Chapter 1450: New plan (3)

The price Hitachi paid was the transfer of a first-generation LCD screen production line and the corresponding intellectual property authorization to "Huaxin Microelectronics", and "Huaxin Microelectronics" also got a ticket to enter the liquid crystal field.
Okay, Tan Er has collected "garbage" again...
It needs to be pointed out here that although Sharp is the leading company in liquid crystal technology in Japan and even in the world, there is not only one Sharp who has invested in this technology in Japan. In fact, many electronics and semiconductor-related companies in Japan have successively A large amount of investment has been made in this field. Before the development of the LCD industry in South Korea and China Bay Island, the entire LCD industry in the country was developing in clusters. There are many technical difficulties in this field and the future direction of technology development. It was also conquered and established under the investment and organization of the Ministry of International Trade and Industry of the Republic of Japan. From 1989 to 1993, the entire Japanese government, including the government and enterprises, invested US$4.4 billion in technology and production lines in the liquid crystal field, accounting for the global share of 85% of the total investment in the field, and therefore achieved a near-monopoly market position after the 1990s-in 1994, Waguo LCD products accounted for 95% of the global market share!
For Hitachi, the company is the Japanese LCD screen manufacturer second only to Sharp, and its TFT-LCD production line has also been iterated to the second generation. The glass substrate area has been upgraded from 300mm400mm in the first generation to 370mm. 470mm, so it is a very cost-effective business to sell the first-generation production line to Huaxin Microelectronics, and it is developing a brand-new technology, which also requires a large investment. This business is very effective in helping it withdraw. Funds.
By the way, the new technology that Hitachi is developing is the IPS that students are more familiar with. This kind of panel, commonly known as "hard screen", has changed the arrangement of electrodes on the upper and lower sides of the liquid crystal to a horizontal arrangement. When exposed to external pressure, the molecular structure The bottom is slightly sunken, but the overall molecules are still horizontal. When encountering external forces, the firmness and stability of the liquid crystal molecular structure of the hard screen is far better than that of the soft screen, so it will not produce picture distortion and affect the picture color, which can maximize Protect the picture effect from being damaged.
After reading this, you will know that Hitachi is indeed a leading company in the LCD industry. The IPS technology invented by it will be licensed to South Korea’s LG Electronics and Wandao’s Chi Mei Electronics in the future. It will also become Apple in a long time. Standard configuration for smartphones.
Although the first generation of TFT LCD screens are inferior to traditional cathode ray tube CRT screens in terms of display brightness and dynamic refresh rate, they have incomparable advantages in terms of power saving and weight saving. Therefore, when buying After the production line contract was negotiated, Tan Zhenhua also purchased some 9-inch LCD monitor kits from SKD. After assembly and shock-proof treatment, these kits will be installed on the single-seater version of "Flying Leopard B" for testing. , In order to further confirm whether it can become the standard configuration of this type of fighter, if feasible, it will be further promoted to the entire series.
In addition to the improvement of the display system, the single-seat version of "JH-7B" also has a large number of fully digital flight instruments that are still in the experimental stage. These instruments have higher integration and sensitivity, and the display and operation interface are more humane. The airborne fire control computer is also more powerful, and a complete set of flight control software compiled separately for it is also more complicated. The reason for this is that the operations that were originally performed by two aircrews now need to be performed separately. One of the pilots can do it independently. In order to reduce the pilot’s operating load to an acceptable range, a large number of automated controls must be added to maximize the pilot’s energy.
It should be understood that the "JH-7B" is different from the Su-27. It is a "war bomb" or "multi-mission" fighter. The missions to be performed in the future include air, ground, sea and other modes. Compared with pure For the Su-27 that dominates the air, there are six more working modes for the radar system alone. The weapon systems that may be mounted are also more complex and diverse. These require more effort from the pilots to deal with them. After changing to a single-seater version, It is equivalent to one person doing the work of the original two people, and if the automation level of the equipment is not improved, then there will probably be few people who can fly this type of fighter in the future.
Due to the reduction of one occupant, the length of the aircraft has been shortened, from the original 20 meters to the current 19.5 meters. In addition, a set of man-machine systems and instruments and many on-board electronic equipment have been eliminated due to the use of large-scale Compared with the previous generation, the single-seater version of "JH-7B" has reduced weight by more than 800 kg, and the empty weight of the whole machine has been reduced to less than 14 tons. The "Qinling" engine born out of the TF41 has a single thrust of 1.2 tons more than the standard "Speey MK202" on the original "JH-7", and the two engines are 2.4 tons more, which makes the "JH- The power of 7B" is more abundant, which also allows this type of fighter to bear larger external mounts-such a good condition can of course not be wasted. Therefore, the "JH-7B" has been upgraded from 7 to 11. There are 5 heavy-duty racks with a load capacity of more than 1 ton, and the external hanging capacity of the whole machine has reached 9 tons!
Well, this data actually makes the XAC plant quite embarrassed, because at this time, the latest modification of the "H-6" known as the "strategic bomber" produced by the XAC plant, "H-6F", has a maximum bomb load of 9. Tons, but that is a big guy with a body length of more than 34 meters and a wingspan of more than 32 meters...
Compared with the "JH-7BS", the "JH-7B" has more changes and adopts more new technologies. Therefore, the development progress of this type of fighter is much behind the "JH-7BS". According to Chen Yijian's estimation, The first flight will not be possible until 1993 at least, and the modification of another model will inevitably be later.
The last model of this "one aircraft, three types" was named "JH-7BH", which is a carrier-based aircraft model developed based on the "Flying Leopard".
It’s just that when this fighter first started its pre-research project, it was based on the two-seater prototype of the old
Flying Leopard
, but now it’s clear that it’s going to "two-seat co-development", and single/two-seater models will be promoted simultaneously. And the main force will be placed on the single-seater model.
It’s really not a simple matter to change a land-based fighter plane to a carrier-based aircraft. The upper deck of an aircraft carrier is just that big, and the runway conditions for take-off and landing are much worse than those on land. , Either by ejection, in short, a little help is needed; as for landing, it is even more difficult. Landing on an aircraft carrier is jokingly described as "controllable fall", and fighters are heavily "smashed." On the deck, in order to drag dozens of tons of fighter planes to stop, the aircraft carrier’s deck also needs to be laid with multiple blocking cables, which are forced to stop.
The impact of this fighter can be imagined.
So carrier-based aircraft need a much stronger structure than land-based fighters
Moreover, due to the limitation of the length of the aircraft carrier’s deck, fighters need to take off and land at a very short distance. They need better take-off and landing performance and low-altitude and low-speed flight capabilities than land-based fighters. To achieve this, it needs to be greatly increased. Generally speaking, the lift of a fighter plane is to increase the wing area.
The structure needs to be strengthened, the wing area needs to be increased, and it must be made foldable for boarding. The entire fighter plane, including the engine, needs to be treated with salt spray corrosion resistance. This is almost a new plane.
For China, it is too difficult to solve these issues independently without any experience accumulation, but fortunately, a genuine Mi Di carrier-based F14 "Panda" is parked in the Yanliang test flight base. There is also a senior carrier-based aircraft chief designer Lu Hesheng as the general counsel.
