“…From the functional control structure in Figure 1, it is easy to derive the key objects of simulation validation: hose cone dynamic model, the reel mechanism control model, the tanker vortex field model, and the atmospheric turbulence model. Drawing on the relevant literature [6,18,19], the hose cone dynamic model adopts the multi-rigid body dynamic model based on the centralized parameter principle [6]; the reel mechanism control model considers the driving mechanism of the constant force spring; the tanker vortex field model employs the Hallock-Burnham model [19]; the atmospheric turbulence model uses the Dryden model [18]. On this basis, a 24-section hose cone was adopted.…”

“…Despite the fruitful results on the safety of aerial refueling, there is little report on the HWP, which was discovered in 2002 [4]. Some scholars have analyzed the hose-drogue model, and proposed effective suppression methods [5,6]. But there is a severe lack of reliable safety analysis for guidance.…”

“…By these methods, a complex system is treated as a complete body, and causal factors are analyzed from all levels, and the relationship between system components are clarified, shedding new lights on the safety analysis of complex systems [15][16][17]. The results of these methods could be validated by simulation with models like hose-drogue model [5] and auxiliary model [6,18,19].…”

This paper aims to identify the main cause of the hose whipping phenomenon (HWP) in air refueling, and come up with effective preventive measures. The system-theoretic accident model and process (STAMP), i.e., the system-theoretic process analysis (STPA), was adopted to evaluate the safety of air refueling. Then, the evaluation results were verified with a self-designed simulation validation model. The results show that the HWP is controlled by the docking speed, reel mechanism, and designed hose length; the swing range and tension change of the hose increased under inappropriate speed control; reel control could end the hazardous state of the hose within 50s after docking; the HWP occurred after the hose length was shortened from 22m to 14m. The research findings provide a reference for the prevention of the HWP.

“…Uncertainties in flight speeds, hose lengths, and relative velocities between the two aircraft can lead to either slack or over-elongation of the refueling hose. Excessive slack may give rise to the hose whipping phenomenon [13,14], potentially resulting in disengagement of the UAV from the tanker. Conversely, excessive extension of the hose can generate significant tension, directly leading to disconnection between the two aircraft.…”

This paper investigates the problem of finite-time tracking control for refueling formations under hose connection constraints subsequent to the docking of a receiving unmanned aerial vehicle (UAV) and a tanker in autonomous aerial refueling missions. The inclusion of hose connections not only imposes constraints to prevent disconnection but also introduces disturbances to the UAV. Initially, a model for the tension constraints at the hose-UAV connection point is first introduced, transforming complex hose constraints into relative state constraints between the UAV and the tanker. Meanwhile, a modified barrier function that incorporates the UAV's state and formation tracking errors is designed to deal with the decomposed hose constraints. Furthermore, an extended state observer is deployed to estimate external complex disturbances. Subsequently, leveraging dynamic surface control techniques, a finite-time control scheme is proposed to meet the dual requirements of preventing hose disconnection and achieving rapid convergence in the refueling formation. Compared to traditional hose constraint solutions, this scheme enhances the safety of refueling formation systems. Both theoretical proofs and simulation results substantiate the efficacy of the proposed control scheme.
