0.9 m Wind Tunnel

National Research Council Canada, Ottawa, Ontario
What the facility does

Conducts low technology readiness level (TRL) research and performs detailed acoustic measurements of small-scale models for both the aerospace and automotive sector

Area(s) of Expertise

The 0.9 m wind tunnel was originally a 1/10th scale model of the National Research Council’s (NRC) 9 m wind tunnel and has for several decades served the industrial and research communities. The relatively small size of the facility enables it to be used for prototype development of capabilities that can be later integrated into NRC’s 9 m and 2 m x 3 m wind tunnels.

The 0.9 m wind tunnel circuit has been upgraded with acoustically treated turning vanes and by lining the plenum chamber with acoustic wedges, therefore reducing the background noise levels in the test section. This has transformed the tunnel into an excellent facility to perform detailed acoustic measurements of small-scale models for both the aerospace and automotive communities. In its current form, its wind speed ranges from 0 to 44 metres per second (m/s).

Working in our unique facility to test, validate and demonstrate your product provides a controlled environment to de-risk new and experimental products with reliable data that will be critical in the large-scale or commercial development of your product.
