A test flight base.

The test flight of Wuzhi 10 is generally carried out here, on the apron, you can see two or three Wuzhi 10 are quietly parked there, and in the helicopter hangar on the side of the apron, several maintenance personnel are doing the final inspection work on a Wuzhi 10.

Feng Zhengqi didn't think that he was fortunate to be sent to participate in the test flight mission, and it was Xiao Zhou who partnered with him, and the two of them carried out helicopter test flights many times, which can be regarded as a tacit understanding.

Today's Wuzhi 10 test flight, obviously a little different from before, on the side of the apron, there are already a lot of people, there are a lot of military people, and there are also a lot of Wuzhi 10 design and development personnel, several of them, it seems that they are forty or fifty years old, is the chief designer and deputy chief designer of Wuzhi 10.

A military off-road vehicle drove over from a distance and stopped in front of everyone, and it was Zhang Haiping, Li Tianfeng, and Qiu Wenan who got out of the car.

Today's Zhang Haiping is no longer dressed in casual clothes, but looks very formal, wearing a straight major general's uniform, and walks over.

The military representatives who came here early immediately greeted them, led by a colonel, and the colonel comrade greeted him and said enthusiastically: "Director Zhang, you have come here in person." ”

The two sides exchanged a few polite greetings, Zhang Haiping introduced them, Li Tianfeng, Qiu Wenan and several military representatives shook hands one by one, and Comrade Colonel also introduced the chief designer and deputy chief designer of Wuzhishi to Li Tianfeng one by one.

After everyone shook hands, they chatted politely and knew each other.

Zhang Haiping said: "Dean Liu, how are the preparations for the test flight?" ”

Senior Colonel Comrade Liu Zhifang, that is, Dean Liu, immediately said: "Director Zhang, the preparations are ready, and the test pilots are also ready. Test flights are ready for now. ”

Zhang Haiping nodded, and Li Tianfeng was a little happy in his heart, and even a little excited, this was the first field test flight of the turboshaft D engine, and it was still equipped with the Wuzhi 10 engine test flight.

The chief designer of Wu Zhishi next to him said: "Mr. Li, your vortex D is very well designed. The interface size of the engine is exactly the same as that of Wu Zhishi, and it doesn't take much to install two turboshaft D on the helicopter, and the size matches well. ”

Li Tianfeng smiled, "Mr. Wu, our vortex shaft D is positioned in Wuzhi Shi, and we have already considered it in terms of interface size design. ”

After the two chatted for a few words, the test flight was about to begin, and not far away, the door of the helicopter hangar slowly opened. Looking inside from the gate, I saw a brand-new Wuzhi Shi quietly parked in the hangar, a tractor slowly drove into the hangar, and several ground staff slowly dragged the helicopter out of the hangar with a tractor.

In everyone's eyes, the tractor dragged the helicopter slowly to the designated area, and then the tractor slowly left. The helicopter was silently parked in the distance.

Naturally, this helicopter has been replaced with two turboshaft D engines. As soon as the order is given, the flight test can be carried out immediately.

Li Tianfeng saw the Wuzhi 10 helicopter, took another look at the vast test airfield, and raised his eyes to look at the blue sky, the sky was clear, and the visibility was very high. It was a difficult good weather.

Farther away from the test site, there was also a Wuzhijiu parked, and in the distance, surrounded by high barbed wire, according to Li Tianfeng's good eyesight. You can only vaguely see the barbed wire fence several meters high.

Blowing slightly, although it has entered summer, because it is eight or nine o'clock in the morning, the weather is not hot, on the contrary, the breeze blows and there is a trace of coolness.

The test flight is about to begin!

The test flight commander issued a test flight order, and the two test pilots who had long been ready to go were Feng Zhengqi and his partner Comrade Xiao Zhou.

Open the hatch, enter the helicopter, sit in the cockpit, put on the helmet, turn on the instrument, operate in an orderly manner, completely in accordance with the regulations, and hear the instructions from the headset, the two started the helicopter.

The gauge is normal!

The display is normal!

Engine start!

With a series of operations, the helicopter began to work, the sound of the engine working came, the helicopter rotors rotated and accelerated, and the strong air flow blew on the ground, which was originally very clean on the concrete floor, but under this strong air flow, only a little dust was blown up.

From afar, watching the helicopter start and preparing for a test flight, Zhang Haiping, Qiu Wenan, including Wu Zhishi's designers, everyone's eyes looked at this helicopter, and even, some people's heartbeats accelerated slightly.

It's about to take off!

As a test pilot, Feng Zhengqi was slightly excited at the moment when he began to board Wuzhi Shi, and now, with the start of the helicopter, the sound of the helicopter working normally was heard in his ears, and Feng Zhengqi quickly carried out the state.

"One qiē is normal! You can take off! ”

"Take off, test flight according to the predetermined subjects!"

Hearing the instructions from the headset, Feng Zhengqi gently pushed the operating stick, and the helicopter slowly left the ground, a few meters above the ground, there was a short hover, and then quickly flew towards the sky.

Take off!

Seeing this scene, Qiu Wen'an was excited and excited, as the chief designer of the turboshaft D engine, Qiu Wenan also paid a lot, and at this moment, this qiē effort seems to have been reported.

Qiu Wenan found that his eyes were slightly moist, looking at the helicopter in mid-air, his eyes were hazy, and when no one was paying attention and everyone was staring at the helicopter, Qiu Wenan quietly wiped his eyes.

Li Tianfeng's mood at the moment, how can he not be excited, thinking of all the things in the development process of the turboshaft D engine, thinking of the efforts he has made for it, Li Tianfeng is a little embarrassed.

Picking up the binoculars, Li Tianfeng clearly looked at Wu Zhishi in mid-air, at this moment, Li Tianfeng found that this helicopter was so eye-catching, not only Li Tianfeng, but everyone's eyes were attracted to this helicopter.

Throughout the test flight base, almost all the people, everyone is looking at this helicopter, including the base staff, ground staff, maintenance personnel, and technicians.

As we all know, today is the first field test flight of the turboshaft D engine, and we already have a basic understanding of this engine, knowing that this is the latest and very excellent engine.

"Lao Li, it's really exciting!"

"Yes, it's the latest domestic turboshaft engine! Terrific! ”

"The plane took off normally, and it seems to be at ease!"

"Yes, yes, you listen to the sound of this helicopter, how nice it is!"

In the entire test flight base, everyone looked up at the helicopter in mid-air, everyone's eyes, colorful, everyone looked at the helicopter, and their hearts were excited!

In everyone's eyes, the helicopter hovered in mid-air, and then began a series of test flight maneuvers.

"Look! It's a fast climb! ”

"Oh my God, it's so exciting to actually fly upside down!"

"Look, it's beautiful!"

Seeing a series of test flight actions of the helicopter in the air, everyone on the ground shouted excitedly, and even cheered, even the personnel of the test flight base, everyone generally rarely saw such a wonderful test flight.

Li Tianfeng held the telescope, saw more clearly, saw this series of test flight actions, smiled lightly and happily, the engine performance was excellent, and the power was full.

These test flight actions were agreed upon in advance, and now, a series of actions are displayed in front of everyone's eyes, and at the same time, many people are happy and excited in their hearts.

As the chief designer of Wu Zhishi, he has been limited to engine power, and the design of the helicopter has been restricted by a large range, and now, seeing the two turboshaft D engines installed in the helicopter, a series of test flights, the surface can be called perfect, Mr. Wu is even more excited.

Even, at this moment, I think of the subsequent upgrade of Wuzhi Shi, with such an excellent engine, Wuzhi Shi can be transformed into a jump, from a medium-sized armed helicopter to a heavy armed helicopter, and a multiple-fold jump in performance.

Mr. Wu was excited, and couldn't help but look at Li Tianfeng a few more times, his eyes were full of joy and excitement, and there was even a trace of gratitude to Li Tianfeng.

Wu Zhishi in the test flight, a series of test flight actions in the air, because the air condition is good, blue sky and white clouds, visibility is very high, even without binoculars, everyone can basically see the situation of the helicopter, with one action after another, everyone cheered and cheered.

"Beautiful!"

"Wonderful!"

"It's so enjoyable!"

Everyone cheered one by one, today you can see the Wuzhi 10 test flight equipped with the turboshaft D engine, everyone is too addicted, if you are allowed to take pictures, there will definitely be many people who will take out their mobile phones to take pictures of this wonderful moment.

However, limited to the need for confidentiality, photography is not allowed, everyone can only be addicted to this way, even so, everyone is very satisfied!

"Oh my God, look, what a move that is!"

"It's so exciting!"

Everyone saw the helicopter in the air, came to a beautiful flight action, everyone opened their eyes at the same time, and immediately exclaimed happily, this series of actions, it is really beautiful, too exciting, many people are seeing it for the first time.

"Oh my God, that's the Levisman reversal, it's the Levisman reversal!"

"Really, I can't believe it's really Levessman reversed!"

Li Tianfeng held the binoculars, saw very clearly, saw Wu Zhishi's movements, his heart was excited, he didn't think about it, he actually played such a beautiful action, Li Tianfeng secretly applauded in his heart, the level of this test pilot is very high, and ordinary people really can't play such beautiful and difficult actions.

At the same time, Li Tianfeng was slightly puzzled in his heart, there was no such test flight action on the test flight outline this time!
