilter operated in an axis. [0003] Background technique: [0004] The automatic tilter is an important part of the helicopter rotor system, and the collective pitch and periodic pitch change of the rotor are realized through this mechanism. In actual use, due to space constraints, it is necessary to arrange the control route of the automatic tilter within the rotor shaft. [0005] Most of the existing helicopter automatic tilters are arranged outside the axis, and the structure exposed outside the helicopter will inevitably increase the aerodynamic resistance of the helicopter. [0006] Invention content: [0007] In the present invention, the automatic tilter arranged in the shaft can reduce the aerodynamic resistance of the helicopter. At the same time, the automatic tilter operated in the shaft makes full use of the internal s...
