After breaking through the sound barrier, rocket launchers can already be used in actual combat. China cannot allow rocket launchers to advance quickly like later missiles, using Mach 3 and Mach 5. That is the speed of high-speed defense-breaking missiles. Rocket launchers can only serve as cheap firepower at most, increasing rapidly from the initial speed 50-80 meters per second. On the premise of determining that it is relatively cheap, the maximum speed will not exceed 650 meters per second. Such a speed is already amazing enough.

For China at present, rocket launchers are just starting out and experimental rocket development has been basically completed. This is only the first step of the Long March. However, such weapons are basically impossible to use in war. Laboratory products are mainly for research needs and highlighting their power. Cost is the least necessary issue. However, under the premise of large-scale installation, cost is very important.

China's total economic output is extremely large. Even in terms of education and basic guarantees, it consumes too many resources, but the absolute amount of military expenditure is also quite large. However, China's military organization is huge, with the combined army, navy and air force exceeding tens of millions. If the price is too expensive, it is not enough to purchase on a large scale.

As for the current cost of rockets, China is rich and powerful, and it hurts to use. It is hundreds of times more expensive than shells. Compared with shells of the same caliber, the shells of the same caliber are not the highest-end 16-inch guns. Even if they look huge, they are only four times the price of this rocket launcher. However, the power of a 16-inch gun is much larger than that of a 207 or even a 307 rocket launcher.

This kind of disposable thing must be simplified, otherwise, even if it is powerful, there is no need to use it. This is just that the cost of the rocket itself has not calculated the huge investment in rocket research. If you include that, a rocket can be more expensive than a large-caliber shell. He can buy 50 shells of the same caliber, but a rocket launcher cannot complete the work done by 50 shells of the same caliber, so the price is a bit too expensive.

To simplify and reduce costs, first of all, from the material point of view, rocket launchers use aviation aluminum for all aspects, and add many precious metals as additives to increase ductility and durability. As a disposable weapon, one is used in every experiment. In order to obtain experimental data to the maximum extent and use the best materials, the best materials, the most accurate processing method can be used, and the most accurate processing method can be used. In this way, the cost of a single individual will be increased.

This is a common problem of general laboratory products. Fortunately, after large-scale production, it will be reduced to a considerable extent. China has a complete set of methods in terms of cost. Some experimental rifles and artillery are expensive. If they are really produced on a large scale, they will be reduced a lot, basically reaching the level of use. The same is true for rocket launchers. The previous encounter with sound barriers has caused a significant increase in the cost of rockets, mainly in terms of aerodynamics, increasing the speed and power of rockets. With Yang Yuanzhao's guidance, it is not difficult to achieve it. The aerodynamic structure has been made, and then it is modified based on this. In many cases, it is not necessary to achieve it without such high-end materials.

In the development of weapons, we have encountered this many times. Before breaking a certain boundary, we have to use the most cutting-edge materials to gradually overcome the difficulties. After really overcoming it, we will find that as long as we meet certain conditions and do not use particularly good materials, we can also produce effects. For example, for the MiG25 aircraft, this is a plane that specializes in dealing with the US high-altitude and high-speed reconnaissance aircraft. When it first appeared, it created many world records, which shocked a large number of military experts. Some even thought it was a smokescreen released by Russia.

However, in actual combat, Americans discovered that the MiG 25 is really so outstanding. He can follow the Blackbird high-altitude reconnaissance aircraft and warn or even shoot down easily. At high altitude, the maximum speed exceeds Mach 3. Such a speed cannot be achieved on most fighter jets. Before we figure out the true performance of the MiG 25, the United States and Britain were extremely panicked. They could not figure out what it was. It allowed the MiG 25 to have such a powerful speed, just like a sound barrier. A thermal barrier of Mach 2.5 will appear, which is a huge obstacle, and it is even more difficult to break through than a sound barrier. In history, only three aircraft have broken through this field, namely the MiG 25, MiG 31 and the American SR-71 Blackbird.

The blackbird is expensive, even the United States cannot bear it. More than 93% of the overall use of titanium alloy, and it is impossible to solve the problem of oil leakage. It keeps flying and leaking oil. At that time, Americans were very curious about how this aircraft was made of titanium alloy, and why there is no problem of oil leakage. The sr-71 can only be used for reconnaissance purposes, but MiG 25 can attack and raid at high altitudes, which made them puzzled.

Sometimes, the secret is broken one point. After a MiG 25 defected, the Americans finally figured out that the solution to this problem is so simple. Stainless steel is enough. MiG 25 is a large iron shell made of stainless steel, thermal barriers and sound barriers. There is no problem at all. It can fly at a speed of Mach 2.8 at an altitude of 24,000 meters, which is also due to this. However, in addition to high-altitude high-speed, the other performance is very poor and even radar cannot be installed. This defect quickly unveiled the mystery of MiG 25. MiG-25 fighter has its own advantages in many aspects, but in terms of overall performance, it is only equivalent to the American-4 "Ghost" fighter, which is not too threatening to the newly developed -15 "Eagle" fighter and the -16 "Fighting Falcon" combat agency that the United States developed at that time.

This is the terrible thing to break through a certain boundary. The same is true for rocket launchers. With the suggestion of Yang Yuanzhao, the aerodynamic structure of the entire rocket was solved with a better aerodynamic structure, and the aerodynamic structure of the entire rocket was also determined. The simplest aerodynamic structure was used to reduce the material of the rocket itself to the lowest, and use more cheap and easy-to-forge materials, such as steel with certain elements, cast iron, or ordinary aluminum alloys, and use less expensive materials, such as magnesium, lithium, copper and other metals, which will cause performance reduction. However, under the adjustment of aerodynamics, the performance reduction is proportional to the reduction of price, and can basically be invested in practical research.

From cheap to high prices, the price of this rocket was immediately highlighted, especially the small caliber. In one inference, it was even reduced to 3 times the price of a mortar shell of the same caliber. You should know that the weight of a rocket is generally more than 10 times that of a mortar shell, and the power of a rocket of the same caliber is much larger than that of a mortar shell. The gap between the two is even greater, which also increases the price of a rocket. To a certain extent, the performance of a small caliber rocket launcher exceeds that of a mortar and will become the object of flexible use by special forces.

Of course, Yang Yuanzhao knew very well that rocket launchers were cheap, but in the future field of rocket launchers, the most important thing was missiles, which represented the direction of the future. Missiles were never cheap. A truly high-performance missile was even higher than ordinary aircraft. The power of this kind of missile was huge and could greatly improve the performance of fighter jets.

Therefore, with the support of Yang Yuanzhao, after gradually reducing the price of rocket launchers, the rockets were divided into two different directions. One is of course to reduce the price and produce a very cheap weapon, and the other is to pay attention to accuracy and control performance. No reliable chip radar has been developed yet, but the direction is there, and using various kinetic energy without changing, controlling the trajectory of the rocket. Even a little change will make the final hit point completely different. This is the transformability and controllability of the rocket.

While determining the accuracy of the weakened rocket and reducing the cost of the rocket as much as possible, we also strengthen the research on precise weapons, especially the use of some vectors, such as some controls of rockets. We do not seek to be more accurate, but only seek to change. This is also a preparation for missiles after the emergence of rocket chips in the future.

In two directions, one is towards a larger range, more precise control, and even card handling progress. The third-stage rocket proposed by Yang Yuanzhao was quickly made and invested in the experiment. The range from 60 kilometers to 200 kilometers is very fast. Of course, the investment is also high. Once the rocket is launched at a range of 200 kilometers, one experiment is equivalent to more than 5 times the price of about 207 mm around 60 kilometers. With the increase in range of 200 kilometers, the price will rise wildly.

The biggest difference between rockets and other weapons is that rockets are disposable consumables. Regardless of whether the experiment is successful or not, this time the rocket will always consume. With the increase of the range of the rocket, the cost of the rocket has also increased significantly. In particular, the use of vector change engines can be used to fine-tune the rocket's operating attitude through certain controls, which is even more terrible for the increase in cost. The price of a 200-kilometer rocket is even more than 5 times that of a 60-kilometer rocket, which is almost as effective as a light aircraft. Such an equipment is not very effective. After all, the range is huge. The longer the range, the greater the proportion of fuel in the rocket, so there will be no combat position. The dozens of kilograms of things are not powerful compared to the huge range. This makes the researchers a little disappointed. (To be continued.)
