Regarding the restrictions imposed by the United States on the Haitang Kingdom, Li Guang was actually a little confused. You must know that it is a world war, and it is not good for the United States to weaken the power of its allies. President Roosevelt was on the move? No, the president of a big country should not be so unwise.

After in-depth thinking, Li Guang thought he had found the answer.

There is a complex called the blood complex, and this kind of thing is not even measured in terms of interests. The Chinese have such a complex, and the Americans also have it. Don't look at the official propaganda in Europe and the United States, there is not much racial discrimination. But at the deepest level of the heart, the Caucasians regard the Oriental peoples as inferior. In the eyes of Europeans and Americans, the yellow race may be inferior to the same class as blacks, not to mention the Americans' clamoring for democracy and freedom, and even giving blacks citizenship and the right to vote in the Constitution. But here's the thing: black people in America didn't have the right to vote in World War II. The fact that Americans see the British and Europeans as their own kind is still deeply ingrained even in the twenty-first century.

Li Guang speculated that Roosevelt's contempt for the Chinese caused the United States to discriminate against China and Haitang.

On the other hand, the United States may tolerate an emerging country with a strong army, but it will be very taboo to add another country with a strong navy to the world. A country with a strong navy will pose a threat to the global hegemony of the United States after the war.

Regardless of whether this is the reason or not, Li Guang has to integrate the military industry again.

The first item is battery production. Increase investment and improve the production line. So far, the battery is still the most profitable project in Haitangguo. Even in the future, it will be an industry that can be regarded as a pillar. Therefore, the research and development of batteries should also be strengthened, and strive to reach the modern level as soon as possible.

The second item. R&D for the production of torpedoes and dexterity bombs. One is to create benefits, and the other is to enhance combat effectiveness. Among them, the main direction of torpedo research and development is guided torpedoes, but there is still no breakthrough in guidance methods. The dexterity bomb, which continues to continue the idea of playing video games, is mainly developing in the direction of television guidance. To this end, Haitang has acquired a small television research institute. In the near future, it will all be transferred to Madagascar.

The third item is the R&D and manufacturing of radar. Although this item is unlikely to see economic benefits, it is the core of the Naval Resistance Force's efforts to improve its combat effectiveness. The first result of the radar R&D group. Now that they have begun to be installed, there is no doubt that the radio detector will be of great use on the battlefield.

Fourth, the development and production of anti-aircraft artillery shells. Haitang has recently made a breakthrough in technology: the successful development of the fuse of anti-aircraft artillery shells.

If readers and friends still remember, in the one hundred and eight chapters of this book, the Maritime Resistance Army recruited more than 60 high-end talents at that time. But if you leave all these people on Statue Island. Li Guang believes that on the contrary, they cannot play their role. Therefore, dozens of the most high-end talents were sent back to the United States by Li Guang. Several research directions have been set. and give it a grant.

After three years of painstaking research, the antiaircraft artillery fuze research group has finally seen results. Breakthroughs have been made in anti-aircraft artillery proximity fuses and variable-time control fuzes.

In the United States, there were no conditions to test in a real state, so the scholars followed the merchant ship to Madagascar and returned home.

In naval battles, the consumption of anti-aircraft artillery shells was extremely terrifying. In battle, if you want to take out a fighter. Ideally, about two thousand shells are needed. And it may not be able to completely intercept enemy aircraft.

What is the concept of two thousand shells? The cost of shells plus barrels is definitely more than 100,000 dollars, which is more expensive than an airplane. If we can't improve the hit rate, air defense alone can exhaust the naval resistance forces.

There are two main breakthroughs in the fuse of anti-aircraft artillery shells. The first is a proximity fuse that uses an induction coil. Second, it is possible to detonate a bomb by emitting radio waves through an electron tube. Later, this research went deeper and was integrated with the radar function, which was detonated using radar ranging feedback.

A few Chinese engineers worked hard to achieve this result at a cost of less than $100,000 in research funds. Later, Li Guang learned that the $100,000 he provided was not enough at all, and the engineers sold their property and devoted all of them to research. At the most critical moment for the country and the nation, everyone is doing their best.

Li Guang was extremely satisfied with the development of such an achievement at the cost of killing an enemy plane alone.

Now, these technologies only need to be verified for practicability and can be put into production immediately. It is estimated that it will be effective in three or two months.

This technology not only reduces consumption, but also improves defense capabilities. It can also reduce the bomb load of the ship. It is a well-known fact that no matter what warship, the more bombs it has, the more dangerous it is.

The fifth item is the research and development of rocket engines.

Due to the restrictions imposed by the United States on the export of high-tech products, it is obvious that it is impossible for Haitang to build a complete set of industries, especially since it does not have the ability to manufacture aircraft and other weapons. Missiles are also an important item in the research and development projects set by Li Guang at the beginning, and although there has been no breakthrough yet, they have also touched the edge of missiles and achieved some results. The application of missile technology in the naval resistance force, the first step was slightly off track, and this technology was first used on fighter planes.

In order to compensate for the performance shortcomings of the fighters, the engineers of the missile research group and the aircraft design group came up with a way to add rocket engines to the fighters.

It's a bizarre idea, it's science fiction. Li Guang does not know if there has ever been such an aircraft in the world, propeller plus rocket boost. However, a group of professionals are very sure that it is feasible, and anyway, this does not conflict with the direction of Li Guang's demand for the development of missiles. So the project was decided.

Li Guang knew that the Germans had developed jet aircraft in World War II. But it was not known that the Germans were already using one of the rocket-engined aircraft - ME163. Although it has not yet appeared on the battlefield, it has been successfully developed.

The ME163 fighter of the Germans was towed to a high altitude using a propeller aircraft, and then turned on the rocket engine and entered the flight state. The Naval Resistance Force, on the other hand, is slightly different, but only adds a rocket engine to a propeller aircraft as an auxiliary thrust. In terms of difficulty, the plan of the Naval Resistance Force is even simpler.

Rocket engines are also a high-tech product in the 21st century, but if the requirements are lowered. Although rocket engines are still difficult, they are not very difficult. According to Li Guang's requirements, its difficulty is not as difficult as a car engine.

The requirements are as follows: the equipment plus fuel, limited to a total weight of 100 kilograms, is required to be able to provide five minutes of thrust, and according to the calculation, the thrust should be more than 100 kilograms. It is equivalent to adding an additional engine of about 250 hp to the fighter.

You must know that whether it is a P40 Tomahawk or an F4F Wildcat fighter, they are both fighters weighing more than three tons. It has 1,200 horsepower, plus 250 horsepower. That's 1,450 horsepower.

Although the total power is not enough to catch up with the F6F Hellcat and F4U fighters that the US military will equip, the climb rate is beyond the reach of these two fighters when the weight is almost half light.

Of course, the thrust is as big as possible. If the material is difficult to reuse, it does not matter if you change the combustion chamber and nozzles at one time.

The reason why it is so demanding. It is because of the fighters that the Naval Resistance Army can get, whether it is P40 or F4F, can only add more than 100 kilograms of weight.

If these two fighters are compared with the Zero fighters of the Japanese army. In addition to low-altitude maneuverability is far inferior. Another serious problem is that the speed and climb speed are not as good as those of the Zero.

According to the tactics that the pilots of the Naval Resistance Army are most familiar with, hit and run. In fact, it does not pay attention to low-altitude maneuverability, but pays more attention to disengagement speed and climb rate.

The speed of detachment means that you can avoid fighting with the Japanese Zero fighters. A quick climb will allow you to regain your vantage point and give you a chance to launch the next round of attacks.

According to the calculations of engineers and technicians, as long as it can provide a thrust of 100 kilograms in five minutes. The P40 and F4F are capable of easily reaching a level flight speed of 700 km/h. That's pretty much the ultimate speed of a propeller aircraft. Breaking away from the pursuit of Japanese fighters was definitely not a problem.

On the other hand, the calculation of the rate of climb. It takes about nine minutes for F4F to climb to an altitude of 6,000 meters. The Japanese Zero took only seven minutes. It was such a two-minute gap that determined that the dive attack tactics of the Naval Resistance Army could not be used in turn. If the rocket engine can provide the fighter with five minutes of additional thrust, then the performance of the fighter will easily exceed that of the Japanese Zero.

To sum up: if the rocket engine can have a life of five minutes. It is completely possible to increase the fighter plane's chance to get out and seize a favorable position. In other words, just like playing a game, the pilot has one more chance to resurrect with full blood.

In the fight between life and life, this is already a great chance of winning. If this is done, even the backward P40 fighters and F4F fighters will greatly improve their combat effectiveness.

As for the specific installation problem, it will not be difficult, the design of fighters in this era is far from the sophistication of later generations, the degree of filling is not high, and if the rocket engine parts are designed separately, it is easy to add them to the fighter.

Of course, Li Guang's fundamental purpose will not change: The purpose of rocket engines is not only for fighter planes, but also for smart bombs or missiles.

Many people take it for granted that rocket engines are very complex. But in fact, the principle of rocket engines is no longer a secret in this era, much simpler than jet engines. Especially after lowering the requirements, it is really not difficult to design. The difficulty is the material for the manufacture of rocket engines, materials that are resistant to high temperatures and pressures, and parts that are resistant to high temperatures and pressures.

It's just that Li Guang, a traverser, is not proficient in anything, but he knows a lot of things. Among the high-temperature resistant rocket irrigation materials, he knows a material used in modern fighters - silicon carbide. Just such a little knowledge reduces the amount of labor that experts have to do for countless miles.

At present, Li Guang has several great scientists in his hands who will be famous in later generations, Huang Yushan is an expert in aircraft, and Qian Dana is a missile expert in later generations. It shouldn't be a problem for two people to work together to build a rocket of this calibre.

Another thing that advanced this cause was that the destroyer Qinchao captured by the Naval Resistance Forces in Ceylon had several Japanese spear oxygen torpedoes. The little devil has quite a unique way of using liquid oxygen. Rocket engines also use kerosene and liquid oxygen. Therefore, the Devil's oxygen torpedo provides a lot of useful reference for the rocket engine of the Maritime Resistance Army in terms of storage, pipelines, control, etc. So that the rocket engine on the road to practicality has taken many detours.

The sixth, naturally, is the highest-ranked classified project - Plan A. Now the project has been transferred to Madagascar, and Yuan Chou is still in full charge.

The importance of these six projects cannot be overstated. It will become a source of growth in the combat strength of the Naval Resistance Army. Of course, this can show the vision of a traverser. Li Guang has been in this era for many years, and has also developed for several years, all of which are products of copycat ancients, and Li Guang, a traverser, is too inferior.

And these six scientific research are called the six knives by Li Guang. When the six swords come out together, it will become the invincible "Mo Dao" array of the Haitang Kingdom. Invincible and invincible. (To be continued......)
