At the Zhuhai Air Show site, transportation -20 and oil-20 are undoubtedly a very special existence.
Their huge appearance, beautiful lines, and exquisite workmanship have won many admirations from the audience.When he appeared on the first day, he chatted with a photographer. He said that when he walked at the end of the inner field, he felt that such a huge aircraft gave him a very strong sense of oppression on his head, and he would feelVery excited -this large -scale transport aircraft designed and manufactured in China did not dare to think about it before.
Oil-20A is a tanker developed on the basis of transportation -20. Many people will use the refueling pod under the wingRecognize.In fact, there are differences in other details of oil-20 and transport-20. This article will explain to you in a comparison way.
There is a refueling pod on each side of the oil-20 wing, and there is a small dual-leaf propeller on the front of the pod.Provide power for pod.In addition, there is also a set of refueling equipment inside the tail, which is also refueling for other aircraft by releasing the hose.In this way, there are three sets of air refueling equipment, but it does not mean that it can refuel the three aircraft at the same time. After all, the distance between the three refueling hoses is very limited.
Yun-20 is the main landing capsule on the right.Note that the upper streaming cover and the fuselage are a arc, and the skin of the upper part of the landing frame has inner concave lines.
The combination part of the upper and fuselage side of the fuselage is a straight line, which looks more concise.At the same time, the upper skin is flat, and the difficulty of processing is lower than the Yun-20.Of course, the cost will be lower.
Yun-20 from left to the landing of the folding cover, the upper curve is very obvious.
The oil-20 left-side rectifier close-up, the lines and skin shape are more concise.
Yun-20 left photos on the left. Note that the lines behind the rectifier on the left are smoothly put inward.
When the tail door is opened, a binding of a binding with a rectifier.
The tail of the ups and downs of the loser sheet of oil-20 is gathered outward, and there is a straight line extending to the rear, which looks more powerfulEssence
Yun-20 vertical tail, the front is very smooth.
The oil transportation-20 vertical tail has a transparent cabin mouth, which seems to be a visiting light.
The left wing of the oil-20 is the navigation light in the front, and the side is a strip-shaped formation light.You can see the discharge brush of the rear edge of the rudder.There is no difference between this part of the design.
The oil transportation-20 is being performed.
The oil transport-20 releases three refueling hoses.
The front landing gear of the Yun-20, when the ground is parked, only the two rear open caps are opened.There are two larger cabins in the front, which are only opened when the landing gear is closed, so as to put away or put down the landing frame forward, so that the wheels can enter and exit the landing frame.The advantage of this design is to reduce the exposure area of the landing frame and reduce the chance of inducing failure.
The front cabin door is opened through the white control lever below.There is a folding ladder inside the cabin.
The "please cut this area" on the side of the fuselage. When you meet the public when you meet the publicOne of the hot topics.In fact, if you go to the Aviation Museum, you have seen the standard-painted rice-8 helicopter, and the side of the fuselage has the same tags and prompts.
Oil-20 is designed with a T-shaped rear wing. There is a visiting light on each side of the horizontal rear wing, which is more convenient for night operations.
The difference between the oil-20 and transport-20 mentioned above, I think it is not specifically designed for oil transportation-20, but because the machine is later produced in the later stageThis is an improved design based on usage.In other words, these are not exclusive designs of oil transportation-20, but will be applied to a new batch of transport-20 in the future.The changes in these design details can only have a better understanding of the scene.
