Description

Block Direction Cosine Matrix Body to Wind generates a matrix of guiding cosines for converting the component vectors of the associated coordinate system into a velocity one.

The transformation matrix has the form:

The block uses coordinate systems according to the international standard ISO 1151.

Ports

Entrance

ɑ β — angles determining the direction of the speed of the
2-by-1 vector

The angles that determine the direction of the aircraft’s speed, set as a vector. Vector elements:

— angle of attack, I’m glad.
— the angle of sliding, I’m glad.

Data types: Float64
