At ten o'clock in the morning, Zhang Haiping arrived at Tianfeng Technology Company by car.

Shortly after Li Tianfeng arrived at the factory gate, a military off-road vehicle drove from Songzhou Avenue not far away, and the off-road vehicle stopped in front of the factory gate of Tianfeng Technology Company.

Zhang Haiping only brought one entourage, and when he saw Li Tianfeng, Zhang Haiping smiled heartily, walked over quickly, and greeted Li Tianfeng like an old friend.

After a few words of greeting, Zhang Haiping said: "Mr. Li, it's approaching the end of the year, I'm too busy, let's go, let's go directly to the assembly workshop, and we won't be free of tea." ”

Li Tianfeng smiled and said, "Minister Zhang, that's okay, let's go to the assembly workshop first." ”

Li Tianfeng and Zhang Haiping walked into the assembly workshop side by side, and saw hundreds of assembly workers in the assembly workshop busy and in full swing, Zhang Haiping smiled slightly and nodded.

Zhang Haiping knew that there were several models assembled at the same time in this assembly workshop, so looking at the past, Zhang Haiping saw the turbofan 16, turbofan 17, as well as turbofan 20 and turbofan 21, and also saw the turbofan 25 engine that made Zhang Haiping's heart hot.

"Mr. Li, that's our turbofan 25 engine!"

Li Tianfeng smiled and nodded: "Minister Zhang, that is our turbofan 25 engine, after a few days of parts assembly, it has now been put on the final assembly bench and is starting the final assembly." ”

Hearing what Li Tianfeng said, Zhang Haiping couldn't help but speed up his pace involuntarily, and walked quickly to the side of the turbofan 25 engine, which had been assembled for most of the time.

"Tsk, this is our turbofan 25 engine, it's really good!"

Zhang Haiping is very familiar with the performance of the turbofan 25 engine, but today is the first time to really see the engine and surround the engine. While watching, I was amazed and happy.

Li Tianfeng stood beside him, smiling silently, he didn't expect Zhang Haiping, who was a lieutenant general. The reaction would be so big today.

After watching it for more than ten minutes, Zhang Haiping stopped, and seemed to realize his gaffe just now, Zhang Haiping couldn't help but smile, "Mr. Li, I was so excited and happy just now." ”

The world's most advanced and outstanding performance of the small bypass ratio turbofan engine, Zhang Haiping is not excited. In the face of such an engine, if it is replaced by other senior military generals, it is estimated that it will be about the same.

Li Tianfeng smiled and nodded, expressing understanding, Li Tianfeng introduced: "Minister Zhang, by tomorrow afternoon, this turbofan 25 engine will be able to complete the final assembly, and the day after tomorrow will be ready to enter the test workshop for the first test run." ”

Zhang Haiping said: "Great. Great! After returning to Beijing, I will report to Mr. Wei as soon as possible. It also made Mr. Wei happy. ”

Several assembly workers next to him have basically seen Zhang Haiping, because Zhang Haiping has been to Tianfeng Technology Company many times, so everyone has not stopped their work.

When Zhang Haiping first came, everyone was installing the fan casing and looking for it. Leveling, setting the position, the fan casing is checked for correctness, and one of the workers first installs the precision positioning screws of the fan casing.

There are several precision screw holes on the side of the fan casing installation. After these precision positioning screws are installed according to the requirements, we check the table again, and then install other screws.

Zhang Haiping watched it with relish, and asked Li Tianfeng from time to time.

Zhang Haiping said: "Mr. Li, this is our Hercules material fan casing, it looks so exquisite!" ”

Li Tianfeng said: "Yes, this is the Fan Case, which is made of Hercules, compared with the titanium alloy case, the weight is about 30% lighter, the strength is more than twice as high, and the service life is also greatly enhanced." ”

Seeing the fan blades of the engine, Zhang Haiping said: "Mr. Li, you see how beautiful these fan blades are, they deserve to be the latest and most advanced blade design." ”

On the fan casing, a lot of engine accessories will be installed, including a large number of sensors, electronic components of the digital electronic control system, as well as a large number of pipes and wiring.

Zhang Haiping said: "Mr. Li, the electronic components of the turbofan 25 engine, as well as the entire digital control system, are all localized spare parts, if it was before, it is really unimaginable." ”

Some of these key and important spare parts are designed by Tianfeng Technology Company and manufactured by some very powerful large enterprises in China.

Zhang Haiping was full of interest, asked this and that, very happy, and even, Zhang Haiping said: "Mr. Li, if time permits, I really want to stay here all the time, and watch the assembly of this turbofan 25 engine be completed." ”

Li Tianfeng smiled, Li Tianfeng can fully understand Zhang Haiping's mood, for the turbofan 25 engine, the military has placed great hopes, and now, seeing that the harvest time is coming.

Next to this engine, Zhang Haiping stayed for more than an hour, from more than ten o'clock in the morning to more than eleven o'clock, and Zhang Haiping didn't seem to notice that time passed so quickly.

Li Tianfeng looked at his watch, and then said: "Minister Zhang, it's almost half past eleven, go, go to my office, I have a big surprise for you." ”

Big surprise!

Zhang Haiping was stunned at first, and then immediately became interested, because every time Li Tianfeng never disappointed Zhang Haiping, Li Tianfeng said that it was a big surprise, but he was afraid that it was a shocking surprise.

Zhang Haiping said: "Mr. Li, the turbofan 25 engine has entered the first prototype assembly so smoothly, which has already given me a big surprise, is there a bigger surprise than this!" ”

Li Tianfeng smiled mysteriously, and then said, "Minister Zhang, it's definitely bigger than this surprise, let's go, go to my office." ”

Seeing Li Tianmin say this, Zhang Haiping first looked at the turbofan 25 engine in assembly, and then stepped to follow Li Tianfeng, and the two went out of the assembly workshop together.

Li Tianfeng's office.

As soon as the two came in, they had just sat down, Liu Wei brewed hot tea, and took the best tea, Zhang Haiping was naturally a distinguished guest of Tianfeng Technology Company.

Taking a sip of tea, Zhang Haiping said, "Mr. Li, quick, let me see what the big surprise is." ”

Li Tianfeng smiled, opened his desk drawer, took out a bound book of materials from it, and raised the thing in his hand, Li Tianfeng said: "Minister Zhang, this is what I called a huge surprise." ”

Zhang Haiping said: "This looks like a design technical outline or something. Are you going to develop a new engine? ”

Li Tianfeng said: "This time it's not an engine, but an airplane. ”

Plane!

What kind of planes!

Suddenly, Zhang Haiping became interested, took over the design technical outline, and immediately flipped through the cover of the information. The big words "Black Ghost" are very eye-catching.

Looking at the cover, Zhang Haiping just took a brief look, and immediately became excited, and his face gradually flushed, and his hands trembled slightly.

It was a big surprise!

This is the technical outline of the design of a drone, this drone, named "Black Ghost" by Li Tianfeng, a haunting black ghost (note: this ghost is not the old beauty of B2).

The military urgently needed an advanced drone, at the beginning. Zhang Haiping is also one of the responsible persons, responsible for the development of a relatively advanced UAV, but, due to various technical reasons, this UAV died and failed to be developed.

Now, Li Tianfeng has sent a very advanced and excellent technical outline of the design of a drone to his hands. How Zhang Haiping was not excited.

After looking at it slightly, Zhang Haiping tried to calm his mood. said with emotion: "Mr. Li, I can't imagine that you have such strength to develop such an advanced UAV." ”

Li Tianfeng said: "We are seven or eighty percent sure. ”

Seven or eighty percent of the certainty, that is, there is a great degree of certainty, Zhang Haiping knows that Li Tianfeng generally does not speak big. Suddenly, Zhang Haiping was irrepressibly excited.

Zhang Haiping said: "Mr. Li, great, I want to take my design technical outline with me, and I will immediately return to Beijing to report to the leaders." ”

Li Tianfeng said: "Minister Zhang." After eating, it was almost noon. ”

Where did Zhang Haiping still have the heart to eat, he couldn't wait to fly to the capital immediately, Zhang Haiping stood up: "Mr. Li, I won't eat the meal, I'll leave now, and I'll go back to Beijing now." ”

Seeing this, Li Tianfeng smiled slightly, personally sent Zhang Haiping to the gate of the factory, and watched Zhang Haiping get in the car and leave.

It was not until Zhang Haiping's military off-road vehicle disappeared into the traffic on Songzhou Avenue that Li Tianfeng returned to his office.

Sitting in his office chair and drinking tea, Li Tianfeng's mind also thought about this drone, if nothing else, the military would soon issue a development task.

The preparation of the technical outline of the design of this UAV, at the beginning, Li Tianfeng only put forward some basic requirements, some basic technical parameters, and the specific details were all completed by the design and technical team led by Lei Yong.

At the beginning, Li Tianfeng gave Lei Yong three months, but Lei Yong didn't use three months at all, and it took more than a month to complete the first draft.

Li Tianfeng was undoubtedly very satisfied with Lei Yong's ability, because this first draft basically completely met Li Tianfeng's expectations, and was even better than Li Tianfeng imagined.

After Li Tianfeng's guidance and several revisions, this design technical outline was finally decided, and Li Tianfeng officially named this drone Black Ghost.

I hope it can come out of nowhere, come without a trace, go without a trace, and appear all over the world, Li Tianfeng knows that this drone really has this strength.

In the impression of ordinary people, drones are generally relatively small, and the "Black Ghost" is just the opposite, this is a super-large drone.

The black ghost is very large, on the one hand, it can carry a lot of fuel, on the other hand, those large electronic devices, large precision camera equipment can be carried, if the drone is relatively small, these big guys really can't be installed.

The drone is too small, so it can only be loaded with some simplified equipment that is relatively small in weight and volume, but cannot be loaded with large equipment.

The "Black Ghost" UAV has a wingspan of 42 meters, a length of 16.8 meters, a height of 4.8 meters, a maximum flight speed of 900 km / h, and a maximum take-off weight of 13,500 kg. The wingspan is larger than that of the Boeing 737, so the "Black Phantom" is a huge drone.

The Black Ghost carries more than 8 tons of fuel, has a maximum range of 30,000 kilometers, and has an autonomous flight time of up to 45 hours, allowing it to complete transcontinental flights.

This will be one of the largest drones in the world.

The advancement of "Black Ghost" is not in its hugeness, but in its advanced stealth effect, otherwise, how could Li Tianfeng name it "Black Ghost".
