This module consists of a duct with transparent front andrear, between which is mounted a symmetrical aerofoil with a profile. The aerofoil may be accurately rotated to various angles of incidence (attack)to the air using the control and printed scale on the front of the duct. The aerofoil has 12 tapping points at various chord wise positions on its surface allowing the pressure to be measured at that point. The experiment mounts on the Air FlowBench contraction using toggle clamps. Each one of the tappings connects to themanometer (ancillary) via flexible tubes fitted with quick-release couplings. The tapping points are permanently connected to a manifold mounted on the duct showing the tappingposition and number for easy reference.
