Four types of flow in boundary-layer bleeds are discussed. Expressions are given for calculating the bleed internal drag for the various types using two alternative definitions of drag. Some general curves are plotted which ...

It has been shown experimentally at M = 2.58 that by removing a small quantity of air from the boundary layer through fine slits in the surface of a cone the transition Reynolds number can be increased from its natural ...

Methods of predicting shock pressure recovery and external drag at all mass flows have been developed for conical centre-body intakes at supersonic speeds. Comparison with wind-tunnel measurements shows that the method for ...

A brief review is made of simple theory for predicting the maximum lift-to-drag ratio for combinations of half-body and wing in supersonic flow, allowing for the so-called favourable interference. A comparison is given of ...
