The propeller folding axis orientation is defined by two parameters, Azimuth and Elevation. In this tutorial, we demonstrate how the azimuth and elevation change the direction of the folding axis and provide useful views for observing the axis rotations. Refer to the sections below for additional details.
Azimuth and Elevation
The Azimuth and Elevation are defined according to the convention shown here in which the azimuthal plane of rotation is the XZ plane or, more specifically, the rotation is about the blade feather axis (+Y in this case) and the elevation is a direct, angular ascension from the azimuth. The propeller hinge rotation axis is the vector -a in this example.
The Azimuth and Elevation may be calculated from known directional components of the rotation vector a.
