Abstract
In the present paper, we discuss a procedure for designing of cylindrical air inlets for high flight speeds with the use of V-shaped bodies for forming a plane flow with an initial oblique compression shock. In design regime, characteristics of such air inlets can be obtained by means of simple calculations performed in a broad range of governing parameters. The difference between the performance characteristics of a typical cylindrical inlet in design and off-design flow conditions was elucidated with the help of 3D numerical calculations.
