Dynamic Pressure

R2026b

Compute dynamic pressure using velocity and air density

• 

Dynamic Pressure block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Aerospace Blockset / Flight Parameters

Description

The Dynamic Pressure block computes dynamic pressure.

Dynamic pressure is defined as:

$$\overline{q}=\frac{1}{2}\rho V^2,$$

where is air density and V is velocity.

Examples

Fly the De Havilland Beaver

Model the De Havilland Beaver using Simulink^® and Aerospace Blockset™ software.
