Two particular stellar engines of class A and C, respectively, are described. When the Sun is the energy source, both of them provide practically the same thrust force. A simple dynamic model for Sun motion in the Galaxy is developed. It takes into account the (perturbation) thrust force provided by a stellar engine, which is superposed on the usual gravitational forces. Two different Galaxy gravitational potential models were used to describe Sun motion. The results obtained in both cases are in reasonably good agreement. Three simple strategies of changing the Sun trajectory are considered. For a single Sun revolution the maximum deviation from the usual orbit is of the order of 35
