Wind Angular Rates

Calculation of angular velocity with respect to the velocity coordinate system.

wind angular rates

Description

The Wind Angular Rates block calculates the angular velocity of the aircraft relative to the velocity coordinate system using the formula:

where

  • - is the vector of components of the aircraft angular velocity, rad/c;

  • - angle of attack, rad;

  • - glide angle, rad;

  • - is the rate of change of the angle of attack, rad/s;

  • - speed of change of the glide angle, rad/s.

Ports

Input

α β - angles of attack and glide
`vector 2 to 1

Angles of attack and slip given as a vector, rad.

Data types: Float64.

dα/dt dβ/dt - rates of change of angles of attack and glide
`vector 2 to 1

Rates of change of angles of attack and glide given as a vector, rad/s.

Data types: Float64.

ω is the angular velocity of the aircraft
`vector 3 by 1

Vector of components of the aircraft angular velocity , rad/c.

Elements of the vector:

  • Roll angular velocity .

  • Pitch angular velocity .

  • Yaw angular velocity .

The block uses angular velocity designations according to the international standard ISO 1151.

Data types: Float64.

Output

ωW - angular velocity of the aircraft relative to the velocity coordinate system
`vector 3 to 1

Vector of components of angular velocity of the aircraft relative to the velocity coordinate system , rad/c.

Data types: Float64.
