Zhang Hao stood aside and watched quietly.
The plane began to roar, and the sound of jet engines that Zhang Hao had only heard in movies in the past was finally heard in reality. That kind of sound is light and surging, it is the sound of yearning for the sky.
A weak airflow spurted out from the rear of the aircraft. The aircraft slowly taxied forward and arrived outside the warehouse. After aligning with the runway, the aircraft burst out with an explosion-like sound, and incompletely burned red flames spewed out from the rear of the aircraft. But soon, the flames turned blue, light blue, and even light purple.
The exhaust flames of the engine erupted in the air with a sharp sound like tearing.
The plane accelerated rapidly, the roar quickly disappeared, and the plane quickly became smaller in the field of vision. After about ten seconds, the plane suddenly tilted up. Then with a long roar, the plane rose from the ground and the landing gear began to retract.
Until then, there was no strong wind on the runway.
The staff at the base covered their brows with their palms and watched the plane fly across the sky like lightning. Compared with propeller aircraft, jet fighters are like real dragons. After rushing into the sky, their speed actually increases 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 majestic and low echo between heaven and earth, gradually dissipating.
But the work on the ground did not end there. A new set of equipment at work, this isa walkie-talkie!
Of course, walkie-talkies relying on computer and chip technology have still not appeared, but researchers from Dayang Group have used the idea of ????formation and magic weapons to temporarily design a very practical solution.
They made a magic weapon, which was a 'magic weapon' level 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 use root words or pinyin to send combination codes through the telegraph machine.
The telegraph machine on the other side can receive signals according to individual keys on the keyboard, and then use a magic decoder to analyze the meaning of the other party.
Compared with the traditional telegraph, this new method is more convenient and can be completely controlled by one person. It does not even require professional knowledge - it only needs to refine a new magic weapon, and this is not difficult.
Of course, if you want the telegraph to send signals, it cannot be placed in the storage space and must be taken out. That's the only trouble.
At this time, the telegraph personnel kept reporting on the clouds and sails in the sky. Following Yun Yangfan was an engineer responsible for monitoring the status of the aircraft.
This aircraft test does not enable external formations at all - in fact, there are no external formations on the prototype. Except for the portholes.
On the ground, Lin Yinghao, Zhu Min, Leng Fengxue and others no longer care about Zhang Hao, and everyone has begun to get busy. According to the report on the plane, they need to check and think about all process steps and design defects.
Zhang Hao listened quietly and did not disturb anyone. But soon Zhang Hao also discovered a small problem:
Airplanes cannot exceed the speed of sound! Even if the plane can fly to a terrifying 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 1,800 kilometers per hour; the aircraft cannot exceed the speed of sound.
When we reach above the aura layer and reach an altitude of 180 kilometers, the air density drops and the speed of sound drops suddenly to 350 meters, which is 1260 kilometers per hour, but the aircraft still cannot exceed the speed of sound!
When on the ground, the maximum speed of the aircraft can reach 1,650 kilometers per hour, which is approximately equivalent to 92% of the speed of sound - this speed is significantly higher than the speed of sound at high altitudes.
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 aircraft can only reach subsonic speeds at its maximum, but it cannot exceed the speed of sound in any case. There seems to be a powerful law that prevents aircraft from breaking the speed of sound.
Even if it reaches the above subsonic speed, the aircraft begins to tremble violently. According to reports from Yun Yangfan and technicians, the aircraft is like a small wooden boat shuttled in strong winds and waves, and it seems that it can disintegrate at any time. In that extreme flight, there was a creaking throughout the plane.
?That is, the aircraft structure is solid, otherwise it would have disintegrated. And at such extreme speed, they didn't dare to try too much.
"Weird!" The scientific researchers on the ground whispered to each other.
To break through the speed of sound without the help of magic, Dayang Group has many products. Whether it is sniper bullets or artillery shells, they can easily break the speed of sound.
There is no reason for aircraft to be so sophisticated and high-techThe product, which has been precisely designed, cannot break the speed of sound!
Is the plane too big? Everyone's heated discussion also made the plane try again and again.
They even tried to make the plane dive from a high altitude, then shut down the engine and use the force of the fall to break the speed of sound. But obviously this plan failed. The air resistance at the speed of sound was beyond imagination. After the aircraft turned off its engine, its speed quickly decreased.
The discussion among the people became more and more intense, but at this time, Zhang Hao suddenly came to his senses, "Let the plane come back. I have an idea, maybe it needs to be verified."
Then, Zhang Hao took out his flying sword and started drawing on the ground. The cement floor was scratched slightly by Zhang Hao, but only slightly.
"As you can see, whether it is bullets, cannonballs, or ballistae, their lines are generally smooth and thick from front to back. But airplanes are not.
With the wings added to the aircraft, the central part is quite bloated! Like a fat man.
??You try it and make the ¡®cross-sectional area¡¯ of the front and rear of the aircraft consistent. Try making the wing part of the fuselage thinner. "
At this time, Zhang Hao almost didn¡¯t point out the ¡°equal area rule¡± directly. When the sound barrier is broken, there will be a powerful shock wave and a complex fluid environment will be formed. However, this effect can be eliminated by making the 'overall structure' of the 'aircraft's appearance' simpler.
And the law of equal areas is this principle.
The so-called equal area means that the sum of the cross-sections of the aircraft from front to back is the same. So you see, all fighters have "small waists".
"The 'Law of Equal Areas' took five years of hard work by a large number of outstanding scientists on the earth to figure it out, and some pilots died because of it. As for the national wealth consumed by this process, it is even more difficult to estimate.
¡°But Zhang Hao doesn¡¯t want Dayang Group to waste time on this.
Lin Yinghao and others were doubtful, but they still let the plane return and started research.
They first used a model to simulate it in the wind tunnel, but it would take a month or two to complete the simulation and improvements. Zhang Hao encouraged everyone and left. Next, there is more important thing to do - fight with the Qinglong family!
After Zhou Xueyao¡¯s reminder, Zhang Hao also felt that the Twelve Families should not be allowed to be too leisurely and let them have time to arrange things in the back. What¡¯s more, we need to show the muscles of Dayang Group to the world.
The vehicle was driving smoothly, but Zhang Hao already had a plan in mind. (Remember the website address: www.hlnovel.com - Didn't finish reading?
