Suction-slot Ducting Design

摘要

To provide uniform suction through a narrow slot along the span of a wing, with the lowest possible losses, when the pump is'situated at the root of the wing.nModels of various design were tested and modified in the light of the results obtained. From these experiments, together with a qualitative analysis of the flow through the type of ducting proposed, specific recommendations have been formulated for the attainment of uniformity of suction combined with low power losses.
