The invention relates to the technical field of aircraft fuel systems, in particular to a multi-fuel-tank aircraft injection fuel delivery device and a fuel supply method thereof.The multi-fuel-tank aircraft injection fuel delivery device comprises a fuel supply tank, a main fuel tank, a left front fuel tank, a left rear fuel tank, a right front fuel tank, a right rear fuel tank, three injection pumps and a fuel booster pump; the jet pumps are arranged in the left rear oil tank, the right rear oil tank and the main oil tank respectively, dynamic pressure sources are provided for the jet pumps through the fuel booster pumps, and fuel is conveyed to the main oil tank from the left front oil tank, the left rear oil tank, the right front oil tank and the right rear oil tank respectively. An oil inlet port of the fuel booster pump is divided into a first oil supply pipe and a second oil supply pipe, and ports of the first oil supply pipe and the second oil supply pipe in the oil supply tank are arranged in a high-low manner; and an oil outlet port of the fuel booster pump is connected with the left engine and the right engine through a main oil supply pipe. By means of the oil conveying device and the oil conveying method thereof, the problems of high manufacturing cost, complex system arrangement and low reliability can be effectively solved.

    本发明涉及飞机燃油系统技术领域,特别是涉及一种多油箱飞行器引射输油装置及其供油方法,包括供油箱、主油箱、左前油箱、左后油箱、右前油箱、右后油箱、三个引射泵以及一个燃油增压泵;引射泵分别设置在左后油箱、右后油箱以及主油箱内,通过燃油增压泵为引射泵提供动压源,将燃油分别从左前油箱、左后油箱、右前油箱和右后油箱内输送至主油箱;燃油增压泵的进油端口被分流成第一供油管和第二供油管,第一供油管和第二供油管在供油箱内的端口呈一高一低设置;燃油增压泵的出油端口通过主供油管与左发动机、右发动机相连。通过本输油装置及其供油方法,能有效解决制造成本高、系统设置复杂和可靠性低的问题。
