Wind Angular Rates

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

blockType: SubSystem

wind angular rates

Path in the library:

/Aerospace/Flight Parameters/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.
