Tianfeng Technology Co., Ltd., Commissioning Engineering Center.

In the huge test control room, everyone kept quiet, only the sound of the engine working, and the LCD screen of the test console was displaying the parameters of the test.

This is a 20,000-meter high-altitude test run, and this turbofan 21B engine is simulating high-altitude cruise, which is completely similar to the real situation at 20,000 meters.

Many people, slightly nervous in their hearts, know that this is the real test of the engine, even Sun Xiaoping is not excluded, from time to time to look at the test data on the display screen, and through the huge glass to see the engine that is working.

Minute by minute......

After a full hour, Sun Xiaoping quietly breathed a sigh of relief, and glanced at Qiu Wenan next to him, and there was no worry and nervousness in the eyes of the two, but happiness and relaxation.

Several test drivers also began to report loudly, and the voices rang in everyone's ears one by one.

"The engine is working fine!"

"Fuel consumption is normal!"

"The vibration is normal!"

"No icing in the engine!"

“……”

In the test monitoring room, soon a burst of cheers sounded, and the young test engineers and technicians, as well as the young test drivers, everyone jumped up happily, cheered vigorously, and shouted.

Sun Xiaoping let out a long sigh of relief, and then said: "Old classmate, we have basically succeeded, and our turbofan 21B engine will become an excellent power for the 'Black Ghost' drone." ”

Qiu Wenan also said with a sigh of relief: "Yes, our turbofan 21B engine has performed well after a series of test runs, especially the 20,000-meter high-altitude cruising simulation test just now, the performance is very good, and I am also full of confidence in the turbofan 21B." ”

Sun Xiaoping said: "20,000 meters in the air. Dozens of degrees below zero, our turbofan 21B engine does not have the slightest icing, which shows that our anti-icing design is also first-class. ”

The two looked happy, chatted, and seemed very satisfied with the turbofan 21B engine. In the test monitoring room, those test technicians. It is also relished, and the turbofan 21B engine is full of praise.

The engine completed a series of high-altitude simulated test runs, performed well, successfully passed various tests, and the engine gradually stopped, and it was quiet.

Sun Xiaoping waved his hand and said, "Let's go, let's take a look at our engine that has just completed the test run." ”

Qiu Wenan nodded and walked out side by side with Sun Xiaoping, and everyone followed and walked into the huge high-altitude test bench together. Walked up to the turbofan 21B engine.

This engine was lying quietly on the test bench, Sun Xiaoping looked at it with satisfaction, and even made an amazing move, directly touching the tail spray cover of the engine with his hands.

When the engine is working, hot hot gas is sprayed from the tail jet, creating a huge thrust, incidentally. The tail spray part is also hot, if the test time is relatively long. If the light is dim, you can even see that the tail spray is red and hot.

The turbofan 21B engine has been tested for several hours, and now, the engine has just stopped, and the tail spray position is also scorching, like a red-hot soldering iron.

One of the closest test drivers to Sun Xiaoping. Seeing this, he shouted loudly: "Mr. Sun, no!" ”

But I was still afraid of it, Sun Xiaoping had already touched the tail spray cover of the engine with his bare hands, and many people. I couldn't bear to close my eyes, and the picture of green smoke rising and being scalded came to my mind.

Surprisingly, nothing happened, which surprised everyone, and with an unbelievable face, Sun Xiaoping smiled, touched the tail spray cover of the engine and said: "It's okay, it's okay, it's just a little warm." ”

Is it just a little bit of warmth?

Everyone didn't believe it, as long as Qiu Wenan smiled and didn't say anything, he also took two steps forward, reached out and touched the tail spray cover of the engine, Qiu Wendao: "Well, it's good, it fully meets the design requirements." ”

Everyone, you look at me, I look at you, the performance of Sun Xiaoping and Qiu Wenan completely subverted everyone's conventional understanding, and everyone couldn't understand that after such a long test run, why didn't the tail spray cover be hot?

Sun Xiaoping glanced at everyone, and then said with a smile: "Don't be surprised, one of the differences between the turbofan 21B and the turbofan 21A engine is that the parts of the tail spray have been designed and improved, just like this tail spray cover, there is a layer of heat insulation coating on it, so it will not be hot at all." ”

Hearing Sun Xiaoping say this, a few bold people stepped forward and touched the parts of the engine's tail spray with their bare hands, and everyone was surprised, and one of them said loudly: "Sure enough, it's not hot at all, just a little warm." ”

Sun Xiaoping nodded and said loudly: "Our 'Black Ghost' UAV not only has excellent radar stealth performance, but also has excellent infrared stealth, and the high-temperature engine in work is a very obvious infrared source, so we have carried out special treatment on the engine in order to reduce its infrared radiation." ”

Qiu Wen'an, who rarely said a few words, also took over the conversation and said: "Our 'Black Ghost' UAV, the infrared radiation of the turbofan 21B engine is very small, and its infrared stealth effect is the world's top. ”

Listening to Sun Xiaoping and Qiu Wen'an, the excellent stealth performance, coupled with the top infrared stealth performance, everyone was happy and confident.

………

In the office, Li Tianfeng listened to Sun Xiaoping's special report, the performance of the turbofan 21B engine, a series of test runs, including high-altitude test runs, etc., Sun Xiaoping made a detailed report.

Li Tianfeng said: "Mr. Sun, our turbofan 21B engine has been successfully developed, and our 'Black Ghost' UAV will have a qualified power from now on." ”

Turbofan 21B engine, Li Tianfeng can be said to be very understanding, this engine at the beginning of the modification design, Li Tianfeng carried out technical checks, and now, the test is successful, Li Tianfeng knows that his UAV has excellent power.

Sun Xiaoping said happily: "Boss, the turbofan 21B engine has been successfully developed, and we have completed a relatively large job." ”

Li Tianfeng nodded, "The development of our 'Black Ghost' UAV has also made most of the progress, and what I am looking forward to most now is the early production and development of the first 'Black Ghost' prototype." ”

Sun Xiaoping said: "Boss, the various airborne equipment of the UAV, such as synthetic aperture radar, high-definition camera equipment, and defensive electronic countermeasure systems, have been successfully developed. ”

Li Tianfeng said happily: "Although the requirements for these airborne equipment are very high and the technical content is not low, the research and development work is progressing relatively smoothly, and the design and development work is basically completed quickly." ”

Sun Xiaoping said in surprise: "Boss, this is great, in this way, our first 'Black Ghost' drone is just around the corner!" ”

Li Tianfeng said happily: "Yes, it shouldn't take long!" ”

Seongnam base, design and R&D center.

The design and development of the avionics system of the "Black Ghost" UAV has finally come to fruition, which is a major research result after the successful development of the turbofan 21B engine.

The experts of the R&D and design center, in accordance with Li Tianfeng's instructions, developed an avionics system R&D platform, on which the R&D work of the "Black Ghost" UAV avionics system was completed, and the design of the avionics system was basically completed.

In the design and R&D center, Li Tianfeng also has an office, and if he comes to the Chengnan base to work, Li Tianfeng is in this office.

Sitting at his desk, Li Tianfeng carefully looked at the design drawings of the avionics system that had been completed on the computer.

First of all, I looked at the general design drawing, the schematic diagram, and then looked at a series of other design drawings about the avionics system, and looked at it for almost a day.

Approaching the end of work, Li Tianfeng got up, rubbed his temples, on the computer, there is a document established by Li Tianfeng, which is full of places that need to be improved and perfected, and Li Tianfeng also put forward a lot of suggestions and opinions on the design of the avionics system.

Li Tianfeng's office was on the upper floor of the office building, rubbing his temples, Li Tianfeng walked to the large floor-to-ceiling window of the office, and through the glass, he could see far away.

Looking out, there were huge factories one after another, and there was no edge in sight, and the farthest factory building, Li Tianfeng estimated that the straight-line distance from him was more than 1,500 meters.

Farther away, it is the airport belonging to Tianfeng Technology Company, which belongs to the supporting facilities of the Chengnan base, where the aircraft developed and manufactured will be tested and tested at the airport.

The preliminary construction of the airport has been completed, and the construction of ancillary facilities is also nearing completion.

Li Tianfeng thought in his heart that it is estimated that in a few months, our "Black Ghost" drone will take off here and fly to a high altitude.........

………

In the golden autumn of October, the osmanthus is fragrant.

In the production and manufacturing base in the south of the city, the charming fragrance of osmanthus wafts everywhere, and some assembly workers are busy in the No. 1 assembly plant.

The first static testing machine of the "Black Ghost" UAV is being assembled, and the static testing machine, as the name suggests, is used to conduct static tests in order to verify the scientificity and rationality of the design and test the force of each structural part.

Li Tianfeng, Zhou Ding, Lei Yong and others put on clean cotton shoes, and after the wind bath, everyone walked into the interior of the assembly plant together.

Walking into the huge factory, the first thing everyone saw was the "Black Ghost" drone being assembled, and when they saw this aircraft, everyone couldn't help but speed up their pace.
