The J2 Universal Tool-Kit – Dynamic Behaviour Analysis

From Steady State or Static Analyses, a lot of information can be gathered about the stability, behaviour and characteristics of the aircraft. However to investigate the aircraft further we need to look at dynamic behaviour.

Dynamic analysis uses a technique called response modelling. This is the technique of predicting the behaviour of an aircraft in response to various external inputs and atmospheric disturbances. This definition can be extended further to include the effect of stores release, engine out conditions, and configuration changes.
Response Modelling takes the accelerations from Equations of Motion defined earlier and numerically integrates these to provide revised velocities and positional information.
