Abstract
Discusses performance characteristics of an Eppler 387 aerofoil using both direct (force) and indirect (pressure) measurement at Re (60000 to 460000) in the Langley low turbulence pressure tunnel. Lift, drag and pitching moment data were obtained from two three-component internally mounted strain gauge balances, designed for small aerodynamic loads. Considers experimental data accuracy, and compares model measurements with pressure model results. Agreement is generally good, though at Reynolds numbers of 100000 or less, when laminar separation bubbles are present, the wake transverse method for drag determination is unreliable. (C.J.U.)
