Eagle Sauce: What? Rabbit wants to rebuild Guanghan Palace!

"Academician Sun, what kind of engine is used in this fourth-and-a-half-generation fighter you developed?"

"Does it really have the same maneuverability and stealth as the Free Nation F-22?"

After reacting, Zhao Jinsong grabbed Sun Zhiyuan's hand and asked excitedly.

Looking at Zhao Jinsong's excited appearance, Sun Zhiyuan's heart was also full of relief and pride.

All he did was to make their dragon kingdom strong.

Now, Zhao Jinsong's happy attitude, he also empathizes.

"General Zhao, this fourth-and-a-half-generation fighter I developed uses a binary vector engine. "

"Although it is the same technology as the engine used in the Free Nation-22, the engine I developed surpassed them in all performance figures. "

"As for stealth performance, don't worry, the stealth coating of this fourth-and-a-half-generation fighter alone is a generation ...... more advanced than the F-22."

Sun Zhiyuan patiently explained to him.

His answer shocked Zhao Jinsong and the rest of the senior generals of the Fengtian Military Region Air Force again.

You know, according to the standards set forth by the free nations.

A qualified fourth-generation fighter must have a full 4S standard.

Namely, super-maneuverability, stealth, over-the-horizon strikes and supersonic cruise.

As the core part of the fighter, the engine is powerful or not, which is directly related to the fighter's super-maneuverability and supersonic cruise capability.

The quality of the stealth coating is related to the stealth ability of the fighter.

Now that these two technologies are more advanced than the F-22 fighters of the Free Country, then there is no doubt that this is a fourth-and-a-half-generation fighter.

"General Zhao, the Ten-Winged Angel is about to take off. "

"Although I am confident in the performance data of this fighter. But I think it's the actual test that is more reassuring and convincing. "

Sun Zhiyuan said with a smile.

Hearing his words, everyone present also nodded.

No matter how beautiful the theoretical data is, it has not been tested by flight tests, and it is only paper data after all.

Only after the actual test flight of this fighter can those theoretical data become a reality.

Boom

However, just when everyone looked at the fourth-and-a-half-generation fighter on the runway again.

The tail vent under the Ten-Winged Angel's fuselage suddenly erupted two fiery blue flames.

The entire fighter plane climbed rapidly from its initial speed like an arrow off the string.

The numerous wings on either side are adjusted in response to the changing air currents.

A few seconds later.

With a thunderous roar, this fourth-generation and a half fighter continued to climb into the air like an eagle.

In an instant, it was thousands of meters in the air.

......

The Dragon Kingdom has a unique path of fighter development and development.

According to the flight test standards of the Dragon Kingdom, a fighter needs to go through three stages of rigorous flight test tests.

Only when these three test flight procedures are completed can the final type be finalized and put into active service.

The first stage of engineering test flight is a new type of fighter developed in accordance with the design ideas proposed by the military, and after the production is completed at the manufacturing plant, the first flight verification must be carried out.

This is generally carried out at the test flight site of the aircraft factory.

It is used to verify the basic safety and operability of the aircraft, and to ensure that the aircraft can fly safely on its own.

In the first test flight, the test flight staff will take into account the problems found in the first flight and the opinions put forward by the military.

The design of the fighter was partially modified, and the fighter was repeatedly inspected through test flights, so that the design defects were exposed and modified one by one, and then the test flight was carried out again.

Only after all aspects have been met, the second qualitative test flight can be carried out.

However, the fourth-and-a-half-generation fighter developed by Sun Zhiyuan is already perfect, and there are almost no flaws in the design.

After being sent to Shenfei Industrial Group, they have already asked the test pilot to complete the first test flight procedure.

And this time, with the participation of the Air Force, it will directly enter the second stage of test flight work.

This stage is called the finalized test flight, which is the most risky, time-consuming, and subject-to-subject test flight stage.

From the basic flight performance of the aircraft to the marginal subjects, from the avionics system to the on-board weapons, all are thoroughly tested according to the flight test syllabus.

Many intensity boundary subjects and special state test flights are very risky.

For example, stalls, augers, low-altitude dive test flights, etc.

Of course, it can also be tested according to the actual performance of the fighter.

And after the finalized test flight is completed, it does not mean that everything is fine.

The fighter will also undergo the final stage of test flight, that is, the test flight of combat effectiveness.

For example, various weapons are launched in the battlefield environment, target shooting tests, and the actual effectiveness of the weapon system is verified.

and proficiency in the combined use of weapons by man and machine, etc.

However, the third phase of the combat effectiveness test flight could not be completed at the test flight base of Shenfei, and it needed to be handed over to the Air Force for testing.

......

And at the same time as this Deparachime fourth-and-a-half-generation fighter took off.

The staff responsible for the test flight monitoring below also began to report various test data of the fighter plane.

"The report shows that the climb rate of the fourth-and-a-half-generation fighter is 278 m / s, and the lift coefficient is about 2.3, and the data is confirmed. "

"The fighter's avionics system has been turned on, and a variety of receivers and transmitters are operating normally. "

"The fighter currently reaches an altitude of 6,000 meters above the ground, which is in line with the flight test altitude. "

The testers of Shenfei Industrial Group reported to Ji Xiaodong and others the status of the fighter at this time and the test data.

What?

The lift coefficient can reach 2.3.

The overall lift coefficient announced by the Free Country F-22 is only 1.7!

It's so big all at once!

After hearing the data reported by the testers.

Zhao Jinsong and the senior generals of the Fengtian Military Region Air Force couldn't help but exclaim.

In aircraft design, the lift coefficient is often used to evaluate the lift performance of the wing and the fit of the wing to the fuselage.

Through the accurate calculation and analysis of the lift coefficient, the drag and energy consumption of the aircraft can be effectively reduced, and the flight efficiency of the aircraft can be improved.

In aircraft performance evaluation, the lift coefficient is also used to evaluate the aircraft's performance indicators such as climb rate, maximum speed, and maximum flight altitude.

The greater the lift coefficient, the less drag the aircraft has, the easier it is to fly.

At the same time, it also indirectly means that it is more mobile.

And this fighter has a lift coefficient of up to 2.3, far exceeding the F-22 fourth-generation fighter of the Free Country, and it is definitely the first lift coefficient of Blue Star!

But.

It is different from the exclamation of Zhao Jinsong and the senior generals of the Fengtian Theater Air Force.

Liang Guodong, Li Haocheng and others, who have long been familiar with the technical performance of this fourth-generation and a half fighter, were not too surprised.

Hearing the tester's words, Ji Xiaodong nodded calmly, picked up the walkie-talkie and continued.

"Remind the pilot that the next step is to conduct a stall flight test. "

"This test is very dangerous, please adjust the state of the fighter and stall after 10 seconds. "

Heard Ji Xiaodong's words.

The faces of all the people present also became serious.

Stalling is an extremely important and at the same time extremely dangerous test.

Once there is an operational error, or the fighter loses control, it is very likely that the plane will be destroyed and people will be killed.

Previously, the test pilots of the Dragon Kingdom had a stall test mistake and died.

So for this test, everyone held their breath.

I'm afraid that something will happen.
