Description

Technical Field

[0001] The invention belongs to the field of aviation manufacturing technology, and in particular relates to a pedal shift and displacement detection device and an installation, disassembly and use method thereof. Background Art

[0002] The pedal is an important part of the aircraft flight control system. When the pedal is displaced without locking the rudder, the rudder will deflect; when the pedal is displaced with locking the rudder, the front wheel will deflect. In the ground test stage of the aircraft, in order to achieve the deflection of the rudder or the front wheel, human power is required to apply force to the pedal board through the legs and feet, and the pedal displacement is achieved by human power. When the pedal is displaced, according to the technical indicators, the pedal needs to be stabilized within a certain range of displacement (the pedal displacement is determined by installing a small plumb bob at the center of the pedal shaft and the projection displacement of the plumb bob), and the deflection of the rudder or the front wheel turning is observed and detected through this specific range of displacement. In the process of pedal displacement, due to the influence of the reverse force of the spring pull rod under the rudder, the pedal force of the person cannot be continuously and stably applied to the pedal board, resulting in instability of the displacement within a certain range, which in turn affects the angle displayed by the rudder or the front wheel turning. Therefore, when applying force to the pedal by human power to stabilize it to a certain displacement value, the operation method is difficult, time-consuming and labor-intensive, and the implementation effect is poor.
