Chapter 220 Wind Tunnel Test Needed

With the burning of the 2500-degree flame-throwing device, the charred blackness of the star rock material on the surface of the raw egg has indeed deepened a lot compared to before.

However, after 10 minutes of continuous baking, the material did not undergo various plastic changes such as softening and creep.

This made everyone happy. The black spots on the burnt surface are just some carbonization and oxidation reactions on the surface. As long as there is no problem with the structure of the main body of the material, it can take on its due role.

After another 5 minutes of baking, the surface layer no longer continued to change.

Xiao Luo turned off the flame of the spray gun, put the gun back into the spray gun holder, and used a tool to pinch a little bit of the star rock material from the roasting place, and gave it to a colleague next to him for physical and chemical experiments.

And the most important thing left is to see if the eggs inside have been heated under the 2500-degree roasting. To be able to resist the temperature, but also to ensure that the heat can not be transferred.

Under the watchful eyes of everyone, Xiao Luo put on special gloves and used a tool to peel off the star rock coating bit by bit.

When the egg was completely peeled out, everyone's nervousness reached its peak. The next moment, it was time to verify whether their research and development was successful.

Luo Xiao held the egg in his hand and shook it unobtrusively. In fact, he already had the answer in his heart, but he still needed to use the final steps to give everyone and himself a final result.

Xiao Luo pointed the egg at a table next to it and tapped it lightly. With a click, the eggshell shattered, and the egg yolk and egg white inside slipped out along the crack, and fell to the ground with a clatter.

It is raw!
"Success!" Seeing this, everyone finally couldn't help clapping their hands and celebrating. The eggs that were cooked at 600 degrees for 2 seconds just now are still raw after being baked at 2500 degrees for 15 minutes.

There is only one explanation, that is, the 'star rock' material completely insulates all the heat, even if the slightest bit does not pass into it, and this is exactly the result they want.

The live broadcast experiment 30 years ago was reproduced in Fan's laboratory today!

From the grilled part analyzed by another researcher and the follow-up more comprehensive experiment, it is also concluded that the 'star rock' material really reproduces the human world!

Jiang Fan, as the person in charge of Fan Lab, also received the news immediately, and he was also very happy. This is also a milestone for the current research and development of aviation development.

The heat insulation of Xingyan is not the same as the previous heat-resistant tungsten-carbon alloy. The heat resistance is mainly used in the components themselves. The temperature of the components themselves can be very high, but it is only necessary not to cause deformation and other plastic changes.

But the heat insulation is different. The heat insulation coating needs to completely isolate the transfer of heat. After all, even if the fighter jet can withstand the high temperature of 1000 degrees, the pilot inside cannot withstand it, so there is an essential difference in the use of the two.

Moreover, what Jiang Fan saw from the Xingyan thermal insulation material is not only the significance for aviation development, but also it will bring about major changes in many fields.

For example, tank trucks, ships, and containers loaded with petroleum and chemical raw materials will be a disaster if they explode or catch fire due to heat transfer from the sun.

And as long as a layer of star rock coating is applied on it, the occurrence of such tragedies can be greatly reduced.

Another example is the military field, including tanks and warships, which are highly airtight, and iron products absorb heat, so the internal temperature is very high, and refrigeration equipment needs to be turned on with high power to adjust the temperature.

However, if the star rock coating is used to achieve better heat insulation effect, it will greatly save its energy consumption for refrigeration.

The same fuel can drive chariots and warships farther.

Of course, Jiang Fan did not forget that when watching the individual exoskeleton performance at the exercise base, the stars also mentioned a very important field where it can be applied.

So he immediately picked up the phone and called over there.

For aeroengines, the interpretation of basic technical data in various fields has been completed. The following is the use of the results of these basic technologies to study how to apply them to aeroengines, so that all aspects of their performance can be achieved in just a few months to a year. Time spans the distance of 30 to 50 years for others.

In addition to the research of Aviation Development itself, the construction of relevant testing facilities and places of Aviation Development is also on the agenda.

Foremost among these is the wind tunnel.

Because the estimated thrust of the engine developed this time has reached an astonishing level, the conditions of the existing wind tunnel facilities cannot well support its performance test, so Jiang Fan held a meeting with the responsible personnel of the Aviation Development Institute, Discuss how to solve the problem in the wind tunnel.

Firstly, I arranged for personnel to introduce the overall situation. Because several external administrative and financial leaders were invited, the introducer also added a paragraph about the use of the wind tunnel:

"Wind tunnel is generally called wind tunnel test. Simply put, it is based on the principle of relativity of motion, fixing the model or object of the aircraft in the artificial environment on the ground, and artificially creating airflow to simulate various complex air conditions. Flight status, get test data.

This is the "green channel" for the development and production of modern aircraft, missiles, and rockets.Simply put, the wind tunnel is to artificially create a "sky" on the ground.

And because the high-thrust engine we developed this time involves high-altitude flight, it also needs wind tunnel tests to check relevant parameters.

And because it is a super-thrust engine, the relative flow velocity and change of airflow under high-speed flight are completely different from the airflow conditions faced by low-speed engines, and the complexity is not the same.

It is also because of this situation that our existing wind tunnel equipment in several places across the country can no longer support this scale of aviation wind tunnel testing, so we need everyone to see how to solve this problem. "

After the question was raised, just after we had an exchange, an expert from the Institute of Mechanics, Chinese Academy of Sciences, raised his hand and said:

"This is not a problem, the JF-22 ultra-high-speed wind tunnel we are researching should be able to meet your requirements.

It can reproduce the flight conditions at an altitude of 40 to 100 kilometers and a speed of up to 10 kilometers per second, which is equivalent to about 30 times the speed of sound.

I think no matter how powerful the thrust of your aviation engine is, it will not exceed 10 kilometers per second, haha.

Of course, our initial design was mainly aimed at the country's major needs in the space field of space-to-earth flight technology and the cutting-edge exploration of high-temperature aerodynamics, and to solve the experimental research problems of ultra-high-speed flight technology.

But if our aviation development progress is so fast, then we can fully meet your needs by doing some adaptive transformation in advance.

This piece of technology has been perfected, and the issue of deployment and installation is currently being considered. The deployment is based on field conditions, and it will only take a few months in a short time. It should be able to catch up with the test of our new aviation development. "

The words of the experts from the Institute of Mechanics lifted everyone's spirits, and Jiang Fan also took a reassurance.

Then the next question arises, where to build?
