Introduction of the AeroSUV - A New Generic SUV for Aerodynamic Research 2019-01-0646
Since the introduction of the DrivAer, an increasing amount of aerodynamic research and CAE method development activities is based on this detailed generic car body. Due to the Open Source nature of the model it has not only been adopted quickly by academia but also by several automotive OEMs and CAE software developers. The DrivAer has delivered high quality experimental data to permit validation of existing aerodynamic CAE capabilities and to accelerate the development of new more sophisticated numerical methods.
Within the last decades, the registration number of SUV, especially in Europe, has increased significantly. Among other things, this kind of vehicle is characterized by a high cross-sectional area, an increased ground clearance and large wheels. The DrivAer is not capable of depicting this vehicle category. Therefore, there is a demand for an expansion of this generic vehicle concept.
A new Open Source vehicle, the so-called AeroSUV is proposed to further expand the usability of the DrivAer concept. The structure of the AeroSUV is similar to the one of the DrivAer while representing a typical mid class SUV. The introduced vehicle geometry is developed with the aim to achieve a high number of carry over parts of the existing DrivAer. Furthermore, the vehicle is capable to carry the existing rear ends of the DrivAer. The geometry of the new AeroSUV will be made available over the ECARA website.
This paper focuses on the conceptual layout of the AeroSUV and will explain the design of the physical quarter scale test model. Furthermore, initial wind tunnel test data as well as CFD results will be presented.
