Background

The amphibious aircraft can take off and land on water surfaces such as land runways, rivers, lakes, reservoirs, sea surfaces and the like, and has very remarkable effect in water/sea rescue activities. At present, the refueling of the amphibious overwater aircraft can be completed on land or on the water surface.

The refueling of the amphibious aircraft on the water surface is mainly carried out in a longitudinal refueling mode, namely, a refueling ship/engine is arranged in front, an oil receiving machine is arranged behind the amphibious aircraft, a pressure refueling hose with a buoy is thrown down at the tail of the refueling ship/engine by the refueling ship/engine, the buoy is fished up by the oil receiving machine, the pressure refueling hose is connected, and then refueling is carried out. The mode that the refueling is carried out before and after the water surface through the refueling ship/machine and the oil receiving machine has defects, such as: the refueling ship/machine and the oil receiving machine all sail on the water surface at low speed, relative movement and position change can not be avoided between the refueling ship/machine and the oil receiving machine due to the action of wind power and surge on the water surface, and the problem of difficult connection and disconnection can occur when a refueling operator butt joints and releases a pressure refueling nozzle at the end of a pressure refueling hose and a pressure refueling joint on the oil receiving machine; for another example, the pressure refueling hose may cause stress changes between the pressure refueling nozzle and the pressure refueling joint, and between the refueling ship/engine and the oil tank structure of the oil receiver when surging, which may cause the situations of joint disconnection, oil leakage of pipeline, oil tank damage, etc., and may cause serious consequences such as refueling failure, environmental pollution, airplane damage, even fire, etc.; in addition, some amphibious aircraft pressure adding joints are arranged on the lower wing surface of the wing in the upper single-wing layout, the distance between the pressure adding joints and the water surface is higher, the actual aircraft type is more than 3 meters, the oiler can not complete the butt joint of the pressure oiling joint nozzle and the pressure oiling joint on an oil receiving machine and can complete the butt joint only by means of a small boat and a special bracket attached to an oiler/plane, and the oiling difficulty and the safety risk are greatly increased.
