Chapter 862 The First One (12000 Monthly Tickets Plus More)

Fan Tianlei left, leaving Jiang Yanhai alone with a big suitcase.

Back in his dormitory, Jiang Yanhai was thinking about the things between himself and Li Ruobai all the way. The problem is that Jiang Yanhai is sure that he remembers everything, and he remembers everything that happened between him and Li Ruobai, including them He also remembered the agreement between them.

The problem is, I really didn't know exactly what Fan Tianlei was talking about.

Returning to his dormitory, Jiang Yanhai opened the box. When he took out the contents, Jiang Yanhai immediately fell in love with it. This is an exquisite model aircraft.

The model of J20, and this thing is definitely from the hands of experts, this should not be a model that costs two or three hundred yuan on the Internet, after a scan by the intermediate scanning system, all the large parts of its body can be removed!

Including the engine, if you want, all can be disassembled into parts, and it is composed of parts inside.

Of course, it can't really be the same material as the J20. Except for the three tires and the cockpit, all other parts should be made of alloys. Even the place where the rear parachute is stored can be opened. The umbrella bag is actually made of cloth.

This thing is quite delicate, and it is impossible to buy it without a few thousand dollars.

But...what are you doing for yourself? Although this big wife model aircraft is not bad, but brother is someone who can touch the real big wife at any time!

"Er Egg, can you retrieve the meaning of the chief of staff?" Jiang Yanhai asked in his mind with some doubts, but he really didn't think of it.

"There is no record in the database, can you search for Internet results?" Erdan asked immediately.

"Yes." Jiang Yanhai agreed directly.

About 30 seconds later, Erdan said, "After I searched the Internet, the chief of staff mentioned your relationship, and I searched for things that are taboo in love. It mentioned that there is a high probability that some important festivals should not be forgotten, such as Speaking of Valentine's Day, Tanabata, the woman's birthday..."

"Stop! What date is it today?" Jiang Yanhai immediately understood something when he heard the word "birthday".

"Today is May 30 in the Gregorian calendar." Erdan immediately gave the exact time.

When Jiang Yanhai heard this, he immediately understood that Li Ruobai's birthday was June 3, and there were indeed a few days left.

If Fan Tianlei hadn't come over, Jiang Yanhai really wouldn't remember this. He just remembered doing research recently, and Li Ruobai was also doing research, and she never told Jiang Yanhai about these things.

Speaking of this, Jiang Yanhai thought about it, and it seems that Valentine's Day has never happened before.

Looking at this model aircraft, it was obviously not given to him by Fan Tianlei.

It was given to him as a gift.

This... He didn't know whether to say the chief of staff was good or bad.

After thinking about it, I still can't return this thing, even if I don't give it to girls, it's not bad to keep it in the dormitory by myself.

However, there are less than 7 hours left until the end of the 150-hour long-term start-up test.

This matter is obviously the current top priority. So far, Jiang Yanhai has not received a call from Professor Zhao and the others. At this time, no news is the best news!

While studying, Jiang Yanhai quietly waited for the last 7 hours to pass.

When the sound of Erdan sounded in his mind, he did not receive a call from Professor Zhao, but Jiang Yanhai was not in a hurry, because this thing has a detailed inspection process, even after the final test is over, it is estimated that he will receive It will take at least four or five hours to get results.

Sure enough, Jiang Yanhai received a call from Professor Zhao until after 9 o'clock in the evening, which is the fifth hour after the end of the 150-hour long test drive.

"Xiao Jiang!"

"It's me, Professor Zhao, what's the result?" Jiang Yanhai asked immediately.

"The results are great! At present, the long test run of up to 150 hours has ended without any problems with the airframe. The structural problems, especially the current performance of the wearing parts and load-bearing parts, have hardly been affected by much. Running Impact!"

"This result is very amazing! Although the long-term continuous test on the ground cannot completely match the real air combat environment, this test result has surpassed all the known engine test results."

"If the structural strength of its other components can keep up, then the life of this engine can reach at least 6,000 hours to 8,000 hours according to my estimation! Can it surpass the life of F119 for more than 8,000 hours, I dare not Guaranteed, but this is the first case in our country!"

When he said this, Professor Zhao's tone was obviously very excited, because he knew very well what it meant. It meant that China was finally no longer ridiculed by the West in the field of engines!

And left them far behind!

"Well! Great! Professor Zhao, you should pay attention to rest. Next, I am afraid that I will trouble you to start the long-term test of the overall test. I am afraid it will take at least 3,000 hours." Jiang Yanhai said seriously.

"Don't worry, this matter is left to us, and we are also ready to start the destructive test drive at the same time." Professor Zhao said simply.

"No problem, the big deal is to produce a few more units. If the test workshop is not enough, you can find other research institutes with similar capabilities to conduct different levels of test runs at the same time." Jiang Yanhai added.

"Well, our research institute doesn't have a high-altitude test platform. This may be done with Taihang. You need to contact this." Professor Zhao added.

"I understand." Jiang Yanhai nodded and agreed directly.

The high-altitude test bench is to simulate the environmental conditions of the altitude and speed of the aircraft flying at high altitude on the ground. It is also necessary to simulate the stable flight state of the aircraft and the flow state of various distorted airflow at the entrance of the fighter engine in the air.

Different flow velocity, different temperature airflow and static engine form relative motion, simulating high-altitude environment or high-altitude high-speed rush to the war zone; or low-altitude and high-speed flight through the enemy's air defense position; or waiting for Mach number to climb to occupy the commanding heights of aerial combat...

Different "pressure distortion" air intake devices, through system equipment, artificially establish various working environments of the engine in the air within the full flight envelope, assess and identify the design indicators and combat technical performance of the engine, etc.

There are very few such difficult high-altitude test rigs in China, and these are only available in the National Research Institute.

Jiang Yanhai and the others have already come up with this engine, and they must go to this test bench for various tests, and these Professor Zhao obviously have no way to contact them, only Jiang Yanhai himself.
