The hydrodynamic effects of a powerful thermal wind in active nuclei on the low-density gas component of a model galactic interstellar medium are investigated. The model ISM is based on properties of the Milky Way and other nearby "nonactive" galaxies. The wind is assumed to be highly supersonic with spherical symmetry and constant power. The wind power is varied from low-luminosity Seyfert galaxies to QSOs (1042 < Lw < 1046ergs s-1. The propagation of the wind into the low-density gas is studied using the Kompaneets approximation to a strong explosion in an exponential atmosphere. The near isobaricity of the shocked wind and ISM gases is used to determine the motion of the wind "bubble" for a variety of ISM gas distributions. The results show that for typical ISM pressures the extent of the wind can range from 1 to 10 kpc for wind powers of 1042 - 1046ergs s-1 in a time scale of less than 107yr.
