The researches of the compressible plasma streams are presented in the modified quasi-steady plasma accelerator (QSPA) with a longitudinal magnetic field. The investigations are carried out within the framework of the one-fluid two-dimensional MHD-model of the axisymmetric plasma flows taking into account the finite conductivity of the medium. The features of the compressible streams on the output from the accelerator are revealed at the presence of a longitudinal field and the rotation of plasma.
