The invention provides a fuel oil system of a light sports aircraft, which relates to the technical field of aircraft fuel oil supply equipment and comprises a main oil tank, an auxiliary oil tank, a first fuel oil pipe, a second fuel oil pipe, a third fuel oil pipe, a fourth fuel oil pipe, a first electric fuel oil pump, a second electric fuel oil pump and a fuel oil valve. The two ends of the first fuel pipe are connected to the auxiliary fuel tank and the first electric fuel pump respectively, the two ends of the second fuel pipe are connected to the first electric fuel pump and the main fuel tank respectively, the two ends of the third fuel pipe are connected to the main fuel tank and the fuel valve respectively, one end of the fourth fuel pipe is connected to the fuel valve, and the other end of the fourth fuel pipe is used for being connected with an engine. And the second electric fuel pump is arranged on the fourth fuel pipe. In the flying process of an airplane, when the main oil tank gives an oil quantity alarm, the auxiliary oil tank can supply fuel oil to the main oil tank, compared with an existing fuel oil system, manual oil tank switching is not needed, the operation burden of a pilot can be relieved, and operation errors can be avoided.

    本发明提供一种轻型运动类飞机燃油系统,涉及飞机燃油供给设备技术领域,包括:主油箱、副油箱、第一燃油管、第二燃油管、第三燃油管、第四燃油管、第一电动燃油泵、第二电动燃油泵和燃油阀。第一燃油管的两端分别连接至副油箱和第一电动燃油泵,第二燃油管的两端分别连接至第一电动燃油泵和主油箱,第三燃油管的两端分别连接至主油箱和燃油阀,第四燃油管的一端连接至燃油阀,另一端用于连接发动机,第二电动燃油泵设置在第四燃油管上。在飞机飞行的过程中,当主油箱出现油量告警时,副油箱能够将燃油供给至主油箱,相比于现有的燃油系统,不需要手动切换油箱,可以减轻飞行员的操作负担,能够避免操作失误。
