The German Aerospace Center (DLR) developed a toolbox, which is able to reflect the conceptual and preliminary design process of rotorcraft configuration. Such a toolbox is a valuable aid for the design engineer and can be used for the assessment of new technologies with regard to the overall configuration. This toolbox is currently extended to model novel rotorcraft configurations. Automated optimization procedures will be added in the future as well. This paper describes the toolbox layout and data management as well as the various individual tools developed at DLR in detail. Exemplary results of design tasks are given.
