Zhang Hao stood beside and watched quietly.

The plane began to roar, and the sound of the jet engine that Zhang Hao only heard in the movie was finally heard in reality. The sound was soft and surging, it was the sound of yearning for the sky.

A weak airflow erupted from the rear of the aircraft. The aircraft slowly taxied forward and came out of the warehouse. After aligning with the runway, the aircraft exploded with a burst of sound, and an incompletely burned red flame was ejected from the rear of the aircraft. But soon, the flame became blue, light blue, or even a light purple.

The engine's tail flame burst into tears in the air.

The plane accelerated rapidly, the roar went away quickly, and the plane quickly became smaller in the field of vision. For about a dozen seconds, the plane suddenly turned up, and then with a long roar, the plane pulled up and the landing gear began to gather.

It wasn't until this time that there was a strong wind on the runway.

The staff at the base covered their eyebrows with their palms, and watched the plane put on the sky like lightning. Compared with the propeller plane, the jet fighter is like a real roaming dragon. After rushing into the sky, the speed increases even faster.

The plane quickly became smaller at an unimaginable speed, and soon became a black spot. After that, the black spots also disappeared, and there was only a grand and low echo between heaven and earth, gradually disappearing.

But the work on the ground did not end there. A new set of equipment is working, this is... walkie talkie!

Of course, interphones relying on computer and chip technology still did not appear, but the researchers of the Ocean Group, using the array method and the magic weapon, have temporarily designed a highly practical solution.

They made a magic weapon, which is a ‘magic weapon’ engine with a keyboard. This is a full-size keyboard, which is also one of the by-products of computer technology research.

This keyboard can be used to send the combination code through the telegraph using the root or pinyin.

The telegraph on the other side can receive signals according to a single key of the keyboard, and then pass a magic weapon decoder to analyze the meaning of the other party.

Compared with the traditional telegraph, this brand-new method is more convenient, one person can fully manipulate it, and even does not need professional knowledge-just need to refine a new magic weapon, and this is not difficult.

Of course, if the telegraph is to send a signal, it cannot be placed in the storage space and must be taken out. This is the only trouble.

At this time, the telegraph staff kept reporting on the situation of the clouds in the sky. Following Yun Yangfan, there is also an engineer responsible for supervising the state of the aircraft.

In this aircraft test, the external array was not turned on at all—in fact, there was no external array on the prototype. Except for the porthole.

On the ground, Lin Yinghao, Zhu Min, Leng Fengxue and others could not care about Zhang Hao, and everyone was already busy. According to the report on the plane, they need to check and think about all the process steps and design defects.

Zhang Hao listened quietly without disturbing everyone. But soon Zhang Hao also discovered a little problem:

Airplanes cannot exceed the speed of sound! Even if the plane can fly to a terrorist altitude of 180 kilometers.

When it is relatively close to the ground, the air density is high, and the speed of sound can reach 500 meters, which is 1800 kilometers per hour; the plane cannot exceed the speed of sound.

After reaching the altitude of 180 kilometers above the aura, the air density drops and the speed of sound drops to 350 meters, which is 1260 kilometers per hour, but the plane still cannot exceed the speed of sound!

On the ground, the maximum speed of the aircraft can reach 1650 kilometers per hour, which is equivalent to 92% of the speed of sound-this speed is significantly higher than the speed of sound at high altitude.

But when it reaches high altitude, the maximum speed of the aircraft is only 1180 kilometers, which is only about 94% of the speed of sound at high altitude!

The plane can only reach subsonic speeds, but it can not break through the speed of sound anyway. There seems to be a powerful law that prevents the plane from breaking through the speed of sound.

Even after reaching the above subsonic speed, the aircraft began to tremble violently. According to the reports of Yun Yangfan and technicians, the aircraft was like a small wooden boat traveling in the wind and waves. It seemed to be able to disintegrate at any time. In that extreme flight, the whole plane creaked.

That is, the structure of the aircraft is solid, otherwise it has already disintegrated. At such extreme speeds, they dare not try too much.

"Strange!" Researchers on the ground whispered.

Without the help of spells to break through the speed of sound, there are many products of the Ocean Group. Whether it is a sniper rifle bullet or a shell, it can easily break through the speed of sound.

It makes no sense that such a sophisticated high-tech product of an airplane, and a sophisticated design, can't break through the speed of sound!

Is the plane too big? Everyone's fierce discussion also made the plane keep trying.

It even tried to dive the plane from high altitude, then shut down the engine, and used the power of falling to break through the speed of sound. But obviously this plan failed, the air resistance at the speed of sound was beyond imagination, and the speed of the aircraft quickly decreased after the engine was turned off.

The discussion was getting more intense, but at this time, Zhang Hao suddenly woke up, "Let the plane come back. I have an idea, maybe I need to verify it."

Then, Zhang Hao took out the flying sword and drew it on the ground. The concrete floor was cut by Zhang Hao, but it was very slight.

"Everyone sees, whether it's bullets, artillery shells, or ballistas, the overall lines are smooth and generally thick before and after. But the plane is not.

With the wings added, the central part is quite bloated! Like a fat man.

You give it a try to keep the ‘cross-sectional area’ before and after the plane consistent. Try to make the fuselage thinner. "

At this time, Zhang Hao did not directly state the "equal area rule". When breaking through the sound barrier, there will be a strong shock wave, which will form a complex fluid environment. However, it is possible to make the "overall structure" of the "overall structure" simpler to eliminate this effect.

The principle of equal area is this principle.

The so-called equal area is the sum of the cross-section of the aircraft from front to back, which is the same. So you see, all fighters are "small waists."

The "equal area rule" took five years of hard work by a large number of outstanding scientists on the planet to find out, and some pilots died as a result. As for the national wealth consumed by this process, it is even more difficult to estimate.

However, Zhang Hao did not want the Ocean Group to waste time on it.

Lin Yinghao and others doubted it, but let the plane return and began to study.

They first used a model to simulate in the wind tunnel, but it would take a month or two to complete the simulation and improvement. Zhang Hao encouraged everyone to leave a few words. Next, there is a more important thing to do-go with the Qinglong family!

After Zhou Xueyao's wake-up, Zhang Hao also felt that the twelve families could not be too laid-back, so that they could be laid out in the back. It is more important to show the muscles of the Ocean Group to this world.

Zhang Hao already had a plan in mind when the vehicle drove smoothly.
