In this poster we present time-dependent numerical models of MHD jets driven by different magneto-centrifugal launching mechanisms. Our initial conditions for the simulations were calculated by solving for transfield force balance in jets driven by disks with different properties. The cross sections of density, velocity, pressure and magnetic field from these models are then injected into a computational grid. In this way we can study the long term evolution of jets produced by keplerian disks vs those produced by disks with enhanced rotation near the star due to a boundary layer. Using a high order accurate MHD code we show that the propagation characteristics of jets driven by different classes of rotators can be vary considerably in terms of shock dynamics, kinematics and morphology. Our results may provide a means for distinguishing between different models of jet launching and collimation.
