Chapter 167 Mr. T (Part 1)
Early the next morning, Guo Tailai took his parents into the campus for a tour, took them to the bank, withdrew 20,000 yuan, bought some vegetables at Zhaolan Courtyard, and the family returned home again.
Ding Yumei began to plan what to buy, Guo Jianjun and Guo Tailai could only help and wait for orders. Fortunately, after noon, a car came to pick up Guo Tailai.
Along the way, Guo Tailai was still a little apprehensive, and had to give lectures to a group of experts, which Guo Tailai, who had just graduated from university, had never experienced before. He hasn't even experienced a few professors in his graduation defense, let alone such a scene?
Fortunately, Fatty still has a big heart after all, and he decided to explain only A200-related matters. Before the car arrived, Guo Tailai was already very calm.
Lu Zhiming has already completed the surveying and mapping of the secondary engine, which has also been approved by Guo Tailai. It is estimated that the experts from the Southern Group have been working for a period of time, and they came to explain, maybe they encountered a problem-focused discussion.
The fact is exactly the same. Although both Zhao Yanyan and Guo Tailai were sent to the Northwest Military Region for control, the technical information they left behind is still extremely useful. Guo Tailai has no clue yet, but Zhao Yanyan is a scientific researcher with good habits. Everything she does is recorded, as long as she accepts it, she can start researching from the beginning.
When Guo Tailai and Zhao Yanyan were in control of the military camp, they had thoroughly studied the design of Zhao Yanyan's rocket engine and the flight control software compiled by Zhao Yanyan. Except for the integration of the latest navigator, new engine and propellant, other aspects of the content are not so esoteric to these experts who have been immersed in this weapon for many years, and even Zhao Yanyan's stuff seems to be different. Little is insufficient.
While waiting for Lu Zhiming's survey and mapping, a group of experts focused on optimizing Zhao Yanyan's rocket engine, integrated their latest research from all directions, and integrated a complete system in the shortest time and put it into practice.
Because there has been successful launch experience, the basic tests of the rocket engine are approved and executed at the fastest speed, including the entire system. Except for the sports launch vehicle, the speed of integration of other systems is simply astounding. .
What Guo Tailai didn't know was that half a month before his return, when Guo Tailai had just finished making those pistols, another rocket launcher test had been arranged at the Northwest shooting range.
This time it was to test the new rocket launcher of the Southern Group, which was tentatively named the A100 300mm rocket launcher. This test was a formal test. Launch more than one rocket, and the shooting accuracy cep will be re-determined according to the distribution of impact points. After the test is completed, it will be launched as a brand new rocket launcher to the market.
After the integration and optimization of many experts, the parameters obtained in the final test, the maximum range of the A100 rocket launcher is 110 kilometers, the minimum range is 30 kilometers, the horizontal CEP is less than 70 meters, and the vertical CEP is less than 100 meters without GPS pure inertial guidance. GPS + inertial navigation is used. The joint guidance CEP is less than 40 meters. With this range and accuracy, it can be called a missile directly.
Comprehensive weapon performance, all aspects of the tornado rocket launcher that hit Lao Maozi in all aspects, if there are people in China who have mentioned the possibility of introducing tornadoes before, these test reports will definitely be thrown to nowhere. We also have a rocket launcher with a range of 200 kilometers waiting for perfect testing. How can we care about such a weapon with a range of only 90 kilometers and such poor accuracy?
After the test was completed, the South Group made modifications to address some newly discovered problems. There were at most two more tests. In no more than two months, this new rocket launcher could be finalized for production. The Army has already placed an order for a battalion and is training just waiting for production to be delivered.
At this time, the second-level rocket engine for Lu Zhiming's survey and mapping was also completed, and the eyes of these experts naturally focused on the A200 rocket launcher.
Still thanks to Zhao Yanyan, the secondary rocket engine flight control system she developed has complete documents and materials, and now there are complete drawings, and the two rocket launchers themselves share the same launch system, so the Southern Group can't wait. I want to speed up the research work on A200.
Is there a more convenient way than directly asking the designer of the second-stage rocket engine than holding a blueprint for research? Since Guo Tailai was in the capital, it was an inevitable result for the experts from the Southern Group to find him.
Guo Tailai himself was also known as a special technical advisor to the Southern Group, so he couldn't refuse such an invitation, let alone Zhao Xiangbei personally invited him, so he had no choice but to agree.
Of course, the timing of Zhao Xiangbei's invitation was also well chosen. It was when Guo Tailai had no way to explain to his parents, and Zhao Xiangbei's appearance also gave Guo Tailai enough reasons. Guo Tailai has no intention of refusing to reciprocate.
The reason why he didn't notify on the phone was because the mobile phone number Guo Tailai used was not confidential enough, so Zhao Xiangbei made a trip in person.
Experts from Nanfang Institute, some know about Guo Tailai, some don’t, but today Guo Tailai was personally invited by the chairman. Whether they know it or not, they have maintained enough courtesy to Guo Tailai. contempt. These researchers are relatively simple-minded. Whoever can make a rocket engine with a range of 200 kilometers is worthy of admiration.
Guo Tailai himself also showed humility, he didn't dare to pretend to be big, just said to discuss with everyone. This attitude is more pleasing, and then a group of experts discussed technical issues with Guo Tailai for a whole afternoon plus an evening.
In terms of mechanical processing, Guo Xiaopang is definitely an expert among experts. Guo Tailai can answer any questions about mechanical processing perfectly. On the contrary, Guo Tailai has no technical reserves for some aerodynamic problems of the corresponding rocket engine, so he can only use Zhao Yanyan's design to prevaricate.
After consulting the experts, they finally knew the basics of Guo Tailai's technology, and the second-stage rocket engine was indeed improved on the basis of Zhao Yanyan's. There were not many modifications involved in aerodynamics, and most of them were mechanical improvements. For the second-level design, everyone's problems still focus on processing and assembly.
Anyway, after a discussion meeting, the Southern Group has obtained a complete assembly process. Even the torque of each screw and the number of turns are clearly marked. This step alone is enough to save at least several months of production process design. Even the parameters of the A100 can be adjusted better.
To be honest, so many experts worked together to optimize and integrate the entire system to increase the maximum range of the A100 from Zhao Yanyan's 107 kilometers to 110 kilometers. Among them, the processing and assembly of the engine accounted for at least 50% of the influence. .
