Chapter 732 Aircraft Modification Qualifications
"This is a good business," Zhang Qihang continued: "Second Uncle, you have an aircraft overhaul factory in the Beijing Military Region. With the technical content of this project, if you can buy their modification plan from the Antonov Design Bureau, You can do it yourself, and you can even make some money with this project..."

Before Zhang Qihang finished speaking, Xia Pingyue shook his head again and again: "Don't think about this kind of thing, the army is not allowed to do business." (Otherwise you will be 404)
"Understandable," Zhang Qihang nodded, and continued, "Since this method doesn't work, the second method is...Second Uncle, can our military region help our company get an aircraft modification qualification? In return, Our company can provide you with a full set of modification and reengine services for 5 aircrafts free of charge."

Ok?
Xia Pingyue, who understood what Zhang Qihang meant, squinted his eyes and began to calculate...

He roughly understood Zhang Qihang's plan: as long as Huateng Industrial Group can obtain the qualification for this aircraft modification, then the rest will be easy to handle. First, they can go to Ukraine and find Antonov Design Bureau to buy their aircraft. A full set of plans for the An-3 aircraft; secondly...

"No." Xia Pingyue frowned and said, "As far as I know, our country doesn't have such a 1000-horsepower turboprop engine either?"

In Xia Pingyue's impression, there are three types of turboprop engines currently in production and under development in China, namely Turboprop-5, Turboprop-6 and Turboprop-9.

其中涡桨-5是一款2000至3000轴马力的涡轮螺旋桨发动机，而涡桨-6是一款3300马力至4000轴马力的涡轮螺旋桨发动机，而涡桨-9则是在直-9直升机上面的那台涡轴-8的基础上以“轴改桨”的方式改进而来的500至800轴马力，这款发动机虽然已经在去年才刚刚获得民航部门颁发的适航许可证，但实际上还有大量的工作要做，远远还达不到正式装机的条件。

Then here comes the problem, what the Yun-5 transport aircraft needs is only a 900 to 1000 engine, and the power of these three turboprop engines is either insufficient or far beyond, and there are only three types of turboprop engines in China. What is Zhang Qihang going to do?
"It is true that there is no turboprop engine of this power level," Zhang Qihang nodded: "But the problem with the engine is actually very easy to deal with, and it can always be solved. The only troublesome thing is the modification qualification of this aircraft."

Although it is just an old-fashioned Yun-5, and it is not a production qualification, but a modification qualification, after all, this is "fishing out of bounds". Go to the territory of the aviation industry department to make a living. If there is no strong support from the army, Don't even think about this kind of thing.

"Is the engine easy to solve?"

Xia Pingyue's frown became more and more severe. He always felt that Zhang Qihang was bragging: If the engine is so easy to solve, maybe our country has already started to replace the Yun-5 with a turboprop engine. How could it be delayed until now? Still not resolved?
"Yes," Zhang Qihang nodded, and explained to Xia Pingyue: "Second uncle, although there is no suitable 1000-horsepower turboprop engine in our country, there are turboprop engines in this power output range in the world. Many, such as the TPE311 series of Honeywell in the United States, the PT6A series of Pratt & Whitney Canada, the Ivchenko Design Bureau of Ukraine, the Kuznetsov Design Bureau of Russia, and the Klimov Design Bureau. All bureaus have suitable turboprop engines.

Because there are so many engines to choose from, I have roughly the following ideas:

The first one is also the most common cooperation plan in the current international cooperation. For example, I cooperate with a certain engine production unit and promise to purchase how many engines from them, and they need to send the complete set of this engine after I reach the purchase amount. The technology is transferred to our company and helps us form production capacity.

In this way, because our purchase volume is relatively large, we can get the engine at a lower price. Later, when we have our own engine production capacity, we can further reduce the cost. However, considering the western technology of our country Blockade, I personally think we can only find a way from Ukraine or the old Maozi..."

Xia Pingyue nodded subconsciously.

This kind of cooperation plan is indeed very common, especially in the procurement of international military equipment. For example, country A says to country B, "I will buy XX fighter jets from your country, but you will carry out a full set of technology transfer", which is very routine. Now it is said that it is very difficult for Da Mao and Er Mao, and they are very short of money. From this perspective, it seems that as long as Zhang Qihang's order is large enough, at least from a technical point of view, from Da Mao or Er Mao's Is it really feasible to obtain a turboprop engine of this power level?
In addition, from the perspective of military sensitivity and political sensitivity, this 1000-horsepower turboprop engine is basically used in light civilian aircraft, and the sensitivity of technology transfer is very low...

Thinking of this level, Xia Pingyue suddenly felt a little weird: In this way, no matter from the perspective of technology or sensitivity, Huateng Industrial Group may obtain the manufacturing of turboprop engines with 1000 shaft horsepower. Technology, or even the formation of production capacity?
Zhang Qihang didn't notice the change in Xia Pingyue's expression, and he continued, "As for the second option, it is to purchase the finished engine from Honeywell or Pratt & Whitney Canada."

Speaking of this, Zhang Qihang sighed: "I have to admit that although Maozi goods are cheaper, the engines produced by these two companies are still more reliable than Maozi goods in terms of reliability, maintenance cycle and engine life. Yes, if users who modify the engine choose higher reliability and service life, and can afford a higher price, we can also provide them with a plan to switch to TPE331 series or PT6A series engines.”

"Well, the problem with the engine is really not that big," Xia Pingyue agreed with Zhang Qihang's statement: "But what about the modification plan? You seem to be planning to buy An-2 from Antonov Design Bureau to modify An-3 A complete set of technical solutions? Have you ever thought about what to do if the Antonov Design Bureau doesn’t sell it, or sells it to you at a high price that you can’t accept?”

When Zhang Qihang heard this, he laughed immediately: "Second uncle, you think highly of the technical content of the Yun-5 transport aircraft...Let me put it this way, if the Antonov Design Bureau is smart enough, then they should think about using their based on this plan, seek to cooperate more with us, but if they are not smart enough...

Although our country's aviation industry is not very developed, it is still able to independently design an aircraft. Chengfei even modified the J-7 so that even the old man can't recognize it. If we spend money, please ask the relevant units to help us Given a complete technical modification plan, will there be any problems from a technical point of view? "

"..."

Xia Pingyue thought about it carefully, and this is really the case. Although he didn't know the J-10 under development at his level, he still knew the J-8 and the recent J-8II on both sides of the fuselage. I also know that our country has launched an improved J-7 that does not know how many versions, so here comes the problem, since we can even provide countless improvement solutions for supersonic fighter jets, then give a maximum flight speed of more than 200 kilometers, cruise Is it difficult to give a replacement plan for a biplane light transport aircraft with a speed of only more than 100 kilometers?
Surely not difficult!

All that is missing is time.

Thinking of this, Xia Pingyue suddenly had an idea: "Since this is the case, why do you still let the old man earn money? Isn't it good to cooperate directly with Cheng Fei? With Cheng Fei helping you talk, the modification license of this Yun-5 is not yet available. Isn't it just a matter of one sentence?"

Ok?
Zhang Qihang felt that Xia Pingyue's suggestion seemed reasonable, but he always felt that there seemed to be something inappropriate, what exactly was inappropriate...

"What's wrong? Is there something inappropriate?"

Stopping Zhang Qihang, who was frowning and thinking, Xia Muqing asked in a low voice, who hadn't said much.

"That's not true," Zhang Qihang shook his head, and didn't say that he was thinking about when Antonov Design Bureau would obtain the airworthiness certificate and production certificate for An-3. With some clues, he nodded and said: "Second uncle, what you said is also reasonable, but what I am worried about is that the overall economy in Ukraine is very depressed now. Since the economy is in a recession, it is impossible for the Antonov Design Bureau to Given too much financial allocation, in this case, will the Antonov Design Bureau speed up the promotion of this project to ensure that they have external funding?
With the strength of the Antonov Design Bureau, as long as they make up their minds to allocate funds to this project, they should be able to complete the design of the An-3 transport aircraft soon, right? "

Ok?
Xia Pingyue really didn't think about this problem before, he just subconsciously thought that "the fat water will not flow into the fields of outsiders", but now he heard what Zhang Qihang said, and he also understood Zhang Qihang's meaning: if the Antonov Design Bureau wants to To form its own hematopoietic ability by refitting the An-2 transport aircraft with a turboprop engine, the huge An-2 transport aircraft modification market in foreign markets may have no chance with Huateng Industrial Group.

Thinking of this, Xia Pingyue couldn't help feeling a little embarrassed.

It was Zhang Qihang, seeing the embarrassment on Xia Pingyue's face, he changed the subject and asked, "By the way, Second Uncle, I forgot to ask you just now, what did you want me for?"

exactly!
Only then did Xia Pingyue realize that the reason why he contacted Zhang Qihang through Xia Muqing, his niece, was because he had something to discuss...

Thinking of what he wanted to say, Xia Pingyue couldn't help blushing, and asked bravely: "Qihang, let me ask, can your training helicopter...can you provide a batch for our military region?"
