Abstract: In the process of hose-drogue aerial refueling, the maximum binding force between the drogue and probe can cause detachment of the docking point and fracture of the hose, and even lead to safety accidents. In this paper, to study the dynamic characteristics of the hose-drogue assembly in the oil transportation process, a multi-body dynamic model of the rigid-flexible-liquid coupling of the refueling system is established by using the ALE-ANCF fluid transportation pipeline model as well as the multi-body modeling method. To quantify the expected range of the binding force under the condition of parameter uncertainty, a fast uncertainty analysis method that combines the polynomial chaos method and the dynamic model is proposed. The expected range of docking constraint force is obtained when the flight speed, length of hose, and relative velocity of two aircraft are uncertain at different altitudes. Numerical simulation results show that when there is relative motion between the receiver and the tanker, the expected maximum pressure, shear force, and bending moment at the specific section of the probe greatly increase by 50%, 272%, and 772%, respectively.
