Abstrakt: Possibilities of run duration increasing in a wind tunnel with a vacuum tank due to the use of a diffuser are analyzed. It has been shown experimentally and by calculation that the use of a standard diffuser at wind tunnel Transit-M increases the duration of the operating mode from 0.08 s to 0.24 s, i.e. 3.0 times. The design of a contoured diffuser in the form of an axisymmetric reversed isentropic nozzle has been proposed, which increases operating mode of the wind tunnel Transit-M at M = 6 from 0.08 s to 1.8 s, i.e. 22.5 times.
