The invention belongs to the field of an airplane overall design, and particularly relates to a ground oil supply device and method for keeping a take-off gravity center of an airplane. The device comprises an airplane oil tank, an airplane oil tank vent pipe, an on-board electromagnet, a ground oil supply connector and a ground oil tank. One end of the airplane oil tank vent pipe is connected with the airplane oil tank, and the other end is provided with the on-board electromagnet; one end of the ground oil supply pipe is connected with the ground oil tank, and the other end is provided witha ground oil supply connector; and the ground oil supply connector makes contact with the on-board electromagnet, when the on-board electromagnet is powered on, a magnetic force is generated to attract the ground oil supply connector, the ground oil supply pipe is connected with the airplane oil tank vent pipe, and when the on-board electromagnet is powered off, the magnetic force disappears, theground oil supply connector is disconnected, and the ground oil supply pipe is separated from the airplane oil tank vent pipe. Oil is effectively supplied to the airplane through the ground oil tank in a ground preparation stage, a gravity center change of the airplane is reduced, a distance between a rocket thrust line of a rocket-boosted airplane and the gravity center of the airplane is guaranteed, and the airplane flight safety is improved.

    本申请属于飞机总体设计领域,特别涉及一种保持飞机起飞重心的地面供油装置及方法,装置包括:飞机油箱、飞机油箱通气管、机上电磁铁、地面供油接头以及地面油箱。飞机油箱通气管的一端与飞机油箱连接,另一端设置有机上电磁铁;地面供油管的一端与地面油箱连接,另一端设置有地面供油接头;地面供油接头与机上电磁铁接触,当机上电磁铁接通供电时产生磁力,将地面供油接头吸住,地面供油管与飞机油箱通气管连通,当机上电磁铁断开供电时磁力消失,与地面供油接头脱开,地面供油管与飞机油箱通气管分离。本申请飞机在地面准备阶段通过地面油箱有效供油,减少飞机重心变化,保证了火箭助推飞机火箭推力线与飞机重心之间的距离,提高飞机飞行安全。
