Russian engineers working at the Central Aerohydrodynamic Institute (TsAGI) near Moscow have put one of their wind tunnels to work on a very interesting task - taming the behavior of the Kazakh People monument, a structure, apparently, set to be located in Kazakhstan's capital city of Astana,
The problem? Those danged wings...The press release from TsAGI describes it best:
"The 2,5m high model was tested in the Т1-2 WT under contract with CNIIPSK n.a. Melnikov. The monument was designed by the Karaganda Promstroyproekt Institute that contacted CNIIPSK in connection with the recorded unallowable range of oscillation.
The tests performed by the specialists of the Moscow TsAGI Complex identified the origin of the "sudden" braking oscillations: it was the bird sculpture that crowned the monument. The aerodynamic data obtained during the tests will be used for the mechanical oscillation damper design. Its proper location will also contribute to the aerodynamic stability of the "Kazakh people" monument.
