Chapter 869

While Jiang Yanhai was talking to Professor Qian, the video conversation soon lit up. In about five minutes, the screen in front of Jiang Yan's sea lit up six pieces.

"Well, everyone has arrived. Boy, you can send us the design data of the engine you designed. If there is really a thrust weight ratio of 27... Even if the performance in other aspects does not pass, it will be enough for us to do it." old Liu said with some excitement.

These professors have been introduced, and Jiang Yanhai is also a little excited. These are the backbone of the Republic. It can be said that they are the leading figures supporting the whole sky of the motherland. These old professors, you don't know them at ordinary times, but without them, the country would not have so many advanced weapons and equipment.

Without these advanced weapons and equipment, even soldiers like Jiang Yanhai have no sharp weapon to kill the enemy if they have the heart to serve the country.

After greeting these old professors, Jiang Yanhai began to operate the tactical tablet in front of him and transmitted the completed test results.

"Xiaojiang, what tests have been done on the engine you designed? Did it start with the parts test?" asked an old professor surnamed Li, the oldest of whom is close to 80 years old and still a woman.

"Professor Li, no, I developed it in a private research institute, because the official research institute can't waste the national funds, so I directly designed it, then spent money to produce and assemble the whole engine, directly tested the components of the whole machine, and completed the 150 hour long test run." Jiang Yanhai said while transmitting the documents.

"What?! you have finished the 150 hour long test drive?" Professor Qian and other old professors were a little excited.

Jiang Yanhai nodded. To tell the truth, he was actually worried, because these people were not young, and the youngest was in his fifties.

It's not that there are no young talents, but these old professors are figures at the level of Taishan Beidou. Their confidentiality level is high enough. Such things are naturally handed over to these old professors for transmission at the first time.

"Come on, pass the documents to us." Professor Qian was a little excited, and the other professors were obviously a little excited.

It can withstand 150 hour test run, which proves that the engine has been very mature! You know, in previous years, none of the engines designed and produced in China can support 150 hour test run!

The file was soon transmitted. After all, the file is not big, but all the detailed data about the test. These professors are figures in aeroengine, and even many aviation school textbooks are written by them.

These things are naturally not difficult for them.

"President Zheng." Jiang Yanhai lowered his voice.

"What's the matter?" principal Zheng looked up at the screen, and then asked in a low voice.

"I think these old professors should pay attention to it in advance. They are old, if they are too excited." Jiang Yanhai hesitated and said his worries.

You know, when Professor Zhao first got it out, his blood pressure was a little high, and Professor Zhao was young.

Principal Zheng looked at the screen, and then whispered, "it's difficult for your boy to think of this. Don't worry. There are special people around them at any time, and there must be someone nearby, but you can't see it."

"Then I'll rest assured. Otherwise, if something happens to them, I will become a sinner." Jiang Yanhai breathed a sigh of relief.

"Don't worry, it's all right, and even if they don't know it, such a big event, for those scientists who have struggled for the National Aero Engine all their life, even if there is an accident, they should see it with their own eyes!" principal Zheng nodded seriously.

Jiang Yanhai also nodded silently. Although these old scientists were not soldiers and did not struggle at the forefront of the war, they also dedicated their lives to this country and nation on another battlefield.

Time passed little by little. More than ten minutes later, an old voice came from the screen with some excitement.

"OK... OK, OK! Heroes make teenagers! Heroes make teenagers!" Professor Li, the oldest, knocked on the table with an excited face. Her face was full of tears.

It seems difficult for others to understand, but I'm afraid only these old professors who have also struggled all their lives in the Institute and tried to hold up a strong umbrella for the sky of the Republic can understand.

"Don't get excited, sir. You're not in good health," another young professor, who was also in his fifties, said quickly.

"Yes, Lao Li, don't get excited. We old guys still need to see this engine installed on the eagle of our motherland." Professor Qian also hurried to say.

"Can I not be excited? How many years? Think of the technology we bought back from the former Soviet Union, and the engine life we manufactured was only 300 hours! 300 hours! You know, all the expenses in that era were saved by countless people through frugality!"

"But we couldn't even extend the engine life. At that time, the life of an engine in the United States could exceed 5000 hours, while we only had 300 hours! Almost one twentieth of that of others!"

"A fighter can hardly fly for long. We have to change the engine until we finally extend the service life to 800 hours."

"But even if it was only 800 hours, when our country's economy was so depressed, we had to mass produce it! Isn't it to support a safe sky for our land? Today we finally catch up... Catch up... I think I can't see this scene before I die." Professor Li said with tears.

At the other end of the screen, a girl in her twenties was silently wiping Professor Li's tears with a handkerchief.

"Xiaojiang." Professor Qian and other professors also heard that some of their eyes were red, but they were OK and could bear it.

"I'm here." Jiang Yanhai quickly stood at attention.

"Well done, well done! Where do you do this test? If there is no test place, come to the Research Institute of Taihang." Professor Qian said directly.

"There are places for other tests, but we don't have the high-altitude test bench. Maybe we really need to go to Taihang." Jiang Yanhai didn't hesitate, but spoke directly.

"If there are finished products, send them directly immediately, and I'll let other engines make way for you." Professor Qian said decisively.
