Direction Cosine Matrix to Wind Angles
Calculation of angles between the axes of the velocity and normal coordinate systems using the transformation matrix.
Description
Block Direction Cosine Matrix to Wind Angles calculates the angles between the axes of the velocity and normal coordinate systems: velocity roll angle , velocity pitch angle and velocity yaw angle .
The transformation matrix has the following form:
The angles are determined by the formulas:
The unit uses coordinate systems according to the international standard ISO 1151. |
Limitations
-
The values of the velocity pitch angle are in the range
[-90°, +90°]
. -
The values of the high-speed roll and yaw angles are in the range
[-180°, +180°]
