Chapter 772: Customer Vs Supplier

Mahmoud listened to the explanation very carefully, but this time the explanation was a bit long, Song Wenhua spent a full two hours.
After listening to the explanation, it took a long time for Mahmoud Shen to speak slowly: "Master Song, your plan is very attractive. If you follow the plan you just stated, the performance of this fighter can indeed be greatly improved. But I have a few questions."
"You said." Song Wenhua has always attached great importance to the opinions of customers. He took out a small notebook and began to record.
"First, if I understand correctly, a brand new X-band Doppler multi-function fire control radar will be installed on this fighter, but you don’t have any off-the-shelf products for this radar. Although I guess, this one The radar is probably related to the new technology you got from Isaac this time, but can you guarantee the time? As far as I know, for you Huaxia, this is a radar with a brand new system. Regarding its progress, I have reservations for now."
Tan Zhenhua just wanted to explain, he was stopped by Song Wenhua's eyes. He nodded lightly and replied in a deep voice, "Mr. Colonel, regarding this radar, since you and Mr. Ben Fang from 4014 Institute are also old friends, you are not as good as you. Find a time to ask him, I believe you can get a more accurate answer from him."
"It turns out that this radar will be in charge of 4014." Mahmoud said in a slightly exaggerated tone: "Master Song, from the perspective of a customer, I think you can do this long ago."
Tan Zhenhua obviously saw Song Wenhua stiffen, and couldn't help but feel secretly happy: Look, you can't stand the problem with the food protection of the third machine department, right?
But Mahmoud obviously didn’t mean to entangle on this issue anymore. Instead, he continued:
Well, I’ll look for a chance to talk to Master Ben again. Then I’ll say the second point, in your current plan. In, a large number of avionics products of the British Marconi Company are used. I know that these avionics products have been installed on the "J-7M" that you are currently developing. The reliability of the future should be certain. But, I want to know whether these avionics systems will have some unpredictable usage or supply problems. Master Song should understand what I mean, right?"
The words were vague, but the three people in the room knew what Mahmoud was talking about.
Because, in the Second India-Pakistan War, the Pakistan Railway was almost unarmed because of the ban on rice-style equipment. The lesson was extremely profound. China has a soft spot for these relatively backward weapons and equipment. In addition to the fact that China's goods are really cheap and can withstand battlefield consumption, it is also an important reason that China has never attached any political conditions.
But if British Avionics is installed in China's equipment, will this be a problem?
"Mr. Colonel does not have to worry at all," Song Wenhua replied: "Of course we know your dilemma at the beginning, and this is one of the lessons that must be learned for us in China. To this end, we have also taken many measures. On this aircraft, we can provide multiple guarantees. First of all, avionics are not weapons or ammunition and are not consumables. Except for a few vulnerable parts, there is no need to worry about consumption; secondly, we purchased from Marconi There are a large number of avionics products, and a special spare parts library has been established for more vulnerable parts, so you basically don’t need to worry about parts loss; finally, our cooperation with Marconi is multi-faceted, including their support. China’s avionics is localized, and China’s electronics industry level and localization capabilities are believed to be understood by Mr. Colonel. When this fighter can really fly into the sky, it is very likely that all China’s products can be used."
Mahmoud nodded and said: "If that is the case, it would be better. From my personal point of view, compared to the British products may be a little bit more advanced performance, I would rather use China's sub-system, this is a weapon, the soldiers will go on. The partner who needs to entrust his life after the battlefield needs to be fully trusted by those who hold him, instead of worrying about whether it is worthy of trust at any time."
Song Wenhua nodded again to agree with Mahmoud's point of view and asked: "Colonel, are there any more?"
"Yes." Mahmoud said: "As far as I know, the fly-by-wire control system has not been used on any known China fighter aircraft, and on this fighter aircraft," he pointed to the drawing. The plane on board said: "The double-redundancy fly-by-wire control system is used. I must confirm its reliability."
"Let me explain first. In order to make this "Super Seven" have better flight capabilities, the use of fly-by-wire control system is actually a necessary choice." Song Wenhua replied: "Because of the expansion of the flight envelope and the high-G capacity. Overloading must relax the static instability, which will make the fighter more agile and harder to control, and the complicated weapon system will also occupy the pilot's more energy, and these are not traditional manual-mechanical-hydraulic control It can be matched. According to our tracking of international advanced technology, the use of telex control is the general trend. Of course, Mr. Colonel, you have also seen it. We will reserve a part of the mechanical control system for this fighter plane. This is done for safety. Redundant backup."
Mahmoud thought carefully for a moment before he said: "Master Song, I accept your point of view. However, I hope that if our Pakistan Railway participates in the development of this aircraft, our test pilots can participate in the whole process."
Song Wenhua nodded and said, "No problem, I can take charge of this matter and promise you now."
"Then about technology, I have one last question." Mahmoud said: "It's the engine, I'm afraid Chief Song also knows that since our Pakistani Railway equipped your "J-6", we have been working on this matter. headache.
Well, it's not only Mahmoud's headache, Song Wenhua hurts all over his body when he mentions the engine...
But for a fighter, the engine is another hurdle that cannot be passed.
Song Wenhua had no choice but to say: "There are now three solutions, the most conservative is to use the engine currently adapted to the "J-7". The latest modification of the "Turbojet 7", the "Turbojet 7B B" has passed our China National Appraisal. , The first turn can be 200 hours, and the full life span is 600 hours; the second plan is to adopt the new hair we are researching. The design performance of the new hair is more than 15% higher than that of the "turbojet 7", and the life expectancy can be increased by 30%. Of course, I can’t guarantee when the new post will be available.

Mahmoud said quietly: "Song always said that there are three solutions, but I only heard two."
Song Wenhua pointed at Tan Zhenhua, who had been silent for a long time and said, "Is this the third plan? Ask your good brother."
