Abstract

In an example, a compliant shaft enclosure support system for coupling to a shaft enclosure surrounding a shaft includes a bar having a first member slidably coupled to a second member. The bar is oriented along the pitch axis of the shaft. A first bar end of the bar is rotatably connected, around the roll axis and pitch axis of the shaft, to the shaft enclosure at a first connection. A second bar end of the bar is rotatably connected, around the roll axis and pitch axis, to the structure at a second connection. A link is rotatably connected, around the roll axis, at a first link end to the bar, at an intermediate location spaced from the first and second bar ends. The link is rotatably connected, around the pitch axis, at a second link end to the shaft enclosure at a third connection spaced from the first connection.
