We present the solution of hydrodynamic equations of radiatively driven stellar wind with inclusion of the frictional force. Hydrodynamic equations are solved for absorbing ions (the first component) and for a passive plasma (the second component). We discuss the critical point condition for such wind. We show that friction does not lead to the separation of the two components of the wind of hot stars. However, friction decreases the outflow velocity.
