Theoretical results for shock-wave drag value estimation taking into consideration a surface relief exist only for some simple relief forms. Nearly all of them are obtained by solving of a boundary problem for a linear second-order partial differential equation derived by Blokhintsev. This boundary problem is solved in the paper analytically for a case of two-dimensional supersonic flow near reliefed surface. An arbitrary form of the relief is suggested. — informational site of MAI
