Super Weapon Swap System

Although plant 1172 is not as famous as the 1132 plant producing j-14, J-10 and J-11 in China, the income generating capacity of this plant is also very strong.

In those years, when surveying and mapping yunba, the superior dispatched an-12, which was mapped by the factory itself. Without the help of the scientific research institute, it was worked out by itself.

The j-h-7, which was designed by 6603 Institute and produced by 1172 factory, is a product of the combination of the factory.

Bomb 6, the main bomber in the Han Dynasty, although it already has a full set of design drawings and prototypes of tu-16 bomber, it is also a imitation completed by the research of plant 1172.

Their scientific research ability is very strong.

Now, they have taken the blame for burning an electronic leopard. Although the senior management knows what's going on, after all, there will be a lot of discussion below, and their face is not good-looking.

Just Qin Guan's words can't make up for the damage to their hearts. Of course, they have to grab the project.

It's absolutely not enough to introduce two fan hunting anti submarine aircraft. Since those technical materials have arrived at the same time, it's better to copy them by your own side!

As for the carrier, there are ready-made ones, that is, Yun Ba!

Hearing what director Wei said, Qin Guan also frowned secretly. He planned to use Yun 10 for this project, but he didn't want to go to Yun 8.

In other words, a few years ago, Qin Guan actually considered the problem of yun-8. After all, many modifications in later generations took yun-8 as the platform, but now, with the C-130 gradually entering the sequence of the Han air force, such a comparison immediately found that yun-8 has many shortcomings.

Yun-8 is a comprehensive mapping imitation of an-12, and an-12 comes from an-10 airliner of Xiong state, which can not be compared with the specially developed C-130 transport aircraft.

The most important difference is the wing area.

The wing area of C-130 is 160 square meters, and the prototype an-12 of yunba is only 130 square meters. Although the flight resistance is reduced, it leads to the lack of aircraft lift, resulting in the poor low-speed ability of an-12 and yunba. It can be said that we have lost watermelon and picked sesame.

An-12 chooses such a small wing area. First, it saves weight, second, the wing load is large, which is conducive to flight stability in bad weather, and third, it will increase speed.

However, this is definitely not worth the loss. Originally, the speed of turboprop conveyor is not high, and it is not the focus of design. The short takeoff and landing capability and flight stability can be strengthened by upgrading the high-power engine in the future. After the C-130J is replaced with the high-power engine, the slipstream of the propeller makes the transport aircraft almost unable to enter stall. The C-130 can also perform its mission well in the harsh climate of the Antarctic.

In contrast, the small wing area and the large aspect ratio also limit the plug-in capacity. In the whole design, the wing has been dragging its legs, and the internal space of the wing is insufficient. You know, in the transport aircraft, the oil is mainly placed in the wing, not to mention that its cargo tank is not pressurized, and in the later stage, For example, Yun 8C changed to air tight. In order to enhance its viability, it had to cancel the abdominal fuel tank, and the range dropped sharply to 3700 km.

So, don't you just redesign the wings?

Of course not. The wing is of great importance. If the wing is redesigned, the overall aerodynamic layout will change, and the workload is no less than that of redesigning an aircraft.

In later generations, there are many modifications of Yun 8 series, not because the basic design is good, but because inorganic materials are available.

As a patrol aircraft, the propeller noise is large, the slipstream slaps the fuselage and vibrates greatly, and the passengers are prone to fatigue. For example, holy state has reflected the problem of zdk-03 early warning aircraft, so Eagle state and bear state are refitted with more suitable lower single wing P-3C and il-38.

As a fuel dispenser, there is no external auxiliary fuel tank like C-130 to increase the fuel volume.

As a special aircraft, the low-speed maneuverability brought by small wing area is worse than that of C-130, which is not conducive to changing into gunboat aircraft and other models with high requirements for low altitude performance.

In later generations, the next generation of Yun 30 model directly copied C-130, and the designer's choice tendency has been obvious.

It is precisely because of the backwardness of this engine that an-12 transport aircraft is only a transition in xiongguo. Xiongguo soon started the research and development of special Il-76 transport aircraft and became the main transport aircraft.

However, in China, due to limited technology, it has always been repaired on yun-8. Even if it is called yun-9, it is only a modification of yun-8.

Now, after hearing Director Wei talking about yunba with great interest, Qin Guan knew that this matter was to be done in the end. Since Director Wei put it forward, let's just give it to them.

"People think, which is more advanced, yunba or C-130?" Qin Guan said.

"C-130., of course," someone said at once. It is also said that C-130's advanced nature is beyond doubt.

"Yes, since C-130 is more advanced, how about our last new project, surveying and mapping imitation of C-130?" everyone was stunned when they heard Qin Guan's words.

It would certainly be better if we could copy the C-130. Unfortunately, our own strength is limited. Can we complete the mapping and imitation of this aircraft?

People have no confidence. If they had confidence at the beginning, they would directly engage in C130. Why copy an-12?

After all, they are just a factory. How can the scientific research level of the factory be compared with that of the design institute?

"Our air force has been equipped with C130 and is full of praise for this aircraft. If we can map and imitate this aircraft, it will greatly improve the transportation capacity of the air force and Navy and have great potential for modification." Qin Guan said: "if you don't have confidence, you can hand it over to other factories."

In China, each factory has its own expertise. In terms of large aircraft, it is 1172 factory. However, there are other factories now. Yunshi's R & D is in Huating. Huating's aircraft factory can also build large aircraft. If your side does not bear it, it may give it to Huating.

"Yes, we are confident that we will complete the surveying and mapping imitation." factory director Wei replied: "this will be our main task for some time in the future."

If this transport plane can be copied successfully, it will certainly have great prospects. It can not only be used for its own use, but also be exported. Anyway, the country's scientific and technological level is developing rapidly, not now. Maybe it will have broken through when the imitation is over?

Director Wei agreed.

Qin Guan nodded: "I will put forward this proposal to the superior. If the superior's allocation is limited, our northern industrial company can also inject funds to complete the R & D of the new machine."

Now, Beifang Industrial Company is the most profitable company in China and has enough ability to support the development of various projects. Qin Guan believes that both the air force and the Navy will be interested in this kind of transport aircraft.
