KALYAEVA Set out the effect of audiobitrate of the acceleration of the flow in supersonic nozzles, taking into account the implementation of polytropes currents in the presence of dissipative losses and heat transfer. Given the conditions that limit the ability to achieve supersonic speeds when the polytropic flow process. Violation of the principle of «impact reversal» for nonadiabatic flows is noted. The dependence of the critical Mach numbers, the pressure ratio for the cross section at the outlet of the channel, including at M = 1.0 on the atomicity of the gas, is shown. Keywords: the flow supersonic, the critical section, the pressure differential, locking, diplopoda, flow, tomnosti gas, dissipative losses. DOI: 10.25791/pfim.06.2019.1041 Contacts: - Pp. 03-09.
