How to refuel the helicopter? Can you let the tanker connect the pipe to the plane? Ask for answers and offer a reward for high scores.

1. Aircraft on the ground and civil aircraft flying in the sky are refueled by refueling equipment (refueling trucks and refueling platforms) on the ground.

2. In addition to refueling on the ground, combat aircraft flying in the sky can also refuel in the air with tankers. At present, aerial refueling can be divided into hard tube refueling and hose refueling.

There is a special plane to refuel during the flight. There is a special bus at the airport. The oil used in airplanes is very light.

The oil of civil aviation aircraft is stored in the wing, and it is refueled by the tanker when waiting for passengers, which can be seen in the airport terminal.

The plane is a big man who drinks oil. Boeing 747-400, the largest aircraft, refuels 170 tons at a time. Therefore, aircraft refueling has its own characteristics. There are two ways to refuel an airplane, one is to refuel under the wing and the other is to refuel on the wing. Small aircraft are mainly used for refueling on the wing, and large aircraft are all used for refueling under the wing. There are two types of refueling vehicles: tank refueling vehicles and pipeline refueling vehicles.

6. The tanker transports the fuel from the oil storage depot to the fuel tank of the tanker and drives it to the side of the aircraft to refuel. Tank wagons vary from 1200 liters to 85000 liters according to their capacity. After the fuel is transported from the oil depot to the refueling well on the tarmac through the underground pipeline, the hose of the refueling truck of the pipeline refueling vehicle connects the oil well with the aircraft refueling joint.

7. Pipeline refueling shortens the refueling time and reduces the possibility of fuel evaporation and pollution, which is safe and efficient, but it is expensive to build oil pipelines, refueling wells and buy pipeline refueling trucks. Before the aircraft refuels, there are special personnel to test the oil products to ensure that the added fuel is qualified.
