The nature of flow in intakes with external boundary layer, at subsonic and supersonic speeds, is described. On the basis of a systematic series of wind-tunnel tests, a quantitative assessment is made of the loss or pressure ...

Summary. The nature of normal-shock and turbulent-boundary-layer interaction is described on the basis of an experiment involving two-dimensional flow, at M = 1.47, over a flat plate. Special attention is paid to the flow ...

In twin air-intake systems (i.e., a pair of intakes discharging into a common duct or chamber) in which the losses are affected by external boundary layers; asymmetry of flow between the two ducts occurs below a certain ...

The report is in two parts, following a general introduction. Part I describes wind-tunnel tests on (a) a series of models of annular entries, with and without propeller, in the 5-ft tunnel ; (b) a set of large circular ...
