The invention belongs to the technical field of aviation mechanical control, and relates to an aircraft fuel supply tank which comprises a main fuel tank and a partition frame using an aircraft body, a fuel supply tank front wall plate and a fuel supply tank rear wall plate are formed in the main fuel tank, the left wall plate and the right wall plate of the fuel supply tank are formed through the side walls of the main fuel tank, and a top plate is arranged at the top of the fuel supply tank to form an independent fuel supply tank body. The oil supply tank is divided into a left oil supply tank and a right oil supply tank, the left oil supply tank is communicated with the right oil supply tank, the left oil supply tank is communicated with the jet pump, one-way valves are arranged on the tops of the left oil supply tank and the right oil supply tank, and one-way valves are arranged on front wall plates and rear wall plates of the oil supply tanks. During design, the gravity center of the aircraft can be adjusted by setting the position of the oil supply tank; the fuel oil utilization rate of the long and flat oil tank is increased through the arrangement of the jet pump; the influence of fuel bubbles brought into the fuel tank after the jet pump is exposed out of the fuel surface is eliminated, and the working stability of an engine is improved; the function of oil supply in the airplane negative overload state is achieved; due to the oil transportation redundancy design after an injection power source is lost, the safety of the aircraft is guaranteed.
本发明属于航空机械控制技术领域,涉及一种飞机供油箱,包括主油箱,使用机体的隔框,在主油箱中形成供油箱前、后壁板,供油箱的左右壁板利用主油箱侧壁形成,供油箱的顶部设置顶板,形成独立的供油箱体,在供油箱中设置隔断,分出左、右供油箱两部分,左、右供油箱连通,所述的左供油箱与引射泵连通,所述的左、右供油箱顶部设置单向活门,供油箱前、后壁板上设置单向活门;本发明在设计时可以通过设置供油箱位置,调节飞机重心;引射泵布置增加了长扁油箱的燃油利用率;消除了引射泵在露出油面后带入油箱的燃油气泡的影响,提高了发动机工作稳定性;实现了飞机负过载状态供油的功能;具有失去喷射动力源后的输油余度设计,保证了飞机安全。
