REPORT ON AIR FLOW TESTS OF A NARROW COLLECTOR PASSAGE WITH EIGHT TRANSVERSE FEEDER SLOTSn(Applicable to 14OE1 Forward Shield Design Studies)

摘要

Previous analytical studies have indicated that a constant area collector passage with transverse feeder slots will, if the collector passage is narrow, suffer severe momentum losses in axial pressure distribution. These studies also predicted that the losses can be minimized by stepping the width of the collector at each feeder exit, and by turning the feeder exit parallel to the collector passage. These effects are verified by the results obtained in this report, for a simplified design employing eight transverse slots of uniform slot width, separated by slabs of uniform thickness.
