This paper focuses on the application of dynamic allocation method in the aircraft with thrust vector. Firstly, the aircraft is modeled by the time scale separation principle. The control system is divided into two loops of fast loop and slow loop. The dynamic characteristics of the actuator are set to a first order model. Then, the process of solving the dynamic allocation method is analyzed, and the dynamic property as well as steady property of the algorithm is proved. Simulation is carried out on dynamic control allocation of the aircraft with thrust vector, with consideration of the dynamic property of actuators including traditional actuators and thrust vector actuators. The simulation results show that: 1)The using proportion of high frequency actuators is increased in the maneuvering process, and the speed of attitude angle command tracking is faster; and 2) The thrust vector actuators keep a lower deflection rate, which is conductive to prolong engine life. The dynamic control allocation method has achieved good effect in the application of the aircraft with thrust vector.
