摘要
建立了加油软管-锥套系统的动态数学模型,并利用该模型进行空中加油对接过程模拟。在加油机尾流场中,根据牛顿运动定律,推导定长度软管-锥套系统的运动学方程和动力学方程;建立了变长度的软管-锥套模型来控制对接过程软管-锥套的稳定性,对软管-锥套动态特性进行了分析。在Matlab/Simulink仿真平台下搭建模型,在不同的飞行条件下对模型进行数字仿真验证。仿真结果与国内外公开试飞数据相吻合,验证了模型的正确性。所建模型可用于有人机空中加油训练模拟和无人机自主空中加油仿真等。
A dynamic mathematical model for hose-drogue refueling system is established and used for simulation of air refueling coupling.In the tanker＇s wake field,a set of equations is obtained to describe the motion and dynamics of the fixed length hose-drogue system.With the consideration of drogue-probe engagement,a variable length hose-drogue model is investigated.Dynamic analyses and control system design for air refueling hose-drogue systems during receiver-probe coupling are studied.Finally,a model is established based on Matlab/Simulink,numerical simulations for different flight conditions are carried out to evaluate the validity of the simulation model.Simulation results show good fitness compared to those simulation results available in the open literature.The simulation model could be used for pilot training in air refueling and simulation of UAV automated air refueling.
