Abstract
There is provided a control stick module (10) comprising: a first shaft (100); a second shaft (110); a joint (140) connecting the first and second shafts; and a gimbal mechanism (120); wherein the joint is nested within the gimbal mechanism. The gimbal mechanism provides axes of rotation (201, 202) for the first shaft (100) and the joint provides axes of rotation (203, 204, 205) for the first shaft (100); and the axes of rotation (201, 202) provided by the gimbal mechanism intersect at a point corresponding to a point of intersection of the axes (203, 204, 205) provided by the joint.
Claims11
An aircraft control stick module comprising an assembly, the assembly comprising:
- a first shaft;
- a second shaft;
- a joint connecting the first and second shafts;
- and
- a gimbal mechanism,
- wherein the joint is nested within the gimbal mechanism and an origin of rotation of the joint is coincident with an origin of rotation of the gimbal mechanism;
- wherein the gimbal mechanism provides axes of rotation for the first shaft and the joint provides axes of rotation for the first shaft;
- wherein the axes of rotation provided by the gimbal mechanism and the axes of rotation provided by the joint intersect at the coincident origins of rotation;
- wherein the gimbal mechanism comprises a first gimbal disposed within and rotatably coupled to a second gimbal;
- wherein the second gimbal is disposed within and rotatably coupled to a fixed module frame;
- and
- wherein the assembly comprises sensors to measure and/or monitor the rotation of the first gimbal, the second gimbal, and the second shaft about a length of the second shaft.
