Chapter 1456: New plan (9)

So, as the saying goes, being rich can make you feel better...
Tan Zhenhua waved his checkbook to invest in various basic research fields. While fully ensuring that these projects will not be interrupted due to lack of funds, he also avoided a lot of unnecessary personnel scrambles and aroused the full enthusiasm of research participants. After all, most of China's scientific research workers are relatively simple. What they hope most is a clean and pure scientific research environment that does not contain too many complicated interests and a simple way of distributing income according to labor and results. Under the circumstances, they can maximize their ingenuity.
Just like the DD6 blade in my hand.
In Tan Zhenhua’s previous life, this blade was developed in the late 1980s, and it was not until the turn of the century that the verification and development of materials was finally completed. However, the actual solution of the process manufacturing process problems and put into mass production is already entering the new century. Thing.
And in its first real installed user-WS10 "Taihang" engine, there have been many situations, including the material problems of the blade itself, the production process, and the coordination with other parts. The problem is that the "Taihang" engine has been in a state of very unstable quality for a long time. The accidents of "spraying parts" have occurred many times, so that it is forced to "return the technical status to 0". At that time, China had selected this engine as the standard power for the domestically-made improved "Su-27" and J-11B, which once led to the production of a fighter jet without an engine to install, and it was widely spread on the military network. The photo of "Chrysanthemum Can" is a true portrayal of this special time period.
But in this time and space, these should be avoided to the utmost extent.
Tan Zhenhua holds the DD6 in his hand and thinks that the research and development of these advanced parts will receive his long-term and stable investment. Some parts and the latest manufacturing technology are more likely to be first applied to the "Speey" and a series of modified engines. Carry out application and verification, after accumulating enough running time to fully expose possible various problems and find a reliable solution, will it be applied to the latest engine model. This aspect is gradually changing the old engine and the other aspect. The method of advancing the new aircraft will make the development process of domestic aviation development smoother and more orderly, and the accumulation of technology will have more continuity.
Engineering scientific research is a rigorous science. The success of any complex system inevitably comes from the precise collaboration of various fields and links like gears. Talented academic leaders are very important, and the accumulation of countless trial and error is even more important. Thinking about overtaking in corners every day is what Wen Xuan loves to boast. The hard-working engineers in the vast engineering and scientific research fields are disdainful and have no time to bother about such unrealistic fantasy.
Thinking of this, Tan Zhenhua reluctantly put the DD6 back into the safe, but was immediately squeezed into a heavy steel ingot in his hand, and the second young master’s arm sank.
Cai Qigong’s voice sounded again: "Mr. Tan, this piece of ultra-high-strength low-carbon alloy steel with a yield strength of 785Mpa in your hand now, the national label is 980, it is an iron base with an appropriate amount of nickel added. , Chromium and titanium alloy."
"980 steel?"
"Yes, 980 steel has high strength, high toughness, good welding performance, seawater corrosion resistance, and good shipbuilding process adaptability. It is suitable for submarine pressure hulls, deep submersible lifeboats, large surface ships, aircraft carriers, tank bridges, Supersonic wind tunnels and other engineering structures that require high strength and toughness." Cai Qigong said: "According to the performance comparison test we have done, the comprehensive performance exceeds the metric HY-100 steel, and the yield strength of HY-100 steel is not less than 686Mpa At present, it is the steel used for the flight deck and main structural parts of the metric "Nimitz" class aircraft carrier, as well as the steel for its advanced nuclear submarine. Our 980 steel is slightly higher than HY-100 steel in terms of yield strength index. The successful research and development of the
A
can add a higher performance option to our country’s ship steel. Mr. Tan and the navy are very much looking forward to it!

"I'm looking forward to it too." Tan Zhenhua smiled while holding the steel ingots: "Dean Cai, the deck steel you helped me with back then can only be regarded as temporary. Now this 980 steel is the final solution."
Cai Qigong was stunned when he heard the words, thought about it, and asked tentatively: "Mr. Tan, are you planning to use this steel to build a ship that can fly planes on it?"
It is said that Academician Cai Qigong was very impressed with the first meeting with this President Tan, and was stunned by his whimsical idea of ​​"flying on a freighter"-but now he also knows it. It is indeed possible to fly a plane on a freighter, and the Iron and Steel Research Institute took this opportunity to start the in-depth cooperation with Tan Zhenhua that has continued to this day.
"It's not a freighter this time." Tan Zhenhua replied with a smile.
Cai Qigong's heart was "flickering", and his thoughts suddenly appeared...
However, looking at the meaning of Tan Zhenhua’s words, although he made explicit hints, he just refused to expose the layer of window paper. Since Academician Cai has been able to hold the position of the dean for so many years, he is naturally an old man. Knowing that there are some things that cannot be said clearly before the time is up, he immediately choked his curiosity in his mind, but after thinking about it for a while, he said: "Mr. Tan, if that is the case, you have to Solve a very critical problem."
"Oh? What advice does Dean Cai have?"
"That's it." Cai Qigong pushed his eyes on the bridge of his nose and said in a tone similar to advising friends: "We all know that no matter how good the welding is, it is impossible to obtain better mechanical properties than the material itself. Seams have always been the most vulnerable point of failure. Especially for flight decks that require very high flatness and mechanical properties, reducing the number of welds is more practical."
"and so?"
"Therefore, Mr. Tan, the development of 980 steel alone cannot completely solve your problem. The method you used on the freighter back then was temporary, and the durability of the material was not high. The "Sea Harrier" itself It is a single-engine, light aircraft with a weight of no more than 12 tons, and the impact force during take-off and landing is not large. We can reduce the requirements and use multiple small plates to weld together. But if you are in a larger size It’s impossible to do this on board of the ship.

"Ok?"
"You need a key piece of equipment, a 5-meter wide plate rolling mill."
