Incidence, Sideslip, & Airspeed

Calculate incidence, sideslip, and airspeed

  • Library:
  • Aerospace Blockset / Flight Parameters

  • Incidence, Sideslip, & Airspeed block

Description

The Incidence, Sideslip, & Airspeed block calculates the angles between the velocity vector and the body, and also the total airspeed from the velocity components in the body-fixed coordinate frame. For the equations used in the calculation, see Algorithms.

Ports

Input

expand all

Velocity of the body, specified as a three-element vector, resolved into the body-fixed coordinate frame.

Data Types: double

Output

expand all

Incidence angle, returned as a scalar, in radians.

Data Types: double

Sideslip angle, returned as a scalar, in radians.

Data Types: double

Airspeed of the body, returned as a scalar.

Data Types: double

Algorithms

To calculate the angles between the velocity vector and the body, and the total airspeed, the block uses these equations:

α=atan(wu)

β=asin(vV)

V=u2+v2+w2
