Description

Block Horizontal Wind Model converts the wind speed from a normal coordinate system to a bound one for the two-dimensional case using the formula:

Block Horizontal Wind Model it works in SI units.

Ports

Entrance

DCM is a pass:q transformation matrix[<br>] 3-by-3 matrix

A matrix of guiding cosines for converting the component vectors of a normal coordinate system into a connected one.

Data types: Float64

Vwind (m/s) — wind speed
3-by-1 vector

The components of the wind speed in the normal coordinate system, m/s. They are set as a vector.

Data types: Float64

θwind (deg) — wind direction
scalar

Wind direction, hail. The direction is calculated clockwise from the direction of the axis the normal coordinate system. The wind direction is the direction from which the wind blows.

Data types: Float64

Output

Vwind (m/s) — wind speed
3-by-1 vector

The components of the wind velocity in the associated coordinate system, m/s. They are set as a vector.
