A big country of aerospace with black technology

Before the new year, the J-10's test flight work was already under intensive preparations, mainly because there were still some minor problems in the adaptation process with the WS-10.

After the Spring Festival, all preparations are almost done.

In the past few days, ground tests have just been carried out.

Checked the status of the J-10 fighter jets when they were taxiing on the ground.

After a series of ground tests, the J-10 will finally have its maiden flight at the end of February.

Because the WS-10 engine used by the J-10, the core components of the turbine and the exhaust nozzle are all made by the Rocket Research Institute.

Therefore, as a collaborative development unit, Zhang Xingyang also has the opportunity to be a representative of the R\u0026D unit.

Came to Tianfu City, where Chengfei is located, and visited the first flight of the J-10.

"Xing Yang, you have worked hard this journey."

Zhang Zhengjiang, the chief engineer of the WS-10 project, warmly shook hands with Zhang Xingyang.

"It's not hard, I came by plane, and the business class is quite comfortable."

Zhang Xingyang was also very happy and excitedly shook hands with Zhang Zhengjiang.

"Has the J-10 test flight time been confirmed?"

Because the test flight has to take into account the weather conditions of the day, Zhang Xingyang didn't know when the J-10 will take the test flight before coming.

I only know that the approximate time for the test flight is within two days of tomorrow.

"For the weather in these two days, the answer given by the Meteorological Center is that the weather conditions in these two days are relatively good, and there is no cloudy or rainy weather."

"They just completed the division of the test flight airspace today, and applied for an airspace, and the time is tomorrow!"

The airspace for the test flight needs to be applied in advance, but the competent authority for this part of the work in China is the Air Force, and it is easy to apply for it.

"Then it seems that the time for me to come is just right!" Zhang Xingyang said with a smile.

"How has WS-10 performed recently?"

Since participating in the first flight of the Su-27 equipped with the first modified WS-10 engine in October, things at the Rocket Research Institute were so heavy that it exploded.

Zhang Xingyang didn't have much time to inquire about the follow-up improvements and flight status of WS-10. Naturally, he didn't know much about its latest status.

"Recently, according to the improvement direction you provided before, we have made a lot of changes."

"The performance has indeed been improved to a certain extent. Without the afterburner, it can also maintain the cruising speed of Mach 0.98 of the Su-27 fighter jet. With the afterburner on, it can reach the supersonic speed of Mach 2."

"If you continue to improve the engine performance in the future, after the thrust goes up, it is possible to achieve supersonic speed in the cruising state."

Supersonic cruise is a relatively advanced concept these days, and there are not many fighter models that can do it.

The MiG 31 developed by Mao Xiong before barely touches the edge of supersonic cruise. It has a fuel capacity of 16.3 tons and can allow him to fly at supersonic speed for 15 minutes.

But in general, it is considered to be truly capable of supersonic cruise if it can maintain a supersonic flight time of more than 30 minutes.

The F-22 newly secretly developed by Yingjiang also has supersonic cruise capability, but it has not been successfully developed yet, and there is still a long way to go before it can be put into the battlefield.

The same Typhoon fighter jointly developed by the four countries of Europa, although also designed to have supersonic cruise, but the first prototype just flew for the first time three years ago, and there are still a lot of troubles that have not been resolved.

It can be said that in this era, there is still no fighter jet with real supersonic cruise, which has actually been put into practical application.

If we can really catch up with the international level at this time, then the following days will be much easier.

After all, in international competition, the real backing is the strength of the respective countries.

A large part of the strength is supported by the combat effectiveness of the army.

"After your improvements, can the J-10 achieve supersonic cruise?"

Zhang Xingyang asked a little curiously, the J-10 that used the AL-31F engine in the previous life was naturally unable to achieve supersonic cruise, but after applying the WS-10 of this world, there is still a question mark about whether it can be used.

"this"

Hearing Zhang Xingyang's question, Zhang Zhengjiang also felt very helpless. Even with many improvements, the thrust of WS-10 can only reach 2.85 tons without afterburner.

This thrust is difficult to maintain supersonic flight for a long time.

"To be honest, it is difficult to achieve supersonic cruise in the true sense, but there should be no problem with intermittent supersonic cruise."

"The aerodynamic layout of the J-10 makes it face too much shock wave resistance when it is in a critical state, and it can't be overtaken without afterburner."

The J-10, which uses an external pylon, faces too much shock wave resistance when mounting missiles, and the engine thrust must be at least 3 tons to push the aircraft to a supersonic state.

"If no missiles are mounted, I am sure that the J-10 can maintain supersonic cruise."

Hearing this, Zhang Xingyang rolled his eyes. Can a fighter jet without missiles still be called a fighter jet?

It can only be counted as someone else's target drone!

"So the new generation of fighter jets must have the capabilities of all-weather stealth, supersonic cruise, and high-altitude perception."

"To achieve stealth and supersonic cruise, it is necessary to use a built-in magazine."

Zhang Xingyang expressed his views on the next generation of fighter jets, especially in terms of layout.

These are actually designs that have gone through the test of war and been recognized by everyone in later generations, but they are indeed relatively new to everyone at this time.

"Furthermore, as a single-engine light fighter, the J-10 itself has certain shortcomings, such as a small ammunition load and a short range."

"It will definitely not be able to meet the growing combat needs of the Air Force in the future!"

"Especially over the vast ocean to the south, the Air Force needs aircraft with a larger combat radius."

"Only twin-engine heavy fighter jets can meet these demands of the Air Force!"

Zhang Zhengjiang didn't think much of it yet, after all, everyone's latest generation of fifth-generation aircraft was still under development at this time.

In China, the project has not even started, and it is a bit far to consider these.

"If the J-10 is successful, it can be considered advanced in the world, and the situation is not as bad as you said."

Zhang Zhengjiang's understanding of the situation was not as detailed as Zhang Xingyang's, so he was naturally more optimistic.

It's not easy for Zhang Xingyang to attack him anymore, and just like Zhang Zhengjiang said, at this time the J-10 can barely meet the air force's combat requirements.

From an economic point of view, the Air Force at this time really needs light fighters.

As for the new generation of twin-engine heavy fighters, I will definitely participate in it. After all, no one in this era knows better than me how to design and manufacture an advanced fifth-generation fighter!

If you participate deeply, the domestically produced fifth-generation fighter may even become the world's first fifth-generation fighter!
