If there is work to do, that is the best news, and Section Chief Chen, who has a keen ear, heard that there was work to do here, and explained that he came over here. Section Chief Chen looks to be in his forties, but he is in the prime of life in the aerospace industry.

"See, this is Section Chief Chen, he is responsible for the whole machine test here, and now they still have some work here, but it's not much, it's just ten days to do your little hour."

Before Section Chief Chen came over, Section Chief Li introduced Section Chief Chen first. When Section Chief Chen came over, he wanted to introduce Yang Hui again, but Yang Hui was an active person, so he didn't need to be introduced by Section Chief Li, so he was the first to talk about it.

"Hello Section Chief Chen, I'm Yang Hui, this is Comrade Zhong Jianshe from the same project team as me, we are doing micro turbojet, and I'm here to trouble you to do a test today."

Seeing this young man report to his home, Section Chief Chen stretched out his hand to shake Yang Hui's hand, and then reached out to shake hands with Zhong Jianjian.

"Hello, my name is Chen Li, and I am responsible for the engine test here."

Since the two of them have already connected here, naturally Section Chief Li won't say much, a piece of equipment over there is being overhauled, and now he is going to the scene to keep an eye on it.

"Okay, then you talk slowly, I'm going back, there's something over there."

"Okay, go over, Lao Li, there is me here, don't worry." "Thank you, Section Chief Li." This is the different answer of Yang Hui and Section Chief Chen.

Looking at the boxes that were still on the cart, Section Chief Chen walked in front to lead the way, and took Yang Hui and Zhong Jianshe to the whole machine test center. Putting the cart down, Yang Hui and Zhong Jianshe slowly lifted the box down and put it steadily, and opened the box again, revealing the parts inside.

"It's still a part, then it has to be assembled first." Seeing the vortex in the state of a bunch of parts in the box, this 40-year-old man has also seen scientific research. This should be the first time I have encountered a whole machine test with parts, and it seems that this is going to be assembled on site.

Since Section Chief Chen here is not satisfied with the vortex jet in this part state, it is easy to do. Yang Hui didn't say anything, picked up the parts and started assembly.

Fix the diffuser, deflector, bearing bearing, and combustion chamber on the inner wall of the casing. Then fix the centrifugal impeller on the bearing, pass through the bearing bearing bearing hole in the inlet direction, and finally fix the turbine at the other end of the bearing. Now the general appearance comes out, the deflector cone, the fuel line is simpler, two or three clicks.

Seeing a vortex jet assembled like this with his own eyes, Section Chief Chen felt like he was dazzled, can such a vortex turn up? This is the biggest question for Section Chief Chen now.

The final starting system, that is, an electric motor, is mounted in front of the air intake and supported by a bracket, and the motor output shaft and the main shaft of the turbojet are meshed together with the gears, and the entire turbojet is completely assembled.

"This is the vortex you designed, how many kilograms of thrust does this have?" Obviously, Section Chief Chen is not very optimistic about this turbojet, and for a test person who has been in a bunch of engine stacks with thrust calculated in tons for many years, a little guy like this is really not eye-catching.

"The plan is 8-12kg, and it depends on the test results here, but I think there is no problem."

"Okay, let's put this here first, assemble a rotor and take it over there to do the dynamic balance, and then assemble it, put the oil on it and take it here for testing."

According to Section Chief Chen, Yang Hui assembled a rotor again and took the dynamic balancing machine to the side to do correction, dynamic balancing is an indispensable test for turbine machinery, what will be the consequences if there is no dynamic balancing? Simple, it can be summed up in four words: machine destroyed, people disabled.

Dynamic balancing is to artificially make the center of gravity of the rotor and the actual axis of rotation artificially close to each other, and reduce the periodic change of centrifugal force in rotation.

Yang Hui's little vortex is a real little guy, handed over to the staff here, installed on the machine, after the test has a problem, fine-tune the imbalance, and you can do a good job of dynamic balance.

Get the rotor that is well balanced, and put the other parts on it, and this is considered a good vortex, and now it's time to test the results of the month.

"Construction, you can install the rest of the rotor and take it over there to do the dynamic balance."

instructed Zhong Jianjian, who was doing nothing on the side, to finish the remaining few rotors, and Yang Hui went to Section Chief Chen to prepare to start the test.

"This little guy is really out of place with us, it's all big guys' test equipment, and it takes a lot of effort to modify the equipment to test this little thing."

With the vortex sent by Yang Hui, Section Chief Chen personally went to the test bench, not now should it be called the test frame, in order to test Yang Hui's little guy, he can only find a way to modify the fixed point with a bracket. The small turbojet is erected on the stand, and it is well deserved to be called a test frame.

This is just a simple test run, as long as it can run smoothly, it is okay, so there is no extra equipment pipeline installed on it.

Although there is no hope for this little guy's thrust, but for this little guy, there are people who are very concerned about whether he can move, this design is too simple, if it succeeds, it can be regarded as another big event in the development of turbojet. Therefore, the people who cooperate with this test are very attentive, and it is very interesting to see this level of little guy today.

"Oops, it's still there"

"It's still not too late"

A large group of people, the entire project team except for Zhong Jianshe came together, but soon Zhong Jianshe also came over.

"Team Leader Yang, there is someone over there who is specifically doing dynamic balancing, and I will come over after assembling the rotor."

"Okay, let's take a look at the test drive here."

It seems that the people in this project team are still very concerned about this, and they all ran over as soon as they heard about the test run.

"Okay, Section Chief Chen, let's start, we're standing in this safe zone, there's no problem." Take a few people to the safe area here, and after confirming that it is safe, signal that you can start the test drive.

"What did you do, young man?"

The unfamiliar voice made the six of them all turn their heads to look at this man in his fifties, with thick glasses, and at first glance he looked like an old scientific researcher who had been engaged in design for many years, this is a figure that must be respected.

"Yes, this is a simple turbojet engine designed for a model airplane, there is nothing to look at the past data, the only highlight is that it is cheap, and today is the first test run." Xie Lianfa, who speaks quickly, is hardly comparable to his speed.

"Young people are quite capable, I have been old for so many years, and it is the first time I have seen a turbojet designed for model aircraft, which is a precedent for a generation."

This self-proclaimed Lao Wen saw at a glance the extraordinaryness of this engine, the first to eat crabs, how to go down in history, the later generations of model aircraft turbojet engines were launched in 93 years, a little-known company in France, and now Yang Hui These young men must be the pioneers.

"Where, where, this is also proposed by our team leader Yang, and the entire model aircraft project was proposed by team leader Yang."

The modest Xie Lianfa immediately lifted Yang Hui out at this time, he was embarrassed to accept such an evaluation calmly, it was too high to stand it.

"The test is ready to start, and the starter is powered on."

As Section Chief Chen issued the first order, the power supply of the small motor starter in front of the turbojet was unblocked. Then drive the turbojet spindle to rotate the impeller and start working, continuously compressing the air to the combustion chamber behind. Of course, it is impossible for a small motor to drive the spindle to reach the highest number of revolutions, so the compressed air flow cannot meet the requirements. However, fortunately, propane is used to start the ignition, so the compressed air is barely enough.

"Plug in propane and prepare for ignition."

Seeing that it was so troublesome to start a vortex spray, Section Chief Chen was helpless for a while, this little thing didn't look good, it was quite troublesome to use, where was it like those big guys in the institute, and it was started when they said it.

With the switch turned on, a weak current flowed to the spark plug, and after the current of the spark plug, an electric spark was released instantly.

It was this little spark that ignited the restless propane and air mixture in the entire combustion chamber, and began to burn violently, and the constraints of space made this hot flame only run to the deflector behind the combustion chamber, and then pass through the deflector to the turbine.

The raging flames hit the turbine one after another, and slowly, the speed of the turbine began to increase, driving the centrifugal impeller in front of it to exceed the speed of the starting motor. It was at this moment that the engine was successfully started.

Disconnect the motor from power and the turbojet continues to rotate smoothly, marking a good start.
