Abstract

The invention belongs to the technical field of design of an airplane control artificial feel system and relates to an airplane control artificial feel force producing device. The device is characterized by comprising a connecting rod (1), a first casing (2), a driving lever shaft (3), a torsional spring assembly (4), a driving lever gear (5), a second casing (6), a cover plate (7), a press plate(8) and the like. A pilot controls a control rod system in a certain axial direction of an airplane, a torsional spring in the torsional spring assembly (4) can produce elastic restoring force due totensioning no matter whether the connecting rod (1) is rotated clockwise or anticlockwise, so that torsion rotation feel is produced, the larger the torsion angle is, the larger the torsion is, the bidirectional airplane control feel force of the airplane pilot is realized, bidirectional artificial feel force of the pilot is realized by the aid of one torsional spring, and the device has small structure size, light weight, good force feel linearity, convenience in external connection and mounting, high reliability and long service life.

Description

technical field [0001] The invention belongs to the technical field of aircraft control artificial sense system design, and relates to an aircraft control artificial sense force generating device. Background technique [0002] The modern aircraft control system adopts power-assisted control power control. Since the booster bears the hinge moment of the control surface, the corresponding relationship between the pilot's control force and the flight state of the aircraft is cut off. The pilot cannot directly feel the load on the rudder surface. The artificial sensory force system is set up to provide control force simulation, so that the pilot can intuitively feel the state of the aircraft, and avoid the pilot's misoperation affecting the safety of the aircraft and the quality of flight control. [0003] The current aircraft control artificial sensory force is produced by a cylindrical compression spring load mechanism, which has a cylindrical long rod shape. Composed of rods...
