It took a morning to realize the design on the drawings, and when I walked out of the factory, there were already three more combustion chambers in the side bucket, and the throttle was maximized all the way. However, the speed still can't run, and the drawings in the sidecar are still not moving, how fast can this speed be. sighed in my heart: This nephew's technology is indeed a little old, after all, it is the technology of Germany in World War II, although it has the blood of BMW, but now it can be regarded as the native turtle of the Republic.

finally returned to the institute, and saw the remaining two people in the department standing at the gate from afar, the car had not stopped steadily, and the combustion chamber specimen in the collapse bucket had been taken by Tian Zhuang to observe it.

"You're pretty agile, so let's take these together." After speaking, Yang Hui went to hand over the car keys.

Section Chief Wu picked up the drawings and walked in front, this time he did not go to the office area, but walked from the fork in the side to the engine test center in the institute, where there is perfect testing equipment, for testing a miniature turbojet combustion chamber, it is simply not too simple.

Far away from the test center, I heard the shrill roar of the turbojet engine, which must be difficult to reach the miniature turbojet that is still being designed. Amid the shrill engine whistle, the three of them finally arrived at the southeast corner of the test center.

There are not so many engine tests here, there are only various test instruments, and dense wires of different colors, which are connected to the sensors at one end and the various instruments for analysis at the other end.

Due to the recent situation in the institute is not very good, the project is really a little small, and there are few machines in the entire parts test area.

The only few working machines are also attracted to these staff who have no test items, anyway, they are densely packed.

However, someone still found these two uninvited guests, and at a glance saw the combustion chamber brought by the three of them, and after careful consideration, they finally remembered that there was a project in the institute recently, but it didn't sound very good, but it was good to have something to do.

"Come here, there's a new project here." This person ascended to the top and shouted, and then those who were still watching heard it at once, and then gathered and followed.

With a hula, a group of people gathered around this side, looking carefully, of course, looking at the combustion chamber, could they still look at these three big men.

"So small? What and where is it used? ”

"I'm afraid I won't even be able to use the missiles."

"The missiles are all on solid fuel, and it's clear that it's not this."

"That's ・・・・・・"

A group of people are gossiping, no matter how they want to break their heads, they can't think of any engine with this thing, and the matter about model aircraft is only known to someone in the design center on the side, although it has been so many days, but no one is really willing to mention it for this little guy turbojet, it is too nonexistent.

Of course, some people still remembered that there is a model aircraft project of their own, which should be this thing.

"Model airplane engine combustion chamber, right. I did it at my own expense. ”

These testers who are engaged in technology and don't listen to things outside the window have finally figured it out. Then at a glance, it turned out to be like this, and now it makes sense, it's normal to be simple and small.

"That's right, this is the combustion chamber used by model airplanes, according to the requirements, what we do is very simple, just use it." Section Chief Wu didn't want to say too much, but seeing that they were all talking about this, he had to say a few more words.

"Now that this test piece has been completed, it depends on the test on your side, if there is no problem with the combustion chamber test here, we will only wait for the final installation test."

In the end, it is necessary to return to the topic: testing the combustion chamber.

"This combustion chamber is not very demanding, we have crossed out some unimportant tests, and the design life of each of the three combustion chambers is only about 25 hours. However, it should be possible to complete the test project. "Take out a test sheet and look at it, and call the person in charge here.

The person in charge of the parts test here looked at the test list of the combustion chamber and immediately had a plan, interrupting everyone's discussion and arranging the test.

"There are three combustion chambers, and this one is used to disassemble and do mechanical tests on parts." As he spoke, he picked up a combustion chamber and flipped it over for a few moments, then handed it to a person in charge of mechanical testing in the back.

Since this man received the project, he naturally happily called his subordinate testers to leave, and finally had something to do.

Seeing that some people had left, the person in charge continued to instruct, "These two combustion chambers are used for combustion performance tests."

The two combustion chambers were handed over to the two team leaders in charge of the test, and finally a group of people left with their team leaders to do the test.

The person in charge looked at the signature of the test sheet again and was a little surprised.

"Let's go, it's time to call you Section Chief Martial Arts now, right? Let's come over and fill out the test list first. ”

Section Chief Wu has also been working in the institute for ten years, and he has been working on the combustion chamber, and he doesn't know how many times he has come to the test center here, so he is naturally an old acquaintance with the person in charge.

When he was about to walk inside, Yang Hui finally found the parts test area here.

"Hey, Section Chief Wu, have you started testing here?" Without seeing the shadow of the combustion chamber, Yang Hui naturally understood that he was already starting to do the test.

"Not yet, I just sent things out here, and I'm about to fill out the test form, let's go and take a look." As he spoke, he beckoned Yang Hui to go inside together.

"Oh, by the way, let me introduce, this is Section Chief Li who is in charge of parts testing here. I've been friends for many years, and it's easy to talk to. "I introduced Section Chief Li here to Yang Hui, so naturally I have to introduce Yang Hui to Section Chief Li.

"This young man's name is Yang Hui, and he came this year, and he is the overall person in charge of the power system of the model aircraft this time."

"Hello, hello."

The two of them knew each other, so the three of them walked to the office inside, and as for Tian Zhuang and the others in the back, they had already gone to the testing area over there to watch the test.

Walked into the office, filled out the test sheets, and signed them. Then Section Chief Li beckoned to go to see the on-site test, and by the way, he had to send the test sheet, without the test sheet, there was no way to do the test below.

At this time, a group of white coats had already installed the combustion chamber and fixed it on the bench, and the sensors were installed on the combustion chamber, and some were installed on the wall of the combustion cylinder inside.

Seeing that the temperature test here has already made all the preparations, Section Chief Li took out the test sheet here and handed it to the person in charge here, and he was busy sending out the other two.

An important test here is about to start, of course, Yang Hui and Section Chief Wu will not leave, they must watch it on the spot.

"Okay, the test sheet is here, and we can start doing the tests."

Yang Hui and the two hurriedly retreated outside the quarantine area, this combustion chamber test is risky, it is better to stay away.

"Attention all units, the combustion chamber temperature test is about to begin, and unrelated personnel please retreat to the safe zone."

After seeing all aspects, they gestured to indicate that they were ready to continue the arrangement.

"The fan is ready to start, add air."

"The fan is started, it is running normally, and air is being pressed."

I saw that the fan here had already started to press air into the combustion chamber.

"Propane Gas Preparation"

"The propane is ready and ready to be injected for combustion."

"Allow the injection of propane."

The ratio of propane to air displayed on the old monitor is constantly approaching the optimal combustion ratio. Finally, when the data reached the standard, the person in charge pressed the ignition button.

With a slight bang in the combustion chamber, the combustion chamber was successfully ignited. Once successful, the ignition is still relatively reliable, and so far it has been quite smooth.

Several pairs of eyes stared at the display, the data on it was constantly refreshed, and the temperature sensor transmitted the temperature of the combustion chamber and the wall of the combustion cylinder.

Seeing that the temperature had passed the ignition point of the gasoline to 446 degrees, he decisively asked for gasoline to be injected.

"Fill in the gasoline, and the propane is ready to cut off the gas."

"Puff puff," there were a few explosions, and it was obvious that the combustion of gasoline was not stable just now, but in the end it succeeded in passing to the use of oil combustion, but the flames were still occasionally extinguished at individual intakes, but then they were ignited by flames in other places. ”

Seeing that several people here frowned, it was obvious that there was a problem with this combustion, and it should be a fuel problem.

"It's a possible fuel problem," Yang Hui said in one sentence, revealing the key problem of unstable combustion.
