Trimming and Linearizing an Airframe

This example shows how to trim and linearize an airframe. We first need to find the

elevator deflection and the resulting trimmed body rate (q) that will generate a given

incidence value when the airframe is traveling at a set speed. Once we find the trim

condition, we can derive a linear model for the dynamics of the states around the trim

condition.

Fixed parameters :

Incidence (Theta)

Body attitude (U)

Position

Trimmed steady state parameters :

Elevator deflection (w)

Body rate (q)
