Abstract

The invention provides an airplane steering wheel force detecting device suitable for wire rope transmission. The airplane steering wheel force detecting device comprises a tension sensor, a pair of wire rope turn buckles, a pair of wire rope ends, a pair of first anti-loosening devices and a pair of second anti-loosening devices. The two wire rope turn buckles are arranged on the two sides of the tension sensor respectively, the two wire rope ends are arranged on the sides at the outer ends of the two wire rope turn buckles respectively, relative rotation between the tension sensor and the wire rope turn buckles is limited through the first anti-loosening devices, the tension sensor and the wire rope turn buckles are connected through threads, relative rotation between the wire rope turn buckles and the wire rope ends is limited through the second anti-loosening devices, and the wire rope turn buckles and the wire rope ends are connected through threads. The airplane steering wheel force detecting device is high in precision, low in cost and easy to implement.

Description

technical field [0001] The invention relates to a measuring device for measuring the control force of the steering wheel, which is used for measuring the control force of the aircraft control wheel driven by steel cables, and provides the required control force data for the evaluation of the control force or control quality of related types of aircraft, so as to Meet the needs of aircraft airworthiness certification. Background technique [0002] The control force of the aircraft steering wheel is an important factor to evaluate the stability characteristics of the aircraft, and an important indicator for the evaluation of aircraft flight test and airworthiness certification. However, the steering wheel is installed in the cockpit, and its space is narrow and its structure is complicated, so it is difficult to arrange larger test instruments. If the steering wheel itself is modified, it will easily cause inconvenience to the pilot, affect flight safety, and fail to achieve ...
