A pressurized, intermittent-flow wind tunnel capable of providing subsonic, transonic and supersonic flows over the range of Mach 0.1 to 4.25
The 1.5 m Trisonic Wind Tunnel has a demonstrated track record in performing aerodynamic assessment through a wide range of operational envelopes over subsonic through to high supersonic flow conditions. These test capabilities have been developed in a secure environment to deliver high-quality aerodynamic data of complete test articles and their sub components.
The facility offers three main test configurations to meet a number of test requirements: 3-dimensional configuration (typically used for missiles or small-scale aircraft models), half-model configuration (enables near full-scale Reynolds number for some Mach numbers), and 2-dimensional (a unique capability to allows testing of airfoils in nearly pure 2-dimensional flow).
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.
Our prominent competencies include stability and control testing, near full-scale Reynolds number testing for half-model business jets, and store separation and release testing for defense aircraft.
