Chapter 182 Mutation
Based on the existing material data and the maximum overload value she derived, Wu Tong deduced step by step, selected the direction, and screened out the wrong options...
In the end, Wu Tong obtained a special type of steel.
According to the predicted data, its maximum overload capacity will be about three times that of current aviation steel. It has excellent tensile resistance and heat resistance. Even under extremely high speed and high temperature conditions, it can still maintain strong mechanical properties, which is sufficient to meet Wu Tong's requirements for new missile materials.
Based on this, Wu Tong also deduced a variant direction, which has strong toughness, tensile resistance and corrosion resistance. The predicted cost will not exceed the current cost of ordinary steel, but it has the special ability to withstand at least a magnitude 7 or 8 earthquake.
Many places in the country are prone to earthquakes, especially Sichuan, Qinghai and Ningxia. Wu Tong made special marks in this direction, preparing to further deepen the derivation and then promote it to higher authorities.
After the material model was designed and the preparation process was roughly deduced, Wu Tong needed to arrange a laboratory to start the new material experiment. The 624th Institute was not specialized in materials, so Wu Tong simply asked the teacher for help and conducted the experimental preparation at the Peking University Institute.
"No problem. Your senior brother is also in Beijing. I'll ask him to assist me! I'll report to you after I give you the experimental data and the situation reflected in each step and complete the experiment!" Old Cheng agreed without hesitation.
The Peking University Materials Laboratory that he is in charge of is definitely one of the top materials laboratories in the country. There are few places that can compare to it, and he is confident of this.
He guaranteed to complete the task entrusted to him by Wu Tong.
After reporting the safety, Wu Tong sent the derived data and preparation plan to the teacher, and waited for Cheng Lao's experimental summary data to be sent over. Based on this, he continued to derive more refined experimental parameters to improve the preparation process.
This cycle was repeated three times and took a week until she produced a special steel material, MC4, that met her expected data.
Wu Tong was not at the preparation site and could not supervise the changes immediately, so he had to use this more troublesome method.
This method is the material preparation process that Cheng Lao is familiar with. It is a rare miracle that Wu Tong can be formed in one go. The process is perfect and it will be put into production immediately.
624 has a special military factory that is responsible for processing and producing missiles. The absolutely trustworthy person in charge, Engineer Xu, is also a technical person. With the introduction of Hua Yanxing, Engineer Xu came to 624 and met Wu Tong.
"Mr. Xu, thank you for coming all the way here!" Wu Tong shook hands cordially with Mr. Xu who came to hand over the documents.
"Thank you, Mr. Wu, for trusting us with this important task!" Engineer Xu was excited to see the new special steel with excellent data. He has always been looking forward to technical innovation.
After a brief greeting, the two immediately got down to business.
"The new type of missile has relatively high requirements for the overload of materials. In collaboration with the Peking University Laboratory, I have developed a special steel material MC4 for the new type of missile. It is expected to increase the overload value of the current material by three to four times to meet the new type of missile's requirements for new materials." Wu Tong and Engineer Xu carefully sorted out the preparation process, understood the current situation of the factory processing line, and discussed improvement plans with Engineer Xu.
"···High-temperature reactors require higher temperatures····Steel must be shaped in one go··"
It took two days for Wu Tong and Engineer Xu to complete the details of the technical innovation of the current production line and sort out the various nodes of the MC4 preparation process.
"Boss Wu, you are this!" Engineer Xu was very successful and gave Wu Tong a thumbs up before leaving. The genius's brain is indeed different from that of ordinary people. He was able to deduce such a sophisticated preparation process without being on site. Old Xu was convinced these two days.
Engineer Xu patted his chest and made a promise: "I will go back and arrange the upgrade of the production line. Mr. Wu, wait for my good news. I will never hold our project team back!"
"I'll leave everything to Mr. Xu!" Wu Tong bowed slightly in thanks.
As the processing of the missile body was underway, the manufacturing and assembly of the scramjet engine was also coming to an end. Thanks to the continuous efforts of several core engineers and workers, all the components were finally formed and the final assembly was completed before the end of January.
Wu Tong and Hua Yanxing performed the final checks bit by bit and announced that they could begin the most critical field test of the engine.
At 8:00 a.m. on January 31, the scramjet engine test began, and the fuel N24 had been loaded into it. The counterweight was in place, and everything was ready.
Wu Tonghua and a group of core engineers at Yanxing gave the order to start. The engine roared, and red flames spewed out from the nozzle, which seemed to make the crowd of onlookers feel its awe-inspiring temperature.
Success!
The word "success" flashed through everyone's mind, excitement appeared on everyone's faces, and cheers almost resounded throughout the entire laboratory.
"Attention all departments, pay attention to the recorded data!" The successful launch can only be said to be a preliminary success, and it still depends on the specific data feedback.
Wu Tong was happy, but he did not forget to give instructions. At the same time, he kept an eye on the nozzle to see the compatibility of the new fuel and the scramjet engine.
The fuel of the air-to-air missile will basically burn out in about half a minute. After cooling down slightly, Wu Tong immediately went forward to check the condition of the nozzle.
"Fortunately, the cooling system has good adaptability and there is no sign of melting of the nozzle. The existing materials can barely hold up!" Hua Yanxing walked forward with Wu Tong and saw the nozzle with only slight burn marks. He sighed with relief.
This is another major hurdle that has been overcome. The foundation of the new missile has been laid, and she seems to be able to see the birth of PL-15 in the near future. With the help of various excellent scientific research results, the performance of PL-15 is a visible transcendence.
Although this also means that the PL-14, which she researched, has not yet been officially put into production, it is already facing retirement. However, apart from feeling guilty about wasting national resources, Hua Yanxing does not complain. If the country can have better strike force, then it should not accommodate her outdated design.
Of course, her PL-14 will not be dismissed at once. After absorbing new technologies and optimizing and improving it, it will still have manufacturing value and can be used for fighter jets currently in service, so the scientific research funds will not be a complete waste.
Wu Tong pondered for a moment, "We still need to make a high-temperature resistant coating. If we add some auxiliary materials to the existing materials, it can be used in other places!" However, this data did not meet Wu Tong's satisfaction. For Wu Tong, this data was too reluctant. Sure enough, there were still omissions in the first version of the design!
"Mr. Wu, the outlet temperature of the engine combustion chamber is 3500℃, the inlet temperature is 1980℃, and the engine energy efficiency..." The data were reported to Wu Tong one by one. With the data substituting, Wu Tong's mind kept working.
"The cooling system also needs to be further improved!" The high-temperature resistant coating and the two-phase cooling system work together to solve the key problem of excessive engine temperature.
