VZLÚ is renovating the low speed wind tunnel

Infrastructure of VZLÚ wind tunnels is an essential part of basic and applied research and development in the field of aerodynamics and fluid mechanics. Experimental work in research projects is carried out for a number of industries: aviation, surface transportation (cars, buses, trains, etc.), power, construction and the environment. Due to its strategic importance, VZLÚ wind tunnels were included among large infrastructures for research, experimental development and innovation as facilities necessary for comprehensive research and development activities with high financial and technological demands. A document “Roadmap for Large Research, Development and Innovation Infrastructures in the Czech Republic” was approved by the Government on 15 March 2010 and wind tunnels are part of it.

An extensive renovation of the 3mLSWT low speed wind tunnel with a test section of 3m in diameter will take place by the end of 2016 within the Large Infrastructure Project (LM2011016), which is financed by the Ministry of Education, Youth and Sports. The old fan will be fully replaced by a new one, including the exchange of the stream tube. The new power unit will consist of one-stage axial fan with composite blades. The replacement of the power unit of the wind tunnel, reconstruction of the measuring cabin and complete replacement of the control system will take place at the beginning of 2014. A cooling system of test airflow will be installed in the next two years.
