The Grandmother in the Siheyuan

Chapter 215: Getting a Plane

The chief engineer looked at Liu Hua, then looked at the blueprint and shook his head: "No, it's not that I look down on Engineer Liu, but he is too young and looks like a college graduate."

Liu Hua looks young, which will be very popular in the future society, especially among women. However, in scientific research now, it is always easy to cause unnecessary misunderstandings. After all, this is a job that requires experience.

"Not young anymore." Liu Hua said with a smile, "I'm also over 30."

Team leader Li asked with a smile: "Chief Engineer, don't you think the name Liu Hua is familiar?"

"Liu Hua?" The chief engineer frowned and thought for a while: "I remember one thing. More than ten years ago, someone proposed PLC and developed a computer. The person was also named Liu Hua."

"That's Engineer Liu."

The chief engineer nodded and said, "That's not surprising. With your research in semiconductors, you may not be bad when it comes to radar."

The chief engineer looked at the blueprint and said, "This multi-pulse radar of yours should be the Doppler pulse radar commonly used internationally now."

Liu Hua shook his head: "I don't know what the Doppler pulse radar is internationally. This is just my assumption. If it is similar to the Doppler pulse radar internationally, any similarities are purely coincidental."

The chief designer nodded and said, "That's right. They kept it highly confidential to us. How do we know what Doppler pulse radar is? We only know the basic principle. This is very important. It is not only helpful to our Y-10 project, but also to our country's air force."

Team leader Li asked tentatively: "How about you give us a note and we can build this radar as quickly as possible to conduct experiments."

The chief engineer nodded, then covered his forehead and said, "I always feel that there is one more thing. Liu Hua's name is not only PLC and computer, but also something that I feel very familiar with."

So he wrote the note while thinking hard, and after he finished writing the note, he remembered it.

The chief designer slapped the table and said, "I remember that there was a man named Liu Hua who proposed to use our country's traditional lost wax process to make aircraft propellers and nozzles in the early 1960s."

Liu Hua nodded: "That was the idea I came up with when my grandfather and I attended a gathering of the older generation of military workers."

"This is a good idea. It will directly change our military production technology." The chief engineer smiled and said, "We have a deep connection. I have always had an idea, which is to deeply explore our ancient technology. I think there must be good things that we can use now."

Liu Hua nodded: "I think so too. After all, as early as the Song Dynasty, our country's seagoing ships had watertight compartments. The wisdom of the ancients cannot be underestimated."

Discussing ancient technology is a matter for the future. The most important thing right now is to develop multi-pulse radar.

The chief engineer picked up the phone and made several calls in succession. Finally, he said, "Tomorrow, a professional radar engineer will come. The most important task of your avionics department is to assist them in making the multi-pulse radar."

The 60* Institute in western Sichuan was selected. They specialize in radar and were established in the s. They later moved to Liangxi.

The chief designer of the Y-10 made a phone call and directly sent people over by military plane. More than a dozen engineers specializing in radar looked at the drawings and exclaimed in amazement.

"This is how the Doppler pulse radar is structured. I have never thought about it this way." "I had a similar idea before, but I rejected it because the structure was too cumbersome."

Team leader Li said cheerfully: "Engineers, according to the instructions of our superiors, four factories have been allocated to cooperate with production. Now I want you to review this drawing and make optimizations."

"Can we talk to the chief designer?"

Team leader Li pushed Liu Hua out and said, "This is the designer of the new radar, Comrade Liu Hua."

Team leader Li was quickly pushed aside, and more than a dozen mouths surrounded Liu Hua and began asking all kinds of questions.

Fortunately, the system gave Liu Hua all the knowledge instead of just a blueprint out of thin air. Some novels took a blueprint and claimed it was their own invention. Didn't he think about the rationality? Even playing basketball requires considering whether it is rational or not, let alone doing scientific research.

Liu Hua explained the principles and design concepts of radar to everyone in detail, and occasionally inserted some personal opinions, such as the future applications of materials such as gallium nitride and gallium arsenide.

After more than three hours of communication, the engineers from the 60* Institute were convinced. One of the oldest engineers said, "It seems that your design is already very complete. If there is anything else that needs to be changed, it can be put into production directly."

The four factories allocated their most elite personnel to cooperate with the project team in production, so the progress was very fast. In more than half a month, the radar had taken shape.

"This is definitely an unprecedented leap forward for our country's aviation industry and radar development." Team leader Li said excitedly as he looked at the radar already lying on the assembly table: "It's unprecedented. It's a pity that our military aircraft are not very advanced. Otherwise, with such a radar, no demons or monsters would be able to run rampant in our airspace."

Liu Hua was originally scheduled to be on this business trip for two or three days, but he was dragged here for nearly a month, waiting for the radar to be almost completed.

The Air Force specially sent out transport planes to move the radar to Jinling. We have to face the strait here, and the aircraft on the opposite side are more advanced than ours, so we urgently need a radar that can speak in Jinling dialect to equip the troops.

Liu Hua had no idea how to test the radar. After arriving in Jinling, he followed the 60* Institute to learn, helping to record and analyze data every day.

The test lasted more than half a month, and the overall performance passed all tests and far exceeded the Air Force's expectations.

On the day the success was announced, the Jinling Air Force sent a leader to personally entertain Liu Hua and his party.

The leader toasted Liu Hua with three glasses of wine, then held Liu Hua's hand tightly and said, "Thank you, Engineer Liu. We are under a lot of pressure right now. With your radar, we have at least more reaction time. You are our savior."

"You are the guardians of the blue sky, and I just did a trivial job." Liu Hua said with a smile: "Compared with you, I am still far behind."

"No, your work is great." The leader said with his hands on his hips, "You have made up for the shortcomings of the radar. Now we are short of an excellent fighter. I hope that you researchers will help us design a better aircraft so that we can protect the blue sky of our motherland."

Liu Hua could only laugh dryly and said, "You are flattering me too much. I am not a good major. How can I be that capable?"
