Air vehicles use a coordinate system of axes to help name important parameters used in the analysis of stability. All the axes run through the center of gravity (called the "CG"): • "X" or "x" axis runs from back to front along the body, called the Roll Axis. • "Y" or "y" axis runs left to right along the wing, called the Pitch Axis. WebDescription. The Direction Cosine Matrix Body to Wind block converts angle of attack and sideslip angles into a 3-by-3 direction cosine matrix (DCM). This direction cosine matrix is helpful for vector body axes to wind axes coordinate transformations. To transform the coordinates of a vector in body axes (ox 0, oy 0, oz 0) to a vector in wind axes (ox 2, oy …
