Results are presented of an experimental investigation of a rotating cylindric axial-flow grid of airfoils. Measurements of pressure distribution over the cylindric mid-section of the airfoil were obtained for several blade spacings and angular settings and under various operating conditions. These data were used to compute the lift characteristics. The possibility of supplementing pressure distribution measurements by wake traverses for the determination of profile drag was explored.
