Fundamental phenomena of separation and nonseparation flow pattern are considered, including the effect of positive interference of the jet with sub- and transonic external flow. The influence of the geometric parameters of the afterbody with a jet nozzle on their drag is shown; the criteria for the flow around it to be attached and the conditions for ensuring a minimum external drag are formulated. %8 2018-07-02
