The theoretical model of the astrophysical accretion disk-jet structure formation model is studied. Hydrodynamic description is based on the generalization of the Beltrami disk-jet solution using the turbulent viscosity model. The properties of the disk-jet system are analyzed theoretically, when the system parameters depend on the two main characteristic parameters: turbulent viscosity parameter and Beltrami parameter. The value of turbulent viscosity defines the accretion velocity, while the Beltrami parameter controls the topological properties of the flow. Obtained results show that obtained solution can describe various classes of the disk-jet systems that can be realized at different spatial and energy scales.
