Li Fanyu's design drawings directly plunged the R&D center into a boil. The entire design drawing, one whole plus twelve subsystem sections, covers more than 7,000 parts. This thing, not to mention one person, even if it is a whole team, regardless of whether it is feasible or not can be put into the stage of experimentation, it just works on the surface, and it can't be done at all in a year and a half!

But now, this design drawing is really switched on the screen one by one, presented in front of everyone!

All the problems of the previous team unit price list are no longer there at this moment, and the previous meeting discussion, about the recruitment plan in the fields of thermodynamics, aerodynamics, etc., and which part to start with, and which part of the plan that may encounter problems, are completely meaningless in front of this design drawing.

It feels like a legend that there is a fierce and abnormal monster from outside the village, but when you gather the villagers of the whole village and take the best big sword in the village to fight, you find out that it is a fucking husky!

Xu Fufang was speechless, he only felt that he remembered a mouthful of phlegm in his chest, and he couldn't spit it out, and he couldn't swallow it.

Wang Rui looked at the design drawings again and again, and made sure that this thing didn't look like Li Fanyu had made it out at random to fool people, and finally sighed: "Brother Fan, I think you should consider your ginseng safety issue." If this thing works, there's a good chance you'll be captured by the Eagle Nation or aliens and sliced into the structure of your brain. ”

Li Fanyu disagreed.

Slice?

Inexistent!

If I die like this, I will cut it a long time ago!

What does it mean to be alive until now?

Protagonist aura!

Is there a protagonist who has been sliced?

"I think the main problem at the moment is to get this thing ...... first Well, Tianxing I-1 is made, and it is better to go through a wave in Taijia and see if it can operate normally. ”

Xu Fufang also came back to his senses and expressed his opinion.

"By the way, senior brother, you're too scary. We are very skeptical that such a thing has been made quietly?"

"Although I don't know much about aviation development, looking at this structure, the design difficulty must be more than one level higher than all the engines under our group. My feeling is that we should make it first and see if we can see what the actual performance and reliability are. ”

There was gossip around, and even if the high-level R&D engineers of the Zhengxin R&D Center knew that Li Fanyu could not understand it in a conventional way and three views, they had no score in their hearts.

"Of course, you have to make it first!" Li Fanyu waved his hand in a gaze that obviously had a lot to say: "What are you calling here for? The main thing is to improve this design and put it into physical testing! Okay, let's do it first!"

……

With infinite skepticism, the engineers of the R&D center set off.

In fact, everyone clearly knows that in the field of aviation development, it is not manufacturing that is difficult for Zhengxin. Automobile manufacturers are a comprehensive industrial industry, and the current processing scale of Zhengxin has covered every link from materials to precision machining.

The difficulty lies in a design. But now, this most worrying link has been solved by Li Fanyu in a dreamlike way, which inevitably makes people feel unreal.

It was with this trance that the trial parts of Tianxing I-1 began to be distributed to the hands of various responsible teams for creation. With more than 7,000 parts, it is not a particularly difficult thing for Zhengxin.

In just over a week, all the parts have been manufactured, passed the index test and put together. 、

Zhengxin Tiancheng R&D Center, Power Laboratory.

A ceramic layer composed of antioxidant connecting layers TGO and ZrO2 and a small amount of stabilizing Y2O3 without any spraying, the appearance of a milky white gas turbine engine was finally presented in front of everyone.

Different from a week ago, at this time, people's expressions in the R&D center have changed from deep doubt to strong expectation!

In the past week, the teams responsible for the subsystem of the Tianxing Aviation Development Project have each carried out tests and succeeded in one step, which made everyone shocked by Li Fanyu's design, and at the same time, they were also full of confidence in this Tianxing I-1.

Compared with the automobile engine, the R&D personnel of Zhengxin did not feel it under the whole set of design given by Li Fanyu. But when it came to the test, they felt the difference between the two.

According to Li Fanyu's instructions, the first thing is to focus on the performance, reliability and maneuverability of the engine, and carry out the whole machine test, component test, reliability test, and high-altitude environment simulation operation test.

After these tests are successful, the pilot engine is handed over to the upper flight, and professional equipment is used in their test site to carry out dynamic measurements, transition state measurements, high temperature measurements, interstage parameter measurements, acceleration mission tests, maneuvering load simulators, telemetry remote control, test numerical simulation, test databases, condition monitoring and fault diagnosis, and various new sensors and other test links.

The first one was the bench feasibility test. This test, to say a thousand things and ten thousand, no matter how much you whitewash the noble, to put it bluntly, is actually just to see if the engine can operate normally.

In the test of the car engine, there are actually five steps.

But when it comes to Hangfa, it's much more cumbersome;

After the engine is installed, before the first start, you must ensure that the interfaces are connected normally, check whether the outside of the engine is clean, and whether there are oil stains, so as to identify abnormal leakage that may occur when parking and driving, right?

You have to know the preparation of the equipment of the test bench and the preparation of the work site, right? Engine power-on inspection, all the systems involving the engine electrical need to be power-on check and adjust in the shutdown state, do you?

After the inspection was completed, it took more than an hour for the R&D team.

The engine fuel system is then flushed with fuel to remove the oil left behind to open the inside of the engine. Then replace the oil seal lubrication in the lubricating oil system with working lubricating oil according to the regulations, blow clean the oxygen system and check the tightness of the oxygen system, and remove the air in the hydraulic oil system......

This set, another hour.

Li Fanyu was sleepy,

"Where did you all learn the testing program?" he yawned, Xu Fufang said behind him.

"Brother Fan, this is done in strict accordance with the international inspection process of Hangfa!" Xu Fufang obviously did a lot of homework, and talked about the whole set of test procedures.

I heard that there are seven inspection links, such as the inspection and adjustment of the engine control system, the inspection of the afterburner process, the work inspection of the lubricating oil system, and the inspection of engine tightness.

Li Fanyu's face darkened,

Fuck! If it's so troublesome every time, won't it take a day for your level 6 car to start?

"Let's pull it all, those jobs will be added later, turn on the engine first, and start the test run directly after cold running!"

Li Fanyu slapped the board.

At this moment, Dai Meng, the help of Xu Fufang, walked to the two of them, leaned over and said: "Chairman Li, Mr. Xu, someone from Shangfei is here, saying that he is here to send R&D materials and talk about the basic direction of Hangfa R&D." ”

"Oh?" Xu Fufang raised his head: "Which one is flying?"

"Their chief engineer Huang Haixing, and ......" Dimon looked at Li Fanyu and whispered: "There are also Mei Yishu and others." ”

"Ha!" Looking at the Tianxing I-1 in front of him, who had already begun to empty the lubricating oil, Li Fan smiled unkindly.

"These bigwigs personally sent us materials, are they using us as elementary school students? It's better to come early than to come by chance, since you are here, let's take a look at our test car together!"
