Abstract:In order to seek the optimal strategies of reducing the influence of receiver’s bow wave in a probe and drogue refueling system, the six degrees of freedom dynamic model of hose-cone under the influence of bow wave was established. The test data was used to verify steady-state and dynamic characteristics of the model. The characteristics of the hose under the influence of the bow wave when the receiver was approaching at different speeds were studied, the results show that the drogue moved upward with obvious cycle staggering, the movement amplitude got an enlargement as the docking velocities increased. And, the “Optimal initial offset of docking (OIOD)” was proposed. All the research show that: The probe was aimed to the OIOD 7m away from the steady drogue, and then, the receiver gone forward linearly, that can minimize the influence of the bow wave on the docking. Finally, it is proposed to “adjust and approach-wait-contact”, according to the engineering calculation results.
