One-metre low-speed wind tunnel (1MG)



One-metre low-speed wind tunnel (1MG)
The 1MG is primarily used to obtain measurement data for code validation of the aerodynamics of rotors, delta wings and boundary layers. Another purpose is the development of measurement techniques for aeroplane and helicopter aerodynamics.
By selecting different measuring sections, it is optimally configured for the respective measurement. This enables both stationary and transient measurements in the low-speed range. In addition, measurements can be carried out on moving airfoils and on rapidly rotating propellers or rotors. Transient velocity field measurements with frequencies in the kilohertz range are also possible. With a measuring section cross-section of 70 cm x 100 cm, wind speeds of up to 70 m/s are possible. A cross-section of up to 1.6 x 5.0 m is possible, whereby the available speed is reduced.
The large-scale research facilities of the German Aerospace Centre (DLR) offer a system for the automated evaluation of measurement data. This system is used to fulfil obligations within the framework of the aeronautics research programme (LuFo) and to conduct research in national (university education, Bachelor, Master, PhD) and international collaborations (for example with the NLR, ONERA and NASA).
