Rudder system for an aircraft

摘要

A rudder system for an aircraft includes a center box, a rudder and actuators, wherein the rudder is pivoted around a hinge line relative to the center box. The actuators are arranged at an acute angle relative to the hinge line, and connected with at least one pivoted pivot lever, wherein the pivot lever is fastened to the rudder by way of a first push rod. This provides considerably more installation space in a vertical stabilizer of an aircraft for a center box, so that the latter can comprise a distinctly smaller wall thickness than usual in prior art to absorb air load-induced torsion and bending stresses.

1. A rudder system for an aircraft, comprising:
a centre box; a rudder; and a plurality of actuators; wherein the rudder is pivoted around a hinge line relative to the centre box, wherein the actuators are arranged at an acute angle relative to the hinge line, and connected with at least one pivoted pivot lever, and wherein a first end of one of the plurality of actuators is connected by a first push rod to an aircraft structure to resemble a pendulum support, and a second end is configured to use the at least one pivot lever to move an end of a flange, the flange being pivotable in the aircraft structure and connected with the rudder, wherein the first end of the actuator is joined by a second push rod with a second pivot lever, the second pivot lever rotatably mounted on the aircraft structure, and moving the other end of the flange.
