空中加油是延长有人驾驶或无人驾驶飞机航程和续航时间的重要技术，在军事行动中每天有超过1000次空中加油飞行。用于空中加油的硬件需要根据所涉及的特定飞机和空速进行调整，加油机和接收机的排列表现明显不同。广泛的飞行试验费用高，对设备和人员也有危险，但实验室试验却因试验条件不具代表性而受到损害。本文介绍了第一个全尺寸的混合测试的空对空加油探头和锥管接触，物理加油硬件在实验室中耦合到一个数值模拟系统的其余部分，使用传感器和执行器。结果发现，力和运动轨迹忠实地捕捉特征锥响应动态在充分加油的情况下。严格的验证表明，该方法可以模拟在空中加油的情况下观察到的主要接触碰撞现象，具有较高的可重复性，包括有问题的设计关键的响应，如锥管倾斜和软管鞭打。由于装备一个加油机机队的成本约为5亿美元，该技术提供了一种重要的实验室测试手段，可以为设计迭代提供信息，减少开发时间和成本，并在飞行测试前提高安全性和可靠性。（减）
Air-to-air refueling is a vital technique for extending the range and endurance of manned or unmanned aircraft, with over 1000 refueling procedures flown per day in military operations. The hardware used for air-to-air refueling needs to be tailored to the specific aircraft and airspeeds involved, performing markedly different for permutations of tanker and receiver craft. Extensive flight testing is costly and risky to equipment and personnel, but laboratory testing is marred by unrepresentative test conditions. This Paper presents the first full-scale hybrid test of an air-to-air refueling probe and drogue contact, where physical refueling hardware in the laboratory is coupled to a numerical simulation of the remainder of the system using sensors and actuators. It is found that the forces and motion trajectories faithfully capture the characteristic drogue response dynamics in full refueling scenarios. Rigorous validation shows that the method can emulate the dominant contact-impact phenomena observed in air-to-air refueling scenarios with high repeatability, including problematic design-critical responses such as drogue tipping and hose whip. With the costs of equipping a tanker fleet standing around 500 million, the technique offers an important means of laboratory testing to inform design iterations, reducing development timescales and costs, as well as improving safety and reliability before flight testing.
