The cosmic nozzle is a channel with flowing hot gas in a system containing the following components: stars, a hydrostatic gaseous corona and a cavity with hot gas in the central part of the system. In the quasi one-dimension approximation, the following solution of the cosmic nozzle problem about cosmic nozzle was obtained Here (ν,ω, T, σ) are the dimensionless density, hydro dynamical velocity, temperature and cross section of the channel (η0, ω0, T0 σ0 are these values at ζ = 1), φ(ζ), πg(ζ) are the gravitational potential and the pressure in the gaseous corona. For a polytropic state equation of the gas in the gaseous corona
