Test run in afterburner state!

The engine entered the maximum working state, the sound of the engine working was obviously louder, and on the huge air intake grid, a small red ribbon fluttered in the wind, which represented that a large amount of air was sucked in from the outside.

Before the commission, the staff of the second workshop carried out a thorough hygiene, and in front of the air intake grid, the ground was clean and spotless, and if there was dust and sand particles, it must have been sucked in.

On the test bench, the light blue flame erupted from the tail of the engine was significantly lengthened, spewing out a strong air flow, generating a huge thrust of more than 50,000 pounds, and the strong air flow was ejected from the huge tail grid of the test plant.

Above the exhaust grille, a small red ribbon was blown with a rattle. In the test control room, many people looked at this qiē through the huge glass observation window, especially when they saw the afterburner state test drive, the movement became significantly larger, and many people's hearts were invisibly raised.

Afterburner working condition, this is the real test of the engine!

In the entire test control room, no one spoke, either looking at the LCD screen on the test control platform or looking at the engine on the test bench entering the maximum working state through the glass.

In the whole test control room, there is only the sound of the engine working, which may be because the sound insulation effect of the glass is better, or it may be because the engine is fully considered for noise in the design, even if the engine enters the afterburner working state, the sound is not unbearable.

Li Tianfeng couldn't help but nodded, comfort, as the power of a civil airliner, this point must be considered, comfort includes engine noise, vibration and other parameters.

Time passed second by second, and the afterburner state was 120 seconds, but it was just two minutes. It seemed like 20 minutes had passed, until the time came, and the test driver slowly pulled down the throttle lever, pressed the stop button, and the engine gradually stopped. Everyone came to their senses.

If nothing else, the test was a great success. Sure enough, after the engine gradually stopped, and finally stopped completely, the loud reports of several test drivers spread throughout the test control room.

"Fuel consumption is normal!"

"The noise is normal!"

"The vibration is normal!"

"Engine back-spin is normal!"

"The number of items is normal!"

“……”

With a normal sound, the entire test control room became a sea of joy, everyone first applauded, and when the applause stopped, many people cheered. Some of them even jumped!

"Wow! The first test run was a success!

"I'm so happy we succeeded!"

"Success, success!"

Li Tianfeng glanced around, saw that the whole test was full of joy, and couldn't help but smile happily, the first test was completely successful, and it was definitely something worth celebrating.

Li Tianfeng shouted happily: "Director Xiao, hurry." Celebrate with a cannon salute! ”

Xiao Guoqiang immediately changed his role, and changed from the test commander just now to the salute firefighter in an instant. Rushing out of the test control room, just a few minutes later, a burst of earth-shattering salutes came.

At the gate of the factory of the test engineering center, dozens of barrels of ceremonial flowers had already been placed, and more than a dozen employees had long been on standby, and Xiao Guoqiang ran over. As soon as he shouted loudly, the dozen or so employees immediately ignited the fire, and the salute rang out to the sky!

The employees of the entire test engineering center have been paying attention to the test run of the first turbofan engine and hearing the earth-shattering salute. I came back to my senses right away.

"Haha, our turbofan engine was successfully tested for the first time!"

"This salute, how festive it sounds, how refreshing!"

"It worked, we made it!"

The majority of employees, everyone is almost running to tell each other, this festive news soon spread throughout the test engineering center, such good news, as if growing wings, did not take long to spread throughout the entire Tianfeng Technology Company, almost all employees have learned the good news!

"Lao Wang, our first test drive was successful!"

"Yes, it was successful, I can't imagine that the one-time test was successful!"

"I'm so happy, no, I'm going to tell everyone in our office the good news."

“……”

The success of the first test run, such a good news, not only spread throughout Tianfeng Technology Company, but also to the E factory, which is also an aviation industry enterprise.

"Tianfeng Technology Company is really amazing, the first test run was a one-time success!"

"Yes, I heard that the test run was very smooth, it's really amazing!"

"It was a first-time success, how good the quality of this engine must be!"

“……”

Zhu Maohua, Yang Xianfeng and other high-level executives of E Factory naturally heard such news, and when they heard the news, Yang Xianfeng picked up the phone as soon as possible and called Li Tianfeng to congratulate him, while Zhu Maohua had mixed feelings in his heart.

Zhu Maohua muttered: "Tianfeng Technology Company is amazing! ”

Thinking of the original test scene of his turboshaft C engine, he tested it many times, changed it repeatedly, debugged it repeatedly, and finally barely got through, Zhu Maohua knew that the gap between Factory E and Tianfeng Technology Company was getting bigger and bigger.

Thinking of Tianfeng Technology Company's success in winning more than 40 billion orders at the last air show, and thinking about the output value of Factory E of only more than 300 million yuan a year, Zhu Maohua has to admire Tianfeng Technology Company while having mixed feelings.

Good things don't go out, this is not absolute, Tianfeng Technology Company completed the first test run perfectly, such a good thing not only spread to Factory E, but also to Zhang Haiping.

Zhang Haiping made a phone call, and his tone was very happy, "Mr. Li, congratulations on completing the first test run, hearing such good news is enough to make me happy for several days." ”

Li Tianfeng smiled and said, "Director Zhang, you are quite well-informed, I was about to call you, and you called." ”

Zhang Haiping laughed and said: "Mr. Li, you are making good progress, the first test run has been completed, and the matter of applying for design finalization should also be prepared." ”

Li Tianfeng said: "We are preparing, and it is estimated that the application materials will be submitted within half a month. ”

The national project must have a large amount of scientific research funds, and the design is finalized. It is also completely justified, and it is more convenient that this turbofan engine will have an official code name, such as turbofan XX, this specific code name, which will eventually be determined by the relevant competent authorities.

Zhang Haiping said with concern: "Mr. Li." Hurry up the design and stereotype, and I will try to help you if I can. ”

Li Tianfeng said: "Director Zhang, thank you so much!" ”

The two chatted for a long time on the phone, and at the same time, Zhang Haiping also informed Li Tianfeng that the modification of the Yun-8 aircraft to the turbofan engine of Tianfeng Technology Company had been started, and the Yun-8 aircraft factory had received the task and was preparing the technical plan.

What the military means is that one Y-8 aircraft is converted from four turboprop engines to two "TFWS001" turbofan engines produced by Tianfeng Technology Company. Each engine has a thrust of 50,000 pounds, and two engines will provide more than 100,000 pounds of thrust.

In this way, the power of the Y-8 aircraft will be very strong, the transportation capacity will be enhanced, especially the range will also increase by more than 30 percent, or even more than 50 percent.

According to the new plan, the improved H-6 will be equipped with two "TFWS002" turbofan engines. The total thrust is more than 40,000 pounds.

The H-6 is currently powered by two turbojet engines, each with a thrust of 93 kN (basically equivalent to 20,000 pounds). Modified "TFWS002" turbofan engine, although the total thrust increased slightly, but one is a turbojet engine, the other is a turbofan engine, and the fuel consumption of the two is not the same.

After modifying the "TFWS002" turbofan engine, the new H-6 will increase its range by more than 50 percent. This is one of the main reasons why the military is interested in the "TFWS002" turbofan engine.

Ending the call with Zhang Haiping, Li Tianfeng couldn't help but have the image of the H-6 in his mind, and after thinking about it, he said in his heart that he would modify the "TFWS002" turbofan engine. Perhaps, this is the lowest-cost, fastest and most adaptable scheme at the moment.

However, to be honest, Li Tianfeng is not optimistic about the H-6, this military's active main bomber, compared with the active bombers of the United States, Russia and other countries, is too old.

In fact, the strength of China's aviation industry determines that most of the military's aircraft models are relatively old, and there is a huge gap between them and the United States, Russia, and other countries.

Fortunately, the military adheres to the principle of good steel on the blade, focusing on the research and development of fighters, with the full service of the J-10 fighter, coupled with the introduction and imitation of the Su-30, the test flight of the J-20, etc., and the gap between the United States and Russia and other countries in the fighter plane, unlike bombers, transport planes.

The full service of the improved Wuzhi-10 has greatly shortened the gap with the United States, Russia, and other countries in terms of armed helicopters, and with the successful development of the military's new military medium-sized transport helicopters, the gap in transport aircraft and helicopters has been shortened considerably.

This may be something to be happy about, but Li Tianfeng really can't be happy in his heart, thinking about the backward old transport planes, bombers, etc., Li Tianfeng's heart is relatively heavy, and he knows that there is a long way to go.

In Li Tianfeng's mind, a variety of advanced fighters, advanced military transport planes, bombers, etc., came to mind, this is the memory of later generations, technology is decades ahead of this era, if these things can be successfully developed in their own hands, how accomplished it will be.

However, the road can only be taken step by step, first lay a good foundation, do a good job of aero engines, and only after having a certain strength can the development of these aircraft be launched.

Perhaps, this is a matter of a few years later, Li Tianfeng also considered giving these things to the country, but considering the current strength of the domestic aviation industry, it is better to develop it yourself, perhaps, after several years of hard work, an advanced aircraft can be developed and manufactured.

There is still a long way to go!

Li Tianfeng couldn't help but think, the road is still very long, and he still has to work hard step by step.
