PURPOSE: An unloading arm for refueling and an operational method thereof are provided to be easily coupled to a tank truck by controlling the length and angle of the unloading arm according to a gap between an aircraft fuel storage tank and the tank truck. CONSTITUTION: An unloading arm for refueling comprises a fluid flow part(110), a joint part(130), and a pipe(150). The fluid flow part is connected to a tank truck to form a moving path of aircraft fuel. One side of the fluid flow part is reciprocated by a piston motion so that the length of the fluid flow part to the tank truck can be controlled. The joint part is coupled to one side of the fluid flow part to rotate the fluid flow part on a xy-plane and an xz-plane. The pipe connects the fluid flow part and the joint part to the aircraft fuel storage tank. |
