The test section can be fitted with two interchangeable variable incidence model carriers, one with a cylindrical section and the other with a low velocity sub-sonic aerofoil. The cylinder has a single static tapping which can be used to plot the pressure profile around the cylinder. Two Dimensional Wind Tunnel is designed for use with either Air Flow Bench or Fan Test Stand. The wind tunnel has a high aspect ratio clear acrylic test section 250 mm high and 65 mm deep. Pressures can be measured using Multitube Manometer or the Multiple Pressure transducer Module which provides 0-10 Volt analogue outputs for connection to a computer or data logging system. The aerofoil has 14 static pressure tappings allowing the pressure profile around the nose and along both the upper and lower cambered surfaces to be measured.
Experimental Capability:
Pressure profile around an aerofoil section and derivation of lift and drag forces and coefficients
Pressure profile around a transverse cylinder and derivation of drag force coefficient
Variation of lift and drag forces and coefficients, and liftdrag ratio with aerofoil incidence
Direct measurement of lift and drag on an aerofoil
Direct measurement of drag on a transverse cylinder.
