Summary
In a number of cases, surfaces of channel walls are distorted in the process of operation so that periodically reiterative dimples and convexities are formed. Thus, additional wave drag appears when such relief structures are flowed by the supersonic gas stream. There are theoretical data on relief surfaces wave drag only for some simplest forms of relief, but there are practically no experimental data. This work suggests the method which allows obtaining within the limits of linear approximation the exact formula for wave drag of channel walls with the arbitrary plate in the first and subsequent interference zones. By the example of sinusoidal relief it is demonstrated that pressure waves interference can lead to both increasing and decreasing of wave drag.
