Incidence, Sideslip & Airspeed

Calculate incidence, sideslip, and airspeed

Library

Flight Parameters

Description

The Incidence, Sideslip & Airspeed block supports the 6DoF (Euler Angles) and 6DoF (Quaternion) models by calculating the angles between the velocity vector and the body, and also the total airspeed from the velocity components in the body-fixed coordinate frame.

α=atan(wu)

β=asin(vV)

V=u2+v2+w2

Inputs and Outputs

InputDimension TypeDescription

First

Three-element vector Contains the velocity of the body resolved into the body-fixed coordinate frame.

OutputDimension TypeDescription

First

 Contains the incidence angle in radians.

Second

 Contains the sideslip angle in radians.

Third

 Contains the airspeed of the body.

Examples

See Airframe in the aeroblk_HL20 model for an example of this block.

Introduced before R2006a
