A few days later, in the morning, several Warrior military off-road vehicles drove over from Maple Leaf Avenue not far away, and then the convoy stopped in front of the factory of Huake Aviation Technology Company.

Zhang Kelong stepped down from the car at this time, and when he saw Yang Jie, he also had a smile on his face, and then shook hands with him who came up.

After a few words of greeting, Zhang Kelong said: "Don't say anything, let's go, let's go directly to the assembly workshop, let's see what good things you have come up with." ”

On the static test bench of Huake Airlines, a yellow-skinned machine like a giant bat-like drone is quietly placed on the test bench at this time.

At this time, the fuselage wing and other parts are fixed by hundreds of electro-hydraulic loading systems, and the fuselage is not equipped with measurement sensors, which continuously transmit the displacement and stress changes of the fuselage components to the host system.

Zhang Kelong saw that the drone on the test bench was almost 20 meters wide, more than 10 meters long, and the entire height was close to three meters, and the whole appearance was very similar to the American Ghost 2 stealth bomber.

"This ...... This is your own stealth drone?"

Zhang Kelong's eyes widened.

"Yes, I didn't expect Chief Designer Zhang Hong to be very fast, and it only took about a year to design and manufacture the prototype of the Shadow Stealth UAV. ”

Yang Jie said with a smile.

In fact, Zhang Hong led the design team to do the research and development of the aerodynamic layout of stealth UAVs a few years ago, and he is experienced in aerodynamic layout.

After Zhang Hong entered Huake Aviation Technology Company, he did not forget the stealth drone project while developing the Eagle and Rainbow UAVs, and also reported to the headquarters, Yang Jie also approved the project and allocated sufficient funds.

Zhang Kelong grabbed Yang Jie at this time, stared at Yang Jie and asked, "Have you solved the technical problems of the stealth coating?"

"Oh, our communication expert company in order to solve the experimental terahertz radar communication dark chamber absorbing materials had to develop their own silicon carbide absorbing materials, it took almost two years to develop the full radio wave absorbing materials, in solving the full radio wave anechoic chamber absorbing materials but also to solve the technical problems of UAV stealth coatings. ”

Yang Jie said with a smile: "When this shadow stealth drone is tested in the dark wave room, the conductive polymer material in the absorbing material will convert radar waves into electrical energy, and the radar wave absorption efficiency of different types of waveforms is different, and now there are too many types of radars in the world, and we cannot guarantee that we can achieve complete stealth in front of all radars." ”

"The stealth coating we developed is the best in the microwave radar absorption efficiency, and the radar wave effect in the long-wave radar is relatively poor, but we are already developing materials with good radar absorption efficiency for the long-wave radar, and then improve the coating. ”

Yang Jie said.

"You should have more than one prototype like this, right? Hurry up, take me to the assembly workshop to see the other prototypes, I want to see what the stealth paint you have developed looks like!"

After Zhang Kelong finished speaking, he dragged Yang Jie to the final assembly workshop.

Zhang Hong on the side and Song Fuxiang of Hongdu Group Company also secretly smacked their tongues when they saw this scene, Zhang Kelong is the minister of the General Armament Department, a real lieutenant general, at this time he pulled Yang Jie without putting on a show, which shows the close relationship between this general and Yang Jie.

Song Fuxiang was also secretly happy in his heart, the attitude of the military leaders towards the Hongdu Group Company was very cold, the military's research and development funds were basically given to Cheng Fei and Shen Fei, and the Hongdu Group Company was lined up to the corners, if it were not for the Hongdu Group Company relying on export training aircraft and attack aircraft to support, it might have starved to death.

A few years ago, Hongdu Group and Huaxing Group began to cooperate, Hongdu Aviation Group Company has made a lot of money in the past two years on fuel cell motorcycles, and in the first half of this year, two million electric two-wheeled vehicles were sold, and the revenue reached more than 6 billion!

After the surge in income of Hongdu Group Company, more money began to be invested in the technology research and development of aircraft products, such as stealth drones such as Shadow and supporting weapons and equipment such high-tech equipment, Hongdu Group naturally attaches great importance to it.

While the "Shadow" UAV is doing ground static tests, the assembly workshop is also assembling several other prototypes.

The main beam of the aircraft has been firmly placed on the assembly bench, and the assembly workers are installing the structural parts.

Yang Jie and Zhang Kelong, accompanied by Song Fuxiang, Zhang Hong and others, came to the assembly workshop.

Li Jianwu, chief engineer of the assembly department, said to Yang Jie: "Yang Shao, the assembly is relatively smooth, and the aircraft will be able to complete the overall structural assembly in the afternoon and begin to enter the next step of the assembly work." ”

After the structural assembly is completed, before the avionics system is installed and the airborne equipment is installed, the engineering prototype will also be sent to the paint shop for overall spraying, including the coating of stealth materials.

Zhang Kelong saw that these assembly engineers were busy, but he did not urge to speed up the progress.

Yang Jie said to him, "Then wait a few more hours?"

Zhang Kelong nodded: "The assembly work is very important, there can be no mistakes, or according to your current assembly rhythm." ”

Yang Jie and Zhang Kelong watched everyone's assembly at this time, only to see the workers, loading a structural part onto the main beam of the aircraft, aligning the mounting holes, tightening the nuts, and tightening in strict accordance with the tightening sequence and torque requirements required by the process.

Such an assembly must not be sloppy, and there are very strict technical requirements, such as the tightening of nuts, not only in sequence, but also in tightening torque requirements.

Technicians use torque wrenches to tighten them one by one according to the process requirements, and after the installation of this structural part is completed, they carefully check whether they meet the requirements of the assembly process.

After the assembly of parts is completed, there are technical conditions and assembly size requirements, and they need to be checked one by one. If the assembly requirements are not met, it needs to be reassembled or adjusted.

Some of these standards are the standards of Hongdu Group Company, and some are the production standards of Yonghan Aviation Technology Company and Fokker Company, and the technical department has also unified these standards, and the production standards and process specifications are extremely strict.
