9 m Wind Tunnel

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

Large wind tunnel (test section area 9m X 9m) which can accommodate a variety of surface vehicles, ground structures and aerospace models with air velocity up to 55m/s.

Areas of expertise

The 9 m wind tunnel is a large, state-of-the-art, high-security facility capable of accommodating a variety of surface vehicles, ground-based structures and aerospace models. Operated by experienced engineers and technicians, it is the facility of choice for several international original equipment manufacturers (OEMs). As the largest subsonic wind tunnel in Canada (and third largest in the world), it has the unique capability of testing full-scale surface transportation vehicles in order to provide ‘real-world’ results in a controlled experimental setting.

The NRC has recognized expertise in wind tunnel correction methodologies, pressure-sensitive paint technology, model deformation measurement capability and flow mapping. Our world-renowned team includes aerodynamicists, technicians and business experts that will support your research and technology development initiatives with professional services and industry know-how. Working in our unique facilities 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.
