The degree of difficulty is simply beyond people's imagination.

Unlike submarines, the weight of an aircraft is designed to be calculated in grams, which can be said to be haggling.

Because the greater the weight of the aircraft, the smaller its payload, when this indicator deteriorates to a certain extent, the aircraft loses its practical significance.

In order to shield radiation and cooling needs, the weight of the nuclear reactor at that time was several thousand tons, and it was unimaginable to fly such a huge heavy object.

Of course, there are also issues such as the threat of nuclear radiation to people.

"Actually, the concept of this nuclear aircraft was proposed as early as the 50s."

Jiang Haichao said to Ye Tian with a smile.

Paused.

He shrugged: "Of course, it's all about foreigners. We were poor at that time and our family was weak. We didn't think so much."

Ye Tian also laughed.

Although I haven't personally experienced that period of time.

But he still knows.

once Upon a time.

When we didn't even have a computer, we just relied on the abacus to calculate Ms. Qiu's data clearly.

Jiang Haichao continued: "In engineering, because the nuclear reactor is too heavy to lift it into the air, in the desperation of not being able to solve the technical problem, in order to reduce the weight, the engineers have proposed to hire old crew members to solve the radiation problem.

The rationale was that they were old enough to die of other causes before they developed fatal cancer from the radiation.

Sacrificing the lives of the elderly to achieve the goal of strategic nuclear strikes was a kind of age discrimination that existed in that special period, and it was not generally recognized. "

Ye Tian sneered.

This kind of thinking can only be imagined by some countries.

At least,

In his cognition, our country will not allow this kind of thing to happen.

But Ye Tian also knew.

If nuclear aircraft can really succeed, it does have great advantages.

Aeronautical nuclear propulsion enables aircraft to fly around the world, allows bombers to stay in the air for several days, and can cover any target around the world without refueling.

They only need a home base, no landing anywhere else, no aerial refueling.

You must know that aerial refueling is the most vulnerable moment for military aircraft, and the cost of maintaining overseas military bases is also astronomical.

of course.

There are also many problems.

In addition to efficiency issues, aviation nuclear power is more importantly a safety issue.

Once a nuclear leak occurs in the air, the pollution will quickly spread to all parts of the world.

Protecting pilots from radiation hazards is even more difficult to solve. No one flies a plane that they know will kill them.

Seeing Ye Tian's pensive look, Jiang Haichao said with a smile: "The idea of nuclear-powered bombers was abandoned after intercontinental missiles came out. After all, from a military point of view, nuclear aircraft became irrelevant because intercontinental missiles Ballistic missiles avoid all the problems of manned nuclear flight. They have a one-way mission, no refueling, and no pilot to operate. There is no military need for nuclear bombers, and funding dries up.”

Needless to say, Ye Tian understood what happened next.

Time passes.

With the development of nuclear technology, it seems that some people are interested in the plan of nuclear aircraft.

speak up.

This has something to do with myself.

Ye Tian's recently completed nuclear propulsion reactor technology belongs to micro-reactors in terms of category.

and.

During the development process,

Ye Tian casually developed a new type of fuel.

This is a three-layer isotropic fuel specially used for micro-reactors, and it is a high-abundance low-enriched uranium fuel.

This fuel can still maintain structural integrity after high-temperature fission. It is designed to consolidate nuclear fuel inside a structure composed of graphite and ceramic materials, which can withstand higher temperatures and prevent the core from melting, even if the structure is destroyed. Fuel pellets also minimize leakage of radioactive material.

Its biggest advantage is higher safety performance.

and.

According to Ye Tian's estimation, this reactor can use high-abundance low-enriched uranium fuel with a concentration of 5% to 20%, with a power generation of 200 kilowatts to 15 megawatts, and an operating time of more than 10 years.

Weighing no more than 40 tons, it can be transported using standard military transport, including trucks, ships and aircraft.

and.

Once the military small nuclear reactor is successfully applied, it will be used for new concept weapons with extremely high energy requirements such as ship or land-based laser weapons and electromagnetic guns, as well as high-power electronic warfare equipment.

…

Furthermore, it is the progress of nuclear fusion reaction.

Nuclear fusion reaction is like making a miniature sun. One of its advantages is that it does not have insurmountable radiation hazards like nuclear fission reaction.

The high temperature and pressure at the core of the sun fuse hydrogen and helium atoms together, releasing amazing amounts of energy.

Scientists try to replicate the physical conditions of nuclear fusion in the core of the sun, so that deuterium and tritium can undergo nuclear fusion reactions under these conditions to obtain energy.

Today, our country has technically realized a high-temperature and high-pressure environment for nuclear fusion.

Use a light beam to squeeze a ball containing deuterium and tritium, compress the ball to 100 times the density of lead, and heat it to more than 1 million degrees Celsius, which is higher than the temperature at the center of the sun. Under this condition, deuterium and tritium are combined to form Heavier helium, while releasing enormous amounts of energy.

However, nuclear fusion reaction has a long way to go from theoretical experiment to practical application.

On this road, it is still necessary to solve many problems that are still difficult to overcome, such as fuel extraction, energy conversion and utilization.

"How about it, are you interested in trying it?"

Jiang Haichao looked at Ye Tian, and asked slowly: "Yingjiang can't walk, let's go?"

PS: I have tried my best to keep it simple, but there are still a lot of technical terms, please understand!five.

stunned!

Confused!

At this moment, Ye Tian's expression was like this.

He really didn't expect it.

Jiang Haichao actually made this request to himself.

"Grandpa, are you kidding me?"

Ye Tian said helplessly to Jiang Haichao: "Whether it's micro-nuclear reactors or nuclear fusion technology, they are not mature enough, and they don't even have practical applications. How can we build airplanes?"

"Haha, look at you, what are you in a hurry for?"

Jiang Haichao said with a smile: "What I mean is that you pay attention to the information in this area first, and don't rush to do it. We can wait."

"........."

Ye Tian was speechless.

The old man said it lightly.

But don't forget.

This is a nuclear powered aircraft.

Looking at these experts in the entire country today, who else understands the "[-]" of aero engines and nuclear propulsion better than yourself?

After all.

This is still a job for myself.

"You are the one."

Jiang Haichao looked at Ye Tian with a serious expression, and said to him seriously: "Sometimes, you just make yourself too nervous."

Taking a meaningful look at Ye Tian, Jiang Haichao said, "You have to know that scientific research cannot be completed overnight. Some projects may take one generation or even several generations to complete. ,do you understand?"

Ye Tian was taken aback.

He also heard this sentence from the professor.

only.

At that time, Professor Yu was talking about our country's aviation probe program.

"The country's investment of billions, the efforts of tens of thousands of people, ten years of youth..."

When the teacher said this, his eyes were slightly red.

It was difficult for Ye Tian to understand the feelings in the hearts of the older generation of scientific researchers.

After all, empathy is actually difficult.

"Master, I probably understand what you mean."

Ye Tian took a deep breath and said to Jiang Haichao.

Jiang Haichao laughed: "It's good to understand, just remember, no matter if I'm here or not, you're not going forward alone, you still have like-minded people, and people who care about you."

???

Ye Tian was startled.

Then he raised his head and looked at Jiang Haichao.

There is something in the old man's words!

"Little guy, many people are optimistic about you, and we are all waiting for you to bring us more surprises."

Jiang Haichao looked at Ye Tian, and said word by word: "No matter where you are, there are people protecting you, so you can do the research you want to do with confidence."

!!!

Speaking of this, if Ye Tian didn't understand what it meant, he would be an idiot.

He really didn't expect it.

I actually received so many people's attention.

No wonder the Security Bureau has always paid special attention to me,

Even negative news about myself on the Internet was dealt with very quickly.

At first he thought it was the country's emphasis on scientists.

Now it seems.

I'm afraid this is just for myself.

Could it be that.

Has the existence of the system been known?

With such a thought flashing through his mind, Ye Tian's expression turned a little ugly.
