As the aircraft entered supersonic speed, the roar of the aircraft breaking the sound barrier was also heard from the sky above the test base.

On the huge high-definition display screen, the speed of the aircraft also began to increase rapidly at this time, one time the speed of sound, 1.5 times the speed of sound, twice the speed of sound. When the speed of the aircraft exceeded Mach 3, at this time, everyone

Everyone became quiet, and he stared at the display screen closely, because once the speed of the plane exceeds Mach 3, the temperature of the nose of the plane will exceed 350 degrees, which is definitely a huge test for the plane.

If this aircraft is made of aluminum alloy and other materials, the temperature generated at such a high speed is enough to melt the aluminum alloy used to make the aircraft body. Therefore, ordinary supersonic aircraft will not exceed twice the speed

The speed of sound, because once it exceeds twice the speed of sound, the temperature of the aircraft nose will exceed 100 degrees Celsius.

In fact, this is the thermal barrier. When an aircraft flies at supersonic speeds in a dense atmosphere, due to the heating of the shock wave and the high-temperature compressed gas of the body, as well as the strong friction between the body surface and the air, the skin temperature of the aircraft will increase.

The aircraft rises sharply with the increase of Mach number. When the flight Mach number is 2.0, the temperature at the nose of the aircraft will exceed 100 degrees. When the Mach number reaches 3.0, the temperature on the surface of the aircraft will rise to about 350 degrees, which has exceeded

The extreme temperature of the aluminum alloy has been exceeded, which will greatly weaken the strength of the aluminum alloy.

However, although their aircraft is a very old aircraft, the material of this aircraft is a high-performance high-temperature resistant material with a melting point as high as 2000 degrees Celsius, so the supersonic cruise set by this aircraft

The speed is as high as Mach 3, and the ultimate speed reaches 6 times the speed of sound. If it is an ordinary aircraft, it will definitely be melted into scrap metal at such a temperature. After all, when the speed of the aircraft reaches 600 the speed of sound,

The temperature of the aircraft skin will reach over 1440 degrees.

When the aircraft's speed reaches Mach 3, the aircraft has entered the normal supersonic cruise state. Therefore, it no longer accelerates, but cruises at Mach 3 over the Dahua Empire.

5 minutes, 10 minutes, 30 minutes, an hour, the aircraft flew at three times the speed of sound for a full hour before finishing the supersonic cruise test flight, and then prepared to carry out the ultimate speed test on the aircraft.

test flight.

"Report the status of the aircraft!" After the aircraft flew for an hour at three times the speed of sound, the colonel who directed the aircraft to conduct tests from the airport tower said.

"The aircraft is in normal condition, with 60% power remaining and 55% water fuel remaining." The pilot's report came through the communication system.

"Now I order to conduct a maximum speed test."

"yes!"

Then, the speed of the plane increased again. Soon the speed of the plane reached 4 times the speed of sound, 5 times the speed of sound, 5.5 times the speed of sound, 5.9 times the speed of sound, 6.1 times the speed of sound. Finally, the mechanical speed of the plane stopped at 6.1 times the speed of sound.

, no longer rising, even so, it has already made the people present very excited.

You know, this is 6.1 times the speed of sound. This speed is far beyond the speed of all aircraft in the world. Even if the beautiful country gave it the Dawn model high-altitude and high-speed reconnaissance aircraft, its maximum speed can only reach a little more than three times the speed of sound.

, Even so, given the situation in their country, no Dawn high-altitude, high-speed reconnaissance aircraft has ever been shot down since it was put into service. After all, ordinary anti-aircraft missiles cannot reach this speed and cannot catch up with this speed.

aircraft, let alone shoot it down.

The entire podium, whether it was Zhang Yi himself, Minister Li and Minister Shi, all looked happy. It was obvious that they were very satisfied with the Q1 model engine of Colorful Stone Group.

"Mr. Zhang, the Q1 engine you provided is really excellent. Even this very old model of aircraft in our country can reach such speed after being installed with your engine. If it is installed in the latest model of our country,

On the plane, the performance of the plane will definitely be qualitatively improved." Shi Haiming said hilariously.

For an advanced fighter aircraft, supersonic cruise is definitely an important performance indicator. After all, it has absolute speed. It can not only arrive at the battlefield quickly, but also leave the battlefield at an absolute speed. In this way, the survivability of the fighter aircraft will be greatly improved.

improve.

Especially in this era, human civilization is constantly developing various missiles. Basically, as long as it is discovered and locked by the missile, it basically means being shot down.

But once the aircraft is equipped with this engine, it will be locked by the missile. With the extremely high speed of this aircraft, it can easily leave the battlefield, because at a speed of Mach 6, ordinary missiles cannot catch up at all, let alone

Said it was shot down.

"Mr. Zhang! I wonder when your Q1 engine can be mass-produced? Our military is ready to purchase such an excellent engine on a large scale. We are going to use your engine in all the aircraft we will produce in the future.

, Mr. Zhang, do you have the ability to provide it?" At this time, Minister Li said.

"Minister Li, the production line of our group's engine has been completed and will soon enter small-scale mass production. According to my prediction, within this year, if we go to Quarry Group to manufacture this engine with all our strength, at least

We can produce more than 500 engines, so Minister Li, please rest assured that our Qicaishi Group will definitely have no problems." Zhang Yi replied, patting his chest.

After maintaining a supersonic flight speed of up to 6 times the speed of sound for 10 minutes, the tower finally issued an order to end the maximum speed flight state. After all, at such a high speed, the aircraft's consumption of electricity and fuel is very scary.

In just 10 minutes, less than 10% of the power on the entire aircraft was left, and the water fuel was even less.

After testing these subjects, the aircraft quickly returned to the sky above the airport, and after making a large circle above it, the No. 8 fighter-bomber began to descend in altitude and land towards the runway.

When everyone saw that the No. 8 fighter-bomber base successfully landed on the runway, the entire test site suddenly burst into warm applause. Everyone applauded, and as the minister of the Dahua Empire Equipment Department, Minister Li even more

He held Zhang Yi's hand tightly and said happily: "Mr. Zhang, thank you so much. With this engine of yours, who will dare to say that the aircraft of our Dahua Empire are not good at engines in the future?"
Chapter completed!
