In a few days of meetings, Yang Hui really became an observer, because the old man Ma had participated in the development of Yun Shi, although he did not finish the journey, but the general process was known.

Originally, MBB thought that it could suppress Xifei with its own experience, but Mr. Ma's unique insights can always give key opinions at critical moments, so that the Germans always feel that the strength of Xifei is not to the end.

It wasn't until the third day that the two sides finally had a preliminary positioning and general design layout for the new aircraft, and Yang Hui listened to it for so long all the way, witnessing the formation of the preliminary plan step by step, and the MPC75 project in Yang Hui's memory of the future generations constantly overlapped.

However, the third day of the meeting was stopped, according to the plan, this day is a big day for the westward flight, the new four-engine oil six platform will be officially tested, the previous ground running test has already been completed, everyone is waiting for this day.

August is the hottest time, especially in the northwest region, although it is only nine o'clock in the morning, but Yang Hui also feels the hot and hot enthusiasm of the northwest region.

Yang Hui and the German side were both guests to observe the test flight, and were allowed to watch the test flight from a distance in the audience, enduring the heat, and everyone stared intently at the hangar in the distance.

Finally, a plane was slowly dragged out of the hangar and immediately dragged onto the runway for pre-takeoff preparations, and Yang Hui could clearly see that the Germans were dumbfounded.

Obviously, it was just a copy of the Soviet TU16 aircraft, but now it seems to be too different from what Flory thought, and the two engines hanging under the wings all indicate that this aircraft is no longer the original twin-engine medium bomber.

"Oh, four engines, now this plane has four engines. Is this my dazzling eye? It's incredible that the old Figure 16 can be improved in this way. ”

Florey was not the only one who came to negotiate, but also the designers of MBB, who was in charge of technology, mainly focused on large aircraft after the war, and this time he came to discuss the large passenger aircraft project, and naturally he also came to negotiate a designer with experience in large aircraft.

The Germans have a head full of cogs. Although he was rigid, he was not blind, and the designer who came with him picked up the telescope on the table and carefully looked at the big guy lying on the runway, and he could still see a lot of things from the appearance alone.

"The hiss was unexpected, God, I really didn't expect it."

Reluctantly put down the telescope in his hand, and now is the time for him, a technical designer, to make an evaluation, which will be the reference data of MBB's senior management. In order to re-evaluate the strength of Xifei, it will directly affect the status of Xifei in the cooperation of new aircraft.

"First of all, it is certain that this aircraft is indeed an improvement on the basis of Figure 16, and it bears the imprint of Figure 16, both in terms of the aerodynamic layout of the fuselage and in terms of the position of the two engines on the inside."

First of all, the original identity of the plane was confirmed, and then a rough three-view was drawn in a portable notebook, and if you want to express the general situation of the plane clearly, you still need to draw it.

Next to the drawing is a series of formulas. It can be evaluated by the data that is derived at the end, so that it can be more convincing. Although these data are not very accurate, it is probably enough to watch the excitement and analyze.

"The aircraft is powered by four engines, but it should no longer be the original engine of the Figure 16, which is analyzed from the wing structure. The wing of this aircraft has not been changed much, so it will certainly not be able to withstand the thrust of a nine-ton thrust engine, which looks like it should be a Spey 512. ”

Yang Hui on the side listened to the Germans' analysis. I very much agree, I can see the structure from the appearance, and then analyze the engine thrust from the structure, which is awesome. The most important thing is that I really let this one analyze it right, Spey 202 (turbofan nine) no afterburner version is almost Spey 512.

I heard the results of the analysis from the designers under my command. Flory is completely convinced, and being able to change the Figure 16 to this is also a highlight, and the entire powertrain can be regarded as a complete redesign.

Flory once again refreshed his assessment of the West Flying Company, such a company's strength is really good, if the real test flight is successful, perhaps the later passenger aircraft project can listen to the opinions of the West Aviation Company.

Touching his big nose, he couldn't wait to pick up the telescope on the table to verify that it was really as he said.

And when Flory saw the new H-6 from the telescope, he was finally convinced, this was really a new four-engine plane, and even Flory saw that the engine had been started, and the fan blades at the air intake were spinning rapidly.

Sitting down, Flory remembered Yang Hui next to him, as if he hadn't shown a little surprise from the beginning, it seemed that this person should have known the news for a long time, maybe he could find out something.

At this time, he finally became affectionate, and his old-fashioned and serious facial expression squeezed out a little smile, Yang Hui felt uncomfortable all over his body, it should be that this smile was too subversive of the tradition of the Germans.

"Yang, it seems that you knew about this plane in advance, can you answer this plane for us? We are very curious about this aircraft, and through this aircraft we need to reassess the strength of the West Flying Company. ”

Of course, Yang Hui knows the news of this new plane, and now Yang Hui can reveal some less important news, and the evaluation of others will sound more convincing than Xifei's own introduction.

"Yes, this new aircraft is an improved version of the Tu-16 (H-6), but now it is very different from the old Tu-16, with four engines, so that the take-off weight of this aircraft has reached nearly 100 tons."

The take-off weight of 100 tons is a hurdle, and if you can develop an aircraft of more than 100 tons, you can proudly say that you can develop a large aircraft, which is a symbol of strength.

"In fact, this big change was only started last year, and it has only been just a year now."

This time, Yang Hui is blowing up the bull for Xifei, and in just one year of the project, he has completed the complex power system, and at the same time, the body has been redesigned, and the oil pipeline has to be arranged. In just one year, Yang Hui himself felt that it was a little too fast, but fortunately, Xifei had the information on the bombardment six.

It took only a year from the design to the manufacture of the prototype to the first test flight, and the Germans were not calm at all. Flory immediately jumped up from the stool, what Yang Hui said just now was too fast, unbelievably fast.

Wide-eyed and frightened, this is completely unscientific: "No, such a big change can make a prototype for its first flight in a year, you are talking nonsense, this is absolutely impossible." ”

Flory's exaggerated expression made Yang Hui stunned, what he said was the truth, the project was approved last year and in fact, it has indeed only been a year.

Shaking his head, since Florey doesn't believe it, then Yang Hui has no choice, no one believes the truth these days, let's honestly watch the test flight.

"Whether you believe it or not, this is the case, this aircraft is the fuel platform for our air tanker, and the air tanker project was established last August. You can ask the Britons next to them, they are the provider of air refueling equipment accessories, and they all know when the tanker project started, this is not a secret project. ”

Yang Hui unreservedly confessed to Flory that the Germans would go if they wanted to ask the British, and this was the case. It's just that Yang Hui chose not to say about the H-6I that was dismounted before, and he would not say that the new aircraft this time uses the technology of H-6I. (To be continued......)
