In this review I discuss some aspects of the physics of collimated outflows emerging from accretion disks in connection with the modelling of Active Galactic Nuclei (AGN). Analytical and numerical studies of outflow propagation and instabilities are used to interpret structures detected at radio (non-thermal continuum radiation) and optical (continuum and emission line radiation) frequencies. The present situation is that good qualitative knowledge of the several dynamical effects which may shape AGN’s structures has already been reached; however the quantitative estimate of their relative importance and conditions of occurrence still awaits a better study of the nonlinear processes in astrophysical conditions and more observations to determine the values of the physical parameters.
