Although the 1172 factory is not as well-known as the J-14, J-10, and J-11 producing factories in China, the income-generating ability of this factory is actually very strong.

Back then, during the surveying and mapping operation, the superior dispatched an An-12, which was surveyed and mapped by the factory itself, and it was built by itself without the help of the scientific research institute.

The JH VII, which was designed by 6603 and delivered to the 1172 factory for production, can be regarded as a product of the combination of the factory.

H6. Although this Han's main bomber already has a full set of design drawings and prototypes of the Tu-16 bomber, it was also relied on the research of the 1172 factory to finally complete the imitation.

Their scientific research capabilities are very strong.

Now, they have carried the scapegoat and have taken the charge of burning an electronic leopard. Although the senior management knows what is going on, after all, there must be a lot of discussion in the following meetings, and their face is not good.

Just a few words from Qin Guan, that can't make up for the damage to their souls, and of course they have to grab the project.

It is definitely not enough to introduce two anti-submarine anti-submarine aircraft. Now that the technical information has arrived at the same time, it is better to copy it by yourself!

As for the carrier aircraft, there are also ready-made ones, that is, Yunba!

Hearing what Director Wei said, Qin Guan also frowned secretly. He planned to use Yunshi for this project, but he never thought about it.

In other words, in the past few years, Qin Guan actually considered the issue of Yunba. After all, many domestic modifications in later generations were based on Yunba as the platform, but now, with the C-130 gradually entering the Han National Air Force Sequence, such a comparison, immediately found that Yunba has many shortcomings.

The Yun-8 is a comprehensive survey and mapping copy of the An-12, and the An-12 comes from the An-10 passenger aircraft of Xiongguo, which is incomparable with the specially developed C-130 transport aircraft.

Among them, the most important difference is the wing area.

The C-130 has a wing area of ​​160 square meters, and the Yun-8 prototype An-12 is only 130 square meters. Although the flight resistance is reduced, the aircraft's lift is insufficient, which leads to the low-speed capabilities of the An-12 and Yun-8. Poor, it's really like losing the watermelon and picking up sesame seeds.

The An-12 chooses such a small wing area, one is to save weight, the other is that the wing load is large, which is beneficial to flight stability in bad weather, and the third is to increase the speed a little.

However, this is definitely not worth the loss. The turboprop is originally not high in speed, and it is not the focus of the design. The short take-off and landing capability and flight stability can be enhanced in the future by upgrading the high-power engine. After the C-130J is replaced with a high-power engine, the slipstream of the propeller makes the transport aircraft almost impossible to enter a stall. The C-130 is also in the harsh climate of Antarctica. Can perform tasks well.

In contrast, the small area of ​​the wing and the larger aspect ratio also limit the external hanger capacity. In the entire design, the wing has always been dragged, and the internal space of the wing is insufficient. You must know that in the transport aircraft, the fuel is mainly It is placed in the wing. What's more, its cargo compartment is not pressurized. In the later stage, for example, the 8C was changed to air-tight type in order to enhance the survivability of the abdominal fuel tank, and the range dropped to 3,700 kilometers.

So, isn't it enough to 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 redesigning an aircraft.

In later generations, there were many modifications to the Yun 8 series, not because of how good the basic design was, but because of the inorganic availability.

As a patrol aircraft, the propeller is noisy, the slipstream **** and the fuselage is vibrated, and the crew is easy to fatigue. For example, the Holy Kingdom has reflected this problem with the ZDK-03 early warning aircraft. Therefore, the Eagle and the Xiong countries use more suitable single-wing P-3C and IL-38 modification.

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

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

In later generations, the next-generation Yun 30 model directly copied the C-130, and the designer's tendency to choose has become obvious.

It is precisely because of the backwardness of this engine that in Xiong, the An-12 transport aircraft is just a transition. Xiong soon started the development of a special Il-76 transport aircraft and became the main transport aircraft.

But in China, because of limited technology, it has always been repaired on Yunba. Even if it is called Yunjiu, it is just a change of Yunba.

Now, after hearing Director Wei talk about the issue of luck with enthusiasm, Qin Guan knew that this matter was eventually going to be done. Since Director Wei has proposed it, he should simply leave it to them.

"Everyone thinks, our Yunba or C-130, which one is more advanced?" Qin Guan said.

"Of course it's C-130." Someone said suddenly. It goes without saying that the advanced nature of C-130 is beyond doubt.

"Yes, since the C-130 is more advanced, how about our previous new project, surveying and mapping to imitate the C-130?" Hearing Qin Guan's words, everyone was stunned.

It would be better if you could copy the C-130 for surveying and mapping. It's a pity that now your own strength is limited. Can you complete the surveying and mapping for this kind of aircraft?

Everyone didn't have confidence. If they had confidence in the first place, they would just engage in C130, so why bother to imitate An-12?

After all, they are just a factory. How can the scientific research level of the factory compare with the design?

"Our air force has already equipped the C130, and we are full of praise for this aircraft. If we can map and imitate this aircraft, it will greatly improve the air force and navy's transportation capabilities and have great potential for modification, how about?" Qin Guan said, "If you don't have confidence, then you can leave it to other factories."

In China, each factory has its own expertise. In terms of large aircraft, it is the 1172 factory. However, there are other things now. The development of Yunshi is in Huating, Huating’s aircraft factory, which can also build large aircraft. If it doesn't take it, it might be given to Huating.

"Yes, we are confident that we will complete the surveying and mapping copying." Director Wei replied: "This will be our main task for a period of time in the future."

If this transport aircraft can be replicated successfully, it will definitely have great prospects. It is not only for personal use, but also for export. Anyway, the country’s technological level is developing rapidly, and it is not possible now. Maybe it will wait until the imitation is over. Has it broken through?

Director Wei agreed.

Qin nodded his point of view: "I will put forward this proposal to my superiors. If the superiors have limited funding, our North Industries Corporation can also inject funds to complete the research and development of new machines."

Now, North Industries Corporation is the most profitable company in the country, and it has enough capacity to support the development of various projects. Qin Guan believes that the Air Force and Navy will definitely be interested in this transport aircraft.
