Active rudder pedal assembly for controlling aircraft and aircraft

Abstract

The present invention relates to an active rudder pedal assembly for controlling an aircraft and an aircraft comprising the same, the rudder pedal assembly comprising two rudder pedal units independent of each other The ground is respectively connected with the control unit of the aircraft, so that the two rudder pedal units can realize electrical coupling linkage through motor control, and each of the rudder pedal units includes: a first pedal pedal and a second pedal pedal , the first pedal and the second pedal can perform a translational movement along a direction substantially perpendicular to the pedal surface and a rotational movement around a rotation axis; the main shaft, the main shaft is respectively connected to the The first pedal and the second pedal are coupled; the first spring and the back drive motor coupled with the main shaft in parallel with each other, and the first spring and the back drive motor can be independently provided for each other. force feedback for translational motion.

Description

technical field [0001] The present invention relates to an active rudder pedal assembly for controlling an aircraft, such as an airplane, and an aircraft comprising such an active rudder pedal assembly. Background technique [0002] The fly-by-wire flight control system of the aircraft uses the rudder pedal assembly as the pilot's manipulation input to control the heading attitude of the aircraft; on the ground, it can also be used for deceleration and braking of the aircraft. The rudder pedal assembly converts the pilot's mechanical control into an electrical signal through a displacement sensor and outputs it to the flight control computer to realize aircraft yaw control. [0003] In the prior art, in order to realize the synchronization of main and co-pilot pedals, they need to be connected with a mechanical linkage to realize mechanical linkage, that is, one side pedal (such as the left side) of a pilot (such as the pilot who is driving) Pedals) are always in the same p...

AI Technical Summary

Problems solved by technology

[0005] 1) A large number of mechanical connecting rods, joint hinges, etc. are required, with large volume and weight, and complicated installation and adjustment;

[0006] 2) It needs to cross the floor of the cockpit: the pedals are located above the floor for the pilot to manipulate, and considering the limitation of the cockpit space, other parts need to be placed in the electronic equipment compartment under the floor, which is difficult to install and maintain;

[0007] 3) The rudder pedals of the pilot and co-pilot need to be connected through a mechanical linkage to achieve mechanical linkage. Once one side of the pedal is jammed, the pilot on the other side cannot control the aircraft through the pedals without disengaging the mechanism. yaw;

[0008] 4) Springs and dampers are used to provide a fixed force gradient and damping force, so the pilot cannot truly feel the position and load of the rudder surface

[0009] Accordingly, prior art aircraft rudder pedal assemblies are not entirely satisfactory
