Wind Tunnel Investigation of an eVTOL Tiltrotor Test Bench

Recent developments of electric aircraft system for eVTOL aircraft demand a better understanding of unconventional propulsion integration for both vertical lift and forward flight. A new modular wind tunnel model on a reconfigurable test stand for eVTOL aircraft is presented in this paper. The model was developed at the Chair of Aerodynamics and Fluid Mechanics of the Technical University of Munich (TUM-AER) and includes capabilities for both time-averaged and time-resolved measurements of load and pressure data. This paper describes the model design and features and presents a selection of results of its first wind tunnel tests.     «
