The Military-industrial Scientific Research System of the Academic Master Chapter 867

Chapter 867, let's call it Turbofan 20!

“80 tons...is it still slightly larger than the Y8?”

Ding Gaoheng did not answer immediately, but thought for a moment, and then asked Chang Haonan.

The latter nodded:

“Yes, the latest improved version of the Y8 is the Y8F400. The maximum take-off weight is about 65 tons, and the load capacity in the ultimate state can reach 20 tons. However, this is only a paper performance, and it will not actually take off like this.”

Chang Haonan has previously participated in the improvement work of Yun8's third-category platform, so he is naturally quite clear about these indicators.

After a short pause, he continued to add:

"If the new medium-sized transport aircraft uses two large bypass ratio turbofan engines as power, it will definitely be larger than the Y-8 and C130 at 80 tons. This is still considering that military transport aircraft require excessive structural redundancy, and it is also There is a demand for short take-off and landing on poor-quality runways, otherwise according to the standards of civil aircraft, a push of about 100 tons is more than enough. "

After all, the core machine of the Turbofan 10 is the foundation of the 4th generation. Even if it is currently in a low-calibration residual state due to process and material problems, the final thrust indicator cannot be weaker than the PS90A, and the fuel consumption and lifespan are not to mention. mentioned.

Two PS90As can propel the 100-ton Tu 214/C909, and the two new engines are obviously no problem.

“I mean, you just said that the market targeted by the new model is users who want to eliminate the old C130 and An12. Will this be inconsistent with their positioning needs?”

Ding Gaoheng expressed his concerns.

In other words, it is the concerns of other people during the project decision-making process.

Because he took out a notebook from the drawer at the same time and wrote down some of the key points that Chang Haonan just said——

Although the People's Liberation Army Aviation itself also has a need to replace medium-sized transport aircraft, it is obviously not urgent as it already has nearly twenty IL-76s of various models on hand and there are still more than a dozen IL-76MF orders to be delivered. .

At least the replacement priority cannot be higher than that of the J-11B and J-10A.

So it is best to achieve quick return on investment through exporting.

In the export of large aircraft, China actually has little decent experience.

Although several export orders for Y8F400 have been signed in recent years, the total transaction volume is only single digits.

In this kind of arms sales to third world countries, the profit on a single product is not much.

Every single or two business is really a huge profit.

Of course, the improved version of Yun 8 is a short-term, fast and low-cost project. If you make money, you will make money.

But new models require research and development funds.

Although using the reputation Chang Haonan has accumulated over the years, and of course the value created, it is not difficult to directly help a project get off the ground.

But it's best to be able to convince people with reason.

In this regard, Chang Haonan certainly has no problem.

So he immediately explained:

"A pure tactical transport aircraft like the C130 has a very single position in the equipment sequence and must be used in conjunction with larger strategic transport aircraft. In the United States, it used to be the C141 and later the C17. The Soviets even directly canceled the An-12 The upgrade plan is to use the Il-76 as a general transport aircraft and pair it with the larger An-22 to perform airlift missions..."

"But this is a method that only big countries, or at least regional powers, can afford. Now that the Cold War is over, most countries have begun to relax their investment in military affairs, and they cannot afford to serve such a complex system, so for small and medium-sized countries , in fact, we need less professional models with more complete functions.”

"Our new transport aircraft can directly refer to the fuselage cross-section of the IL-76, maintaining or slightly reducing the width, mainly reducing the length and wingspan. In this way, although the volume is only 20 tons larger than the C130, it can actually carry cargo The volume is much larger. For small and medium-sized countries, one model covers all needs, and for us, it can also be used as a light transport aircraft in a combination of light, medium and heavy. "

“You can even consider arranging the hardware system required for aerial refueling on the outside of the wing during design. As long as the oil tank is installed in the cabin, it can assume part of the functions of an aerial tanker..."

Chang Haonan's idea is actually to use one machine for multiple purposes.

It is hard for people who were here at the turn of the century, especially after 1996, when the Chinese began to bear external military pressure again, to imagine how exaggerated the level of armaments in countries around the world has become after entering the 21st century.

After all, during the Cold War, the goal of many armies was to “make citizens think they were protected.”

Now that there is no threat from the Warsaw Pact, even without an army, the citizens can think that they are protected.

Therefore, not to mention small countries in the literal sense, even some countries that could be called "great powers" in the past, the military can still take care of themselves.

What are the strategic transportation needs?

It may not be something you can catch up with every few years.

When the time comes, go rent some strategic transport aircraft.

There are quite a few countries with this kind of mentality...

After hearing Chang Haonan's complete plan, Ding Gaoheng did not hesitate for too long and answered:

“No one can say anything about equipment research and development, so whether the project is approved or not depends on the judgment of the aviation industry and the approval of superiors.”

“Of course, from my personal point of view, your idea should be feasible...”

Actually, being able to express your stance to this point is actually an agreement.

As a technical person and a leader, it is naturally impossible to speak too fully.

“Then I'll trouble you, Director Ding…”

Chang Haonan also breathed a sigh of relief. After the design of Turbofan 10 was finalized, the three new models were, after all, the first batch of independent projects after the establishment of the Aerospace Power Group.

Although from the perspective of a reborn person, there will definitely be a huge market in the future.

But it is always safer to find your next home in advance.

Otherwise, it would be embarrassing if his research and development progress is too fast and the engine has been finalized but no suitable installation project has been found.

“By the way, Xiao Chang.”

Ding Gaoheng said as he closed the notebook that had filled most of the page:

“What are you going to call this new model of engine?”

The official equipment model names are actually given by the military. Sometimes manufacturers have another naming system.

For example, J-5 is Dongfeng 101, J-6 is Dongfeng 102...

But later, domestic R&D work was in a state of chaos for a long time, and this set of rules was gradually abandoned.

As it is developed in accordance with the requirements of the military, it is basically just called the model name directly.

In turn, the military sometimes refers to the manufacturer's name.

“Turbofan 20…”

Chang Haonan almost didn't think about it before he put the name on it.

"The turbofan 11 is the power to copy the GJ8, the turbofan 12 is a model that was discontinued in the 1980s, the turbofan 13 is a core machine model proposed by Liyang in 1997, and the number 14 has been used by the turbojet 14 , and it is also considered a new model, so skip over and leave the turbofan 15 for the real fourth-generation engine..."

“Instead of continuing to line up one after another, this large bypass ratio turbofan is a brand new beginning for our country, so it is better to get it right in one step and jump directly to Turbofan 20..."

Although the situation is similar to that of Turbofan 10, whether it is Turbofan 15 or Turbofan 20, they have almost no technical relationship with the previous model of the same name.

But once you get used to this, it's still hard to change.

In this regard, Ding Gaoheng, who has no baggage, naturally follows the good path.

Then, the two continued to chat about other things related to Turbofan 20.

After about half an hour, Chang Haonan was ready to get up and leave.

However, just when he was about to find a chance to say goodbye, he suddenly remembered something.

“Speaking of which, Director Ding, when will the first commercial route operation of C808 be scheduled?”

Chang Haonan asked:

“It seems that I haven't received the invitation from Hufei yet.”

He had made an agreement with Li Yabo before, letting the latter strive for the opportunity to participate in the maiden flight of C808.

But the latter was distracted by him halfway to study carbon fiber laser processing and prepare to publish nature.

This research cycle is relatively long.

So, he, the mentor, still had to make up for the missing piece.

Hearing Chang Haonan's question, Ding Gaoheng was stunned for a moment, and then realized that Chang Haonan, as the leader of the Aviation Power Group, had indeed not received the situation report from Hufei.

“That's right, it was originally planned for November, but now it may be postponed to March or April next year.”

Ding Gaoheng replied.

"ha?"

Chang Haonan was stunned.

To be honest, he hasn't encountered a project delay for a long time...

Especially for C808, even the evidence collection has been completed, so the follow-up process should be smooth.

But soon, Ding Gaoheng's further explanation made Chang Haonan change from surprise to joy:

"Ermao's Ivchenko and Motorsic had some troubles in the delivery of some parts, which caused the engines on the mass-produced machines to not come off the production line. Now the Ufa Engine Industrial Complex and the Moscow Salyut Factory We are looking for ways to fill this gap..."

“That would be great…”

This was originally part of Chang Haonan's plan, so his expression at this time was probably similar to Jim Hacker's when he just heard that the former prime minister died of a heart attack.

After recalling almost all the pain he had experienced in his two lives, he barely suppressed his smile:

“That's a shame.”

"According to the contract, they may have to pay us a large amount of liquidated damages..."
