Siheyuan starts from a good life

"Comrade Jiang Yan, I take the liberty of disturbing you." After sitting down, General Engineer Lu spoke first.

"No need to disturb you. Mr. Lu can come. It's not too late for me to be happy!" Jiang Yan said immediately.

"I came to you this time to talk about your views on the aircraft you envisioned. To be honest, I am currently in charge of the design of a new aircraft, and your ideas about the new aircraft are somewhat inconsistent with mine. Together, it’s even a lot more advanced.”

Hearing Mr. Lu's words, Jiang Yan did not answer, but pretended to listen carefully.

Jiang Yan is standing on the shoulders of giants. Otherwise, according to his own background, he is nothing compared to Mr. Lu and Mr. Xu. However, he knows his own background, and those who follow them professionally cannot compare. , in order not to miss out later, I have been crazily making up lessons in the past two months. Fortunately, this is an aircraft factory, and my level is high enough. All the information is almost non-confidential to me, and I don’t have room for a computer. With the existence of cheating devices, his knowledge of aviation has also made rapid progress. Although there is no way to compare with these powerful experts, he is still quite capable compared to those ordinary researchers. Don't forget, Jiang Yan came from the information explosion. At that time, coupled with the perspective of these decades, the experience was much better than theirs, so Jiang Yan was not afraid at all when guiding them.

However, Jiang Yan also knew that in such a large country, he was full of iron and could hammer a few nails, and he only provided guidance. The subsequent research and development would still be done by these professional people.

"I also thought about my previous thoughts about the aircraft." After Jiang Yan said this, he continued: "The first is a reasonable nose design. Only with a wide field of view at the nose can the pilot have a larger forward field of view. , the enemy aircraft can be found faster and more accurately during the dogfight. I think it is more appropriate to measure the air intake, so that the nose of the aircraft can be left with space to install radar and various electronic equipment. "

"You guys, take a look at this airplane." After Jiang Yan said this, he picked up a piece of paper and drew a rather weird airplane drawing on it. The air inlet of the airplane is still at the nose of the airplane, but at the air inlet The top of the plane is still the nose of the plane, as if there is a big mouth under the nose of the plane, which makes this drawing look weird.

"Both of them are experts in the design of aircraft. They are no strangers to a certain aircraft that we imitated from the Mao Xiong. This aircraft uses a nose inlet. The advantage of the nose inlet is that it can be used in various flying postures. It ensures smooth air intake, is less likely to inhale debris when taking off and landing, increases speed faster, and is relatively simple to maintain.

"However, its shortcomings are also obvious. The main disadvantage is that it is a serious waste of space and it is difficult to arrange the cockpit and nose radar. Moreover, if it is used on a larger aircraft, the air intake will be too long and the air intake efficiency will be affected. Influence."

"However, our country's scientific research capabilities are now limited and cannot be improved on a large scale, so I thought that the aircraft I saw before was the Eagle F-8 fighter jet, which was manufactured by Chance Watt Company of Eagle. A carrier-based supersonic fighter developed by the Navy. Design began in May 1953, originally numbered F5U. The prototype flew for the first time in March 8, and was delivered to the Eagle Navy for use in March 1955."

"You see, the air inlet of this aircraft is a semicircular row of air inlets under the chin. To be honest, the arrangement of the air inlet of this aircraft is a compromise, which not only ensures the air intake efficiency, but also facilitates installation. Radar and other electronic equipment.”

Seeing the design plan of this aircraft, Mr. Lu and Mr. Xu's eyes lit up, and they looked thoughtful.

"As far as I know, Mr. Lu's Wuye aircraft uses side air intake. I have to say that this is a bold attempt by Mr. Lu, and it also provides new ideas for the development of our country's aircraft. Its advantages The aerodynamic layout is simpler than the former, and the process requirements are relatively low. It can also ensure the air flow for the engine to operate normally under large angles of attack. The height of the inlet is higher than the former, making it more suitable for takeoff and landing on simple runways and field airports. However, it has shortcomings. Under the condition of large deflection angle, the air intake on one side cannot suck in enough air, which greatly reduces the air flow required for the normal operation of the engine and easily causes mid-air parking. I think it is precisely because of this that Mr. Lu uses dual engines. "

Regarding the advantages and disadvantages of side air intake, Jiang Yan spoke clearly and clearly, and Mr. Lu couldn't help but nod.

Before they could ask questions, Jiang Yan then said, if the aircraft uses a transonic area rate wasp-waisted fuselage to reduce transonic drag and ensure that the aircraft flies smoothly in the transonic zone without violent rotation, it will be conducive to low-altitude sonic sprints. A larger horizontal tail hip should also be used to increase the tail capacity, which can improve the longitudinal stability of the aircraft. A dual-chamber booster is used to increase the horizontal tail rotation angular speed and improve the aircraft's following performance.

The space axis method can be used to rotate the front wheel forward 87 degrees and store it under the cockpit floor. This can maintain the appropriate ratio of the load of the front wheel and the main wheel, so that the aircraft does not jump when taxiing quickly, and can enhance the attack on ground targets. Ability, design as many hanging points as possible inside and outside the fuselage and under the wings, so that it can carry various bombs, rockets and other weapons... "

Under Jiang Yan's guidance, Chief Engineer Lu also drew some related brief drawings, such as the improved design drawing of the wing pylon, the improved drawing of the landing gear, etc. The three of them became more and more excited as they talked. Under Yan's guidance, a large number of designs were designed by several people. Jiang Yan's office also became the research and development room of these people. A large number of drawings were drawn. The most shameless thing about Jiang Yan is that the original war in history The double delta wings of the -7 aircraft were also mentioned smoothly.

The final result was that General Engineer Lu proposed that for their Fifth Master project, a special design room could be established at Jiang Yan's research institute. For this special design room, Jiang Yan could serve as the honorary researcher of the research institute. director.

Jiang Yan's special design office is not under the direct leadership of the project department or research institute. Instead, it assists General Engineer Lu and his colleagues in solving project problems. In this way, Jiang Yan can go to Jiang Yan at any time without delaying his other tasks. Discuss the problems they encountered on their projects.

However, he may be needed as the chief designer of the project, who often flies between the two places. However, the transport aircraft of the era are not so comfortable to sit on, but as long as it is fast, it will be fine! In order to create a better Fifth Master, we aviation people can overcome any difficulties!

However, whether this studio can be set up still needs to be reported to the higher authorities.

Regarding this, Jiang Yan felt that it didn't matter anyway, "This is for driving one sheep, and for herding two sheep. You can also herd three or four together!" As long as it doesn't delay his work, Jiang Yan still has quite a bit of time. Be willing to give.

Seeing how happy Jiang Yan was, Mr. Lu also said that the benefits should be provided. The old landlords and their wealth in the old days could not use people in vain, but they still need to go back to have a meeting to study the benefits.

Regarding this, Jiang Yan said that it really didn't matter whether it was true or not.
