Popis: A method based on the quasi-one-dimensional treatment of off-design supersonic jet flow is presented, together with the results of calculating the parameters of the jet on the interval of adaptation to the external conditions in the immediate vicinity of the nozzle exit section. On the jet formation interval the region of flow with strong discontinuities (shocks) is replaced by a surface of discontinuity. The mixing effect is taken into account by means of a concentrated mass flux in the section of discontinuity. It is shown that taking into account the real properties of the jet flow on the formation interval makes it possible considerably to improve the accuracy of a number of important flow parameters and to obtain a series of quantitative results that coincide with the experimental data.
