The leaders and guests were naturally very happy to see such a beautiful fighter.

Today's offline ceremony was still presided over by the beautiful Yunxia, who stood on the stage and said with a smile: "Distinguished leaders, guests and friends, good morning. Today is a beautiful day, it is the day when our Peregrine Falcon fighter comes off the assembly line, I believe everyone knows that the Peregrine Falcon fighter is an epoch-making fighter, it will become the first aircraft in human history to be able to fly at supersonic speed, and it will also become the most advanced and powerful air superiority fighter, I think we are all proud of it! ”

After a round of warm applause, Yunxia invited the leaders of the Eighth Route Army to the stage to speak.

The leader of the Eighth Route Army said very happily: "Representatives of the Allied Forces, comrades, today we are indeed about to usher in a new era, our air combat forces will soon enter a supersonic era, I believe that we will not only have the Peregrine Falcon, a supersonic fighter, we will also have more advanced supersonic combat aircraft!" ”

The applause was very warm, and the representatives of the Allied forces also came to the stage to speak, and it could be seen that the senior representatives of the Allied forces had a light in their eyes, and they very much wanted to get this advanced supersonic fighter!

It can be said that these fighters made by the Eighth Route Army are also a symbol of the friendship between China and the allies, and they are the most important weapons in the fight against the Fascist front.

Today, the Peregrine fighter can be successfully rolled off the assembly line, it can be said that the contribution of the allies is not small, after all, the development of these advanced fighters requires a lot of money and materials, and almost all of these money and materials are obtained from the allies.

After the leaders' speeches, it was a very interesting part, and the leaders and guests cut the ribbon for this supersonic fighter together.

Next, it was even more exciting, everyone stood in front of the peregrine falcon fighter and took a group photo, and then the leading guests couldn't wait to gather around the peregrine falcon fighter to visit.

The leaders of the Eighth Route Army took the lead in sitting in the cockpit of the peregrine fighter and experienced the feeling of a supersonic fighter pilot.

Although there is no way to fly now, the feeling of sitting on the cloud is still very refreshing, and the leaders are laughing from ear to ear.

When it came to the representatives of the Allied forces, these people were also happy, after all, such an advanced fighter plane, they would soon be able to get it, how could it not make people happy.

The reporters even slapped at this advanced, futuristic supersonic fighter.

Although it is still a yellow primer, it is already very beautiful, very sci-fi, and it would be better if it was given a beautiful paint.

The workmanship of the peregrine fighter is also more advanced, which is also the reason why it is a supersonic fighter, after all, when flying at supersonic speed, the requirements for the airframe process are higher.

Now Duan Peng is also surrounded by reporters, and everyone is interested in supersonic fighters.

A reporter asked: "May I ask Director Duan, how does the peregrine falcon fighter achieve supersonic flight?" ”

Duan Peng smiled: "Well, it's very complicated to say. In order to make the aircraft achieve supersonic flight, first of all, it must have strong thrust, as the so-called force brick fly, as long as the engine thrust is large enough, then no matter what aircraft can exceed the speed of sound, but supersonic aircraft, in terms of aerodynamic design, also need to conform to the principle of supersonic flight. Otherwise, it will disintegrate directly in the air, so our peregrine fighter, as you have seen, has a smooth fuselage, especially the design of the bee waist, which is a design that conforms to the supersonic area law! ”

A reporter asked again: "Supersonic area law, can you ask Director Duan to explain it?" ”

Duan Peng said with a smile: "Of course, this supersonic area law was discovered when we were designing, and it refers to the relationship between the zero rising wave resistance of the aircraft and the distribution of the cross-sectional area of the aircraft along the longitudinal axis of the aircraft when flying at transonic or supersonic speeds. According to the area law, it is possible to reduce the resistance of transonic or supersonic waves when designing aircraft, and improve the transonic and supersonic flight performance of aircraft. The area law also provides a simplified method for estimating the wave resistance of an aircraft, replacing the calculation of the wave resistance of a complex aircraft with the calculation of the wave resistance of a simple equivalent spin body. Therefore, the area law is bound to be widely used in the design of transonic and supersonic aircraft. ”

After these advanced design concepts were explained by Duan Peng, the reporters were very interested.

Of course, how it was designed, Duan Peng would not announce it, after all, this is a secret.

If the little devils learn it, it will be a big trouble to make their supersonic fighter.

A reporter asked: "May I ask Director Duan, how is the performance of our peregrine fighter?" ”

Duan Peng smiled: "That's definitely not said, it's definitely the first in the world." First of all, you see, the maximum flight speed of the Peregrine Falcon fighter can reach Mach 1.6, which is 1.6 times the speed of sound, which makes it easy to occupy the advantage of speed and altitude in air combat. ”

Then Duan Peng talked about the performance of the Peregrine Falcon fighter in detail.

This fighter not only flies fast, but also flies high, with an altitude of 16,000 meters, which is much higher than that of a propeller fighter.

The Peregrine Fighter has five attachment points, which can hang a three-ton pendant, mainly three auxiliary fuel tanks to increase its range, and two rocket launch nests.

With three auxiliary fuel tanks attached, the range of the Peregrine Falcon fighter can reach 3,300 kilometers, which is very amazing.

Even without hanging the auxiliary fuel tank, it has a range of 2,300 kilometers, which is flown out of internal fuel.

On the whole, the Peregrine fighter is close to Duan Peng's previous life, the Thunder Dragon fighter, the J-7 MF fighter, or the Gripen fighter.

It's just that it belongs to the first generation of supersonic fighters, and the avionics weapon system is definitely lagging behind the fighters of a few decades later.

But in this era, it is an invincible opponent who can rely on a double-barreled cannon to defeat the whole world.

The Allies had ordered 2,000 Peregrine Falcon fighters, which was a staggering order.

And the Allies also want to get a license to produce, so that maybe more than 5,000 supersonic fighters will be built.

Don't say 5,000, it's 500, you can sweep away the little devils.

Of course, it is not excluded that the little devil is also developing a supersonic fighter, after all, now the little devil has obtained German jet fighter technology.

And it is also possible for them to obtain some technical information on Chinese jet fighters from the Allies or elsewhere, so that it is still possible to build supersonic fighters.

The off-line ceremony was a complete success, and the leaders and delegates were very satisfied.
