Fly-by-wire airplane side stick operating mechanism

Abstract

The invention belongs to the field of airplane control system design, and more specifically relates to a fly-by-wire airplane side stick operating mechanism. The fly-by-wire airplane side stick operating mechanism comprises a force feedback device. According to conventional fly-by-wire airplane side stick operating mechanisms, side stick operating is realized via design of a spring loading mechanism between moving parts and a housing, and through cooperation of a spacing mechanism. The disadvantages are that: the profile is long, the size is large, the weight is difficult to reduce, the tension compression symmetry is limited, and generation and broad width adjusting of bidirectional different force sense are impossible to realize. The invention provides a fly-by-wire airplane side stick operating force feedback device which is used for generation and adjusting of fly-by-wire airplane side stick operating artificial sense force. Forward rotating or backward rotating of a rocker arm rotating shaft driven by a pilot control handle are both capable of driving springs to stretch, the larger the rotating angle stroke, the higher the spring stretching degree, and the larger the force sense, so that generation of bidirectional artificial sense force is realize.

Description

technical field

[0001] The invention belongs to the field of aircraft control system design, and in particular relates to a fly-by-wire aircraft sidestick control mechanism, which includes a force feedback device. Background technique

[0002] With the continuous development of the fly-by-wire control system, the sidestick control system is not only light in weight and takes up less space in the cockpit, but also the pilot's control is easier and more accurate, which is conducive to improving the control quality of the aircraft. Therefore, the use of side sticks with smaller control force / displacement and smaller volume / weight to replace the conventional central stick / disc has become an option for the fly-by-wire aircraft control system, and whether the ideal control feeling force and displacement can be fed back to the pilot It will be the direct standard to test whether the quality of the side stick is good or not. The control feeling force of the sidestick of the current...
