Chapter 262 The next step is to develop a turbofan engine
Xie Kangquan returned to his own office full of disappointment.
Originally, I hoped to use some channels and resources to import a batch of spare parts, but my hope fell through. After returning to my desk, I kept sighing.
what should we do?
He took out another cigarette and lit it, and took a deep breath. After thinking about it, he still felt that he should communicate with Lin Feng, so he picked up the phone and called.
"Boss Lin, you already know the matter."
Even though he didn't say anything specifically, Lin Feng understood it all at once, and replied, "Well, we already know."
Xie Kangquan said worriedly, "In this way, our helicopter production will inevitably be affected. Have you thought about countermeasures? Have you assessed how much impact it will have?"
Lin Feng smiled easily, "Director Xie, there is no need to worry too much."
what!
This is the end of the matter, you tell me there is no need to worry too much.
Is this comforting me?
Xie Kangquan said eagerly, "I'm not worried that we can't do it. Whether it's a heavy-duty armed helicopter or a 'Tianlong' transport helicopter, we have placed great hopes on it, and we can't be seriously affected by the problem of imported parts. "
Lin Feng said, "There is really no need to worry too much. We checked the inventory, and the imported parts of 'Tianlong' reached 25 units, and the heavy armed helicopters also exceeded 10 units. Not only that the production of these 6 prototypes is enough, In the future, small batch production will be enough for several units."
Xie Kangquan was still a little worried and said, "Although there are these stocks, the stocks are exhausted. As far as I know, the 'Tianlong' transport helicopter will be mass-produced soon. Even if there are 25 units in stock, it won't last long."
Lin Feng said, "It's true that it won't last for a few months, but we purchased another batch of imported parts after the Paris Air Show, including 30 imported parts of 'Tianlong' and 20 imported parts of heavy armed helicopters."
"We also checked the situation of these imported parts. They have already passed customs and are currently on the freighter returning to China. It's just that this batch of imported parts is carried by a foreign freighter, which belongs to a foreign ocean transportation company."
Lin Feng briefly explained the situation.
The first batch of imported parts was purchased by the military using some channels and resources, and the purchase of the second batch of imported parts was handed over to Leihuo Technology Industry Group, including the third batch of purchases launched after the Paris Air Show. The group is responsible for itself.
Leihuo Technology Industrial Group has begun to take shape, has its own purchasing department, and the strength of the department is not bad, so there is no need to go through the military, and directly contact overseas manufacturers and place orders for purchases.
Hearing that another batch of imported parts was already on the freighter returning home, Xie Kangquan felt relieved, "Great, this can solve our urgent need."
Lin Feng said, "It's impossible for some people in the beautiful country to try to jam our necks. I've already thought about it. Whether it's our 'Tianlong' transport helicopter or our heavy-duty armed helicopter, they will all be activated 100% localization."
Xie Kangquan said with a little surprise, "Mr. Lin, it is really 100% localized. Can we manufacture these imported parts in our own country?"
Lin Feng replied affirmatively, "Of course we can make them ourselves, and they will be made in a short time."
Of course, this is certain, because Lin Feng has the detailed manufacturing process of all parts in his brain, and he can manufacture it by himself.
In the beginning, why didn't we manufacture it ourselves? The main reason was to get the helicopter out as soon as possible, save time by directly purchasing imported parts, and not need to wait for these spare parts for the manufacture of helicopters.
There is a complete set of detailed craftsmanship. Although I can manufacture it myself, it takes time, so I can import it directly. Now that it is banned from sale, I can only manufacture it myself.
After making this phone call, Xie Kangquan was in a good mood.
Never expected that Lin Feng gave him such a big surprise!
Not only has a batch of imported parts been purchased long ago, but also the production and manufacture can be done by ourselves, so the problem is easily solved.
Xie Kangquan, who was relaxed all over, took out another cigarette and lit it, took a few puffs happily, and then got up to go out. He wanted to report these to the superiors to make the leaders happy.
As for Lin Feng, after answering the call from Xie Kangquan, he was thinking about the production of these spare parts.
There are two main ways.First, Leihuo Technology Industry Group provides the manufacturing process, and some domestic manufacturers undertake the manufacturing.Second, it is completely manufactured by Leihuo Technology Industry Group itself.
After thinking about it, Lin Feng still decided to adopt the first method, mainly because there are related manufacturing companies in the country, and the equipment and technicians are ready-made, so there is no need to buy equipment by himself, and then build a factory for production.
After choosing this method, Lin Feng "looked through" the process information of these spare parts in his mind. It is still an old rule to figure out the manufacturing process of the part with the most difficulty in production and the highest technical content.
So, for the next few days, whenever Lin Feng had time, he would sit in front of his computer and use CAD to compile the process rules himself.
Pertone Corporation.
Vice President Sean was listening to Pete's report again, "Boss, our domestic companies have already imposed a complete ban on Leihuo Industrial Group, but"
Sean frowned slightly, and asked, "Just what, just say it directly, don't beat around the bush."
Pete said, "It's just that before we took the measures to ban sales, a batch of imported parts purchased by Leihuo Technology Industry Group has already cleared customs, and it is estimated that they are almost arriving at the local port of Huaxia at this time."
what!
There is still such a situation.
Sean said a little angrily, "How many copies are there in total, have you checked it out?"
Pete replied, "There are 30 units in total, which is enough for Leihuo Technology Industrial Group to manufacture 30 'Tianlong' transport aircraft."
Sean's face changed, and he was on the verge of an explosion, and this happened unexpectedly.
Seeing that his boss's expression was not right, Pete quickly comforted him, "Boss, you don't need to worry too much. Even with this batch of spare parts, Leihuo Technology Industry Group will only support it for a few more months, and it will eventually fall into the trap because there are no imported parts. A situation where production is discontinued due to accessories.”
It seems that this is the reason, Xiao En's face softened a lot, and he ordered, "You must continue to pay close attention, and you must block the Leihuo Technology Industrial Group. You must not let any part fall into their hands, and let their helicopters be completely damaged. Unable to manufacture."
"Okay," Pete replied.
Even in their dreams, they would never have imagined that Leihuo Technology Industry Group has a complete set of manufacturing processes, which can be produced in China.
It is estimated that after a year or so, when they see the "Tianlong" transport aircraft of Leihuo Technology Industry Group being produced continuously, they will find that something is wrong. It had no effect.
What people should produce is still being produced, and the monthly output should not be low, and one after another "Tianlong" transport opportunities will be produced.
Leihuo Technology Industrial Group was indeed not affected by the embargo. The production and manufacturing workshops were in full swing, and large-scale production of parts and components began.
In addition to the parts of the helicopter, the first batch of 200 air-to-surface anti-tank missiles has reached the delivery status.
Zhong Zimin is the general user representative of the user stationed in Fenghuang City, and he leads several people to conduct acceptance inspection.
That is to take a look at various quality records, to see if the certificates are complete, to see if there is any abnormality in the appearance of the missile, and so on.
"Mr. Zhong, everything is normal and there is no problem found."
"The quality records are complete, and the certificates are complete, and there are many."
"."
After hearing the report for his subordinates, Zhong Zimin was relieved for a while, nodded and said, "Then sign it, and then we will go to the production site to have a look. The LH1500 turboshaft engine has now entered the stage of mass production."
The front was considered a small batch production, and a total of 62 to 1500 units were produced. As the military ordered dozens of 'Tianlong', it won two foreign trade orders, and a total of [-] 'Tianlong'. A large number of LH[-] type engines are required.
Each 'Dragon' requires two LH1500 turboshaft engines, and then a spare engine.Generally, every 10 "Tianlong" needs about two or three spare engines, mainly for the convenience of field replacement and so on.
After signing, Zhong Zimin and others went to the production site to look around with great interest, that is, Leihuo Helicopter Company is in the provincial capital, otherwise he would like to go there to see the production of helicopters.
The first batch of 200 air-to-ground anti-tank missiles leaves the factory. Most of them will be equipped on the new domestic armed helicopter. This is a medium and light armed helicopter with a maximum take-off weight of less than 5 tons, but it can mount 8 missiles. This missile.
This is the most advanced air-to-ground anti-tank missile in the world. After being equipped with this missile, the combat effectiveness of this domestic armed helicopter will be improved a bit.
Qian Tao and the others are designing and developing a medium-sized special-purpose armed helicopter. The maximum take-off weight is designed to be close to nine tons, and the maximum take-off weight is twice that of the current domestically-made armed helicopter.
This kind of air-to-ground anti-tank missile can also be mounted on this medium-sized armed helicopter. In addition, some surface ships and missile launch vehicles can also launch this kind of missile. The missile has good versatility.
in the office.
Lin Feng stretched and knit for two to three hours without even having time to drink a sip of water. He really felt a little sore and backache.
But the gains are also huge.
Over the past few days, Lin Feng has completed the preparation of more than a dozen key parts and components manufacturing processes, and there are dozens more. get it out.
After saving the prepared process regulations, Lin Feng got up and made a cup of hot tea by himself, thinking in his heart while drinking the tea.
Whether it is a "Tianlong" transport helicopter or a heavy-duty armed helicopter, you don't have to worry about being stuck in the future. In the future, it will be [-]% localized. All parts are either manufactured by Leihuo Technology Industry Group itself, or some related domestic companies are responsible for manufacturing.
These two helicopters represent the ceiling of the industry, "Tianlong" is the ceiling of transport helicopters, and this heavy-duty armed helicopter is also the ceiling of the world's armed helicopters.
In the field of helicopters, there is no need to design and develop for the time being, and the most is to carry out the extended design of the model. For example, the "Tianlong" transport helicopter will have various models such as medical rescue type, air rescue type, special operations type, and maritime patrol type in the future.
Even if it is an extended design, the workload is not too great, and the technical difficulty is not too great. Besides helicopters, what else will Leihuo Technology and Industry Group have in the future.
Lin Feng thought about this question again.
In fact, this question has been thought about many times. With the military orders and foreign trade orders, the financial strength of Leihuo Technology Industrial Group is already very strong, and it is completely possible to consider entering other fields.
Such as another aero-engine.
Like a turbofan engine.
What is the hottest aero engine with the largest production volume now? It is not a turboshaft engine, nor a turbojet engine, nor a turboprop engine, but a turbofan engine.
According to different bypass ratios, turbofan engines are divided into high bypass ratio turbofan engines, medium and small bypass ratio turbofan engines.
Large bypass ratio turbofan engines are mainly used in civil aviation airliners. Its fan diameter is large and its fuel utilization rate is high. The disadvantage is that it has a large windward area and generally only flies at subsonic speeds.
Medium and small bypass ratio engines have a relatively small fan diameter and small windward area, and can fly at supersonic speeds. They are mainly used in military applications, such as fighter jets and bombers, all of which use medium and small bypass ratio turbofan engines.
Holding hot tea, Lin Feng stood in front of the huge floor-to-ceiling windows, condescendingly looking into the distance, thinking about what kind of turbofan engine he should make in his mind.
After thinking about it, I gave up the plan to develop a turbofan engine with a large bypass ratio. Even if you develop this kind of engine, there is no market in China, because it is mainly used in civil aviation airliners. There are only two major customers in the world. It's Airbus and Boeing.
Will people use your engine? This is a big question mark.
Since the market is worrisome, it is better to develop turbofan engines with medium and small bypass ratios. At least there is a domestic market, and the military needs them. In addition, if you want to build fighter jets, bombers, etc. in the future, you will have ready-made engines.
Why do you want a medium and small bypass ratio turbofan engine?
Lin Feng thought of the F22 engine, the F119-PW-100 turbofan engine manufactured by Pratt & Whitney, and the Russian-made AL-31FN engine.
These are the most advanced turbofan engines in the world at present, but because the current information is not developed, Lin Feng is not very familiar with the specific parameters and performance of these two engines, and what can be found in the information is limited.
Know thyself, ever-victorious.
Since he wants to develop turbofan engines with medium and small bypass ratios, he needs to know the advanced military turbofan engines in the world. Lin Feng thought of Xie Kangquan.
The information he has on these turbofan engines is limited, but the military should have more things, so Lin Feng put down his teacup and called Xie Kangquan.
"Thank you, Director, hello."
"Mr. Lin, we have already selected domestic manufacturers, and they will send someone over to contact you."
After the phone call, Xie Kangquan first talked about choosing a manufacturer.Imported parts needed for helicopters began to be localized, which required related manufacturers, and the military helped select some manufacturers.
After hearing Xie Kangquan's words, Lin Feng said, "Director Xie, we will do a good job in communication and contact, but I am calling today because I have other business."
"Oh, tell me, what's the matter." Xie Kangquan was slightly surprised.
Lin Feng said directly, "I need information on Pratt & Whitney's F119-PW-100 turbofan engine, as well as information on the Russian-made AL-31FN engine. The more detailed the better."
Xie Kang said puzzledly, "Boss Lin, you are engaged in turboshaft engines and helicopters, why do you want these materials all of a sudden?"
Is it
He suddenly thought of a possibility, and gradually became a little eager in his heart.
Lin Feng said, "We have reached the ceiling in the field of turboshaft engines and helicopters. I think our focus in the next stage will be the design and development of turbofan engines. All the introduction materials of these engines are required, and the more detailed the better."
Hearing this, Xie Kangquan really became a little excited.
If someone else said something like this, he would definitely dismiss it, I believe you ghost, do you know the technical difficulty of developing a turbofan engine?Looking at the whole world, there are only a few countries that can independently develop turbofan engines.
But these words were spoken by Lin Feng, and he firmly believed them.
Immediately, I couldn't hold back in my heart, and asked quickly, "Mr. Lin, what kind of turbofan engine do you plan to develop, can you disclose it in advance?"
Lin Fengdao, "It must be benchmarked against the world's most advanced turbofan engine, and its performance is basically the same as Pratt & Whitney's F119-PW-100 turbofan engine and the Russian-made AL-31FN engine."
That's a bit of an understatement.
In fact, Lin Feng's plan is to build the world's top engine if he wants to. He must surpass these two engines and become the world's medium and small bypass ratio turbofan engine.
Even if he said it conservatively, Xie Kang felt a sense of happiness descending instantly. The whole country is looking forward to a world-class turbofan engine, but due to the limitation of the aviation industry, this can only become a luxury.
Well now, hope has risen. After Leihuo Technology Industry Group has a plan in this regard, it is estimated that within a few years, world-class turbofan engines with medium and small bypass ratios will come out.
After chatting on the phone, Lin Feng put down the phone and thought in his heart, after carefully reading the materials of these two engines, I will personally draw up the design technical outline, and then let the system design and develop it for me.
While thinking about these things, there was a knock on the door of the office. He Hua opened the door and came in, speaking loudly.
"Boss, the name call for our heavy gunship has come to an end. We have selected a total of ten names. Take a look."
.........
Visiting relatives today, I went to Wuhan and wrote it on my mobile phone in the hotel, but I still tried my best to update [-] characters. Can you guys come with a few monthly tickets to support it?

While thinking about these things, there was a knock on the door of the office. He Hua opened the door and came in, speaking loudly.
"Boss, the name call for our heavy gunship has come to an end. We have selected a total of ten names. Take a look."
