FM 670 Subsonic Wind Tunnel
Open circuit, downstream fan type, for study of subsonic aerodynamics. Axial flow fan, aluminium tube flow straightener, wire mesh screen, contraction section, test section, diffuser. contraction and diffuser sections with high quality internal finish. Maximum aerodynamic efficiency and minimum turbulence. Adjustable fan speed by means of inverter. Four equally spaced static pressure taps connected to a manifold to minimize effects from a model. Air speed is indicated by inclined manometer. Models are mounted on two components load cell support with indicators for measurement of drag and lift. Model holder can be rotated for quick change on angle of attack, angular scale at the base of the holder. Test Section : 300x300x450mm. Mounted on mobile bench with castors. 220V, 50Hz.
