Chapter 824

Some people may think that the 18.2 tons of aviation fuel output is not much. At best, it can only refuel six J-8 II or three Su-27s.

But this number has already satisfied quite a number of people in the air force.

We need to know that the aviation fuel carrying capacity of hohhot-6 is as much as 37 tons, but the output capacity is only 18.5 tons, and the range is only about 5500 km, and the operational radius is only a little more than 1500 km of Su-27, which is 1800 km.

This index is not a short leg for a special aircraft, which aims to provide air support and logistics support for combat aircraft. It almost becomes a burden.

On the other hand, oil-15 is developed on the basis of yun-15max, with a full range of 7200 km and an operational radius of 3000 km, which can fully meet the development needs of the air force in the next decade.

After all, the air force is actively expanding the scale of the Su-27 series of heavy fighters. In addition to the J-10 fighter, which is about to complete development and is ready to enter the intensive flight test stage, the number of three generations of fighters in China will usher in explosive growth in the future.

Under such circumstances, the combat radius is only more than that of fighter planes, and it is obviously difficult for a lost tanker to meet the actual needs of the air force's attack defense integration in the future.

What's more, yunyou-15 has more advantages than hongyou-6 in comprehensive cost.

Yes, although Hongyou 6 is based on the mature Hongyou 6, the overall operating cost is much higher than that of the new yunyou-15.

It's not supposed to happen. After all, hong-6 has been working in Northwest Airlines for nearly 30 years since it imitated the tu-16 bomber in the 1960s. It can not be said that it can grind an iron pestle into a needle, but it should also consume things carefully. At least it should be familiar with all aspects.

As a matter of fact, Northwest Airlines is really not familiar with this aspect. They are not familiar with every part of H6. Even many teachers who close their eyes to touch the parts can accurately tell the tolerance of the difference. They have done it for most of their lives.

If not, the air force would not have been willing to bombard yau-6 in the first place, in order to make this power multiplier, which can be said to be able to hit the fist further, completely independent, so as not to be controlled by others at a critical time.

As a result, the air force was surprised from top to bottom when compared with the hyo-15. The performance of hyo-15 was good or bad, but in terms of manufacturing cost, the new hyo-15 was nearly 20% lower than the mature hyo-6.

We need to know that there are many manufacturing technologies used in Hongyou 6, and almost 60% of the parts above can be interchanged. Except that the base of yunyou-15 is yun15plus, the rest is almost new from the inside to the outside, and the top and bottom are all widened and enlarged. Not to mention, even the engines are increased from two to four.

It can be said that from the inside to the outside, all of them have been changed. It's a new model.

It is reasonable to say that the purchase cost of Hongyou 6 with mature technology should be lower than that of the brand-new yunyou-15. As a result, the two are just the opposite.

The leader of the air force was very puzzled, so he went to Tengfei group and Northwest Airlines factory on the spot. He didn't know. He was really surprised.

I thought the scale of the two aviation enterprises was almost the same, and their strength should not be separated. However, when I looked at them on the spot, I found that the concepts, technologies and processes of the two enterprises were almost the same.

More than 60% of the mature technology and production process of H6 are used in Northwest Airlines, which really reduces the cost. However, the key to reducing the cost depends on who to compare with. Compared with traditional airlines, it is true, but compared with Tengfei group, it is not enough.

Because 95% of Tengfei group's production technology of yunyou-15 is the same as that of yun15.

What does that mean?

In the manufacturing process, Tengfei group can save 95% of the cost of fixture, mold, tolerance measurement, etc., and only need to invest a certain amount of money in the other 5% to solve all production problems.

Northwest Airlines can only use 60% of the existing fixtures, molds and tolerance measuring tools in the H6 production line, and the remaining 40% completely need to be remade. Due to the particularity of aerial refueling aircraft and the small number of aircraft in the air force, it is estimated that many specific molds and fixtures will be eliminated and scrapped when they are used up.

It is precisely these things that occupy a large number of production costs in the production of Hongyou 6.

In contrast, Tengfei group does not need to consider these. Although there are some differences, Tengfei group will try its best to apply these specific fixtures, molds and tolerance measuring tools to the production and processing of other models, and it will continue to glow.

This is the aircraft flexible manufacturing technology that Tengfei group began to study and gradually applied to aviation production in the mid-1980s.

At the beginning, when Tengfei group applied this manufacturing technology, although it caused a sensation in the industry, it did not get a wide range of imitation. The reason is that the one-time investment of this manufacturing technology is too large.

Take the flexible fixture commonly used in the aircraft production line of Tengfei group as an example. This kind of fixture uses vacuum to absorb workpieces and can be adjusted automatically according to the shape of the parts. It costs 200000 yuan just for a small part the size of a shoe box.To make a traditional fixture, it may be less than 30000 yuan.

By comparison, other airlines boast that Tengfei group is indeed a pioneer in catching up with the technological trend in China, and then And then Then there's no more.

The airlines are not stupid. They only spend 200000 to solve problems that can be solved with 30000 yuan.

So in the mid-1980s, the products of other airlines were very competitive in terms of cost. After all, the technical cost of the production line of Tengfei group in that period was very high, which could not be reduced at all. Therefore, at that time, Tengfei group did not confront these airlines head-on, but looked for air raids that could not be covered by the major airlines, and did differentiated operation.

For example, UAV, Yun 6 small transport aircraft, Yun 15 series light transport aircraft, Yun 16 special modified aircraft, tm-9 small business aircraft, etc.

However, with the passage of time, the 30000 RMB molds of other aviation factories have been made batch after batch. Over the past few years, with the rise of materials and the fluctuation of currency exchange rate, the cost of production has not decreased. On the contrary, it has increased a lot compared with a few years ago.

After years of cost dilution, the 200000 yuan that Tengfei group smashed down with one hammer at that time was lower than the cost of the molds that other aviation factories spent 30000 yuan to manufacture.

With the increase and decrease of each other, the cost advantage of Tengfei group immediately appeared. Coupled with years of continuous research in flexible processing and pulsating production line, and consistent cost control, Tengfei group is no longer Wu Xia amung, but Guan Yu was still that Guan Yu.

Zhuang Jianye's eyes turned. What's the matter with Jingzhou?
