An expression is derived on the basis of the method of differential locality hypothesis, and the structure of the third variation of roll moment coefficient is analysed, its complete composition is defined. Integral expressions of seven constituents of the third variation are obtained, physical interpretation of each is given.</p>Hypersonic flowsmall angles of attacksmall surface variationsroll momentmethod of differential locality hypothesisГиперзвуковое обтеканиемалые углы атакималые вариации поверхностимомент кренаметод ДГЛ
