Seeing such a wonderful and beautiful action, everyone applauded happily, because most people had not read the test flight outline and did not know that this action was not among the test flight actions.

Levisman reversed!

Of course, Li Tianfeng could see what kind of action this was at first glance, and while cheering for the two test pilots in his heart, Li Tianfeng was slightly puzzled, and quickly understood what was going on in his heart, so Li Tianfeng couldn't help but smile happily.

"It's really cute, to complete such an action, eighty percent of them get carried away." After Li Tianfeng watched the series of actions of the helicopter, that is, the reversal of Levisman, Li Tianfeng guessed in his heart.

The so-called Levesman reversal is a helicopter maneuver, which is a large elevation angle to climb to a certain height and then the nose changes from up to down, and then dives back at the opposite angle, this action is internationally known for its thrilling thrills.

Of course, this is also a difficult tactical maneuver, Levisman maneuvers the guò helicopter to pull up and jump at high speed, get rid of enemy ground fire, and when it is about to reach its apex, rotate 180° around the rotor axis, turn back and immediately switch to a dive attack. This tactic is mainly to quickly carry out the transition from detachment to another attack under the enemy's ground firepower, reduce the enemy's attack time, form a huge "Mount Tai pressing the top" situation, and form a huge psychological pressure on the enemy. It is also a key tactic to increase combat effectiveness.

This kind of action is not something that ordinary helicopter pilots can play, no wonder, seeing such a wonderful action, everyone will cheer for a while, and even Li Tianfeng smiled happily.

As one of the test flight commanders and the person in charge of the test flight base, Liu Zhifang, who was wearing a colonel's uniform, changed his face slightly, and said loudly: "What is Feng Zhengqi doing, playing the piano randomly!" ”

A major next to him saw his dean angry. I couldn't help but think in my heart, Feng Zhengqi, this guy, always likes to get carried away, and now he is in trouble.

On the helicopter, Feng Zhengqi beautifully completed the Levisman reversal, and his heart was full of joy. I admired the turboshaft D engine in my heart, with such strong power and excellent performance, I just completed the Levisman reversal, which was very smooth and easy, and it was simply too enjoyable.

Xiao Zhou is the same, he sighed in his heart, it's really enjoyable, Wu Zhishi installed such an engine. It's really exciting, but Xiao Zhou is slightly worried in his heart that Lao Feng may have caused trouble if he came to such a beautiful move without authorization.

In addition to being excited, Feng Zhengqi also realized that he had an itchy technique just now, and he didn't control it. There's a Levisman reversal, and it's really possible to get into trouble.

But. Feng Zhengqi didn't regret it, he could only blame the turboshaft D engine for its excellent performance, and it was really difficult for him to control it.

It's like a racing enthusiast who suddenly has a car with excellent performance and can't help but show off his skills and have a hard time.

Pretty Levisman after the reversal. After the helicopter test flight was completed, Feng Zhengqi drove the helicopter to land slowly in the designated area, turned off the helicopter, and the rotor speed on the top of the helicopter gradually slowed down, and Feng Zhengqi and Xiao Zhou got off the plane one after another. Trot all the way over.

Standing upright in front of everyone, Feng Zhengqi saluted a military salute, and then reported loudly: "Hello leaders, the test flight has been successfully completed, and it is normal!" ”

Liu Zhifang glanced at Feng Zhengqi fiercely, the test flight was successfully completed, to be honest, Liu Zhifang was very happy and satisfied in his heart, but Feng Zhengqi came to such a Levisman reversal when the test flight was about to be completed, Liu Zhifang didn't know whether he should be happy or angry.

It's a little bit of a cry and a laugh.

Liu Zhifang still knows Feng Zhengqi well, and the two are also familiar with each other, Feng Zhengqi is not only an excellent helicopter pilot of a certain regiment of the Army Airlines, but also a test pilot of this test flight base.

Liu Zhifang said: "Feng Zhengqi, did you make a mistake again?" You're starting to get carried away again, aren't you? Do you want to clean up after you? ”

Feng Zhengqi immediately said: "Don't, don't, Dean Liu, don't, if you want to blame, you have to blame this turboshaft engine is too good, the power is too strong, and the skill is itchy for a while, so I didn't stop it." ”

Liu Zhifang couldn't cry or laugh.

Li Tianfeng smiled and asked, "Captain Feng, tell me about the test flight just now, and the more detailed the better." ”

Feng Zhengqi glanced at Li Tianfeng gratefully, obviously, Li Tianfeng was relieving himself, so Feng Zhengqi stood upright, gave Li Tianfeng a military salute, and then talked endlessly, telling the whole test flight situation, and even kept praising how excellent this engine is, how strong the performance is, and how Wu Zhishi will be if he really installs such an engine.

Seeing Feng Zhengqi's strength, he was mainly talking about how good the turboshaft D engine was, how excellent it was, and how strong the power was.

Liu Zhifang had to interrupt, "Feng Zhengqi, tell me the main thing." ”

Li Tianfeng smiled, it seems that his engine is really good, and it has actually received such a good evaluation from the test pilot.

Feng Zhengqi stood up and said loudly: "Yes, say the main thing." ”

Then, Feng Zhengqi focused on a series of situations of the test flight, which was good and detailed, of course, the uncontrollable in the middle said how excellent the turboshaft D engine was, and how strong it was, seeing this, even Li Tianfeng couldn't help but smile.

After the introduction of the test flight, as the chief designer of Wuzhishi, Mr. Wu was also happy, held Li Tianfeng's hand, and said enthusiastically: "Mr. Li, with such an advanced and excellent engine, our Wuzhishi is simply like a tiger with wings." ”

Li Tianfeng smiled happily, "Mr. Wu, then we will work together and work together to build our Wuzhi Shi into one of the most advanced armed helicopters in the world." ”

Li Tianfeng has such confidence, Li Tianfeng is not only good at the design of aero engines, but also good at the design of aircraft, and the design technology of armed helicopters is naturally not a problem.

Mr. Wu said: "Yes, work together to create the world's most advanced armed helicopter!" ”

Zhang Haiping, who was standing on the side, could be said to be the military representative of the test flight, Zhang Haiping said: "Mr. Li, Mr. Wu, you have such pride, I thank you on behalf of our military." ”

As a senior officer of the Armament Department of the General Staff Department, Zhang Haiping is well aware that the current domestic army, especially the army, urgently needs a powerful and advanced helicopter gunship.

In the world, helicopter gunships are often claimed to be the backbone of the army, and the domestic army needs to stand up its own solid and powerful backbone.

The Wuzhi 10, which was equipped with a turboshaft D engine, carried out several test flights, and completed a series of test flight subjects in accordance with the regulations, and Li Tianfeng also stayed at the test flight base for several days before finally returning to Songzhou satisfied.

In the test flight base, after staying for a few days, Li Tianfeng and Dean Liu gradually became acquainted, and Li Tianfeng became good friends with the designers of Wuzhi Shi, especially the chief designer Mr. Wu.

The two exchanged some things on technology, Li Tianfeng's many technical insights, advanced concepts made Mr. Wu's eyes shine, and even on the armed helicopter, Li Tianfeng's technical attainments had to make Mr. Wu admire.

At this time, the test flight was very smooth and perfect!

Of course, Feng Zhengqi is also the first test pilot to be punished, writing reviews and being confined to prison, the strange thing is that after being punished, Feng Zhengqi is still happy on his face.

Someone asked puzzledly, Feng Zhengqi explained, with such an excellent turboshaft engine, our Wuzhi Ten has hope, let's write a review, what is it if you are locked up for a few days.

During the confinement period, Feng Zhengqi was still reminiscing about the feeling of this test flight, as if he was still unfinished, especially in retrospect, the strong power of the engine and the excellent performance, Feng Zhengqi would be happy in the confinement room, and waved his fist excitedly.

Li Tianfeng and Qiu Wenan returned to Songzhou satisfied, and Zhang Haiping also returned to the process happily with the outfield test flight report at this time, and made a detailed report to his minister as soon as possible.

……

Tianfeng Technology Company.

On the test bench, the 2000-hour life test of this engine has been going on, working in two shifts during the day and night, in order to seize the time, Li Tianfeng did not waste time at night.

On the first day back to Tianfeng Technology, Li Tianfeng and Qiu Wen'an went to the test workshop to see the test run, and Li Tianfeng was very relieved to see that it was normal.

Because the turboshaft D engine has been designed and finalized, and the type certificate has been obtained, and the production license is being applied, it is impossible to change the design, so Tianfeng Technology Company has invested in the production and manufacturing plan of 20 engines.

As for the 10 engines that were put into production a few months ago, the manufacturing of all parts has been basically completed, and the inspection has entered the central warehouse, and the final assembly of the engines is already underway.

Although there is no production license, but it is possible to manufacture in advance, but it cannot be sold, for the turboshaft D engine, there is only one customer, that is, the military, and the turboshaft D engine produced by Tianfeng Technology Company will be sold to the military.

Tianfeng Technology is immersed in production, the company's operation is orderly, and the current Tianfeng Technology Company has a sound organization, and the company's employees are basically full, with more than 6,000 employees.

Nine manufacturing workshops, plus assembly workshops, test workshops, the largest number of front-line workers, almost nearly 4,000 people, in addition to all kinds of technical personnel, including engineering and technical personnel, designers, these personnel have nearly 2,000 people, including designers in the early 1,000s.

The rest are managers, support staff, including logistics and security personnel, which add up to just over a thousand people.

The company is booming, coupled with the imminent acquisition of the production license, Tianfeng Technology Company, since Li Tianfeng down, everyone is full of ambition and enthusiasm.
