Wind Tunnel Experiments of the CALLISTO VTVL Launcher in the TMK and HST Wind Tunnels [PDF]
CALLISTO is a demonstrator for a first stage of a reusable vertical take-off, vertical landing rocket and is developed and build within a collaboration of DLR, CNES and JAXA [1]. DLR is leading the aero science team [2] and is in charge of the aerodynamic and aerothermodynamic characterisation of the vehicle.

Scaling of wind turbine aerodynamics: wind tunnel experiments [PDF]
A small-scale wind turbine model was designed and manufactured to study its aerodynamic thrust force and the harvested flow energy. To provide a good understanding of the aerodynamics of the small-scale wind turbine at the low Reynolds number, the performance of three different types of blade airfoils was studied.

Measurements of dust deposition velocity in a wind-tunnel experiment [PDF]
In this study, we present the results of a wind-tunnel experiment on dust deposition. A new method is proposed to derive dust deposition velocity from PDA (particle dynamics analysis) particle-velocity and particle-size measurements.

Wind tunnel experiments: saltation is necessary for wind-packing [PDF]
ABSTRACTWind-packed snow in the form of slabs or crusts is an important part of alpine and polar snow covers. Yet, the formation process of such layers is poorly understood. For example, it remains unclear whether drifting snow is necessary for wind-packing or not.

About the suitability of different numerical methods to reproduce model wind turbine measurements in a wind tunnel with a high blockage ratio [PDF]
In the present paper, numerical and experimental investigations of a model wind turbine with a diameter of 3.0 m are described. The study has three objectives. The first one is the provision of validation data.
