Chapter 1448: New plan (1)

Lu Hesheng frowned.
"Zhenhua, what do you want this plane for?" he asked.
"Grandpa Lu, you can see from the appearance, this plane has only one purpose, what else can I use it for?" Tan Zhenhua asked knowingly.
Lu Hesheng said: "Of course I know what the purpose of this aircraft is. I just ask you, what is the purpose of developing such an aircraft? Are you planning to get an aircraft carrier back?"
"Aircraft carrier, Grandpa Lu, to be honest, it won't be long before there will be many on the market. It's easy to buy one for fun," Tan Zhenhua said without embarrassment.
"You really want to buy an aircraft carrier!" Lu Hesheng felt speechless, but after thinking about it, he felt that this matter didn't seem to have been revealed today. He had been fooled by this stinky boy as early as possible. When he returned to China, his ambition was revealed. Everyone remembers the "Luhe Student Enrollment" incident that sensationalized 3603. At that time, the "Flying Leopard" had just had a full-scale prototype. Tan Zhenhua It was proposed to transform a carrier-based aircraft on the basis of this aircraft. For this reason, a "pre-research group" was established at 3603, and the place to enter this "pre-research group" was still in the office. There has been a lot of fighting among the young people.
Today, this "pre-research group" is no longer what it used to be. In fact, under the powerful "consultants" of Lu Hesheng, the improvement plan of the carrier-based aircraft based on the "Flying Leopard" has been completed. The subject has turned into a substantial engineering development stage, which is part of the "Flying Leopard B" project plan for the first major modification of the "Flying Leopard" fighter.
It is necessary to introduce the major improvement plan of the "Flying Leopard B": the official project number assigned by China to this type of aircraft is "JH-7B". The project has been officially approved since the "Flying Leopard" passed the national acceptance. In other words, the main improvements include: changing to a more powerful "Qinling" engine that has been used as a "little mouse" with Haosha; changing the four-plus-degree digital-analog hybrid flight control system to a fully digital flight control system; upgrading the 1553b bus to The national military standard 289A (GJB289A) standard joint avionics system, the backbone network is upgraded from a coaxial cable to a wider bandwidth optical fiber, so as to achieve a data transmission rate of 50MB/S, which is 50 times higher than the previous model. The water gun has been upgraded to a large water pipe, so it has the ability to directly transmit the imaging of synthetic aperture radar SAR to the digital map; the scientific research results of the "873 project" realize the "national production of vitrified cockpit" and laser diffraction head-up display; airborne radar Upgraded from 1491 to 1493. The radar has replaced the domestic products with high-power grid-controlled traveling wave tubes imported from Russia and Russia and upgraded a new signal processing unit with faster processing speed, which makes the sidelobe of the radar work smaller and has better anti-interference ability. Strong.
Okay, let’s admit that although the people who clicked the wrong technology tree have been thrown 18 blocks away by the world's advanced level in the field of large-scale integrated circuits, they have made great achievements in the field of electronic tubes where they have worked hard. The performance of their high-power grid-controlled traveling wave tube is indeed much better than that of China’s domestic products. However, when Tan Zhenhua’s mother’s unit, 4055, planned to invest in this imported traveling wave tube, it was Tan Zhenhua stopped, but gave them another research direction...
In addition to these improvements, there is another point that needs special explanation-the "Flying Leopard B" plan does not include one fighter, but three!
The most basic of course is "JH-7B". Its current real number name is "JH-7BS", which basically inherits the aerodynamic shape and internal structure of the previous "JH-7". In addition to the improvements introduced above, it also The utilization rate of composite materials has been greatly increased. After upgrading a series of equipment and meeting the requirements of the China Air and Navy forces, the empty weight of the whole machine is actually lighter by 300 kg, which really makes the military overjoyed. .
The students who are familiar with the naming rules of the Huaxia fighter may have guessed it after seeing the name just now? The "S" suffix in China's fighter naming system represents the meaning of "two-seater model"-and the need to specifically mark this "S" in the model naming necessarily means that this type of fighter also has A single-seater version!
This is a version specially developed according to Tan Zhenhua’s strong request. In this version, more radical improvements will be tested, such as boldly replacing it with an "active matrix liquid crystal display" plus an "electromechanical soft touch button" model. The traditional "cathode ray tube" type display plus "electromechanical switch".
This "active matrix liquid crystal display" is a technology obtained by Tan Zhenhua on a special trip to the country.
Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors (TFT). It mainly uses current to stimulate liquid crystal molecules to generate dots, lines, and surfaces to form a picture with the back light tube. IPS, TFT, and SLCD are all LCD Sub-category, by the British T﹒ P﹒ Brody first produced the first display screen in 1973 and soon replaced the light-emitting diode in the field of electronic calculators.
The Japanese people began to invest in this field on a large scale in the 1980s. In 1987, Sharp successfully developed a 92160-pixel TFT LCD screen with the highest level in the industry, and hence the name "Sharp of LCD".
Compared with traditional CRT displays, liquid crystal displays have light weight, low power consumption, low heat generation, strong safety and environmental adaptability, good resistance to high-energy radiation and lightning, simple manufacturing and assembly, easy maintenance, and larger effective display area. The series quickly gained the favor of the aviation industry. In the United States, in 1987, the LCD screen made by Sharp was adopted by Collins as a component of the data transmission display and installed on Boeing 757, 727 and A320 models. Boeing also started the development of the 777 in 1990. This type of display was used on a large scale on mainline airliners; Lockheed also used this type of display on the YF-22 test flight in 1987. The YF-22 is the so-called "Advanced Tactical Fighter ATF" mentioned earlier. "The plan, and the final result of its development is the famous stealth fighter F-22.
Of course, such an important technology has also received the attention of Huaxia. Therefore, under the leadership of the Ministry of Industry and Information Technology, just this year, Huaxia established the "National Flat Panel Display Technology Research Project Team" to accumulate more than ten years of experience in this field. Ningdu Institute of Electronic Devices" is the core unit, organizing the participation of the Changchun Institute of Solid State Physics of the Huaxia Academy of Sciences and many top universities in China to strive for technological breakthroughs.
(The above two paragraphs are all historical events, the author's note).
In another time and space, the "National Flat Panel Display Technology Research Team" failed to achieve any substantial scientific research results due to weak foundations, lack of funds, patent barriers, foreign technology embargoes, etc., and Huaxia has made breakthroughs in the key to LCD displays. The field needs to wait until 2003 after BOE acquired the Hyundai TFT-LCD business of Nan Korea, which was on the verge of bankruptcy, but in this time and space, Tan Er said that he had to put his efforts in this regard.
This is naturally because liquid crystal is also one of the important industries he knows in the future. On the other hand, of course, it is because of the code name of the "Ningdu Institute of Electronic Devices", the core unit of the "National Flat Panel Display Technology Research Group". It was called 4055, which was the work unit of his mother Xu Yun.
