Chapter 867 is called Turbofan 20!
"80 tons...is it still slightly larger than the Yun 8?"
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 just a performance on paper, it won’t take off like this.”
Chang Haonan has previously participated in the improvement of the Y8 III 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 better than the Y-8 and Y-8 in any case. The C130 is bigger than the previous one, 80 tons. This takes into account that military transport aircraft require excessive structural redundancy, and also need to perform short takeoffs and landings on inferior runways. Otherwise, if calculated according to the standards of civil aircraft, it would be 100 tons. The left and right are more than enough.”
After all, the core engine of the Turbofan 10 is based on the fourth generation. Even if it is currently in a low-calibration residual state due to process and material problems, the final thrust indicator is impossible. Weaker than PS90A, not to mention fuel consumption and lifespan.
Both PS90A 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 Worry.
In other words, it is the concerns of others 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, However, with nearly twenty Il-76s of various models on hand and more than a dozen Il-76MF orders yet to be delivered, it is obviously not urgent.
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 export.
China actually has little decent experience in the export of large aircraft.
Although several export orders for Y8F400 have been signed in recent years, the total transaction volume is only single digits.
With this kind of arms sales to third world countries, the profit on a single product is not much.
Every business of one or two planes is really a profit.
Of course, the improved Y8 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 it is not difficult to directly help a project get off the ground by taking advantage of the reputation Chang Haonan has accumulated over the years and of course the value created.
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. Like the United States, It used to be C141, and later it was C17. The Soviets even directly canceled the An-12 upgrade plan and used the IL-76 as a general transport aircraft, paired 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 complicated system. Therefore, for small and medium-sized countries, In fact, we need a model that is less professional but has more complete functions.”
“Our new transport aircraft can directly refer to the fuselage cross-section of the IL-76, maintain or slightly reduce the width, and mainly reduce the length and length. Wingspan. Although the volume is only 20 tons larger than the C130, the actual volume of cargo that can be loaded is much larger. For small and medium-sized countries, one model covers all needs, and for us, it can also 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 the aerial tanker..."
Chang Hao Nan's idea is actually to use one machine for multiple purposes.
It is hard for people 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 strategic transportation needs?
It may not be possible to catch up with something every few years.
When that time comes, let’s rent some strategic transport aircraft.
There are quite a few countries with this mentality...
After listening to 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 to establish a project or not depends on the decision. It needs to be judged by the aviation industry and approved by superiors."
"Of course, from my personal point of view, your idea should be feasible..."
Actually. , being able to express your stance to this point actually means agreeing.
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 the 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, closing the notebook that had filled more than half the page:
“This new model of engine, you guys are ready. What's it called? "
The official equipment model name is actually given by the military. Sometimes the manufacturer has another naming system.
For example, the J-5 is Dongfeng 101, and the J-6 is Dongfeng 102...
But later, domestic research and development work was in a state of chaos for a long time, and this set of rules was gradually abandoned.
For this model, which was developed in accordance with the requirements of the military, it is basically just called the model name.
In turn, the military sometimes refers to the manufacturer's name.
"Turbofan 20..."
Chang Haonan put the name on it almost without thinking.
"The turbofan 11 is the power of the imitation of the Jiejiao 8. 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. The number 14 is The turbojet 14 has already been used, and it is also considered a new model. Skip over it and leave the turbofan 15 to the real fourth-generation engine..."
"Instead of continuing to line up one after another, this big connotation The Dowby 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, Turbofan 15 is also good. , the Turbofan 20, has almost no technical relationship with the previous model of the same name.
But it is still difficult to change if you are used to this thing.
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 C808's first commercial route operation be specifically scheduled?"
Chang Haonan asked:
“I don’t seem to have received an invitation from Hufei.”
He had made an agreement with Li Yabo before, letting the latter strive to participate in the C808 maiden flight. opportunity.
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.
Therefore, 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. The original plan was November, but now it may be postponed to March or April next year."
Ding Gaoheng replied.
“Huh?”
Chang Haonan was stunned.
To be honest, he has not encountered a project delay for a long time...
Especially since C808 has even completed the certification process, 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, in some parts There were some troubles with the delivery, resulting in the engine on the mass-produced machine being unable to come off the production line. Now the Ufa Engine Industrial Complex and the Moscow Salyut Factory are trying to fill this gap..."
"That's 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 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..."
