Investigations Relating to the Extension of Laminar Flow by Means of Boundary-Layer Suction Through Slots

Abstract

Experimental investigations have been made of boundary-layer suction through slots as a means of increasing the extent of laminar flow on airfoil sections. The tests were directed, first, toward the determination of suitable types of suction slots and, second, toward the determination of the effectiveness of boundary-layer control as a means of increasing the extent of laminar flow in regions of favorable and unfavorable pressure gradient. The Reynolds number range of the tests extended up to 10.0 x 10(6). The investigations were made in 1939 and 1940.
