Unbalanced force balancing device for aircraft control system

Abstract

The invention discloses an unbalanced force balancing device for an aircraft control system. The unbalanced force balancing device is composed of a fan-shaped wheel (1), a rocker arm (2), a torque tube (3), a first support (4), a second support (5), and an adjustable balancing weight (6). A soft type control linkage (7) is connected with the fan-shaped wheel (1), and a hard type control linkage (8) is connected with the rocker arm (2). Through a balance weight, arrangement of a hard type pull rod in the control system and crosslinking of the control linkages with a human induction mechanism, acontrol augmentation mechanism, an automatic driving instrument and the like are counteracted, through introduced 'unbalanced force', the man-aircraft effect is improved, the control comfort is improved, and the flying quality is improved. The unbalanced force balancing device is simple in structure, convenient to mount and adjust and capable of shortening the adjustment period of a control system final assembly.

Description

technical field [0001] The invention relates to the technical field of aircraft flight control, in particular to a device for unbalanced force trimming in an aircraft control system. Background technique [0002] Aircraft control wiring systems are divided into soft control and hard control according to the transmission components used. The soft control wire system has the advantages of light weight, low cost, and convenient wire system layout, while the hard type control wire system has the advantages of good rigidity, good maintainability, and small system friction. Early aircraft mostly used soft controls. With the development of control systems, various types of aircraft currently use soft and hard controls. Most of the front-end controls use soft controls. The method is direct docking, that is, the connection between the sector wheel and the rocker arm. The "unbalanced force" introduced by the arrangement of hard tie rods in the existing control system and the cross-l...

AI Technical Summary

Problems solved by technology

The "unbalanced force" introduced by the arrangement of hard tie rods in the existing control system and the cross-linking of the control line system with the human-sensing mechanism, control stabilization, autopilot, etc., leads to inconsistencies in the left and right, front and rear control forces, especially the starting force. The actuation force in one direction is too large, and the actuation force often exceeds the standard when the control system is adjusted, which makes adjustment difficult and affects the production progress; in addition, the "unbalanced force" in the control system will make the ergonomics worse and affect the flight quality.
