When the two pilots of the first aircraft group stepped off the plane, they also knew about the situation from the ground staff as soon as possible, and no matter what else happened, they put down the Wen Jiàn in their hands and walked quickly to the tail of the plane, they were faster than the group of people led by Yang Hui, but this was not too important.

A group of people surrounded the tail of the plane, looking at the tail of the plane that had a violent friction with the runway just now, and they all had a sudden realization on their expressions, it turned out that this plane was designed with this thing!

Tang Changhong ran to the bottom of the tail again, touched the part that had become unlooked after the friction just now, and after careful inspection, he nodded affirmatively to Chief Master Ma, and then walked out to pat the ash on it, and said indifferently.

"Everyone has also seen that the friction with the runway just now is actually just the friction block we designed in the tail, and a lot of friction and impact are absorbed and released by the friction block, and this tail wiping will not cause any structural damage to the aircraft, not even the paint has a trace of scratching, only need to spend a hundred dollars to replace this iron friction block."

The tail design skid for the aircraft is a design that only small aircraft will have, and now it is designed to large civil airliners, which must have its reasons, and it just so happens that this accident can not be a big problem depends on this design.

"Designing friction blocks for the tail of the aircraft is used to reduce the damage to the aircraft structure when the tail is wiped on the ground, and it is even possible to completely offset the damage. This is the design scheme of the Boeing 737, although there have been many Boeing 737 tail wiping accidents before, but it has never caused damage to the aircraft structure itself, and I have never seen it like the MPC-75 today. ”

Lufthansa is the leader of European civil aviation companies and the fourth largest civil aviation company in the world. In addition, other civil aviation companies that have placed orders to purchase MPC-75 have not encountered accidents such as the tail of the aircraft brushing the runway. Everyone has their own scale in their hearts, and after hearing the affirmation from Lufthansa, they appreciate the design of the MPC-75 even more.

Similarly, some people are wondering what is the difference between the friction blocks of this aircraft? No, someone immediately stood up: "Judging from the actual effect of this design just now, it should be much better than the one used on the Boeing 737." How are you able to do this without any damage to the airplane?"

Such a question simply has no meaning, before Yang Hui can speak, seeing that his design is being questioned, the chief engineer of MBB can't wait to rush out, this kind of thing is absolutely unbearable!

"No, no, you can't question our design, the friction block design used in this aircraft is able to absorb almost all the impact, friction force, because of the complete system design provided by our MBB company. Behind the friction block on this surface is the revolutionary result of MBB's $8 million investment, which has the same design principle as the oil-air shock absorber used on the landing gear.

Seeing that the chief designer of the MBB company has a tendency to turn the scene into an academic report, Yang Hui hurriedly interrupted him: "Therefore, the anti-tail friction system designed by MBB is absolutely reliable, and everyone can trust our technology." ”

This is all said and done, and most people know that this matter is basically reliable, and they will not go to the bottom of it. But the problem is that this time the representative from Saudi Arabian Airlines does not know what is going on. I really didn't know how to ask again.

"I studied aerospace manufacturing at the Massachusetts Institute of Technology (MIT) and returned home to work for Saudi Airlines as a fleet technical supervisor. Responsible for the performance, safety and life assessment of all the company's aircraft. There are some doubts about the oil-air shock absorption system just mentioned, the landing gear of a set of 737 passenger aircraft also made with this technology is about one ton, and you use this technology to the tail anti-friction system, how much does this system get? ”

Ooh! Yang Hui said that why is this guy pretending to be so forced, it turned out to be a high-achieving student from the Department of Aeronautics and Astronautics of Mashen Institute of Technology in the United States, and it seems normal to pretend to be forced and show off his knowledge at this time. After all, it is certainly not an ordinary person to be able to study at MIT, and after learning a belly of technology, he can only work as an airline maintenance manager after returning to Saudi Arabia, which has to be said to be a kind of sadness!

In contrast, even though many aviation students in the Republic may not learn much in school, there is a huge arena for them to perform. In the future work, you can grow rapidly, which is something that a country like Saudi Arabia will never give, even if such a country cultivates talents, it is destined to be buried and finally lost to everyone. Or to marry someone.

At this time, Yang Hui no longer felt unhappy, and some were just a little sad, which was to explain patiently: "Sure enough, it is a top student of MIT, and you can see the shortcomings of our system at a glance, yes, the weight of this system adds up to 240 kilograms, which is the only shortcoming of the whole system." ”

Hearing that the MPC-75 is loaded with such a heavy set of things, a group of purchasers who praised it just now have their own ideas, and such a heavy set of things can be regarded as a set

Even Lufthansa said: "This system is a bit too heavy, but it has already offset the advantages it brings, right?" At a time when Boeing, McDonnell Douglas, and Airbus are all trying to reduce every kilogram of weight that is possible, is your current design a little out of line with the world trend? ”

Yang Hui didn't know what the purpose of saying this was, but he definitely wouldn't agree with this, for the safety of the plane, paying this weight was acceptable in his opinion, and it was also a point that must be accepted.

"We don't agree with this, the reason why we design this way, is because of our design ideas, is to reflect our great attention to civil aviation flight safety, our design team to undertake the design of the safest civil aviation passenger aircraft, to provide the greatest safety for every passenger!"

In this way, the words are unusually firm, which is a point that must be paid attention to for MPC-75 and the nascent aviation manufacturing industry in China and Germany, the nascent MPC-75 can not withstand any safety problems caused by the turmoil, and if you don't pay attention to the boat, it will capsize.

After Yang Hui finished speaking, the engineers of the United Passenger Aircraft Company, the design team of the 603 Institute, and even the German chief engineer of MBB all nodded affirmatively, and they supported Yang Hui's words with actions.

Again, the representative of the Saudi Civil Aviation Company: "The obligation to design the safest civil airliner? It seems that this does not exist in the world! The obligation of a civil airliner manufacturing company should be to produce the most economical passenger aircraft, and only in this way can you get orders and achieve profitability for the company, which you don't have to deny, Boeing, McDonnell Douglas, Airbus and other giants are like this, you don't have to be embarrassed. ”

Yang Hui did not deny this statement, but United Passenger Aircraft Company still has its own insistence: "You also said that it is the purpose of Boeing, Airbus, and McDonnell Douglas to provide the most economical passenger aircraft, and they can give up some safety for the sake of economy, but we can't do this." United Airliner Company has its own philosophy, in our view safety is always the most important, we will always practice the purpose of people-oriented, now and in the future! Of course, our MPC-75 will not be worse than other aircraft in terms of economy, advanced high-efficiency fuel-saving engine, aluminum-lithium alloy materials, and three-stage cockpit layout are all innovative efforts we have made for economy.
