In order to analyse flutter and gust, structural-mechanical simulation models of aircraft, aircraft components, and wind tunnel models must be created in such a way that essential statistical and dynamic properties can be recorded in a model. Within industry, the corresponding simulation models used for the entire aircraft, for instance, are known as Dynamic Master Models (DMM). As part of this process, global stiffness properties and mass parameters between nodes, which are present on the so-called load reference axis, are defined. Stiffness and mass models are presented separately.
The Institute of Aeroelasticity developed methods and procedures that resulted from issues identified in aeroelastic designs, which will enable the parametric generation of finite element models for dynamic analyses during the design process. Examples of where this can be used for relevant structure models include the iGREEN configuration and the structure model developed by the Institute for the FERMAT aeroelastic reference configuration.
Another focal point for the structural dynamic modelling of aircraft is the creation of landing gear models using multi-body simulations. These models are used for analysing landing and ground loads, as well as configuration studies.
