"That's your solution, is it going to work?"

Looking at the obvious roughness of one end and the sharp contrast between the entire spindle, Section Chief Chen said that he couldn't believe it, and completed the technical troubleshooting in one night, re-modified the parts at noon, and came to test the car again in the afternoon, obviously surprised.

What kind of speed is this, it has been solved in less than 24 hours, and it should be sighed at the technical ability of these young people.

"Come on, old rule, assemble the engine for me."

After speaking, Section Chief Chen went to the side to convene people and immediately prepared for the test, and it was not easy to do a series of preparations for the test.

People on both sides, when Section Chief Chen was preparing, Yang Hui was also assembling the engine, this time he was really familiar with the road, and when he finally assembled the starting system, he prayed silently in his heart, although this is useless.

After assembling the engine, I took it and beckoned the project team next to me to watch the second test run again.

"Come on, let's test the car again, I believe we have found the real problem."

Seeing that the small vortex with the revised design was fixed on the test frame, everyone's hearts seemed to be tied to it, not only hanging it, but also afraid of heights.

"Attention units, the second little guy engine test begins." I don't know if I don't think that the entire test center has given this little vortex a code name "little guy". It looks like it's starting to take root.

"Roger, start the motor to power up, start and run normally."

Now is the critical moment to hear that the motor is energized, and if this time it is faster than the last time the bearing goes to full speed, then it will mean that the inference is correct. The rest of the test can basically be said to be OK.

Sure enough, the speed of this start is obviously much faster than last time, and it's hard to say how much more it is, but all kinds of test data are recorded, and you can analyze it slowly after completing the test.

"Propane to be added to the combustion chamber to prepare."

"Successful ignition start."

"Liquid fuel is being injected into combustion."

...... "Full transition to liquid fuels"

With the reported passwords, the engine continues to deepen according to the established procedures. And run smoothly, making a low hiss.

With the first experience of safe operation, Section Chief Chen did not ask other staff members to leave. Instead, he handed over the work to a deputy next to him and ran to the audience on Yang Hui's side.

"Yes, I personally feel that you have found the right cause of the problem this time."

"Then I will borrow the auspicious words of Section Chief Chen, but I don't know if there will be any problems in the future!" Yang Hui's worries are not unreasonable, the engine is like this, the environment is bad, and there are many problems.

Nodding, Section Chief Chen agreed with Yang Hui's statement, and then Yang Hui's words said, "What you said makes sense, but don't worry too much, your engine is in a special situation, one is that the thrust requirements are not high, and the other is simple and solid structure." The problem is that there are not too many, and we will cooperate with you to win the first engine independently designed by this institute. ”

Regardless of Chinese, foreigners still pay attention to a name, how this small engine still has to be crowned with a good name, independent design is the business card of this little guy. ・・・・・・

Time passed in the idle chatter between Yang Hui and Section Chief Chen, and suddenly the low hissing sound gradually became smaller, Yang Hui and Section Chief Chen stopped talking, and when they looked at the time, it turned out that forty minutes had arrived, and the test had stopped.

"Let's go, everyone go up with me to see, this time to see if there are any problems, if you have a sensitive nose, you can smell it first." Section Chief Chen called a small group of people from the design team here and walked to the test bench together.

Due to the problem of cooling, it is not possible to disassemble the parts immediately, so it is also a good way to let the sense of smell be sensitive to smell whether there is any burnt rubber.

At this time, a nearby tester had already leaned his nose up and sniffed, felt that there was no smell, and immediately reported the good news.

"There is no taste, there is no smell here for the section chief, the problem should have been successfully solved."

Hearing this exciting news, Long Derong, who was behind Yang Hui, immediately ran to the side of the test bench, approached the little guy who was still exuding heat, and sniffed carefully. Didn't smell bad. As soon as I was happy, my nose was a little close, and now it was fine, and I raised my head immediately when it was hot, and the sluggish nerves transmitted the pain to the brain, and Long Derong, who was in pain, screamed.

For a moment, the entire test center was an echo of screams and screams, and everyone laughed when they saw this, which was really lucky, typical joy and sorrow. Fortunately, the burn is not serious, and it will be fine after a while, but it will be a painful experience for Long Derong to wash his face within a week.

As a lesson from the previous car, Yang Hui waited until the engine cooled down and put on a heat-insulating glove before starting to disassemble the engine. The first thing you see when you take the starting system apart is that the entire rubber connection is intact, which is good news.

To the group of people around him, he pointed to the starting system and said, "See, there is no problem, we have successfully eliminated the fault within a day." ”

"Really, you young people have two brushes, not bad"

"Yes, that's good"

These are compliments from the testers next to them.

Put down the tools in your hand, there is no need to disassemble the engine yourself, and now you have to discuss with Section Chief Chen how to carry out the follow-up test work.

"Come, construction, you take this apart and check it, and I'll discuss the later test work."

After explaining the rest of the work, Yang Hui and Section Chief Chen came to the small office on the side. Section Chief Chen's office has no superfluous furnishings, everything is stored in the drawers, and there is nothing superfluous on the table, except for the water glass, which is completely empty.

"Sit down and talk slowly. It's going to take a while to discuss the test sequence, and you haven't been able to stand up to it just now? Seeing that Yang Hui was still standing on the side, Section Chief Chen, who was looking for something, smiled and asked Hui to sit down.

"Come, this is the test results of the parts that Lao Li gave me yesterday, I read it, many test results are okay, we can speed up the test here, and we will be exempted from some unnecessary tests."

took out a notebook, and Section Chief Chen wrote down the items that he thought still needed to be tested and handed them to Yang Hui to read.

I also did it in the test flight institute back then, and I still know and understand some test items. Looking at the test items listed throughout, they are indeed all indispensable items, but Yang Hui still found that something was missing.

Pick up a pen and write: the average time from start to successful propane ignition, from propane preheating to the time it takes to use liquid fuel, and the maintenance interval of engine deposits. These three points are unique to this unique little guy, and the engine cannot be started without these empirical data. For example, there is no specific time standard for simple propane preheating, and if the liquid fuel is introduced too early, the temperature is not enough, and the fuel cannot evaporate into the combustion chamber, and the transition to liquid fuel is impossible. So these tests are still necessary.

As soon as he saw what Yang Hui wrote, combined with the analysis of the characteristics of the little guy, Section Chief Chen immediately reacted to the significance of these tests, and immediately assured.

"No problem, we can do these tests, don't worry about leaving it to us."

I looked at the list of test items listed again, and after roughly calculating in my mind, I made an arrangement.

"There are not many projects, I arranged to do it as soon as possible, and all the parts here were assembled, there were about seven or eight engines, and if the progress was fast, there were no major problems, and I would be able to produce results in a week."

These speeds are absolutely unprecedented in engine development and testing, but this time it is necessary to create two speeds.

"That's good, the test of eight engines together must come quickly, anyway, the cost of this engine is very low."

Not only is the cost low, it can be said that the cost is low, the work is rough, the only thing that has a little technical content is that the spindle material and processing to some technology. But when the time comes, it's hehe・・・・・0.0

"Okay, that's all, I'll arrange for a large-scale test to start tomorrow, and the whole test center can remember the familiar melody again." At this time, look at Director Chen, how is it a bit like the villain Doctor Evil in the movie, and it is really obsessive to be able to describe the harsh sound of the vortex with melody.
