2D Airfoil Measurements

Four independent measurements systems – pressure taps on the airfoil surface, wall pressures, force balances, and a wake rake – are combined to one redundant measurement system which provides reliable measurement data on lift, drag and pitching moment on 2D airfoil sections.

Airfoils with a span of 1250mm are mounted vertically between two turntables. A turbulence intensity <0.35% and wind speeds of up to 100 m/s allow testing at up to Re=6E6. The measurement of 360 polars is even possible at Re over 1E6.

Aerodynamic, aeroacoustic and thermographic measurements for detecting the laminar-turbulent transition can be performed simultaneously, saving our customers’ valuable time and money.
