Landscape Wind Tunnel

Ландшафтная аэродинамическая труба

The Landscape Wind Tunnel is a special-purpose test facility for evaluation of wind loads on high-rise buildings, sport arenas, long-span bridges, river and sea port structures, drilling rigs, and unique constructions.

LWT facility is notable for its spacious test section and state-of-the-art outfit. The test section length is sufficient to enable simulation of the atmospheric boundary layer typical for the wind patterns on the building site under study, which significantly improves the accuracy of wind load determination.

The test section breadth of 11 m is wide enough to accommodate large-scale models with necessary details. It is particularly important in obtaining correct data for tall buildings and bridges when it is required to model surrounding landscape features and adjacent buildings.

The size of its test section and the modern toolkit make the Krylov’s Landscape Wind Tunnel one-of-a-kind in Russia and world’s top test facility in the field of aerodynamic studies for civil engineering and architecture design
