Abstract: In order to simulate the relative motion process of hose-drogue aerial refueling, explorations were made on the aerodynamic influence and flight approach strategy of the tanker and the receiver at close range. This paper proposed a motion model of hose refueling parachute, considering the tail wake vortex effect and the head wave effect. The simulation results show that the proposed model can accurately simulate the relative motion process of soft aerial refueling. Based on the large-scale ball screen flight training simulator of a certain type of aircraft, a soft hardware-in-the-loop simulation training system for aerial refueling was developed, the control method of the parachute component was designed in detail, and a set of visual simulation training plug-in for air refueling was developed using OpenGL language. 

Key words: hose-drogue aerial refueling, hardware-in-the-loop simulation, motion model, tail wake vortex effect, head wave effect
