The Japanese military department, recognizing the huge role of aviation in the war, has already planned to develop its own jet combat aircraft. The Japanese have realized that compared with China's combat aircraft, Japan's combat aircraft have many shortcomings, and not only are they much slower than China's main fighters, but they are also far inferior in terms of airframe structure. Of course, the reason for this situation is, on the one hand, due to the Japanese fighter design ideas, and on the other hand, due to the lack of Japanese resources, especially aviation materials, so the design and use of aircraft, tanks, combat vehicles and even rifles have been greatly affected.

The combat planes and tanks equipped by the Japanese army are all thin-skinned guys, even if it is a new fighter such as the 96 land attack, it also has the characteristics of a lighter, and it will burn as soon as it hits, there is no way, who makes the Japanese lack resources, and it is precisely in this way that the Japanese Empire embarked on the road of foreign expansion.

Historically, Japan's aviation industry was founded in 1910. In 1931, there were less than 400 aircraft produced annually. In 1941, it produced 4,800 aircraft per year, and in 1944, it reached an annual output of more than 28,000 aircraft and 40,000 engines. During World War II, Japan's aviation industry ranked fifth in the world after the United States, the Soviet Union, Germany, and the United Kingdom. In this time and space, everything has changed, and now the Japanese are beginning to design and manufacture their own combat aircraft with the advanced aircraft and technology provided by Germany, after all, it is very difficult and economical to buy them completely from Germany, and at the same time it is subject to others.

A month ago, the Japanese military department issued a tender for a new generation of jet fighters and bombers, requiring major aircraft manufacturing companies to design schemes in accordance with the requirements of the tender and hold a bidding meeting in mid-December.

On December 15, a large conference room of the Japanese military headquarters was lively. Representatives from six aircraft manufacturing companies, including Nakajima Aircraft Corporation, Mitsubishi Corporation, Aichi Corporation, Kawanishi Corporation, Tachikawa Corporation, and Kawasaki Heavy Industries, brought their own proud works to win the next-generation jet fighter project.

The Japanese military department in the tender for a new generation of jet fighters is very high, this fighter is required to be used on land and sea. Because the Admiralty has planned to name the new generation of jet carrier-based fighters as Type II ship warfare, which means that whichever company gets the final project contract will have to carry out serial design of this jet fighter, and through relatively small changes, make the Navy's Type II ship warfare, as well as the army fighter.

The tender called for the fighter to weigh no more than 6 tons. However, the bomb load is required to reach 1.2 tons, the range should reach 1,500 kilometers, the cruising speed should be greater than 650 kilometers per hour, the maximum level flight speed should be greater than 750 kilometers per hour, the maximum dive speed should be greater than 800 kilometers per hour, the maximum rate of climb at sea level should be greater than 50 meters per second, the height of climbing to 10,000 meters should not exceed 5 minutes, and the maximum ceiling should reach 13,000 meters, and the dynamic ceiling should reach 14,000 meters. The stall speed is not more than 200 kilometers per hour, and the endurance time is more than 3 hours. The Japanese military department wants to treat the new generation of jet fighters as multi-purpose aircraft, not only to have strong air combat capabilities, but even to have the ability to bomb aircraft, this 1.2 tons of bomb load, for a fighter with a maximum weight of no more than 6 tons, is almost an incompleteable design.

First up was Japan's Mitsubishi Heavy Industries Aircraft Company, a long-established aircraft manufacturer. On behalf of Mitsubishi Aircraft Corporation, the demonstration of the scheme is still the chief designer Jiro Tunnel. Looking at the audience, the principal officials of the Admiralty and the War Department, who had never dealt with each other, sat together. Jiro was also wondering in his heart, haven't the two always been at odds. Why did the tender for the new fighter come together this time, and could it be said that there will be changes in the Japanese military circles in the future? However, at this time, he could not think too much, and successfully obtaining the contract for the new generation jet fighter project was his main task.

A month earlier, Jiro Kiruki had also attended the Admiralty Department, where the newly appointed Minister of the Navy, Shigetaro Shimada, was chairing a military meeting and discussing the development of a new generation of naval fighters. At the time, he was at odds with Nakajima's Koyama, and this time Jiro was ready to prove that he was right with a victory.

The preparation of the excavation is still very sufficient, not only the detailed drawings of the aircraft of the design plan. Scaled-down models of two navy and army fighters were also prepared, and the military officials in the audience nodded frequently, and they seemed to be quite satisfied.

Jiro sorted out his thoughts for a moment and said loudly: "Our new generation of jet fighter adopts nose air intake, and a jet engine with a maximum thrust of 2,000 kg is installed in the tail of the fuselage. Above the fuselage is a blister-shaped cockpit. Piloted fighter for a single person. The airflow in flight is divided into left and right strands in the nose of the aircraft by a partition in the air intake. The wings are located in the middle of the fuselage in front of the fuselage, with straight trapezoidal wings with 4 wing knives, and two auxiliary fuel tanks or bombs can be hung under the wings. The wing penetrates the fuselage and, in conjunction with the partitions inside the intake tract, divides the intake airflow into four strands. At the same time, a certain amount of lead is placed in the leading edge of the wing to reduce the requirements of the wing for torsional rigidity. At the same time, in order to avoid the influence of tail jet flow and high temperature, the flat tail is designed in the middle of the vertical tail, so that the efficiency of the flat tail will be higher, and the maneuverability of the aircraft will be further improved. ”

"Why don't we adopt the mainstream aerodynamic layout of the current fighter? This is due to the fact that the aerodynamic layout of the current fighter has a large windward area, high drag, poor maneuverability at high speeds, and in the case of limited engine thrust, the speed potential of such a jet fighter is not large. Our jet fighter program army type length of 9.8 meters, wingspan of 10 meters, height of 3.2 meters, wing area of 18.8 square meters, empty weight of 3350 kg, maximum take-off weight of 5900 kg, fuel load of 2000 kg, can ensure that the aircraft range of more than 1800 kilometers, at the same time, after the external auxiliary fuel tank, can reach about 2200 kilometers. If the fuel load is reduced to 1,200 kilograms, 1,200 kilograms of bombs can be mounted, and of course, the range will be reduced to about 800 kilometers, which can be used for close air support missions. "Digging Erlang said confidently.

"Our navy has undergone major changes to meet the needs of the ship. The wing area of the Navy scheme was increased to 27 square meters, and the wingspan was also increased to 12 meters, which ensured that the aircraft had a large lift and was able to achieve short take-off and landing on an aircraft carrier. The empty weight increased to 3800 kg, the maximum take-off weight was 5800 kg, and the maximum fuel on board was 1700 kg. In order to save valuable space on the aircraft carrier, there is a folding mechanism in the wing on the outside of the main landing gear, and the wingspan of the wing is reduced to 6.5 meters after folding. The wing is equipped with ailerons and split flaps, which are mounted in two parts in the fixed and folding sections of the wing. There is no lifting device installed on the leading edge of the wing, and trim tabs are installed on all pneumatic control surfaces. Of course, our solution also uses a lot of new designs, such as the front three-point landing gear and so on. Jiro introduced carefully. (To be continued.) )
