In air combat tactics and efficacy researching, it is often first to define the expected aircraft's maneuvers, then the dynamics parameters related to the maneuvers need to be determined. Aimed at this problem, the paper discusses the air combat maneuver modeling which has accurate dynamics property and also suits the need of air combat research. The simplified dynamic model is set up, in which the imports are aircraft's load vectors and engine's state or aircraft's velocity are taken as the imports of maneuverable action, these imports have close connection with air combat maneuver description and well transform the intension of pilot into the maneuver's control input. The simulation results show that the model is high in simulation precision，simple, practical and suitable for air combat tactics simulation.
