Abstract :
In this paper, attitude control problem of carbin air-launching during separation stages between plane and vehicle by reaction control system (RCS) was studied. First analyzed movement under different separation conditions between launch rocket and plane, then determined launch vehicle flight status when RCS fired and designed rocket pitching program. On this basis, given the standard trajectory programs and RCS configuration. Using pulse width and pulse frequency modulation method, RCS thruster switch controller is designed. The simulation results show the correctness of RCS thruster configuration.
