摘　　要：为提高软式空中加油对接成功率,寻找降低头波影响的对接策略,建立受油机头波影响下的软管-锥套6自由度动力学模型,利用飞行试验数据验证模型的稳态特性和动态特性;研究对接阶段受油机以不同速度进近时,头波影响下的锥套运动特征,定义了“最佳对接起始偏差位置”的概念;研究表明:对接前,受油机在锥套后7 m以外时,将受油插头对准“最佳对接起始偏差位置”并直线向锥套靠近,能最大程度降低头波对对接的影响;依据工程计算结果,提出“调整靠近-等待-对接”的受油机对接进近策略。In order to seek the optimal strategies of reducing the influence of receiver’s bow wave in a probe and drogue refueling system,the six-degree freedom dynamic model of hose-cone under the influence of bow wave was established.The test data was used to verify steady-state and dynamic characteristics of the model.The characteristics of the hose under the influence of the bow wave when the receiver was approaching at different speeds were studied,and the optimal initial offset of docking(OIOD)was proposed.The research results show that the probe is aimed to the OIOD 7 m away from the steady drogue,the receiver goes forward linearly,which can minimize the influence of the bow wave on the docking.The strategy of adjusting then approaching-waiting-contacting is proposed according to the engineering calculation results.
