The most important raw material of the aircraft is aluminum, of course, the original aircraft is wood, this kind of aircraft as a researcher, the aircraft of enthusiasts is OK, wood is easy to find, and easy to process, the rigidity performance is not bad, in the aircraft has not entered the country's sight, maybe a designer relying on wooden machine tools, can produce aircraft.

However, this kind of aircraft has poor protection ability, there is no way to resist the bullets on the battlefield, and the aircraft that really has combat effectiveness is a metal aircraft, although at the beginning some people also proposed to use steel, but with the specific gravity of steel, it is almost impossible to fly into the sky with all the planes made of steel, which is too high for the engine requirements.

Light metals, light specific gravity, easy to process and not easy to oxidize combustion, that is, a few, compared to the other materials are expensive, aluminum naturally stands out from the raw materials. In addition to aluminum, China has also creatively used other materials, and has made a lot of innovations in strategic aircraft, and the new materials that were opened in the fifties and sixties of the 20th century were used by China in advance in strategic bombers, and in places that can reduce weight, a large number of carbon fiber, polymer composite materials, and the specific gravity of polymer composite materials are much lower than ordinary wood, and some materials, in a single aspect of performance, are much higher than ordinary metal materials, used in other aspects, maybe a little extravagant, but when used in airplanes, it is a perfect match.

The most important thing is that these other countries have not studied, even if they occasionally study the expensive materials, produced in China, the price is not expensive, the strategic aircraft is more than 10,000 large-scale aircraft, each of which is very large, in this case, it is impossible to produce all by the all-in-one machine, so in the selection of materials, to avoid the current level of science and technology in China can not produce materials, the selection of processing is not high, and the performance is relatively outstanding materials.

The price of polymer composite materials, many are not expensive, but the research is not in place, the price is expensive, and aluminum was once regarded as a precious metal, the price is more expensive than gold, the reason is that the amount of aluminum is scarce, the processing technology is not enough, when the technology of electrolytic aluminum is completed, aluminum has become a cheaper metal than steel.

Polymer composite materials, to put it bluntly, is the carbon element as the main polymer as a whole, this polymer in nature is very little, or even will not be produced, but through industrial processing, they are produced, as long as the process problem is solved, in fact, his own cost is quite low, but carbon and oxygen in the whole world, the content is quite high, and it is more convenient to obtain raw materials, this raw material is more just the cost of the process, of course, China will not choose difficult to process, difficult to produce, after solving the process problemUnder the premise of industrialized mass production, the price is lower and the cost is relatively low, and under the premise of solving the process problem, it is at most more expensive than raw materials, but much cheaper than metals of the same quality.

Of course, it is only the price of China's military procurement, on the market, it is still on par with the world, but there is a certain amount of subsidies to prevent foreign countries from importing aluminum from China on a large scale, affecting the basic price of the entire aluminum, and ensuring consumption.

Most of the composite materials are only about half of the aluminum, and the most important thing is that about one-third of the composite materials are used, which are almost half lighter in weight than all metal and aluminum, and the overall weight is at least one-sixth less than all metal, which is at least two or three tons of weight for a strategic bomber with an empty weight of more than ten tons.

Two or three tons, for a battleship, is nothing, even if it is the smallest gunboat of several hundred tons, two or three tons is only a slight adjustment, but for the aircraft, this is too critical, the weight not only determines the flight altitude of the aircraft, flight speed, and even the range of fuel consumption and many other aspects, all have something to do with it, even if it is the same specification, the reduction of 2 tons, can also make the performance of the aircraft, up a huge grade, not to mention that these materials have their own roles, Some of the materials will make the aircraft have unique properties in terms of sinking resistance and many aspects, and some of these properties can directly change the performance of the aircraft, even if each part of the aircraft changes very slightly, on the whole, the performance of the strategic bomber is satisfactory.

In all aspects have achieved the ultimate, so that China's strategic aircraft has a very outstanding performance, in the price, quite an advantage, the price is always the most important aspect of a weapon, World War II, the Soviet T34 and the German Tiger, on the performance alone, T34 is not comprehensive, simply strengthened protection and firepower, in other aspects, not the opponent of the Tiger, but a simple manufacturing, low price in this aspect, it is enough to make the T34 overwhelm the Tiger, become the most outstanding tank during the entire World War II.

The same example is AK47, although there are countless world-famous guns in the same era, their individual performance, far more than AK47, but in the world, AK47 has become the first choice of most of the world's non-government forces, and even in the war, there are examples of throwing away the standard weapons of the government army and picking up AK, on the one hand, AK reliability is very strong, in most extreme cases, can be used, on the other hand, AK is cheap enough.

A very powerful, but extremely expensive weapon, only suitable for research use, not suitable for large-scale equipment troops, just like the Soviet Union made the world tremble T64 and T72, the former appeared earlier than the latter, but in terms of combat effectiveness, T64 is much higher than T72, almost T72 is a simplified version of T64, but because of the price, large-scale production, has become the largest selling Soviet tank after T34.

The same is true of strategic bombers, according to China's plan, the scale of production is unusually large, which has to put forward quite high requirements for the price, in the research and transformation, in addition to performance, the most important indicator is the price, and even for the sake of price, sacrificing some degree of performance, has reached the cost advantage.

Take the same performance as him, but also the world's first long-range strategic aircraft, the price of the U.S. B29 in World War II, even if the number of production exceeds 8,000 under the premise that the final cost is as high as 630,000 US dollars, this price, even if the U.S. military with deep pockets, it is impossible to have a large number of equipment, close to 8,000 aircraft, which has been misappropriated by many parties, and even some of them were produced after World War II, especially the huge investment in the Pacific War, to compete with Japan for air supremacy and sea supremacy, You have to have such an aircraft.

In the B29 just put into the Pacific Theater, he is like a bug as unsolvable, in many cases, Japanese fighter pilots, can only use their own planes, knock it down, but with the deepening of the battle, more and more fighter pilots, began to be familiar with B29, and even a Japanese ace pilot, has a record of shooting down 26, in the war, there are still 714 shot down, more than 3000 pilots missing, However, the B29 still changed the situation of the entire Pacific Pacific, and the large-scale bombing of the presence of the B29 played a great role.

Compared with B29, China's strategic bomber performance is more excellent, faster than B29, the flight altitude is about 1200 meters higher, the most important thing is the range, B29's range, about 2800 kilometers, but the use of turboprop Chinese aircraft, the range is at least twice as high as B29, reaching 5200 kilometers, which also represents the deterrence of this aircraft is greatly strengthened.

More than 20 years in advance, he has such a big killer, but his price is not expensive and unacceptable, at present, the purchase price of the Chinese Air Force, The ex-factory price of this aircraft is 125,000 Chinese dollars, although at present, at the time of the war, the currency between China and the United States cannot be deposited and exchanged, but generally speaking, the international recognition is still a dollar for 2 Chinese dollars, although the Chinese dollar has a faint upward trend, with China's continuous victories in the world, the Chinese dollar has also begun to go to the world, at the beginning it was only the allies, after all, they are all relying on China in logistics, it is impossible to get rid of China's finance, as for other countries, it is through the purchase and recognition of China's currency and reserves, even the enemy countries of the United States and Britain also have reserves, they are more, is to buy Chinese medicines and some supplies, but not on the surface, but on the black market.

China belongs to the Allied Powers, and there is no direct connection between the Allies and the Entente, but Britain and the United States need Chinese medicines, other things, high-consumption things, can be tightened, but there is no way to save lives like medicines, and they have to buy whatever they want, and the Chinese dollar has stronger purchasing power than the dollar.

Such a powerful, much more powerful aircraft than the strategic bombers of the U.S. Army in World War II, It is only equivalent to 62,500 US dollars, this price is very cheap, pure industrial manufactured products, a ton is less than 1,000 US dollars, even if the dollar is quite expensive, the price is very low compared to the golden age, plus China's revenue conditions, far stronger than the world's strongest, just a silk stockings and medicines combined, it is enough for China to harvest 30 billion to 50 billion dollars of funds every year, in this case, China's production of strategic bombers, is more than 10 times that of the US military in World War II, this is an extremely terrible number, according to a strategic bomber, can carry about 45 tons of bombs, 80,000 is enough to carry 3.6 million tons of explosives at a time, even if it is just a conventional bomb, it is very scary.
