Chapter 922

You should know that even according to the simplest flight test process of fighter, it needs three flight test processes before it can be finalized and put into active service.

The first flight test was an engineering flight. Under normal circumstances, a new fighter developed by the research and development unit according to the design ideas proposed by the military must first conduct the first flight verification after the manufacturer completes the production.

This is usually carried out on the runway of the manufacturing plant. Although the military participates, the test flight is mainly carried out in the factory base, which is used to verify the basic safety and operability of the aircraft and ensure that the aircraft can safely fly to the test base for type test flight alone.

In this first flight test, the fighter will be partially modified according to the problems found in the first flight and the military's opinions. The fighter plane will be repeatedly inspected through the test flight to expose and modify the design defects one by one, and then conduct the flight test again. This process is relatively long and the interval is long, but the final result will be a fighter with excellent aerodynamic performance.

Only after reaching the standard in all aspects, the fighter will rush to the special flight test research unit for type test test, which also means that a new type of fighter has entered the engineering development stage from the verification aircraft!

Of course, the current test flight application of infinite gravity group is not in this category, because first of all, all the four fighters are independently developed by the infinite gravity group, and are not designed according to the customized requirements of the military. This is developed by their company according to their own standards, but the relevant interface standards also refer to the military standards.

Secondly, the test flight application of these four fighters has directly skipped the engineering flight test stage. This is also the reason why Zhang Shanhu came to verify it so quickly. No one thought that the infinite gravity group was so unreasonable that it was ready to carry out the type test flight!

In other words, we often say the second stage of finalized flight test, which is the stage with the greatest risk, the longest time-consuming and the most subjects.

At this stage, from the basic flight performance of the aircraft to the edge subjects, from avionics system to airborne weapons, comprehensive test should be carried out according to the flight test program. Among them, avionics and airborne weapons flight test accounted for 60% to 70% of the total flight test.

Many strength boundary subjects and special conditions have great risks in flight test, such as stall, spiral, low altitude dive test, etc. of course, according to the actual performance of the fighter plane, we can also create highly difficult movements such as Russian "Cobra", "bell" and "360 turn".

Generally, after entering the flight test phase, it is generally required to fly about 1500-3000 hours safely (different aircraft may require different requirements), that is, at least hundreds of times, and several thousand more flights. If there are some problems during the test flight, the flight hours will have to be increased.

The last test flight is the test flight of weapon hitting target. After the completion of the finalized flight test, it does not mean that everything is well. Before the army is formally equipped, the operational effectiveness test flight should be carried out.

For example, launch and target test of various weapons in battlefield environment, verify the actual effectiveness of weapon system, and the proficiency of man-machine combined use of weapons.

However, this stage is often carried out by the troops to be installed. The units selected to be equipped with new aircraft must complete the test according to the subjects specified in the operational use outline of the new fighter aircraft before they are considered successful.

After that, the new fighter plane can enter the military service formally, and the initial combat capability can only be calculated after all pilots are qualified and reach the required number of fighters in service.

Another reason for the military to rush over to verify whether it is true or not is that the infinite gravity group actually added the weapon shooting process in the last stage in the flight test application, which made them even more unable to accept. Is infinite gravity group really ready to complete all the flight test work in one flight test!

More importantly, there is a message that the infinite gravity group has weapons that can be used!

What are the weapons that can be launched by heavy fighters? All kinds of missiles, of course! For all kinds of air-to-air missiles, air-to-ground missiles and other missiles with different functions, if the infinite gravity group owns the missiles, it is very easy to analyze the weapon test firing to be carried out in the flight test report they applied for.

After all, they said that they did not apply for missiles from the military when they said they wanted to carry out weapon tests. Moreover, according to the experience of infinite gravity group in helping the military develop various materials and parts for various types of missiles, the military can also accept that their company has the ability to develop missiles.

Besides, if you say that companies that can develop different kinds of rockets can't develop missiles, that's a lie. The technology difference is not very big.

However, in the view of the military, the infinite gravity group did not pay too much attention to weapons before. This is the reason why the confidentiality measures of infinite gravity group are in place. People who want to know can know that those research projects that do not want to be known can really guarantee that they will not be disclosed!

We should know that there are several kinds of weapons research projects being carried out by the infinite gravitation group. The research on missiles is the most common. This is also the reason why the military aircraft laboratory on the side of the aircraft company will directly tell the military that we want to carry out weapon test firing.However, those electromagnetic railguns that have been developed to the third generation, laser weapons developed to the fourth generation, and antimatter weapons that have begun preliminary research are still in high security.

Compared with these super weapons that will scare the whole world, it is normal for the company to choose to expose the related missile research and development projects at this time.

This incident was added to the flight test application report only after the company's permission was obtained, because the time for exposure is now ripe. Since the company began to publicize the lunar colonization program, the public opinion environment is not very friendly to the company.

All kinds of means, either overt or covert, have been applied to the company. Most of the products released by the infinite gravitation group are civil products. These products have little deterrent effect on the interest groups that admire the infinite gravity group. At this time, new deterrence measures are needed!

After all, even if the infinite gravitation group uses the fuel and maintenance technology of nuclear fusion power station as a deterrent, it can't be used frequently. Even when it can't be used, it's not a business of one company.

Therefore, this is the reason why Lei Tiantang, a five generation fighter who is clearly practicing, has come back to participate in the verification process in person. It is because the company now needs this kind of apparent deterrent!
