The invention discloses an uncontrolled thrust augmentation oil supply structure suitable for a thrust augmentation supersonic aircraft and the aircraft, and aims at optimizing fuel oil gravity center management of the aircraft in the supersonic speed and subsonic speed states. The structure comprises a thrust augmentation oil tank, a main oil supply tank and an engine, the thrust augmentation oil tank is made of flexible materials and located in front of a fuselage, the gravity center moves backwards through fuel oil consumption, the static stability of supersonic flight is reduced, and the flight performance is improved. The main fuel supply tank is located near the gravity center of the fuselage and supplies fuel to the engine through the pressurizing pipe and the main fuel supply pipe. The thrust augmentation oil tank and the main oil supply tank can complement each other, the dead fuel phenomenon is avoided, and the fuel utilization rate is increased. The uncontrolled design without special control parts simplifies the system structure, improves the reliability and reduces the manufacturing cost and weight. According to the method, gravity center optimization and efficient fuel oil management of the aircraft in different flight states are achieved, the flight performance and the task execution capacity are enhanced, and the method has remarkable practicability and economical efficiency.

    本发明公开了一种适用于加力超音速飞行器的无控式加力供油结构及飞行器,旨在优化飞行器在超音速和亚音速状态下的燃油重心管理。该结构包括加力油箱、主供油箱和发动机,加力油箱采用柔性材料制成,位于机身前方,通过燃油消耗实现重心后移,降低超音速飞行的静稳定度,提高飞行性能。主供油箱位于机身重心附近,通过增压管和主供油管向发动机提供燃油。加力油箱与主供油箱间可相互补充,避免燃油死油现象,提高燃油利用率。无需特殊控制部件的无控式设计简化了系统结构,提高了可靠性并降低了制造成本和重量。该发明实现了飞行器在不同飞行状态下的重心优化和高效燃油管理,增强了飞行性能和任务执行能力,具有显著的实用性和经济性。
