The inclusion of the Increased Order Modeling (IOM) methodology in the industry has provided means to address problems where concentrated non-linear effects of any kind are important while increasing the speed of standard aeroelastic calculations. This type of problems could only be addressed before by linearization techniques or by dedicated separated tools to approach each type of non-linearity. This paper summarizes and details the following cases where this approach has been used at Airbus Defence & Space:

  • Non-linear Flight Control System (FCS) in gust response.
  • Non-linear boundary conditions in Aerial Refueling Boom System operation.
  • Control surface freeplay induced loads calculation due to Limit Cycle Oscillation (LCO).
  • Non-linear stiffness and rupture of elastomeric devices during a turbopropeller Blade Loss event.
  • Non-linear aerodynamic forces. Special attention is given to ease of implementation, robustness, calculation speed and upstream and downstream compatibility with the general dynamic loads calculation process.
