After Wang Guorui began to build an airplane, this airplane could be mass-produced, and even the red alert system he wanted could be mass-produced. However, it was of no use, because the plane was easy to build, but the pilots could not make it in large quantities, and those who could be qualified flight instructors could not make it in large quantities. Because the pilots are all officers, this own red alert system can't produce clones who can play with airplanes, so this still has to be cultivated by itself. And the conditions for training pilots are too high, and with the stupid appearance of those clones, it is impossible to say that they are competent for the use of aircraft or even command air battles in the future.

"Your Majesty, the biggest weakness of our current aircraft is also in terms of materials. We are currently desperately short of lightweight metal, and if we can use aluminum, we can avoid using this wood for aircraft. Even if we can use a layer of alloy skin, so that we can make the aircraft more protected. This made it possible to avoid enemy bullet strikes, the maximum possible protection of the pilot. We also know how difficult it is to train pilots, so we need to protect them as much as possible. And the pilot is easily hit by a large number of enemy rifles on the ground if he is in the air later, so a metal base plate for us is also a must. At the very least, it is necessary to be able to resist the enemy's bullets, even if not completely, and to be able to avoid those bullets from penetrating the inside as much as possible, so as to cushion the power of the bullets. Death of a pilot is more heart-wrenching than losing a plane in the future! Said the officer with the equipment department.

At present, this pilot is actually the same test pilots at that time, and although those test pilots can already fly airplanes, the price spent on these test pilots is already very high for other units. Cultivating a pilot is almost the same weight as their body, and in this day and age, the propeller plane does not have to be so high, but it is not too low. Therefore, a pilot is definitely much more expensive than an airplane, and this is inevitable in any era. Moreover, airplanes can be produced quickly through assembly lines, but it takes at least ten years to grow a pilot from small to large. So no matter what, the pilot will be much more expensive than the plane, especially in the war, it is the consumption of the pilot, not the consumption of the aircraft, it is better to lose the plane than to lose the pilot.

"With armor, will our planes still be able to fly?" Wang Guorui tried to ask.

The technician of the armament department replied: "There is no way, we can only install armor on the reconnaissance aircraft at present, and it must be lightweight metal armor." At present, we can only try to use aluminum to make armor, but aluminum armor is obviously not hard enough, so we will try to use this aluminum alloy to make armor. However, we have not been effective. At the moment, we can only make this armor very thin, not completely able to keep the rifle bullets out, only to slow down the power of the rifle arrogance, and then prevent them from penetrating too deep. ”

"If we use iron armor, it is too heavy, and even if we have two aircraft engines, we can't move it. Moreover, in accordance with the technical requirements, the twin-engine engine is adopted, which can protect the life of the pilot as much as possible. However, the iron armor is too heavy, if the iron armor is installed, the twin engines may be able to fly, but once one of the engines has an accident, then in the end, I am afraid that only one engine can not be effectively loaded, so it is actually the same as a single engine. Our current engines are not yet able to carry too heavy armor, and this is the biggest problem. ”

"So since we can't make rapid progress in the engine in a short period of time, we can only study light alloy, but this light alloy may be too light to have enough hardness. However, if it is too hard, it is often heavier and cannot be driven by the engine. This is what we are embarrassed about, and we can only let the Materials Research Institute be responsible. ”

Wang Guorui also closed his eyes, even before he crossed back then, he knew that airplanes were the highest embodiment of a country's industry. An airplane represents the most concentrated place of a country's industry, don't look at only one airplane, but it concentrates on engine technology, various power technologies, and even all kinds of machinery manufacturing, as well as all kinds of mechanics and so on, almost every aspect of the industry is also involved. Even this materials science is involved, and this materials science is the most important.

Wang Guorui even read online novels in later generations, and a great god of industrial flow once wrote that in later generations China can actually make many things. But the material is not up to par, and the material is not up to par, which makes it very difficult for them. This material is not up to par, so that China's fifth-generation fighter jets have been unable to be mass-produced, and even if they do, they will not be worth the loss.

"The material is not up to standard?" Wang Guorui asked again.

The technician replied: "Your Majesty, yes, it's not the materials." Whether it is the alloy of the engine or the aircraft skin, there can be no qualified materials. We need to be all kinds of lightweight alloy materials, and they must be hard enough, otherwise we can make the aircraft achieve better performance and defense. And all kinds of alloys are the means by which we currently solve various needs. And the research and development of this alloy is actually a matter of materials science. And there are almost no shortcuts to this material science. Materials science can only be tested one by one, and then the corresponding parameters can be tested. And these materials have a variety of special effects, some are very hard, some are soft enough. However, high hardness is not necessarily the best, high hardness may be more brittle, and the yield is obviously not good. And the same is true of artillery, too hard alloys are not suitable as artillery barrels, because this kind of barrel either does not explode, but once it explodes, it is irreversible, because this cannon is too hard and does not have a little flexibility and yield, it is also easy to explode. ”

"And we have to carry out the same analysis of all kinds of alloy materials, even alloy and non-alloy materials, and all kinds of metal and non-metal materials, otherwise we will not be able to effectively manufacture various materials and aircraft. There are no shortcuts to materials research, and there are hardly many rules to follow. Even if it is mechanical manufacturing, it can still have mechanics and various references, but this material science is the most difficult, and there are almost no shortcuts to take, so we have no good way at present, and we can only conduct the same material test here. ”

The material determines the development of the aircraft, and the aircraft needs to be a light alloy, and it must have enough hardness and resistance to high temperatures, and even the ability to withstand high temperatures. Rockets are also one of the most important, and the most important ability is to make rockets that must not only resist high temperatures, but also withstand high temperatures.

There are almost no shortcuts to the material, only the same "trial and error", and only the possibility of all the errors can be experienced once, so that the trial and error can be truly tested. This is too difficult, the investment is too large, and there are many basic materials that are insufficient. This has put a bottleneck in the development of aircraft, and if there is no suitable material in a short period of time, it will definitely be difficult to develop rapidly.

"Materials science only relies on the accumulation of time, but what we lack most at present is time. My Red Alert system can produce most of the products, but what's the use? Even I was able to get the drawings, but they were useless. The material that is produced, but I can't get the material and the process. And drawings are one thing, and being able to turn drawings into reality is the ability. Even if I could get the agents to steal the most advanced shipbuilding technology from the British, I could even get the blueprints. But this is useless, even if I steal the drawings, it can only be produced in this red alarm system, but in reality, it is impossible to produce it by myself natural person workers. It's so hard! This material, maybe the same chemical element, but after a different heat treatment process, it is a completely different effect. Most of these heat treatment methods will inevitably be hidden and will not be announced at all. ”

"Some materials may only be physically treated, and there are tens of thousands of methods of heat treatment in later generations, so it is impossible to judge carefully. In ancient times, horse urine was even used as a way of heat treatment, what a fool, these materials are dead! Where do we have time to try and make mistakes slowly, if we continue to try and make mistakes slowly, then I am afraid that there will be no more than ten years of no effect, which is really tricky. ”

However, at this time, someone immediately came.

"Your Majesty, the British are here, and they want to come over to discuss what kind of technology we want in China. According to the previous agreement, they have selected some technologies from those technology lists, and then exchanged them for our Chinese market. The British and Germans are here, what technology do we want, this emperor, you want to see if you accept their request? Jun Ji-hyun asked.

After Wang Guorui heard this, he immediately laughed and said: "This time is really interesting, what we lack, they also sent something, so we can't slaughter them well, then we are really sorry for this good opportunity!" Since they have sent it to the door, then we will not be afraid of anything, how can we do it without slaughtering fat pigs? When they beg us, we want to see how we come to kill the three soldiers again! They simply don't dare to refuse, because they need our Chinese market. (To be continued.) )
