Comparison of Model Integration Approaches for Flexible Aircraft Flight Dynamics Modelling

Two approaches for the development of aircraft models integrating flight and airframe structural dynamics are compared. These models are intended for flight loads analysis and flight simulator application. The approaches combine available, agreed on flight mechanics and aeroelastic aircraft models from the respective engineering disciplines. The present work compares two methods, with different underlying assumptions, regarding accuracy, implementability, pre-processing and computing effort, as well as possibility to adapt the model components as a function of the flight condition.
