Sending away Nie Shuai, the bigwigs from the imperial capital, the base returned to its previous working state. Just thinking of the construction of the high-altitude platform, and then looking at the current high-intensity test of the turbofan 10, Yang Hui had to sigh: without such a sharp weapon as the high-altitude platform, the development of the engine is not only slow, but also costs a lot of unjust money.

It also depends on Nie Shuai's actions after returning to the imperial capital this time, if everything goes well and the action is faster, the development of the core engine can benefit from it, and even the future test of the regional power engine will be carried out in the Republic, who let the Germans lose World War II, they can't play with such tall equipment.

Speaking of the Germans, the Germans really arrived, and the German MTU company personnel were in place for a good month, and the accurate Germans really came to the base in a month.

This time it's not too cold, two brand-new Poussin are used to receive the high-level of Germany and West Flight, and the rest of the entourage, sorry, the refurbished bus is not bad, and it will be on it.

As soon as the cooperation between MTU and Pratt & Whitney was straightened out, President Klaus once again led a team to the Republic to negotiate, Germany did not have the ability to independently develop an advanced jet aero engine, and originally thought that the engine of this new aircraft would directly purchase foreign products, but MTU had no hope.

However, the news from the federal government that it is necessary to cooperate in the development of new engines can also win more than 40% of the share of an engine, which has never been done in MTU's foreign cooperation in the development of engines, and MTU is of course happy to do so.

All the actions seemed sincere, and Klaus couldn't wait in the car.

"Director Bai, we are working together to develop this new engine. Don't know what a good solution you have? If not, you can consider our MTU company plan first. ”

MTU also has its own scheme? This is somewhat surprising. In the spirit of the hosts, it is natural to listen to the proposal of the German side first.

Curious to inquire about the Germans' plans. Although the Germans do not have the ability to develop a complete aero engine, the Germans' thinking can be used as a reference, and Germany, which has built a series of doomsday war machines, has divergent thinking about machinery.

"Our German counterparts also have plans, so we have to listen to them, because we still trust the capabilities of our German counterparts."

But with the current strength of MTU, what can it come up with? MTU's plan is also somewhat similar to Yang Hui's plan, which is to use new technology and rely on unique skills to achieve technological leadership. Just like when Rolls-Roy relied on three-rotor technology to establish his hegemony.

The Germans have their own ideas: "Our plan is to develop a pulp fan engine, relying on the low fuel consumption advantage of the pulp fan engine to reduce the operating cost of the engine, which is the market demand for regional airliners." ”

Pulp fan engine

During the oil crisis, this new type of engine, which was more fuel-efficient than turbofan engines, was also the mainstream and promising at that time.

But later, because of the oil crisis, the advantages of the pulp fan engine became less obvious, but its disadvantages and noise were greatly highlighted. So how can this thing be treated?

Now the Germans are still playing the idea of this thing, and Director Bai also doesn't understand what the Germans mean, the noise of civil aircraft has always been strictly controlled, and the Germans won't know this, right?

The so-called puzzled. It should be what Director Bai looks like now, if Yang Hui was here, there would be no such confusion. The last MPC75 project was ready to install this thing, which was also proposed by MTU.

In this life, Yang Hui's butterfly wings did not incite Germany. It is not surprising that MTU, in accordance with the course of history, has once again come up with this plan. However, compared with the gear transmission scheme prepared by Yang Hui. It seems that there is no advantage.

Director Bai didn't have much to say or refute now, so when he returned to the institute, the two sides sat together, and everyone took their time to discuss, and took 10,000 steps back and said that the base originally planned to only develop the core machine, and whether to use turbofans and pulp fans depends on the MTU aspect.

"The fuel consumption of the fan engine is really good, but the noise is quite loud, which is a problem, and the specific situation is discussed slowly by the two parties."

Director Bai said this, obviously not agreeing with MTU's plan, Klaus could also hear it, and besides, the noise was originally a problem with the pulp fan engine, so he didn't say more, so the two bigwigs sat in the car, there was no topic, and it looked quite embarrassing.

The second institute is quite close to the airport, and in recent years, the southwest region has called a small number of cars, and the convoy has raised the speed and rushed forward on the Yunnan-Guizhou Plateau.

It was driven out of the momentum of an off-road vehicle, that is, it was difficult for these two Zanxin Poussin, but fortunately, the new car was indeed quite sturdy, and when he got out of the car, Director Bai patted the gray body, quite satisfied.

"Yes, the German car is really good, and this is the first time that our new car has driven so far."

Hearing the words of agreeing with the German goods, Klaus was naturally happy, although the Volkswagen car in Europe is now quite miserable, but this is also German technology, no matter how backward the technology is put here, it is advanced.

Klaus was a little proud, and a group of people walked towards the conference room, now is the time to test the German aero engine technology, no matter what, such a thing as the performance of German cars crushing the local cars of the Republic will definitely not appear in aviation.

In the second institute, Yang Hui still has a good status, sitting next to Director Bai, ready to talk to the Germans and say that MTU still has some good things.

The host spoke first: "Let me talk about it first, the German counterparts proposed to develop a pulp fan engine, I don't know what everyone thinks." ”

This is naturally in consultation with Xifei and MBB, what kind of engine to use, this is up to the aircraft manufacturer to decide, and now both the base and the MTU are at a loss here.

Pulp fan engine? After Xifei and MBB thought about it carefully, they both shook their heads and rejected this plan, this thing doesn't make much sense to use.

"No, the fan engine is too noisy, and all of our aircraft has made the diameter of the fuselage larger than that of ordinary regional airliners, just to provide a comfortable environment, if the engine noise is too loud, our previous efforts are in vain."

The aircraft developer is very uninterested in the fan engine, which makes MTU very sad, low fuel consumption and low noise are obviously contradictory, you want low noise, you can, hang the engine tail, this is not enough.

Claude Jue's low noise and low fuel consumption are contradictory, but Yang Hui does not think so, and it is not impossible to take into account the two points of low noise and low fuel consumption.

"To control noise and reduce fuel consumption, these two points are strong at the same time, and we have a plan, but I don't know if the German side is willing to help tackle key technologies."

This kind of talk is half, leaving half is the most hated, you just say it directly, now everyone is a cooperative relationship, it must be sincere cooperation.

When Claude heard that there was a way to get the best of both worlds, he became interested, and if he could develop this technology, what kind of pulp fan would he want.

"Of course, as long as this technology is feasible, our MTU company will definitely greatly assist, we are all in a cooperative relationship, and we are counting on making money together in the future."

In the development of the v2500 engine, MTU has thoroughly seen the faces of large companies such as Pratt & Whitney and Rolls-Royce, and these two companies have no intention of playing with MTU at all, but only use MTU's funds to develop their new technologies. Cooperation with the Republic now, at least, is on an equal footing, and it would be best if it could mix up the relationship between Snecma and GM. (To be continued......)
