The invention belongs to the field of fuel tank fuel control, and relates to an aircraft left and right fuel tank fuel balance system and method.The aircraft left and right fuel tank fuel balance system comprises a left fuel unit, a right fuel unit and a control processor, and an isolation valve is arranged between the left fuel unit and the right fuel unit; all electric elements in the left fuel unit and the right fuel unit are controlled through the control processor; the flight control system commands the processor to use different strategies under different conditions, the rapid strategy is used for dealing with the situation that the fuel quantity of the left side and the right side of an airplane has large deviation under the emergency condition, and the fuel on the left side and the right side can be balanced in a short time; the normal strategy of fuel can balance the fuel quantity of the corresponding fuel tanks on the left side and the right side of the aircraft more accurately, so that the gravity center of the aircraft is kept near the symmetry plane, and the flight safety of the aircraft is guaranteed to the maximum extent.

    本申请属于油箱燃油控制领域,为一种飞机左右油箱燃油平衡系统及方法,包括左侧燃油单元、右侧燃油单元和控制处理器,左侧燃油单元与右侧燃油单元之间设置有隔离阀;通过控制处理器对左侧燃油单元、右侧燃油单元内部的所有用电元件进行控制;通过飞控系统命令控制处理器在不同情况下使用不同的策略,使用快速策略用以应对紧急情况下飞机左右两侧燃油油量存在较大偏差的状况,可在较短时间内平衡左右两侧燃油;燃油的正常策略可更加精准地平衡飞机左右两侧相对应的油箱燃油量,使得飞机的重心保持在对称面附近,极大限度上保证飞机的飞行安全。
