A big country of aerospace with black technology

Just after Lei climbed down from the cockpit of the trainer plane.

Everyone came up one after another and began to ask questions about how they felt when the plane landed.

"How do you feel? Is the impact strong?" Yang Wei was more concerned about the pilot's own feelings.

As for those data, there are various records, which you can see later.

But pilots, as operators in the entire process, have first-hand experience intelligence.

"It's not very intense, it's not as exciting as when we did Falling Leaves!"

Lei Gang smiled and said.

After all, the speed of Teach 6 is not as fast as those third-generation machines or even fourth-generation machines.

Compared with some flying stunts, it pales into insignificance.

Lei Gang once tried to fly the fallen leaves in a J-20, and the feeling at that time was even more exciting.

If this landing experiment is compared to diving from a ten-meter high platform, then the difficulty of Falling Leaves is at least that of wingsuit flying at an altitude of 500 meters.

If you are not careful, your machine will be destroyed and your life will be ruined.

"It's still not enough this time. It would be even more fun if you could fly our carrier-based aircraft!" Lei Gang complained slightly unsatisfied.

As a special pilot who has flown advanced fighter jets capable of supersonic cruise, Lei Gang flies this old aircraft.

It always feels like an F1 racing driver coming to an amusement park to drive bumper cars.

"Carrier-based aircraft will be available soon, don't be too impatient!" Yang Wei said after listening.

"By the end of this year, you may be able to fly on the first domestic carrier-based aircraft."

Although it has only been more than a year since the project of domestically produced carrier-based aircraft was confirmed.

However, thanks to previous investment in heavy fighter aircraft, there are relatively few difficulties in carrier-based aircraft.

What's more, not long after the project was established, the country spent a lot of effort to obtain a prototype carrier-based aircraft and a large amount of design information from Ermao's family.

Although these materials are more than ten years old, they are still very helpful to the carrier-based aircraft design team that has almost no previous experience.

Speaking of folding wings alone, these design materials contain a large number of solutions, allowing Yang Wei and his carrier-based aircraft design team to fully refer to them.

When the domestic team purchased it, these materials were sold at a price that was almost free. These materials had been accumulated in the warehouse for more than ten years.

In the eyes of those managers, it may not be as valuable as a bottle of vodka.

Isn't this a tragedy? These materials that have cost so many scientific researchers are being sold at such a low price.

However, they will be reborn in the hands of a big country on the other side of the continent, which is another kind of luck that must be said.

The two points that Yang Wei and the others attach most importance to are naturally the folding wings and landing hooks that they have never had before, as well as the related adjustments to the fuselage structure and strength.

Of course, in addition to these two things, carrier-based aircraft also have many differences from land-based fighter aircraft.

Because the storage environment and combat environment are both in the sea with high moisture and high salt content.

It is necessary to strengthen the ability to resist moisture, salt, corrosion and wind and waves.

"Then I'll wait to fly our own carrier-based aircraft!" Lei Gang said excitedly.

Zhang Xingyang is also relatively happy. After all, the navy is stronger, which will give him more protection for his many subsequent big plans.

"Soon, soon." Yang Wei said:

"It is said that the repair of aircraft carrier No. 01 is progressing very quickly, and the day it will be put on board will not be far away."

Although the No. 01 aircraft carrier is a purchased hull, just this shell has saved everyone a lot of detours.

Otherwise, just the cabin arrangement inside the aircraft carrier would require a lot of effort to study.

Domestic theoretical research on aircraft carrier construction has never stopped. Technical research has been conducted in related aspects since decades ago, as well as related aircraft carrier battle group and tactical research.

"Is there really no problem with carrier-based aircraft?"

Zhang Xingyang asked curiously.

Although the basis of the carrier-based aircraft is the dual-engine version of the J-10S.

However, even Zhang Xingyang, the main developer of the dual-engine version of the J-10, is not particularly aware of the development progress of the carrier-based aircraft in this regard.

As for the various performance parameters of the carrier-based aircraft, it is even more unclear.

However, some of the requirements sent to the materials experiment center of the institute emphasized the corrosion resistance, moisture resistance, salt-alkali resistance and other properties of the materials. It can be seen that they have made a lot of enhancements to the material properties of the carrier-based aircraft.

Zhang Xingyang was naturally able to see part of the performance of the carrier-based aircraft from these materials.

For example, the enhancement of corrosion resistance and salt-alkali resistance of the core turbine disc of the engine has weakened its high temperature resistance to a certain extent.

Therefore, the engine performance of the carrier-based aircraft will decrease by about 5% compared with the land version of the fighter.

However, such a reduction is acceptable.

The dual-engine version of the J-10S has a combat radius of 1,500 kilometers.

This is excessive performance for a carrier-based aircraft.

Carrier-based aircraft have two roles in the entire aircraft carrier battle group.

The first one is to ensure the safety of the surrounding airspace of the entire aircraft carrier battle group. This only requires that the combat radius of the fighter jets be maintained at about 600 kilometers.

The second is to use the aircraft carrier as an airport to launch attacks on the enemy's shore targets or water targets. To achieve this, it is enough for the carrier-based aircraft to have a combat radius of 900 kilometers.

With a combat radius of 1,500 kilometers, the performance is not even a little bit excessive.

The ultra-long combat radius is somewhat inappropriate at this time.

Because the combat distance exceeds one thousand kilometers, it is easy to exceed the range of early warning aircraft and shipborne early warning radars.

In such an environment, it is difficult for carrier-based aircraft to perform well.

Moreover, it will further increase the logistical pressure on fuel, parts, etc.

Therefore, Yang Wei and others have also done a lot of work to reduce the weight of the carrier-based aircraft on the basis of improvements.

To this end, Yang Wei adopted a very bold design plan.

Although the J-10 S used a large area of ​​new materials to reduce its weight before, the dual-engine version of the J-10 needs higher body strength, so more aviation alloys are used to make up for it.

Yang Wei and the others directly used the new generation of high-strength carbon fiber that Longteng Group had just completed production as parts.

The weight of the carrier-based aircraft is reduced to a great extent.

Its take-off weight was reduced from about 32 tons to 28 tons.

"Based on our current testing, there are no problems!"

Yang Wei said confidently:

"Domestic carrier-based aircraft, if nothing unexpected happens, will be developed before the Spring Festival this year."

Although Yang Wei's speech was very similar to that of an old general on the stage, with flags all over his body.

However, Zhang Xingyang still chose to believe that he could complete his heroic speech.

Before the Spring Festival, complete the research and development of carrier-based aircraft!
