The world's military development, large high-speed aircraft have the ability to quickly deliver, is impossible to have traditional troops, on the ground, the army is easily blocked by preparation, many encirclement points can be successful, the blocking line is very important, even if there is a huge disparity in troops, in a specific place to preset the battlefield, it is also easy to resist the attack of others, not to mention the will and combat effectiveness of the troops are very good. Just like the current World War I, trench warfare has changed the situation of war, defense is easier to take advantage of than attack, and the balance of power that has been formed, in addition to fearless sacrifices, I am afraid that only new equipment can solve it.

The emergence of tanks and armored vehicles can solve trench warfare, but in the era of large-scale use and frontal battlefields, and even to the popularization of tanks and blitzkriegs, trench warfare and blocking lines still have the soil for survival, but this role has been weakened a lot, and in the later World War II period, trench warfare existed, but in terms of importance, it could not be compared with World War I.

The emergence of large transport planes in a concentrated manner was in the later Cold War period, both sides needed a weapon that broke the conventional method of warfare, its appearance changed the basic practice of land warfare, the battlefield is no longer the plane of the ground, it has the dimension of the air, and has become three-dimensional, under the premise of no air supremacy, the air force can not only strike at any ground target, but also can flexibly project troops on the battlefield, as long as the range of the aircraft is reached, air supremacy is possessed, and even partial air supremacy, troops can be invested in any weak part. Even with the growing tonnage of transport aircraft, even real main battle tanks can be projected.

This completely changed the course of the war, at any time, the resistance and defense of the frontal battlefield are the most powerful, the flanks and the rear are the weakest, a powerful force that can be compared with the ordinary attacking force, and even the main force, suddenly appeared in the rear of a front, bringing pressure and destructive power, absolutely breaking the balance.

China has always given priority to the development of the air force, and if there is no accident in the future, the air superiority will be obvious, and it will be easy to gain the initiative on the battlefield, but the air force is not the army, and it was not until the eighties and nineties of the 20 th century, during the Kosovo War, that there was a war dominated by the air force, and before that, even the Gulf War in 1990 was only entered after the air force gained superiority.

In the future, China is definitely a mechanized corps operation, which requires high-power transport aircraft, in a short period of time, it can be deployed on the largest scale, and under the premise that time is not too important, it mainly relies on ships, but at a critical moment, only aircraft can complete 1000 kilometers, or even 2000 kilometers of rapid delivery, which is the most fundamental way to give full play to the effect of large transport aircraft.

Whether it is the needs of the war, or China itself, it needs this kind of large long-range transport aircraft, the reason is very simple, the future of China's territory is too huge, the original 11 million square kilometers of land, with Baotou as the center, is only about 3500 kilometers away from the borders, but with the addition of the entire Siberia, Southeast Asia, and even Australia, such a huge territory, there may be a super empire of 30 million square kilometers, in that case, even from the core area of China itself, The distance to any place will be more than 3,000 kilometers, or even 4,000 kilometers.

The core area of the mainland, even just won Siberia, because of the direct border with the mainland, can be replaced by rail, although the railway is a little slower than the plane, as long as the railway network is laid, the speed of about 180 kilometers, not afraid of any weather conditions, can be projected around the clock, a little slower than the plane, but acceptable, but not abroad, the Indochina Peninsula borders, as long as the effort is completed, the railway can also achieve rapid projection ability, but the whole of Southeast Asia and Australia is not goodIf you use a ship, even if it is a high-speed transport ship, you can't guarantee a speed of 500 kilometers per day, which is too far from the railway limit of 4,000 kilometers.

Airdrop and air transportation, this has been proven countless times, the reason why the United States can become the world's police, is because of the global delivery capability, bombers taking off from the United States mainland, can bomb any corner of the whole world, and long-range transport planes, in a day's time, can send tens of thousands of fully armed, and even have enough strategic and tactical weapons to any disputed place on the earth, and it is also thanks to this that the ********, the huge territory, It will not be attacked by the enemy to find a weak link, and it will also make the huge empire that has never been in this world truly stable.

It is precisely because of the insight of later generations that the northwest under the guidance of Yang Yuanzhao, and even later China, from the very beginning, have gone to the right path, the convenient railways popularized in the country, the continuous expansion of merchant ships, the maritime shipping routes, the most critical aircraft, among all the core, is the most important, can quickly achieve the task of troop deployment, which is very beneficial to the country's security, and even in the future, outward expansion.

As early as 1913, the prototype has been established, under the intervention of Yang Yuanzhao, some achievements have been made, but the prototype has not completely solved the core problem, the problem of the engine, 4 high-power engines, representing the highest level of technology in the whole of China, 4000 horsepower engines, 4 combined, not even comparable to the power of an engine in later generations, which is also the fundamental reason why this large transport aircraft can not increase the tonnage of transport, in the future, with the progress of aero engines, will gradually expand to 6,000, or even 10,000, in this case, this large long-range transport aircraft can finally take shape, take-off weight will exceed 100 tons, becoming a real giant.

At this time, the prototype is in the 17th round of testing, through the previous tests, has basically solved some problems, but the control system, and even the overall layout have problems, temporarily unable to achieve the best degree, is rapidly improving, is expected to be about 2 years, can solve most of the basic sub-projects, and finally reach a more perfect state.

Yinshan base, Yang Yuanzhao has stopped government affairs, worked here for 15 days, the high-power engine work, has been carried out for more than 9 months, only the last step, to complete the engine horsepower from 4000 horsepower to 5500 horsepower jump, the increase of 1500 horsepower, in front of the 4 engine, equal to the power increased by at least more than one-third, but the total tonnage has not increased much, the load will be on the basis of the original, increase by half, Reaching an astonishing figure of 50 tons, this tonnage, can definitely produce phased results.

However, there is a key problem now, the engine running time has been increased from 3 hours to 36 hours, but there is still a big gap with the initial 1500 hours, not to mention Yang Yuanzhao's final requirements, the limit of 9000 to 10,000 hours, this limit is very critical for the engine, long-range transport aircraft is different from fighters, once he flies, it is a long-term flight, 10 hours, or even a few days of continuity, it is normal, there is not enough life, and his effect can not be exerted to the extreme.

It is precisely because of the poor progress, so I asked Yang Yuanzhao here, after Yang Yuanzhao arrived, the first time, put a final prototype engine into the all-in-one machine, this is the biggest shortcut, in reality, a lot of things, can only pass the step-by-step test, such as the engine, must go through a long time to start the test, even destructive start-up, to see the reliability and duration, in the all-in-one machine, as long as the scanning function is scanned, you can know the specific data.

Under the sweep of this engine, the ultimate power can reach 5780 horsepower, and it is no problem to exceed 5500 smoothly, but the spindle is a little worse, the hardness is enough, the toughness is not enough, the heat resistance is not enough, it should be the spindle material selection is not good, as well as the combustion chamber, and many other aspects, even the turbofan has some problems.

These problems are not too big, but when they are gathered together, they have formed a problem that the engine cannot last, and after reading the items that need to be solved, Yang Yuanzhao has the bottom in his heart, and began to give drastic orders, and soon, a new experimental project was divided.

The person in charge of the large aircraft engine project looked at Yang Yuanzhao with admiration, although Yang Yuanzhao is currently in charge of the huge China, but in the field of power, he is still the most powerful in the whole of China, he has not found the problem so hard, Yang Yuanzhao just came to see a few times, and found it.

In the field of engines, that's it, sometimes, no matter how hard he tries, he can't find where the problem is, he has combed back and forth dozens of times, without any clue, the underground staff, and without any gains, before asking Yang Yuanzhao for help, originally just wanted to shirk responsibility, because in his opinion, Yang Yuanzhao is in a hurry, should not be able to spare time to come, but he didn't expect that Yang Yuanzhao came, and after he came, he solved his key problem.

Not only found the problem, but also gave a solution, for example, he is now doing the experiment, using RBA435 metal, instead of the original spindle, re-production of the spindle, although this metal has just been included in the metal catalog, but can be processed, at least, it is no problem to produce less in the laboratory, which also means that the solution to the problem has appeared.
