The engine idle for more than a minute, and the commander-in-chief ordered acceleration when he saw that Peng Huading had no opinion.

As his order was given, the rumbling sound of the engine sounded, and although Peng Huading and the others sat in the monitoring room, they still felt the shaking of the earth and the dullness of the sound.

Not only the footage transmitted through the guò camera, but also the actual situation seen through the bulletproof glass, the high-speed rotation of the engine completely fell into the eyes of these experts. I saw an orange-red flame erupting from the vent at the rear of the engine, and then slowly turning blue.

Peng Huading glanced at the number of rotational speeds and saw that the display screen showed that the rotational speed was 65 percent, 68 percent, and 70 percent of the rated speed......

As the speed continues to increase, the thrust value of the engine also increases rapidly, and when the speed reaches eighty, the thrust value displayed on the display has exceeded 1200 N!

Several experts standing behind Peng Huading looked at each other, you look at me and I look at you, and their eyes are full of suspicion: Is this number jù real? This is more than the maximum value of the American F119 engine, let alone compared with the Taihang engine in our own country.

You must know that the speed of the engine is only 80% at this time. If it reaches 100 percent, what a staggering number.

In fact, this number is already in the information in the hands of the experts, but these materials are information, and the experts do not believe it at all, even if the facts are in front of them, they still have doubts.

At this time, the engine is further refueled, and the speed is increased even further: 85 percent, 88 percent, 91 percent......

And the thrust is increasing accordingly: 125 Ox, 131 Ox, 135 years!

When the engine speed reaches 100 percent of the rated speed, the thrust of the engine reaches 154 kN!

The engine ran at this speed for a full twenty minutes. And the thrust of the engine was maintained at the value of one hundred and fifty-four kN.

Several experts were pleasantly surprised, and they finally accepted this reality: the engine manufactured by Peng Huading was indeed a cow, which changed the backward appearance of China's engine in one fell swoop.

After running steadily for twenty minutes, Peng Huading personally came down to let the engine go into overdrive. As the volume of fuel is delivered, the roar of the engine is louder, and the corresponding blower revs faster, blowing more air into the engine intake to more simulate the speed of an aircraft in the air.

The engine speed increases on the display: 105 percent, 110 percent, 115 percent......

And the thrust of the engine also increased: 16,000 N, 168,000 N, 175 N......

It wasn't until the engine revved at more than 30 percent that all the experts began to turn pale and were worried about whether there would be a problem with the engine. Peng Huading stopped increasing the input of aviation kerosene. The thrust of the engine is also stable at the value of two hundred and eight thousand N.

Peng Huading listened carefully to the sound of the engine, and after listening for a long time, he didn't hear a single noise, so he nodded and said, "Not bad!" Our trial was a success! ”

"Success?" Deng Guohong, who was next to him, asked in surprise. The others also looked at Peng Huading in puzzlement.

Deng Guohong: They are not questioning Peng Huading's voice. Nor is it that the number of engines is fake. Rather, because according to the syllabus of the test. The engine must run steadily for more than three hours. Now it has been slowly increasing the speed, and only when the rated speed is 100% stable for 20 minutes, how can it be said that it has succeeded? In the unlikely event that the turbofan blade disc of the engine runs for an hour and becomes deformed due to high temperatures. If the performance deteriorates due to high temperatures, the test is a failure rather than a success, and it only provides experience for future improvements.

The reason why two units were brought in this test run was not to verify their similarity, but to prevent one from breaking down in the case of high temperatures and the other from being connected to continue the test. The purpose is to save Peng Huading's time, his time is too precious, he can't let him stay here for a few days and nights because of an engine test, and there are many new equipment and new products that need his guidance.

The deterioration of aero engine performance in high temperature is a common phenomenon of China's engine, which not only restricts the operation of the engine at more than the rated speed, but also greatly shortens the service life of the engine.

They didn't know that Peng Huading had rich mechanical and electrical knowledge and experience, and they could know that the engine was running at ultra-high speed by the noise they heard, and that they had overcome the obstacles of high temperature and could run in this harsh environment for a long time.

Peng Huading smiled and said to the people around him: "It's okay! This engine can work at 130 percent of the rated speed for a long time. In fact, this rated speed is your design number, which is calculated by you according to the technical principles of American and Russian aircraft engines, and you have not taken into account our improvements, if you consider the characteristics of our design, and then calculate, its rated speed should be the current speed, that is, 130% of the original rated speed. ”

"Ah-" An expert immediately grasped the meaning of Peng Huading's words and hurriedly asked, "You mean that our engine can still increase the speed?" How much can that be improved? Can its thrust be increased? ”

Hearing his words, everyone, including Deng Guohong and several generals who were not technical experts, looked at Peng Huading with dismay. Obviously, they would prefer that the expert's question would be answered in the affirmative by Peng Huading.

Peng Huading was happy and said with a smile: "You, you, you have detained the words in my words so quickly, fortunately, the country will not let you go, otherwise you must be a good lawyer if you want to be a lawyer." Speaking of this, he nodded, "If you set the rated speed to the current speed, then it can naturally run beyond the rated speed." ”

Peng Huading, who was about to stand up and leave here, sat down again, pointed to the number on the display screen and said: "If my ears are not mistaken, we can also increase the speed of the engine by 20 percent, and the thrust should be increased by 15 percent, to about 241 N." ”

Hearing what he said, the others were not surprised, they could only try to increase the rev by another twenty percent, to see if the thrust he said could be increased to two hundred and forty-one N.

These numbers seem inconspicuous in the eyes of ordinary people, and it seems that there is nothing to increase a little or decrease a little, but in the eyes of aviation experts, these numbers are too precious, and they know very well what it means that every 1,000 N thrust added by the engine means that it not only means that the aircraft can fly faster and higher, but also means that the safety of the aircraft is greatly increased, and the aircraft can shoot down the enemy in battle to protect itself, and the thrust of the aircraft is large, the aircraft can be made larger, can be loaded with more instruments and equipment, and can greatly improve the performance of the aircraft. It can also greatly increase the bomb load of the aircraft, increase the fuel load of the aircraft, increase the strength of striking the enemy, increase the time of the aircraft in the air, and improve the comfort of the pilot.

It can even increase the size and weight of the aircraft's frame, increasing the firmness of the aircraft.

Seeing the green light in the eyes of various experts, Peng Huading smiled again, and after drinking a cup of tea, he directly operated the control platform and increased the speed of the engine by 20 percent.

The roar of the engine was louder, and the flames from the tail spout turned pale blue and cyan.

The thrust tested was 242,000 N as Peng Huading said, which was only 1,000 N different from the figure he said.

After the sound and vibration of the engine stabilized, Peng Huading stood up and said to the commander-in-chief: "Immediately notify the oil supply department to increase fuel, let the engine run at high speed for a long time, and reduce it from this maximum speed to idle speed every three hours of operation, and then increase from idle speed to maximum speed. ”

The commander-in-chief glanced at the others, but then immediately raised his hand and saluted, "Yes!" ”

Peng Huading also instructed: "After three days and three nights of continuous operation, you can reduce the following speed of the blower by 30 percent, simulating the operation of the aircraft in an environment with thin air at high altitude." Other conditions remain unchanged, and the three-hour cycle continues for twenty-four hours. ”

The commander-in-chief asked in disbelief: "Thirty percent?" With so much dropping, can it still work? ......, should the top speed be reduced? ”

Peng Huading asked rhetorically: "Did I ask you to consider the speed of the engine just now?" ”

The commander-in-chief's face turned red, and then his feet slammed into each other, and he said loudly: "Yes! Resolutely complete the task. ”

The excitement on his face can be seen by anyone, this excitement is not criticized by Peng Huading, but he is proud to be able to test such an excellent engine with his own hands.

It can be said that although the test has not yet ended, the history of China's aero engine has been rewritten. And he is also a participant in the rewriting of history. Gone is the history of our country's admiration for American and Russian engines, and in the future, only they will look up to us.

Envy, jealousy, hate, come quickly!

Of course, the commander-in-chief is not the only one who is excited, and even the commander-in-chief is not the one who is excited. Peng Huading only left accompanied by Deng Guohong, none of the other experts and generals were willing to leave, they all looked at the engine running outside the fiberglass wall like a peerless beauty, if it wasn't for the loud sound of the engine, if it wasn't for the fact that the soldiers with loaded guns formed a blockade line, and the experts were not allowed to venture to go, they really wanted to take a closer look and see why the engine they personally participated in the design and manufacture had such good performance.
