The sleek aerodynamic form of the Thunderbolt's titanium and sapphire envelope has its roots in Maximilian busser's childhood passion for assembling model plane kits.

The new model is made out of eight panels, compared with the previous 14, and has special aerodynamic ridges on its surface.

It is shown the nonlinear aerodynamic model given by the article can accurately calculate aerodynamic responses of aircraft models in large amplitude forced oscillation tests at high angles of attack.
