With our innovative mobile wind tunnel, we make rapid iterative development of airfoils possible. 96 high precision Bosch MEMS pressure sensors measure the airfoil lift. A traverseable wake rake measures the airfoil drag. The angle of attack is adjustable from +20° to -20° and measured with a high precision absolute encoder. This enables to test airfoils and iterate flap settings, turbulator locations or sealings rapidly at significantly lower cost than in a stationary wind tunnel.
