Problems solved by technology

The problem with this is that the larger the slot, the less rigid the gearbox housing that accommodates multiple gears (e.g. planetary gears)

Embodiment Construction

[0063] refer to figure 1 , which shows a part of an aircraft wing 10 on which an aileron panel 12 is movably mounted. The aileron panel 12 is attached to the wing 10 by five mechanical linkage assemblies 14 spaced apart and arranged to allow articulation of the aileron 12 through a predetermined range of motion for controls the aerodynamic performance of the wing.

[0064] A first hydraulic servo actuator 16 and a second hydraulic servo actuator 18 are provided, which are arranged to move the aileron panel 12 relative to the wing 10 . Each servo actuator 16, 18 is powered by a respective hydraulic ram 24, 26, each hydraulic ram 24, 26 is supplied by a separate and independent hydraulic supply source (not shown).

[0065] In use, the hydraulic servo actuators 16, 18 are in active / standby control mode. In other words, the first hydraulic servo actuator 16 provides power to the aileron panel 12 for movement in response to commands from the flight control computer. During such...

Abstract

An aircraft control surface actuation assembly comprises a first electromechanical actuator assembly (44) driven by two independent motors (48, 50) for redundancy, with a damping assembly (46) provided to mitigate flutter.

Description

technical field [0001] The invention relates to an aircraft control surface drive assembly. More specifically, the invention relates to an electric drive assembly for the actuation of the main control surfaces of an aircraft, in particular the ailerons. Background technique [0002] Many aircraft use hydraulically powered control surface drive assemblies to move primary control surfaces such as ailerons. Typically two linear hydraulic servo actuators are provided per aileron surface (eg on the Airbus A320 (RTM)). Each linear hydraulic servo actuator includes a separate hydraulic ram to move the aileron surface. Movement of each cylinder is controlled by a valve module comprising servo valves. The servo-actuators create a separate load path from the wing structure to the ailerons to provide mechanical redundancy should one servo-actuator fail. [0003] Each linear hydraulic servo actuator is powered by an independent hydraulic supply to provide redundancy in the event of ...
