Numerical Simulation of Hose Whip Phenomenon in Hose-Drogue Aerial Refueling

The hose whipping phenomenon in hose- drogue aerial refueling was simulated based on a high- efficient neighbor- to- neighbor algorithm.The Osher scheme and S- A turbulence model are employed to solve the compressible Navier- Stokes equations,and the hose is discretized into a series of ball hinges linked by massless rigid links which form a multi- body system,the kinematical and dynamic equations are derived for the system.The numerical model is used to simulate hose- drogue system dynamics in multiple conditions,the results show a good correlation with previously reported flight- test data in open literature and the application of neighbor- to- neighbor algorithm saves a lot of computation time.Results of this study have certain guiding significance for the drogue-probe aerial refueling.
