Development Of A New Medium Size Helicopter Wind Tunnel Model

Abstract

In the framework of the DLR guiding concept "The Rescue Helicopter 2030" a new medium size wind tunnel model was developed at DLR. The development of the new wind tunnel model was finished in 2024.In this paper background information of first ideas and final model design, of model scaling, and manufacturing of parts are given. The pre-testing of individual components and the complete model is described. Furthermore, insights for model instrumentation, load balance design, as well as for different data acquisition systems are included and preliminary results from first experiments and from two wind tunnel tests are presented.
