The invention belongs to the field of aircraft aerial refueling systems, and particularly relates to a hydraulic drive linear telescopic aerial refueling device. According to the hydraulically-driven linear telescopic aerial oil receiving device, the oil receiving plug can be released and retracted under the driving of hydraulic pressure, the hydraulic cavity and the fuel oil cavity are independent from each other in the oil receiving device, the hydraulic cavity is arranged outside the fuel oil cavity, and the hydraulic cavity is arranged inside the fuel oil cavity according to the optimal design of the importance degree, the weight and the size. When air oil receiving is needed, the hydraulic system pressurizes the lower hydraulic cavity, and the oil receiving device is released under the action of hydraulic pressure; after oil receiving is finished, the hydraulic system pressurizes the upper hydraulic cavity, and the oil receiving device is withdrawn under the action of hydraulic pressure. The oil receiving plug can stretch out to a designated position for aerial oil receiving according to needs, the oil receiving plug is retracted into the aircraft body after oil receiving is finished, and aerodynamic noise caused by an oil receiving probe in the non-oil-receiving process and adverse effects on maneuverability of the aircraft can be reduced.
本申请属于飞机空中受油系统领域,特别涉及一种液压驱动直线伸缩式空中受油装置。本申请的液压驱动直线伸缩式空中受油装置,在液压力驱动下可实现受油插头的放出和收回,在受油装置内部,液压腔和燃油腔相互独立,按重要程度及重量、体积最优设计,燃油腔在外,液压腔在内。当需要空中受油时,液压系统向下液压腔充压,在液压力作用下,受油装置放出;当受油结束后,液压系统向上液压腔充压,在液压力作用下,受油装置收回。本申请可以实现按需将受油插头伸出到指定位置用于空中受油,受油结束后再将受油插头收回到机体内部,可以减少非受油过程中受油探管带来的气动噪声及对飞机机动性的不良影响。
