After the direction of the two types of engines was determined, Li Guocheng gave modification opinions, the first one modified the drawings, and the second carried out verification simulation.

In order to speed up the calculation, when Xiao Er starts the simulation, Xiao Yi will share most of its own computing power with Xiao Er.

This kind of work has lasted for half a month, and Li Guocheng has to put down his current work, because it is time for a large platform of precision machining 9-axis 5-linkage CNC machine tools.

When leaving, Li Guocheng ordered Xiao 1 and Xiao 2 to complete the simulation and material selection of the two engines.

7** factory that special workshop.

Li Guocheng, who was hoisted, devoted himself to the work of precision machining of large platforms, which was boring and boring.

This time, there were basically no onlookers, and the workshop was quiet except for the rustling sound of scraping.

A whole month passed, and the processing of the large platform was finally completed.

The team sent other deliveries, followed by Master Yi.

With the help of Master Yi, the assembly became fast.

Several operators in lab coats watched and sometimes helped deliver tools and workpieces.

Half a month later, when the last piece of skin was assembled in place, the installation of the 9-axis 5-linkage CNC machine was completed.

Power on and go to the car, and find some problems with coordination. Adjust the control parameters and solve the problem quickly.

The factory leader who got the news just arrived at the workshop with technical personnel and came up with a crankshaft formula with a complex curve, and Li Guocheng completed the preparation of the program according to experience.

When the start button is pressed, the machine runs smoothly.

The cutter head is automatically switched, and the cutter head continuously cuts the steel surface according to the curve.

"It's so smooth!"

"The surface is so beautiful, you don't need to test it, you can see that it meets the requirements with the naked eye."

"With such a large workpiece, the fixture is so light."

。。。。。。

In less than 1 hour, the crankshaft was machined, and the people around looked at the surveyor excitedly.

When the technician finished the measurement and gave a positive answer, cheers and applause suddenly came from the workshop.

The next day, the workshop was already full of factory leaders, military personnel, and ministry leaders.

When a 5 m diameter fan blade blank is placed into the fixture on the platform, the running section is automatically positioned and then the machining starts according to the program requirements.

Half a day later, a fan blade with a mirror effect appeared in front of everyone, and many engineers were excited to tears.

"In the past, it took us at least a few months, or even a year, to process such components. Moreover, it needs to be measured and processed repeatedly, and the final processing accuracy is far from meeting the requirements."

"Yes, look at this mirror effect, look at this beautiful curve, we are finally able to machine high-precision complex surfaces."

An engineer actually climbed onto the blade of a fan and wanted to kiss it.

Everyone around them watched them silently, most of them with tears in their eyes, and none of them laughed at the gaffe engineers.

A solemn internal celebration meeting began quietly and ended quietly, without alarming the outside world.

After the meeting, Longhua Technology received all the final payment. At the same time, two orders were obtained, one in the urban area of Rongcheng City and the other in the mountainous area of Mianyang.

Since Lei has reached the final sprint stage, the two projects need to be postponed for half a year.

They also used this time to build special machine tools and make qualified large platform blanks.

Back in the lab, Li Guocheng rewarded everyone involved in the project, including the structure group and the software group.

This time alone, 50W was used for the reward.

For the next week, Li Guocheng stayed in Building 3 opposite, where Kyoto Tech's radar team had been fully transferred.

Because Building 3 has a larger site, more complete equipment, and a more private environment.

For many parameters, Li Guocheng had to run back to his personal comprehensive laboratory and ask Xiao Er to help analyze and simulate.

After more than one month of parameter correction, the airborne radar of the Z-7 was successfully developed, and a comprehensive jamming experiment was carried out in the EMC laboratory, and the multi-band pulse radar has a very strong anti-jamming ability.

In fact, what is even better is the on-board computer, 4 i1 CPU special motherboards, which realize fast adaptive demodulation, fast Fourier transform, and power density spectrum analysis.

It is possible to capture targets in a very short time and track 10 targets at the same time to carry out precise strikes on targets.

For this algorithm, Li Guocheng carried out the architecture design, Kyoto Institute of Technology carried out the module design, and the code was completely implemented by Xiaosan.

The reason why Xiao San was directly used was mainly because Li Guocheng now had a sense of urgency and had to increase the speed of design.

When designing software, Li Guocheng introduced the concept of software reliability design.

Make the software run more reliably, the communication more stable, and the tracking target more accurate.

In the past, the communication channel they designed was often disconnected, Li Guocheng not only strengthened the EMC anti-interference design in the hardware, but also strengthened the reliability design of the software interface, and after the trial, the stability of the communication channel was ensured.

This made these academics a treasure, and these students later spread these design concepts to various units.

Li Guocheng did not participate in the field test, because the time for car design was running out, and he could not break his trust with Song An.

The engine and gearbox have been designed, and in order to obtain the optimal control curve, save fuel, and speed up quickly, Li Guocheng introduced the engine control microcomputer.

WITH AN ECONOMICAL BODY APPEARANCE, LI GUOCHENG COMBINED THE LATER BMW 5 SERIES AND VOLVO S90 TO DESIGN A NEW MODEL THAT SURPASSES THE CURRENT WORLD MAINSTREAM.

The sporty exterior of the car, referencing the Wrangler JEEP, has a cool appearance that satisfies him.

Considering the lack of production capacity of the other party and the lack of industrial workers, Li Guocheng wrote a complete document on the raw materials, production, inspection and installation of each component in detail.

In order to be more intuitive, a 3D assembly schematic diagram was drawn for the main modules.

And more than 1,200 process documents have been designed, as long as you are a junior high school student, you can produce the required modules by looking at the documents.

For the core components, Li Guocheng made a phone call to Song An and asked him to assign people to the laboratory, and Master Yi personally taught them production and assembly.

In order to help Song An create a perfect product that transcends the times, Li Guocheng simply spared no effort.

After receiving Li Guocheng's call, Song An was overjoyed. After going back, he was worried that Li Guocheng would release his pigeons, and when he received a call, he finally let go of the stones in his heart.

Recently, he has also been under more pressure, the factory has been put into construction, basically using all the money owned by the family, and most of the money is bank loans.

For a few months, there has been no news, and there has been news in the family that is not favorable to him, it is not that the old man supports him, it is estimated that he has already called Li Guocheng to ask.

He insisted on not calling, just to leave a trusted image for Li Guocheng, and he didn't want to be looked down upon by Li Guocheng.

As for the old man, who has always been cautious, why he supports this project so much has something to do with the old man's strong network.

Song An put down the phone and settled Uncle Shen to help arrange the technician, and he himself couldn't wait to rush to Kyoto.

Thank you all for your support!! Ask for recommendations! Ask for a commuter pass! Ask for a review!

Thank you very much for your support, the generous monthly pass and recommendation ticket make me warm
