Take Off My Aviation Era

Because of this, regardless of the appearance of TNB-2E and TNB-2B, there are essential differences between the two UAVs in terms of materials, craftsmanship, avionics and performance.

Just like Jetta and Passat, although both are Volkswagen’s doll faces that have remained unchanged for years, in essence, the two models are not the same thing at all.

This is the difference between TNB-2E and TNB-2B.

Take the materials used in the two models as an example. TNB-2B uses the most common aviation aluminum alloy, and its source can be traced back to the aluminum alloy material used on the old J-6.

It's just that China's Ascendas' manufacturing capabilities for traditional aerospace aluminum alloys in sheet metal, bending, cutting, machining, etc. are far from the 1960s and 70s. Therefore, this type of traditional aerospace aluminum alloy can be made thinner and flatter. .

However, no matter how it is optimized, the essence of traditional aviation aluminum alloys will not change, that is, compared with today's lightweight modern high-end aviation materials, not only the overall weight is heavier, but the structural strength is also very general.

This has also led to the fact that the payload and range data of TNB-2B are not good-looking. In addition, the WD-41ML-200 turboprop engine is only an entry-level product of this series of engines, resulting in general performance. Like.

TNB-2E is different. The keel is made of high-strength aluminum-lithium alloy, part of the supporting structure and the fuselage skin are made of carbon fiber composite material, and the wings, horizontal tail and vertical tail are largely composited with aramid fiber honeycomb structure. Material.

These materials are not only expensive, but the equipment used to process them is also not cheap.

Take the tools on the most basic machining equipment.

If you want to process carbon fiber composite materials and aramid fiber honeycomb structure composite materials, the most basic configuration is the use of tools.

After all, the traditional tools used for metal machining are not suitable for the processing of composite materials, because composite materials are not only strong, but also easy to delamination and wire drawing due to their own characteristics.

Not only that, if the tool is not useful, it will also cause the processed material to deform, burn, and finally lead to complete scrap.

Therefore, composite material processing tools are a very critical basic element for the production of qualified composite material accessories.

In this regard, only Lockheed Martin of the United States and the take-off of China are in a monopoly position.

Yes, China Ascendas is not only a global leader in the production of composite materials, but also an invisible champion in the field of professional processing of composite materials.

Take, for example, special drilling tools for carbon fiber composite material processing.

Take it out alone, almost no difference from ordinary alloy knives. They are all cross-shaped rotating heads, spirally extending, exuding metallic luster, and there is nothing unique.

However, when you put it under a high-power microscope, you will find that the cutting edge on the carbon fiber composite tool is fundamentally different from the traditional knife. There are multiple cutting edges on the board, which are combined just like the combined knives in the front section of the shield machine. It is not a single cutting edge that is fighting, but the combination of cutting edges is charging in a group.

The advantage of this is that the hole processing can be completed in the shortest time while avoiding the formation of delamination and wire drawing to the greatest extent.

Of course, if you want to achieve this step, you can't just think about it. It needs extremely precise calculation and design to complete.

Without the rich experience in this field and the accumulation of technology in multiple batches of product iterations, it is impossible to even think about it.

This is not to mention, you must have the best industrial design software and ultra-precision processing equipment to complete it.

China's take-off is not talented, these two have long been available, let alone the JSNB series of industrial software itself is China's killer in industrial design, only ultra-precision processing, China's Ascendas additive processing technology (that is, 3D printing technology) It is unique in the world.

Relying on these two trump cards, China Ascendas has created its own unique tool system for composite material processing based on ceramic matrix composite materials.

After years of development, it can completely compete with the related brands of Lockheed Martin in the United States.

However, whether it is Lockheed Martin or Take-off, related products are expensive.

Therefore, the use of props by other manufacturers depends on their specific processes and products.

After all, Lockheed Martin's products have a longer lifespan, but the corresponding cost is also higher; Takeoff's lifespan is slightly worse, but the cost is lower.

It can be said that each has its own shortcomings and each has its own strengths. Because of this, many manufacturers that require composite material processing are basically a mixture of the two.

Of course, Saudi Arabia's TNB-2E UAV production line doesn't have to be so troublesome. All domestic equipment is used. Naturally, the knives have to use Chinese Ascendas products. Otherwise, I think that 20 billion US dollars can be paid?

That would be too silly and naive.

It is necessary to know that an ordinary T300 carbon fiber composite drill bit produced by China Tengfei will cost 20,000 US dollars.

The service life of this cutter head is only 450 holes.

That is, after 450 holes were drilled, the $20,000 special tool was completely scrapped. If you want to continue to use it, you can only change to another $20,000 tool of the same model.

There are 11,800 precision holes on each wing of the TNB-2E UAV, and there are no less than 1.2 million connecting holes in the entire aircraft.

And 75% of the whole machine adopts composite material structure, 75% of 1.2 million is 900,000, 450 holes need to be replaced with a special tool, think about 900,000 empty, 2000 tools are needed, and each tool is 2 Calculated in 10,000 U.S. dollars, 2,000 copies are 40 million U.S. dollars.

This is only the tool consumption of a TNB-2E UAV.

The key is that Saudi Arabia is struggling with Bala. UU Reading www.uukanshu.com struggled with the drone production line that almost tore his face with the current old king. How could it be possible to produce one?

At least 100 racks are required, otherwise how to demonstrate Prince Salman's magnificent decision.

The consumption of these 100 UAV light tools alone is 4 billion U.S. dollars.

The problem is that the similar consumables in the entire production line are not just such special tools, such as the regular upgrade of industrial control software, the regular maintenance of machine tools, the consumption of auxiliary materials, and the use of basic raw materials...

The miscellaneous things together are the bulk of the profit of the production line.

In other words, once this TNB-2E UAV production landed in Saudi Arabia, it would be tantamount to a leech lying on the Saudi body. It would never let go of its mouth without absorbing the blood in the Saudi bone marrow.

Otherwise, Zhuang Jianye would do this business regardless of the predecessors?

You must know that aircraft production lines that are banned in developed countries are generally unavailable for money. How can Zhuang Heixin stop if he doesn't make a doubling?
