Abstract
A SCAS module includes one or more SCAS actuators wherein each SCAS actuator comprises a piston arranged for linear motion within a hydraulic chamber in response to a flow of hydraulic fluid metered by a valve. The piston comprises a flexible rod or quill for providing a linear output along the first axis, the flexible rod or quill being mounted internally within an annular portion of the piston so that a space is defined around the flexible rod or quill. The flexible rod or quill is capable of deforming into the surrounding space in order to accommodate movement of the flexible rod or quill.
Claims13
A Stability and Control Augmentation System (“SCAS”) module comprising one or more SCAS actuators, the or each SCAS actuator comprising:
- a substantially cylindrical hydraulic chamber;
- a piston arranged for linear motion along a first axis of said hydraulic chamber;
- and
- a valve for controlling a flow of hydraulic fluid into the hydraulic chamber to cause said piston to move along said first axis;
- wherein said piston comprises a flexible rod or quill operatively connected to a first movable element and is arranged for providing a linear output to said first movable element along said first axis such that said linear output causes a movement of the first movable element in a direction parallel to said first axis,
- wherein said flexible rod or quill is mounted internally within an annular portion of said piston such that a space is defined between said flexible rod or quill and said annular portion in a second direction perpendicular to said first axis, and wherein said flexible rod or quill is configured for deforming into said space to accommodate displacement of said first movable element.
