Chapter 831: The destination of Yunshi

"Yes, yes, but it's a little troublesome." Liu Da wanted to reply.
"how to do?"
"We can learn from the previous practice of the Americans and use a large aircraft with multiple engines, preferably four engines, for experiments, because the aircraft with multiple engines has a power redundancy design. Even if one less engine works, it can still ensure the aircraft's performance. Normal flight, this practice has a common name in the world, that is, "flying platform". Although the experimental altitude of the "flying platform" is generally below 11,000 meters and the flying speed is lower than 0.85 Mach, it can at least make up for us. It is a pity that there is no perfect and usable high-altitude platform, but for the crew piloting this "flying platform", there is a certain degree of danger."
Tan Zhenhua sighed for a moment and said: "This method can be tried, but we don't have such a plane in hand?"
The flying platform is not too unfamiliar to senior non-professional military fans like Tan Zhenhua. He has seen photos in his previous life. According to the information that has been made public, the "760" flight deck of Huaxia was modified with an "Il-76", but Tan Zhenhua vaguely remembered that Huaxia got this suitable one from Maozi." "Flying station", that's all in the next century, but now it's 1983. With the relationship between China and the Soviet Union still bad, where can he get an "Il-76" back?
"In fact, we have a ready-made flight platform." Liu Da thought: "It was refitted with a "H6". The refit was completed in 1971, and it has been used for 12 years. But the trouble is that because of the domestic Such a flight platform, so the mission is very heavy. It has been flying for another 12 years, and the body is very aging. Mr. Tan, you should know the whole life of the "H6" aircraft is only 2,000 hours. Therefore, this flight platform that has been flying for 12 years has basically reached the end of its life. Neither I nor Mr. Wu think it can withstand all the test flight missions of a new model."
"Uh...you guys don't plan to let me buy a "H6" from Xi'an Aircraft Factory, are you?"
As Tan Zhenhua asked, he felt that his little heart was beating "pounding". He said, "Well, who made this bad idea? I really want Xiaoye to buy a bomber."
Liu Daxiang and Wu Daguan looked at each other but didn't say anything-yes, Tan Zhenhua understood. These two must have discussed it early on, and they are complicit!
Buying a bomber...Why do you feel so confused when you think of this?
"Uh, is there no other plane to choose from?"
Liu Daxiang spread his hands and said, "This is really gone."
To be honest, Tan Zhenhua thinks that he has opened the door to buy a "H6" from Wang Qingping. As long as the purpose is explained, the possibility of realization is quite high, but it is a strategic bomber after all. Is this operation a bit frightening?
Is there any other way?
He activated his little head and began to ponder hard-a large aircraft with two engines is best with four engines. The power safety redundancy should be large, and the propellers are not enough. They must be jets...
Tan Zhenhua shook his fingers and counted for a long time. Except for the "Hang Liu", Huaxia really can't come up with such an airplane at present!
He just thought about agreeing to forget it, but at this moment, a thought suddenly broke into his mind, and then carefully calculated, hey, it seems, maybe, probably, it's really OK?
"Master Wu, Master Liu, Master Li, look, let's change our mindset and use that "Yun-10" aircraft that is currently flying on a test flight to make this "flying platform" okay?"
He asked carefully.
When he said this, everyone in the house immediately looked at each other.
Then, he began to explain his reason: "Look at the domestic passenger aircraft project, regardless of whether McDonnell Douglas continued or BAC turned positive, the already embarrassing position of this "Yun X" aircraft may be even more uncomfortable. I want to stop it. It’s a great probability, but it’s a pity to spend so much money to build an airplane that’s idle? And it was originally a 4-engine, so when it was originally designed, it must have reserved engine power redundancy, so according to Master Liu The prerequisites just now are actually quite suitable to be used as our "flying platform"."
Don't tell me, when his idea came out, several people in the house nodded slightly after thinking about it for a while. Obviously, they thought it was feasible.
This gave Tan Zhenhua the confidence to continue: "You think, although this plane has flown a lot of takeoffs and landings, although it has not completed all the test flights, some basic flight performances have been verified. When I heard back from both Chief Ma and Secretary Lu, they are actually quite confident in its safety, or would they not dare to drive it to deliver food to Harbin? Right?"
Several people in the room whispered for a while, and finally Wu Daguan said, "Zhenhua, what you said seems to make sense, but none of us are engaged in airplanes. We are not sure about this. Or, let's ask Lao Ma. ask?"
Just do what you say. Several people who are resolute and vigorous, immediately began to call everywhere to inquire about the whereabouts of Ma Fengshan. Recently, it was the day when the "BAC" production line started trial operation. The people of Ma Fengshan must be in Xijing, just not Know where he is busy now.
Soon, the person was found, and as soon as Ma Fengshan heard that this was the case, he immediately agreed to put down everything in his hands and rush over.
After waiting for a while, when people arrived, Ma Fengshan in the turmoil didn't even have time to sit down and said, "I agree with Zhenhua's opinion. I think it's okay to change the "Yun Ten" to the "Test Platform"."
Liu Daxiang hurriedly said: "Master Ma, we all know the relationship between you and Yun Shi, but what we are discussing now is purely technical. You can't mix in personal emotional factors!"
Ma Fengshan suddenly said with a stern face: "Old Liu, who do you think of me, Ma Fengshan, I only say that from a technical point of view."
Wu Daguan said: "Master Ma, then you tell us?"
Ma Fengshan nodded, then sat down, sorted out his thoughts a bit, and began to explain: "Technically speaking, the main problem of this YX-10 is the lack of structural strength and non-standard process flow. This is also the case before it. The two most criticized. As its chief engineer, I have also reviewed the reasons. The lack of structural strength is due to the excessive size of the load-bearing structure of this aircraft and the high processing accuracy requirements. China has not been able to The equipment for processing such parts can only be processed into small-size parts and then welded and spliced. The structural parts produced in this way are difficult to control weight and have a great influence on the strength of the internal structure; but the process flow is not Standards have led to poor standardization of parts and components and difficult maintenance and support."
After talking about the two deadliest two, he turned his face to look at Tan Zhenhua and said: "There is another one, which Zhenhua reminded me last year. The "Yunshi" is a four-engine mid-sized passenger plane, which competes in the civil aviation industry. In the fierce today, the inherently high fuel consumption of this kind of aircraft has made it more and more unwelcome in the commercial market where economy is particularly important. These three major defects are the objective reasons for the failure of the "Yun 10" project, but-"
When he said this, he looked around at the people in the room who were listening attentively, and said in a very positive tone: "If you want to change "Yun Ten" to "Flying Platform", then none of these three problems will exist. ."
Wu Daguan asked, "Why? Let's put aside the issue of fuel consumption. The first two questions are real. Can the natural problems be cured?"
"Of course," Ma Fengshan said confidently: "First of all, regarding the strength of this structure. "Yunshi" was originally designed according to the passenger plane standard for carrying 150 passengers, so it must be reserved within the prescribed take-off weight. The space and weight for passengers, which caused us to limit the weight of structural parts when designing-that is to say, the current state is already the limit at which we can strengthen the structure of the aircraft, but It’s not the same if you use it as a "flying platform". The weight you have to carry will definitely be much smaller than 150 people, right? Although the large-sized structural parts welded with small-sized parts do have safety risks , But, we can do structural reinforcement on this basis? Anyway, there is no need to carry passengers, so the aircraft does not need to consider the comfort and load of passengers. You can remove all the accessories such as tables, chairs and benches in the cabin. Well, the weight of the experimental equipment is set aside, and the other weight can be allocated to the reinforcement structure. In fact, I have already considered it. As long as it is allowed to add a few tons of empty weight, then this problem will not be a problem. Up."
This statement of his was immediately approved by everyone, yes, don't carry so many guests, why do you need those bottles and cans? It is enough to install the experimental equipment, which is much easier than 150 passengers plus luggage.
Ma Fengshan continued to chase after victory: "Secondly, regarding the poor interchangeability of parts caused by the non-standard process flow-this is even more okay. For this single seedling, what interchangeability should we consider? All maintenance parts, Can’t it be tailor-made? The protection of large fleets and multiple airports can’t be done, and the protection of a single aircraft at a single airport can’t be done? My production line also has an aircraft that is more than half assembled, even if it’s all disassembled and repaired. It’s good enough for this one as an accessory, right?"
Everyone thinks, is it really like this? This method is definitely not suitable for civil aviation, but for this single seedling, isn't this method effective and easy to use?
Ma Fengshan said again: "The last question is about the fuel consumption of a four-engine aircraft-not to mention that the flight platform should have a four-engine aircraft in order to ensure sufficient safety and redundancy. For the burned Jinshan Yinshan, what does that little oil money count?"
