Seeing such a wonderful and beautiful action, everyone cheered happily, because most people had never seen the test flight outline and did not know that this action was not among the test flight action.

Levithman reverses!

Of course, Li Tianfeng could see what this was at first sight. While cheering for the two test pilots, Li Tianfeng was slightly confused and quickly understood what was going on in his heart. So Li Tianfeng couldn't help but smiled happily.

"It's so cute. If you actually complete such an action, you will probably be proud of yourself." After watching the helicopter series of actions, Li Tianfeng was reversed, and Li Tianfeng guessed in his heart.

The so-called Levithmann reversal is a helicopter action. After climbing to a certain height at a large elevation angle, the nose changes from upward to downward, and then dives back at opposite angles. This action is known internationally for its thrilling and stimulation.

Of course, this is also a difficult tactical action. Levithmann's action is pulled up and jumped through a helicopter at a high speed to get rid of the enemy's ground fire. When it is about to reach, it rotates 180° around the rotor axis, then immediately turns into a dive attack. This tactic is mainly to quickly implement the resurgence from disengagement to attack again under the enemy's ground fire, reducing the enemy's attack time, forming a huge "Taishan Pressing Top" situation, and forming huge psychological pressure on the enemy. This is also the key tactic to improve combat effectiveness.

Such movements are not something that ordinary helicopter pilots can play. No wonder, when everyone applauds when seeing such wonderful movements, even Li Tianfeng smiled happily.

As one of the test flight commanders and the person in charge of the test flight base, Liu Zhifang, wearing the colonel's military uniform, changed his face slightly and said loudly: "What are Feng Zhengqi doing? Playing the piano randomly!"

A major next to him saw his dean getting angry. He couldn't help but think to himself, Feng Zhengqi always likes to be proud and get into trouble now.

On the helicopter, Feng Zhengqi beautifully completed the Levithman reversal, and felt very happy. He admired the Turboshaft D engine in his heart. It had such strong power and excellent performance. He just completed the Levithman reversal, which was very smooth and easy, and was simply addicted to it.

Xiao Zhou was the same, and he felt that it was really satisfying. Wu Zhishi installed such an engine. It was really exciting. However, Xiao Zhou was slightly worried that Lao Feng might have caused trouble if he did such a beautiful move without permission.

While excited, Feng Zhengqi also realized that his skills were itchy just now and he couldn't control it. A Levisman turned around and he could really get into trouble.

However, Feng Zhengqi did not regret it. If you want to blame, you can only blame the turboshaft D engine for being too excellent, and it is really difficult for him to control it.

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

After the beautiful Levithmann reversed, the helicopter test flight was completed. Feng Zhengqi drove the helicopter to slowly land in the designated area, shutting down the helicopter. The rotor speed on the top of the helicopter gradually slowed down. Feng Zhengqi and Xiao Zhou got off the plane one after another and trotted all the way.

Standing attentive in front of everyone, Feng Zhengqi saluted a military salute and then reported loudly: "Hello, the test flight is completed successfully, everything is normal!"

Liu Zhifang looked at Feng Zhengqi fiercely, and the test flight was completed successfully. To be honest, Liu Zhifang was very happy and very satisfied. However, when Feng Zhengqi was about to complete the test flight, he came with such a Levithmann reversed. Liu Zhifang didn't know whether he should be happy or angry.

It's really a little funny.

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

Liu Zhifang said: "Feng Zhengqi, have you been wrong again? Are you starting to be proud again? Are you going to be careful? Do you have to deal with you?"

Feng Zhengqi immediately said, "No, no, President Liu, don't, if you want to blame, you must blame the turboshaft engine for being too excellent, too powerful, and the skills were itchy for a while, so I didn't stop it."

Liu Zhifang was amused and crying.

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

Feng Zhengqi looked at Li Tianfeng with gratitude. It was obvious that Li Tianfeng was helping him. So Feng Zhengqi stood at attention, saluted Li Tianfeng, and then talked endlessly, saying the entire test flight situation, and even kept praising how excellent this engine was and how strong its performance. If Wu Zhishi was really equipped with such an engine, what would happen?

Seeing Feng Zhengqi keeps talking about how good the turboshaft D engine is, how excellent it is, and how strong the power is.

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

Li Tianfeng smiled and it seemed that his engine was really good, and he actually received such a good review from the test pilot.

Feng Zhengqi stood at attention and said loudly: "Yes, I'm talking about the main one."

Then, Feng Zhengqi focused on a series of test flights, and said it in detail. Of course, he couldn't control the middle and talked about how excellent the turboshaft D engine is and how powerful it is. Seeing this, even Li Tianfeng couldn't help but smile.

After the test flight situation was introduced, as the chief designer of Wu Zhishen, Mr. Wu was also happy. He held Li Tianfeng's hand and said enthusiastically: "Mr. Li, with such an advanced and excellent engine, our Wu Zhishen is simply a big boom."

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

Li Tianfeng has such confidence. Li Tianfeng not only specializes in aviation engine design, but also is good at aircraft design. It is naturally no problem for armed helicopter design technology.

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

Zhang Haiping, who was standing by, can be said to be the military representative of this test flight. Zhang Haiping said: "Mr. Li, Mr. Wu, you have such a passion. I would like to thank you on behalf of our military."

As a senior officer of the General Staff Equipment Department, Zhang Haiping knew very well that the current domestic army, especially the army, urgently needed a powerful and advanced armed helicopter.

In the world, armed helicopters are often claimed to be the backbone of the army. The domestic army needs to stand up its solid and powerful backbone.

The Wuzhi Ten, equipped with a turboshaft D engine, conducted several test flights. According to regulations, a series of test flight subjects were completed. Li Tianfeng also stayed at the test flight base for several days before finally returning to Songzhou with satisfaction.

After staying at the test flight base for several days, Li Tianfeng and Dean Liu and others gradually became familiar with each other. Li Tianfeng and Wu Zhi's ten-face design staff, especially the chief designer Mr. Wu.

The two exchanged some technical matters. Li Tianfeng's many technical insights and advanced ideas made Mr. Wu's eyes lit up. In the armed helicopter, Li Tianfeng's technical attainments made Mr. Wu admire him.

The test flight was very smooth and perfect!

Of course, Feng Zhengqi was also the first test pilot to be punished. He wrote a review and was confined. Strangely, Feng Zhengqi was still happy after being punished.

Someone asked in confusion, and Feng Zhengqi explained that with such an excellent turboshaft engine, our top ten martial arts engines have hope. Let’s write a review. What’s the point of being locked up for a few days?

During the lockdown period, Feng Zhengqi was still savoring the feeling of this test flight, as if he was still unsatisfied, especially when he recalled that the engine had a strong power and excellent performance, Feng Zhengqi would also happily wave his fist in the lockdown room and excitedly.

Li Tianfeng and Qiu Wen'an returned to Songzhou with satisfaction, and Zhang Haiping also brought the test flight report at this time, happily returned to the process, and immediately gave a detailed report to his minister.

...

Tianfeng Technology Company.

On the test drive table, the 2,000-hour life test drive of this engine has been underway. It is two shifts during the day and night. In order to seize the time, Li Tianfeng did not waste his time at night.

On the first day back to Tianfeng Technology, Li Tianfeng and Qiu Wen'an went to the test workshop specially. After seeing the test run, Li Tianfeng felt very relieved when he saw that everything was normal.

Because the turboshaft D engine has been designed and has obtained a model certificate and is applying for a production license, it is impossible to make major changes in 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 each part was basically completed and the inspection was passed and the central warehouse was entered. The engine assembly work was already underway.

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

Tianfeng Technology is focusing on production, and the company's operations are orderly and showing vitality. Now Tianfeng Technology Company has a sound organization, with basically full employees and more than 6,000 employees.

The nine manufacturing workshops, plus the assembly workshop and the test workshop, have the largest number of front-line workers, almost nearly 4,000. In addition, there are all kinds of technical personnel, including engineering and technical personnel and designers. There are nearly 2,000 of these personnel, of which more than 1,000 designers are.

What remains are management personnel, auxiliary personnel, including logistics and security personnel, and these personnel are only in just over a thousand.

The company is booming, and with the about to obtain a production license, Tianfeng Technology Company, from Li Tianfeng, is full of confidence and motivation.
