Hand rubbing nuclear fusion live in the wilderness

Chapter 345

There are quite a few replacement materials for polychloromethane in KRW's hands.

Even considering the low temperature of minus [-] degrees during the lift-off process, there are quite a few that meet the performance requirements.

It's just that these materials are much more difficult to manufacture than polyhydrogen chloride cooling materials.

Polyhydrogen chloride resin is one of the most cost-effective materials among various materials, and it is not very difficult to manufacture. It can be synthesized through some uncomplicated chemical methods, and the manufacturing conditions are not very particular.

This is also the reason why Won chose this material as the slow temperature material of the middle layer before.

There are also disadvantages, that is, when faced with ultra-low temperatures exceeding minus [-] degrees, crystallization will occur and the performance of the material itself will be reduced.

But this kind of shortcoming is not a shortcoming at all when it is placed on the materials used to buffer and lower the temperature of hundreds of degrees of high temperature.

After all, under normal circumstances, almost no equipment needs to withstand the high temperature of nearly [-] degrees and the ultra-low temperature of minus [-] degrees at the same time.

Won didn't think about this kind of thing at first. The space shuttle is not stationary when it lifts off, it is always flying at high speed.

Under such circumstances, the low temperature of minus [-] degrees could still appear, which he hadn't calculated or expected at the beginning.

After thinking about it, he rummaged through the knowledge and information in his mind, and soon he found several materials that met the performance requirements.

Picking from the middle, Won locked the choice on a material called 'heterogeneous cyclopentane polyethylene glycol'.

This material is a colorless material derived from the liquid insulation material 'cyclopentane' developed by humans.

It can still maintain a certain fluidity at minus 55 degrees, just like a non-Newtonian fluid, and it will not start to condense until minus [-] degrees, which will reduce some light transmittance, but there is no problem in applying it to the space shuttle.

The disadvantage is that the upper limit of temperature insulation performance of this material is not as good as that of polyhydrogen chloride grease, and the upper limit of temperature control is not so high, and it can only work at temperatures below 730 degrees.

No matter how high it is, it will boil and quickly turn into gas, which greatly hinders the transmission of light.

Fortunately, the HY laminate material on the surface of the aircraft will lower the temperature once, and the temperature transferred to the middle layer will be much lower.

In addition, Won has increased the circulation speed of 'heterogeneous cyclopentane', allowing the liquid on the heat-absorbing surface and heat-dissipating surface to flow at a faster speed, which can still meet the heat reduction requirements.

In addition, this 'heterocyclopentane' material is toxic to humans, with a mild pungent odor.

The toxicity is not very high, but it is corrosive to the human body to a certain extent, but as long as you don't drink a few mouthfuls or inhale the gaseous liquid, it is no problem to wash off the skin in time.

Although it is poisonous and corrosive to a certain extent, it is for living things.

This material can be used as a heat insulation material in the middle layer of the space shuttle. Anyway, it is a fully enclosed environment, as long as it is not corrosive to other materials, there is no problem.

It took some time, and Won successfully manufactured this 'heterogeneous cyclopentane polyethylene glycol' material.

This is something in the primary chemical application knowledge information, and it is not difficult for him with complete materials.

The tricky thing is to inject the insulation material exchanged from manufacturing into the middle layer of the space shuttle.

The structure of the middle layer is relatively complicated. On the whole, there are borders like countries in the world, which are separated by blocks, not a whole.

Therefore, it is unrealistic to release the original polyhydrogen chloride grease through the pipeline and then fill it with heterogeneous cyclopentane polyethylene glycol material. In addition, it is necessary to thoroughly clean up the 'polyhydrogen chloride grease' material inside. Area by area to deal with.

After more than three days of tossing, Han Yuan replaced the new insulation material.

Of course, before this replacement, he had done enough high and low temperature performance tests on the material in advance to ensure that there was no problem with the heterogeneous cyclopentane material before replacing it.

After completing the replacement of the middle layer material and waiting for the second launch of the zero space shuttle, another week passed.

With the experience of the previous test, Han Yuan made some slight adjustments to some of the set programs and commands by checking and analyzing the log files and the photos passed by the space shuttle.

The adjustment is not big, only a few parameters related to the execution of wrong commands are slightly changed.

The space shuttle can go to the sky and return normally, which shows that there is no problem with the orbit he calculated before, the preset order and the backup order.

So there is no need to adjust these things as a whole.

Besides, the number of overall commands is too large. You must know that it took him more than a month to write these things before.

For more than a month, except for daily use and study at night, I basically didn't do other things, and I was all used to write these programs.

There are more than 100 preset commands. Under each preset command, there are at least a dozen backup commands, and there are dozens of backup commands at most. These backup commands are all judged according to different situations.

Under some standby commands, there are secondary standby commands.

If you want to modify it, it will be extremely troublesome. Not only do you need to consider various situations, but you also need to do a lot of derivation and calculation.

If you want to change everything, you have to change it in the Year of the Monkey.

However, it is not so easy to modify the wrong command parameters.

Each preset command at least involves two preset commands before and after, and also involves the following backup commands.

Therefore, at least two adjacent preset commands and their backup commands must be considered when modifying the wrong command.

After completing all preparations, the space shuttle Zero took off again carrying five tons of liquid xenon, Korean won and the blessings of the audience in the live broadcast room.

After launching the space shuttle into the sky, Won continued to manufacture unfinished communication satellites non-stop.

Before the return of the next space shuttle, he has already manufactured most of the parts of the "Zero Satellite", and it will take another day for the remaining small parts and assembly.

24 hours passed quickly, and the space shuttle zero arrived as scheduled and landed on the test site again.

After the targeted testing was completed, Han Yuan showed a relieved smile on his face.

The effect of the new insulation material that was replaced was not bad. Judging from the data recorded by the thermometer deployed on the surface of the gallium lanthanide silicon solar power generation panel, the highest temperature during the entire flight did not exceed [-] degrees.

Although there are still erroneous commands in the adjusted command set, the previous seven have been reduced to two.

Overall, the effect is very good, there is nothing to adjust.

Of course, if you like, you can make some adjustments to execute the commands for the two errors.

After completing the second test of Space Shuttle Zero, Won parked the space shuttle in two different corners of the test site, along with the Lero delta craft.

This kind of space shuttle is more suitable for him, but for the countries watching the live broadcast, the reference significance is greater than the practical significance.

Four tons of liquid xenon will be consumed in one flight, and no country will fail to replicate this kind of thing.

Unless it is used for military combat operations, it will consume two billion yuan at one time, and it will be so bad that you have to sell your underwear.

However, the above electromagnetic propulsion system, the technology and materials used in the protective layer and thermal insulation layer of the space shuttle are still very good.

These things can be disassembled and studied thoroughly, and there are many places where they can be applied.

But these things are far less valuable than electric propulsion-free fluid engines with extremely low energy consumption.

The electric propulsion-no propellant engine forced the five permanent members to hold a United Nations meeting to revise the upper limit of airspace and military treaties of various countries.

Airspace refers to the air space above territorial land and territorial waters under the jurisdiction of national sovereignty.

As for how high a country's airspace should be, there is currently no clear regulation in international law.

However, it is generally believed that the flight altitude should not be lower than that of traditional aircraft, which is about [-] to [-] kilometers above the ground.

Generally, the default is about 35 kilometers.

With the in-depth research of electric propulsion-free engines by major countries, almost all major countries have deployed electric propulsion engines to fighter jets.

And an aircraft equipped with electric propulsion-free medium engine can easily fly to a high altitude of tens of kilometers.

This altitude has broken the tacitly recognized airspace altitude of all countries.

It can be said that an engine has changed the mode of warfare in the past few decades.

In the past century, although all countries have been researching high-altitude weapons or high-altitude strategic bombing methods.

But no one could have imagined that in such a fast future, the threat would rise from a maximum of twenty kilometers to a hundred kilometers in the air.

This kind of thing is a strategic threat just like a nuclear bomb.

Fortunately, this thing is not independently developed by a certain country, but all countries have it and check and balance each other.

Otherwise, if a country with a strong will to launch a war, such as the United States and the island country, gets this thing alone, I am afraid that a new round of war will start again.

A fighter plane that can climb to an altitude of [-] kilometers is no less deterrent than nuclear weapons.

For countries that can carry and launch missiles, conventional missiles and nuclear missiles are nothing more than replacing a missile head.

Especially when fighter jets are equipped with electric propulsion engines, they can fly to an altitude of nearly [-] kilometers, and it is not easy to carry nuclear weapons.

In addition, the fighter planes of various countries do not need to use gallium lanthanide silicon solar panels to provide power, so further improvements can be made in terms of concealment.

The most important thing is that after the application of the electric propulsion engine, the endurance of the fighter jet has exploded.

The more advanced and faster the fighter jet, the higher the requirements for fuel, as well as the weight and performance of the fighter itself.

Today's fourth-generation and even fifth-generation fighter jets in various countries generally have a cruising range of no more than [-] kilometers when two fuel tanks are installed.

In other words, its combat radius is only about [-] kilometers.

This is still a fairly advanced fourth-generation or even fifth-generation fighter.

If it is one or two levels worse, the combat radius is even only more than 1000 kilometers.

Like the "White Swan" developed by Big Brother, a bomber with a cruising range of 1 kilometers once refueled is just one of them.

In contrast, the F-22 Raptor fighter jet in the United States has a cruising range of [-] kilometers, which is directly reduced to scum in seconds.

It can be said that Lao Maozi is almost alone in the world relying on the white swan.

It's a pity that this advantage is lost when the electric propulsion non-propellant engine is applied to fighter jets.

At the beginning, Won flew the Lero delta aircraft around the entire earth twice. Although solar power panels were used to supplement energy, it can be seen that the battery life and performance stability of electric propulsion.

Especially in Huaguo, the third leader in research and development and the first leader in improvement.

After initially mastering the technology, Huaguo produced a fighter jet with a cruising range of more than [-] kilometers.

Endurance is close to half of the equator.

This means that this kind of fighter jet can reach any corner of the world after taking off from the mainland of China.

What's more, the military's science and technology department has also applied lanthanum gallium silicon solar panels and lithium-sulfur batteries to small fighter jets.

The shape and overall shape are almost completely imitated by the Leluo triangular aircraft made by Korean Won, but the wingspan is longer and wider, and more solar panels can be arranged on the surface.

The difference is that these solar power panels are covered with a layer of movable armor. When flying into the sky, the armor can be opened to allow the power generation panels below to provide electricity.

When needed, it can be closed again, providing extremely high radar concealment effect.

For this kind of fighter, if the external solar power generation panel continuously provides electric energy, the cruising range can be achieved to the extreme.

In other words, as long as the electric propulsion-free medium engine is not overloaded, it can always fly in the sky.

Moreover, in addition to the external solar power panels that can provide electrical energy, the fighter itself also has its own electrical system, which can provide a certain amount of backup electrical energy.

In addition to endurance, because of the simulated vertical take-off and landing, with the assistance of high intelligence, this fighter can fly at ultra-low altitude.

This means that he can break through the radar defense lines of most countries, and even go deep into the enemy's country to detect the enemy's situation.

Because radar is flawed.

The detection range of the current military long-range warning radar is about [-] kilometers. If it is an over-the-horizon radar, the detection distance can reach several thousand kilometers.

If it is a specific radar or a high-power radar, the detection range can cover almost the entire low-Earth orbit.

But no matter what kind of radar, there are certain blind spots.

The most serious blind spot is the area close to the ground.

This is because electromagnetic waves propagate in a straight line. Due to the limitation of the curvature of the earth and the influence of mountains, radar detection will produce certain blind spots.

The closer to the ground, the larger the blind area, which causes the radar to fail to see low-altitude and ultra-low-altitude flying targets.

All ground radars will have an ultra-low altitude blind spot, and this blind spot can only be made up by early warning aircraft and alpine radar stations.

If an aircraft can fly at an altitude of less than 100 meters, coupled with the complex terrain of mountains and forests, it is entirely possible to avoid radar tracking and sneak into other countries without being discovered.

If the defense is penetrated at a height of ten meters or less, it can break through almost all radar networks except early warning aircraft and alpine radar stations.

However, early warning aircraft and alpine radar have great restrictions.

In the 90s, someone drove a light plane from Europe all the way to Moscow.

It was not discovered until it landed in Red Square, relying on ultra-low altitude flying to avoid radar monitoring.

Of course, if you want to use this method to enter the capital, Chaoyang people will be the first to refuse.
