Some people think that 18.2 tons of aviation fuel output is not much, at best it can only refuel 6 J-8 II. or 3 Su-27s.

However, this value has already made a considerable part of the Air Force very satisfied.

You must know that the aviation fuel carrying capacity of the H-6 has reached 37 tons, but the amount that can be output is only 18.5 tons, and the range is only about 5,500 kilometers, and the combat radius is only slightly more than the 1,500 kilometers of the Su-27, which is 1,800 kilometers.

This indicator is no longer short legs for a special aircraft designed to provide air support and logistics support for combat aircraft, and it is almost a burden.

On the other hand, the Y-15 developed on the basis of the Y-15 MAX has a maximum range of 7,200 km and a combat radius of 3,000 km, which can fully meet the development needs of the Air Force in the next 10 years.

After all, the Air Force is actively expanding the scale of the Su-27 series of heavy fighters, coupled with the J-10 fighter that is about to complete its development and is ready to enter the intensive test flight stage, the number of domestic third-generation fighters will usher in explosive growth in the future.

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

What's more, the transport \ oil-15 also has more advantages than the bombing oil 6 in terms of comprehensive cost.

Yes, don't look at the fact that the H-6 is based on the mature H-6, but after careful calculation, the overall comprehensive operating cost is much higher than that of the brand-new Y-15.

It stands to reason that this situation should not occur, after all, the H-6 has been groping for nearly 30 years at the Northwest Aviation Plant since the imitation of the Tu-16 bomber in the 60s.

In fact, the Northwest Aviation Plant really has nothing to say in this regard, and every part of the H-6 is not familiar with it, and even many masters who touch the parts with their eyes closed can accurately say what the tolerance of the difference is.

If it weren't for that, the Air Force wouldn't have been able to start with the bombardment, in order to make this force multiplier, which can be called a fist that can hit farther, completely independent, so as not to be controlled by others at a critical time.

As a result, the Air Force was taken aback from top to bottom by comparing the H-6 with the Y-15, and the performance was still good or bad, but in terms of manufacturing costs, the brand-new Y-15 was nearly 20 percent lower than the mature Y-6.

You must know that the H-6 uses a lot of H-6 manufacturing technology processing technology, almost 60% of the parts on it can be interchanged, and the transport \ oil-15 in addition to the base is the Yun 15plus, the rest from the inside to the outside is almost new, up and down all widened and enlarged, not to mention, even the engine has increased from two to four.

It can be said that it has been changed from the inside to the outside, and it is a proper new model.

It stands to reason that the purchase cost of the bombing 6, which follows the mature technology, should be lower than that of the brand-new transportation \ oil-15, but the result is just the opposite.

The leaders of the Air Force were very puzzled, so they visited the Tengfei Group and the Northwest Aviation Plant on the spot.

I thought that the two aviation companies were about the same size and their strength should be indistinguishable, but at a glance on the spot, I found that the concepts of the two, the technologies used, the applied processes, and the configurations adopted were simply one in the sky and one underground.

The Northwest Aviation Plant's H-6 adopts more than 60% of the H-6 mature technology and production process, which does reduce costs, but the key to this cost reduction depends on who to compare with, and compared with traditional aviation plants, it is true, but it is not enough to compare with Tengfei Group.

Because of the technology of Tengfei Group's production of Yun\Oil-15, 95% of the production process of Yun-15 is followed.

What does this mean?

Tengfei Group can save 95% of the cost of fixtures, molds, tolerance measurement and other aspects in the manufacturing process, and only need to invest a certain amount of money in the other 5% to solve all production problems.

The Northwest Aviation Plant can only use 60% of the existing fixtures, molds, and tolerance measurement tools on the H-6 production line, and the remaining 40% completely need to be remade.

It is precisely these things that occupy a large amount of production costs in the production of Bomb Oil 6.

On the other hand, Tengfei Group does not need to consider these at all, although there are differences, but Tengfei Group will try its best to apply these specific fixtures, molds, and tolerance measurement tools to the production and processing of other models, so that they can continue to shine.

This is the flexible manufacturing technology of aircraft that Ascendas Group has been researching and gradually applying to aviation production since the mid-80s.

At the beginning, when Tengfei Group applied this manufacturing technology, although it caused a sensation in the industry, it was not widely imitated, for no other reason, it was really too much one-time investment in this manufacturing technology.

Take the flexible fixture commonly equipped with Tengfei Group's aircraft production line, which uses vacuum to absorb the workpiece and can be automatically adjusted according to the shape of the part, and the clamp for a small part the size of a shoe box alone costs 200,000 yuan.

And to make a traditional tooling fixture may not even be 30,000 yuan.

In such a comparison, other aviation factories except boast that Tengfei Group is indeed a pioneer in catching up with the technological trend in China, and then ...... And then...... There is no then.

The aviation factories are not stupid, and they can solve the problem with 30,000 yuan, but they only spend 200,000 yuan to do it after their heads are pumped.

Therefore, in the mid-80s, the products of other aviation factories were still very competitive in cost, after all, the technical cost of the production line of Tengfei Group in that period was particularly large, and it could not be reduced at all, so Tengfei Group at that time did not encounter these aviation factories head-on, but looked for air raids that could not be covered by major aviation factories to do differentiated operations.

For example, UAVs, Y-6 small transport aircraft, Y-15 series light transport aircraft, Y-16 special modified aircraft, TM-9 small business jets, etc.

However, with the passage of time, the 30,000 yuan molds of other aviation factories are made batch after batch, and over the past few years, with the rise of materials and the fluctuation of currency exchange rates, the production cost has not fallen, but has risen a lot compared with a few years ago.

The 200,000 yuan that Tengfei Group smashed with a hammer that year, after years of cost dilution, has already been lower than the cost of molds made by other aviation factories for 30,000 yuan.

Coupled with years of continuous research on flexible processing and pulsating production lines, as well as consistent cost control, Tengfei Group is no longer Wuxia Ameng, but Guan Yu was still the same Guan Yu back then.

Zhuang Jianye looked at this, his eyes rolled, what did he do when he didn't kill Jingzhou to grab land?
