Chapter 525: Advanced Stealth Materials
The "Black Ghost" UAV adopts an advanced aerodynamic layout, extensive use of Hercules materials, two turbofan 21B engines with excellent performance, advanced on-board equipment, and excellent stealth performance.
Advanced stealth performance is required, not only considering the shape design of the aircraft, but also spraying stealth materials.
The stealth materials that will be used in the "Black Ghost" UAV are developed by Tianfeng Technology Company itself, and the experts from the Materials Engineering Center are responsible for the research and development tasks.
Hercules materials are also the masterpieces of experts from the materials engineering center, and now, stealth materials have also been successfully developed and are undergoing performance tests.
Of course, whether it is Hercules materials or the current stealth materials, they are inseparable from Li Tianfeng, if it were not for Li Tianfeng's technical guidance, with everyone's strength, it would be absolutely impossible to successfully develop it.
The B2 bomber of the United States, the frontal radar reflection cross section is about 0.1 square meters, and our J-20 fighter is basically this data, and the American F22 fighter has excellent stealth performance, which is estimated to be about 0.05 square meters.
The radar reflection cross-sectional area of the "Black Ghost" UAV is 0.03 square meters proposed in the design outline, and such a small radar emission cross-section, in addition to the advanced shape design, requires very advanced stealth materials, that is, absorbing materials.
The "Black Ghost" drone not only has excellent stealth performance, but its infrared signal strength is also one level lower than that of the F22 fighter, that is, the "Black Ghost" drone has excellent infrared stealth effect.
If this drone is really developed, it will be a veritable black ghost, which will simply come and go without a trace.
No wonder, when I saw the technical outline of the design of this UAV, the military would attach so much importance to it. Even Mr. Wei was shocked.
Several experts from the Materials Engineering Center also know the importance of stealth materials to the "Black Ghost" drone, and they are seriously testing.
After a busy time, everyone's mood was slightly nervous, because everyone knew that the test results would be available soon.
A middle-aged expert wearing black-rimmed glasses operates the inspection equipment himself. The rest of the experts gathered around, and everyone looked intently at the data display of the test equipment.
On the test equipment, the detection data appeared on the LCD screen, and everyone was an expert in stealth materials, so they naturally saw the significance of these data at a glance.
It worked!
Definitely a success!
Compared with the last time, the data has been greatly improved, and everyone's tense and high-hanging heart will fall to the ground at once. Everyone's faces were no longer worried and nervous, full of excitement and joy.
"Lao Zhang! We did it! ”
"Yes, we succeeded, absolutely succeeded! Look at this data, if our 'Black Ghost' uses this stealth material that we have successfully developed, the radar launch cross-sectional area is definitely below 0.03 square meters! ”
"Haha, such stealth material. Even the old United States will definitely find it difficult to spot our planes! ”
“……”
Everyone was in high spirits. They are all old people, almost jumping up like young people, the eldest Lao Zhang, a senior materials expert in the materials engineering center, said loudly while being happy: "Quick." Report back to the Director! ”
Li Tianfeng soon received a call from the director of the Materials Engineering Center, and Li Tianfeng was very happy to hear the good news.
At the beginning, Li Tianfeng was at the base in the south of the city, and was talking to Zhou Ding and Li Dawu. Lei Yong and others held a meeting and were discussing the technical issues of some UAVs, as well as the progress of development.
After answering the call, Li Tianfeng said happily: "Let's go, let's go to the materials engineering center, our stealth materials have been successfully developed!" ”
The three of them glanced at each other, obviously happy, especially Lei Yong, as the deputy chief designer, Lei Yong took the successful development of the "Black Ghost" UAV as his life goal.
The excellent stealth performance of this UAV is also very desirable to Lei Yong, and Lei Yong is obviously a little excited to learn that the stealth material has been successfully developed.
Everyone drove all the way to the headquarters of Tianfeng Technology Company, and walked directly into the materials engineering center, and in the laboratory, Li Tianfeng personally looked at the testing data of this material.
After reading these data, Li Tianfeng knew that the stealth material was successfully developed, and compared with the last time, it has been greatly improved, and it has basically met his own mental requirements.
Li Tianfeng waved his hand happily: "Immediately start preparing for the mass production of this material, our drone finally has qualified stealth materials." ”
The laboratory was successfully developed, and then it was able to be mass-produced, and there was a process in between, so Li Tianfeng asked to start preparing for mass production immediately.
Li Tianfeng said to several material experts: "You have contributed a lot to the successful development of this stealth material, and I want to reward you heavily!" ”
Lao Zhang said modestly: "Mr. Li, the success of stealth materials is mainly due to your technical guidance. ”
In any case, Li Tianfeng still rewarded these material experts, and Li Tianfeng said that the heavy rewards were generally six-digit cash rewards.
In the development of various engines in the past, especially in the development of advanced engines such as turbofan 21 and turbofan 25, the number of people who received heavy awards was in double digits. Such a reward has also greatly mobilized everyone's enthusiasm.
The "Black Ghost" UAV, the aerodynamic design has been completed, the structural design has been completed, the avionics system design is progressing smoothly, and the stealth material has been successfully developed, which makes Li Tianfeng look forward to this UAV more and more.
In fact, Li Tianfeng is not the only one who is looking forward to this drone, and even the top of the military is no exception.
Capital.
In Mr. Wei's office, Mr. Wei is listening to Zhang Haiping's special report, which is basically once a month.
Mr. Wei is very busy, and it is very rare to be able to take the time to listen to a special report on the "Black Ghost" drone once a month, which shows Mr. Wei's expectation and attention to such a drone.
After listening to Zhang Haiping's report, Mr. Wei stood up and asked loudly: "Minister Zhang, Tianfeng Technology Company has even successfully developed the stealth materials of the drone!" ”
Zhang Haiping said: "Yes, it has been successfully developed, and Li Tianfeng said, this stealth material is at the world's leading level, after our 'Black Ghost' UAV uses this material, its shadow performance is above the F22 fighter in the United States, and most of the world's radars don't want to find our UAV." ”
Mr. Wei said happily: "Okay, great! ”
It can be seen from Mr. Wei's expression that Mr. Wei is not only happy, but also excited, as such a high leader, one of the main responsible persons of the military, Mr. Wei has long been able to collapse Mount Tai in front of him without changing his face.
Like just now, with obvious joy and excitement on his face, this is very rare, in Zhang Haiping's impression, Mr. Wei has not been like this for a long time.
It can be seen that Mr. Wei's mood at the moment, after calling "good" twice in a row, Mr. Wei said: "I don't know what the effect of our J-20 fighter will be when it uses this stealth material produced and developed by Tianfeng Technology Company." ”
Zhang Haiping said: "This needs to be known after asking Li Tianfeng." ”
Mr. Wei waved his hand and said: "Minister Zhang, you ask Li Tianfeng, can this stealth material be used in our J-20 fighter, and after using it, what is the stealth effect of J-20?" ”
Sure enough, after the report was completed, Zhang Haiping immediately called Li Tianfeng and asked about the matter carefully.
Li Tianfeng replied that there is no problem at all with the J-20 fighter, but the shape design and aerodynamic design of the J-20 are relatively conservative, which has greatly reduced the effect of this material, although the stealth effect has been improved to a certain extent, but it is of little significance.

Tianfeng Technology Company.
The turbofan 21B engine is only a modified design on the basis of the original turbofan 21 engine, and the workload is not large, and now, the first turbofan 21B engine has entered the high-altitude platform test.
The ground test of this turbofan 21B engine was very smooth, and the performance was as good and perfect as the turbofan 21A engine.
The high-altitude platform test is the real test of this engine, the test control room, Sun Xiaoping and Qiu Wenan came in person, and the engine has started the test run of various high-altitude states in the high-altitude platform.
10,000 meters of altitude of various states of simulation test, 15,000 meters of altitude state simulation test, and now, into 20,000 meters of altitude state simulation test.
The "Black Ghost" UAV is a high-altitude UAV, which is designed to cruise at an altitude of 20,000, which is 2,000 meters higher than the Global Hawk UAV in the United States.
20,000 meters of altitude state simulation test!
In the high-altitude test bench, the state of 20,000 meters in the altitude is simulated, the air pressure is reduced, the air is very thin, and the temperature is reduced, reaching dozens of degrees below zero, which is no different from the real 20,000 meters altitude.
In the test control room, everyone was quiet, only the sound of engine work came, and at this moment, a cruise at an altitude of 20,000 meters was being simulated.
Sun Xiaoping looked through the huge glass of the test control room to see the engine on the test bench, and then looked at the parameters on the display screen of each equipment in the test control room.
Sun Xiaoping knows that the design of the "Black Ghost" UAV is progressing very quickly and smoothly, and the aerodynamic design, structural design, research and development of stealth materials have been completed, and even the design of the avionics system is almost complete.
