"Very good, all units carefully monitor the data and report it at any time."

Before the words were even completely spoken, Master Wen increased the engine on the bench to the maximum thrust, without even making too many transitions in the middle, and directly and savagely pushed the rod to give oil. A puff of black smoke from the engine could be clearly seen, but that was only a matter of seconds.

Needless to say, the cause of this black smoke knows how it came about, and there is no need to even analyze it, everyone continues to stare at the data tested by the measurement and control console, and the two numbers of red and green look a little different in the indoor environment.

"The engine conversion speed is 103.5%, which is about to reach the spindle speed threshold."

"The engine vibration data is good, and there is no trend of resonance of the whole machine."

"The temperature of the high-temperature turbine blades is 1410 degrees Celsius, which is about to approach the over-temperature warning line and is about to reach the high-temperature warning line!"

Although these data can also be seen through the general control console display in front of Mr. Wen, those nervous and exciting reports and warnings are irreplaceable, and it can add tension to the already tense atmosphere of the entire measurement and control center.

Even Yang Hui, who watched the engine test in the safety zone far away, could feel the tension and excitement of the scene, this time was indeed a critical moment of life and death, and the ultimate performance of an engine was probably tested at this time, if the limit threshold could be effectively broken again, it meant that the thrust margin of the engine was sufficient. This will be of great benefit in subsequent engine testing and improvement.

And with the sound of reports one after another, Chief Master Wen turned a deaf ear. This level of data alone is not enough, and it is clear that the limit threshold of this engine is not yet reached. There can be more surprises if you squeeze it a little more, that's still for sure.

At this moment, the chief engineer had nothing in his heart, and steadily continued to increase the thrust of the engine, and saw that the thrust data increased again from 7866KG, starting from single digits: 6.7.8.9.0.1

"The rotational speed is 105.1%, exceeding the limit threshold, exceeding the limit threshold!"

The high-pitched and impatient report suddenly sounded, and the entire measurement and control hall became quieter. Seeing that the measurement and control data exceeded the limit threshold of 105%, the measurement and control personnel did not press the stop button. The only thing he can do is to report the measurement and control data at any time, so that Mr. Wen can always understand the operation status of the engine.

The scarlet warning light kept flashing, and even the eyes of people who were shaking were uncomfortable, but at this time, Master Wen had no intention of lowering the thrust, looking at the various data displayed on the main console now, almost all of the data exceeded 100% of the maximum conventional data, and it was time to prepare for a new action.

"The total temperature data of the high-temperature turbine is reported, and all three test points are reported."

I finally heard the chief engineer speak. This is to ask about the data of the total temperature of the turbine, and the young measurement and control guy immediately reported the technical data calmly and clearly.

"The temperature of the leading edge of the leaf is 1416 degrees Celsius, the posterior edge is 1406 degrees Celsius, and the root of the leaf is 1420 degrees Celsius."

Roughly understanding the working conditions of the high-temperature turbine, Mr. Wen also clearly remembers that the maximum danger threshold of this type of turbine blade is 1425 degrees Celsius, and the turbine blade will directly change the metal structure after exceeding this threshold. This change is absolutely irreversible, and as soon as there is a change, the turbine blades are ready to fly.

With 5 degrees Celsius still to go to the limit threshold, how much thrust can be squeezed out of such a small margin? Master Wen didn't know about this question, and there was no need to know it. With the current test data, it is considered a success, and there is no need to continue to take risks.

"Take note of the data this time. THE ENGINE HAS A MAXIMUM TEST THRUST OF 7882KG AND A MAXIMUM SAFE THRUST OF 7756KG. Max"

Although the engine has not been stopped, but it is better not to continue to increase the thrust, the measurement and control group, the designer system, and the engineer system are sweating in their hearts just now, in fact, the thrust of the CG-2000 engine has already met the power requirements of the MPC-75, but who can know that Mr. Wen is so fierce, directly overloaded the engine, fortunately there is no problem now.

The technician in charge of the test is also busy writing down the data, although there will be real-time data printed out in real time through the printer in the end, but Mr. Wen still likes the feeling of recording data in real time, and he feels that it is more reliable and safer.

Suddenly, the original scarlet light of the TT&C center suddenly dimmed, and the green light once again took the upper hand.

With the final stop of the engine, the test was stopped, but this does not mean that the test is completed, and the subsequent engine damage assessment and data analysis work are also very important, the test is only to get data, it is for data analysis, and this data analysis will take a few days.

When Master Wen walked into the crowd again, his face was still flushed with red light and beads of sweat, this was because the high-temperature gas emitted by the engine in the test dried up the air nearby, can this person not be hot?

"Yes, the engine thrust has reached the expected target, which is much higher than the 7400KG thrust required by Xifei, I believe this is a very exciting good news, what do you think?"

In the end, it obviously became a question about the MPC-75 power system office that came from Xifei, but it didn't matter, what Chief Wen asked was also what everyone present was concerned about, and he listened to Xifei's attitude with all kinds of ears.

"Very good, although I didn't see the final data analysis, but the maximum safety thrust of 7756KG has exceeded the data we require, just by virtue of this CG-2000 engine surpassed the CF-34-3 engine, according to the latest news from GM, the thrust of their engine is just over 7400KG, not even 7500KG, that is to say, when the engine is increased in the future, the aircraft increases the range, the number of passengers and other improvements, The CG-2000 engine will have an even greater advantage. ”

The engine to increase the thrust is a plan that Southwest Science and Industry has long had, but obviously not now, as for what level can be reached after increasing thrust in the future, it is really hard to say, as long as Yang Hui is willing to believe that this engine can even achieve a maximum thrust of ten tons, and it all depends on whether the MPC-75 can be changed more and more.

After another polite and discussed, all the important nodes of the CG-2000 engine have almost passed before the finalization, and the follow-up is to continue to carry out various tests, extreme weather tests, extreme take-off and landing, extreme and other tests, in order to be able to enter the international market in the future, and even need to be tested in accordance with the European Civil Aviation Authority's requirements for aero engine trials.

Now the CG-2000 engine should not think about anything to enter the American market, after all, it is still the largest nest of General Motors, CG-2000 is still honestly get the airworthiness certificate of the Civil Aviation Administration of the Republic and the European Civil Aviation Agency, and then talk about others.

"Mr. Yang, you also see that we are still short of manpower, although you promised the 420 factory technicians to supplement, but later the 420 factory technicians are less than half of us to do turbofan 12 engine technicians, so we now want technicians, more technicians, really can't give us to supplement fresh college students, now it's early May, you can go to universities around the country to start recruiting."

At this time, Yang Hui was still very embarrassed, he didn't expect that there was an FT-8 gas turbine project in the 420 factory, and the FT-8 gas turbine project happened to be a gas turbine improved from the JT8D turbofan engine, and the JT8D gas turbine was equivalent to the turbofan 8 engine in the 420 factory.

The 420 factory wants to pull the original turbofan 8 engine technicians to engage in gas turbines, which is a big project related to the job bowl of the 420 factory in the future, and half of the technical personnel can be divided into the CG-2000 project, which is already the 420 factory in the jumping sale, Yang Hui and Director Bai are not good to force more, which leads to the current CG-2000 engine project team There is still a lot of shortage of technical personnel.

"Yes, but this kind of thing should be run by the new United Aero Engine Company itself, and the head office will give the indicators on the line, and it is now the beginning of May, and the people can be set in June, so let's do it as soon as possible." The imperial capital, Jinling, and Chang'an can all be visited. ”

Wait, "Imperial Capital" "Early June"

How can I forget this, this really shouldn't be.

"Remember, you can recruit college students, but it must be completed before the end of this month, and after recruiting people, pull back to the unit immediately, don't let them stay too much, never more than the beginning of June, you must remember, the number of people should also try to recruit more, and the company will give more indicators."

At this time, Yang Hui will not be stingy anymore, it is at the juncture of this major event in the imperial capital, Yang Hui cannot prevent that incident from happening, he does not have the ability, the only thing he can do is to recruit more college students now, and save some if he can save some.

If you don't make a move now, it will be difficult to recruit suitable graduates for at least three years in the future, and among those students who participated in that big event, the Republic will order that it cannot be reused and cannot be used, and Yang Hui must have the foresight to catch out the good technical talents, so as not to cry too late in the future.
