Speaking of how advanced this product is, what is its revolutionary nature?

There are mainly three points.

1. The speed must be fast enough to reach up to 1000 km/sec.

Second, be strong and comfortable enough, that is, good quality.

Third, it must be small in size and easily put into the space ring.

Because if you have a fast speed, you can reach it quickly no matter how far you go. Even if you are a billion kilometers away, it will only take more than ten days.

Fast speed also means running away quickly. If you encounter any danger, just accelerate crazy for dozens of seconds and quickly leave the danger far behind.

It is easy to understand to be strong. To accelerate to such a fast level, the acceleration must be quite large, and the atmospheric resistance is also very huge. After exceeding three times the speed of sound, you will face the problem of high temperature and thermal barriers, which is a great test for the fuselage material.

The purpose is naturally for safety.

Even for the sake of safety, it is inevitable to sacrifice a certain degree of comfort.

Finally, why do you need to be smaller? Isn’t it better to make it bigger, add a massage lounge chair, add a dining table, and then add a double bed and a separate bathroom to create a luxurious suite in the air?

However, other airlines have already made such luxury passenger aircraft, called the "Dream Bus" series, which currently accounts for more than 90% of the civil aviation market, making Yang Mengchao's small aircraft manufacturer unable to continue to be happy.

That's right.

In the past few years, I got the orders and the production line tasks were scheduled to Mengchao Aircraft Manufacturing Factory, which has been scheduled for a few years. Now that the orders are plummeting, I will not be able to survive.

The first generation of Mengfei Type 1 propeller aircraft has been technically eliminated.

The second flying backpack has more than ten competitors on the market, and its market share plummeted.

If you want to survive now, you can only take a gamble and develop a brand new flight product, position yourself in the high-end personal market, strive to occupy a place, and eat a piece of meat!

"The technology has improved too quickly, ten times faster than I expected. If this fails, my aircraft factory will either be acquired or I will switch to farming in the future."

Yang Mengchao said to Zhang Nan.

Zhang Nan also discovered that Yang Mengchao, who had been full of energy all day in the past two years, now frowned and seemed to be forced into a corner.

Moreover, Yang Mengchao is self-aware. With the technical strength of his small aircraft factory with less than 20,000 workers, it is impossible for him to give up the cake of the civil aviation market with millions of workers and thousands of technical talents.

Giant cargo spacecraft cannot be built.

We can only consider the individual market segmentation. The total population of Xinxia Country will exceed 10 billion in the future, and they are all populations with high consumption capacity. New personal aircraft, even if they attract one-tenth of the population to buy, can still sell millions of aircraft.

Moreover, the new aircraft must have a strong enough leading advantage, with advanced performance so that it makes it difficult for opponents to imitate, and even prevents the opponent from entering this market.

The only person who can give Mengchao Aircraft Manufacturing Factory such a technological advantage is Zhang Nan.

Therefore, I can only ask Zhang Nan for help.

"The most core factor in the advancedness of an aircraft depends on its power."

Yang Mengchao said: "As long as the power system is advanced, it is equivalent to the advanced of this aircraft. Others such as aerodynamic shape and control system can be adjusted and changed at any time, and the unchanged one is always the power."

"Now most of the flight products use Mijin nuclear power, but most of the engines are electric-driven turbofan engines with low thrust. Only a small number of them use high-temperature ion engines. The thrust is huge, but the cost is high and the volume is quite large. They can only be installed on large aircraft."

"This causes all civil aviation aircraft and civil aircraft to rarely exceed the speed of sound. Even civil aviation aircraft with small low-temperature ion engines to be equipped with a speed of more than 100 km/sec, because of the concern that the working fluid is not enough."

"So civil aircraft with flight speeds above 100 km/s is a market gap. As long as we can achieve technological breakthroughs and enter this gap, we can gain a foothold and eat this single meal, at least for a long time."

Therefore, the most core technology that needs to be broken through is to come up with a small-volume and large-thrust ion engine.

And it must be low-cost.

However, at the same time, to meet so many demanding requirements, can Zhang Nan do things that countless top power experts cannot do?

"I'll try."

Zhang Nan said in a deep voice, taking on this challenging task.

The reason why ordinary ion engines can generate large thrust is that the ejected plasma flow has a speed of more than 100 km/s or even thousands of km/s.

But accelerating plasma flow is very troublesome, and there are only two ways.

One is the strong magnetic field acceleration coil method, which allows the strong magnetic field to accelerate low-temperature plasma flow. The principle is like a particle collider, and the terminal speed can reach one-third of the speed of light, which leads to a huge engine size.

The second is the high-temperature electric field acceleration method, which allows a strong electric field to accelerate plasma with a high temperature of more than 100,000 degrees. It has a slightly smaller volume, but it has extremely high requirements for the material's high temperature resistance, resulting in huge costs.

So is there a third way?

Top power experts have not yet found a better solution.

Where is Zhang Nan?

Does he have that magical ability?

After thinking hard for a week, Zhang Nan thought of a clever method to miniaturize the plasma engine.

He applied a comprehensive solution idea.

Magnetic field acceleration, when used, can accelerate plasma flow of about 3,000 degrees to 10 km/sec, which is the primary acceleration.

When using electric field acceleration, the plasma flow at the engine port is heated with laser, and the temperature is increased to more than 10,000 degrees. After a strong electric field acceleration, the plasma flow can be accelerated to more than 100 kilometers per second, which is the secondary acceleration.

In addition, in the atmosphere, because working fluid can be seen everywhere, Zhang Nan set up a small turbofan engine inside the nozzle of the plasma engine, spraying flames of more than 3,000 degrees to generate the most powerful thrust - this belongs to the traditional power category, but in the atmosphere, this engine can provide 80% of the thrust source.

The three methods are combined.

Such a power complex can generate a maximum thrust of 12 tons - the total engine weight is 280 kg.

That is, the maximum thrust-to-weight ratio is 46.4.

The data seems quite average, and the internal structure of this engine is very complex and the parts are extremely accurate. Zhang Nan used light particle processing technology and magic shaping technology to successfully manufacture certain core parts and existing industrial technology.

But is the performance qualified?

Can it accelerate to 100 km/s or even more than 1,000 km/s?

Zhang Nan next conducted a three-month test flight.

The shape of the aircraft is like a round-headed bullet, three meters high, slightly thick at the bottom, with a triangle bracket, which can take off and land vertically. The main frame is black iron alloy, the shell is titanium alloy, and some high-temperature resistant materials, carbon fiber, and pure transparent amethyst tempered glass.

With the engine structure, the total weight is about 3.8 tons.

Maximum crew of 2 people.

The maximum acceleration is 3.16g.

Zhang Nan tried the maximum flight speed many times. After entering space, he exhausted all the working fluid and accelerated to 118 km/s.

It is far less than a thousand kilometers per second.

But...is it really that way?

Is there no room for further development?

"Accelerate the battle energy!"

Zhang Nan shouted softly and used his last resort.

The reverse thrust generated by the combination of combat air particles and working fluids, the aircraft began to slowly accelerate again.

119 km/s

200 km/s

500 km/s

It successfully broke through 1,000 kilometers per second, and it can continue to improve, as long as there are enough combat air particles in Zhang Nan's body.

But there is no need to continue to accelerate, otherwise slowing down will be a problem.

Of course, using magic particles to combine them with working fluids can also produce similar effects when using mental power to control them, allowing the aircraft to continue to increase its speed.

Therefore, the maximum speed limit for ordinary users is about 100 kilometers per second, and there is almost no maximum speed limit for the extraordinary. As long as the extraordinary is powerful enough, it can accelerate infinitely, or even close to the speed of light.

At the end of August.

Another month of finalized test flight was conducted, and thousands of details were adjusted and optimized.

The maximum thrust of the combined engine has been increased to 14.8 tons.

The total weight was reduced to 3605 kg.

The maximum speed is increased to 135 km/s. For extraordinary people with space rings on their hands to accommodate working fluids, there is no speed limit.

It is also named "Drill Bit Chasing Light" because it looks very similar to a drill bit and is extremely fast.

"Enough, this performance is enough!"

Yang Mengchao said excitedly: "I think other aviation giants cannot come up with a flight product that can match it, and it cannot be produced within at least ten years! In the short term, its performance cannot be surpassed by other products. In the personal high-end market, it will definitely occupy a place."

Because besides the speed.

It is also small enough to be stored in a space ring with a capacity of more than 50 cubic meters and can be carried with you.

The structure is strong and comfortable inside, and you can move around freely whether it is inside the atmosphere or in outer space.

In addition, it can also dive underwater, turn into a submarine, and carry out activities under the seabed of thousands of meters, without being blown up by powerful water.

Going to the sky and entering the sea, you can do everything!

If you are a super customer, you can also unlock faster speeds of thousands of kilometers per second.

With so many functions above, this is a must-have for home travel. High-end customers with a little bit of conditions should buy one.

It's just a little expensive, probably 800 million gold yuan per ship.

Because of its combined engine, only Zhang Nan can process it. He doesn't have much time. He took two hours a day and could only build 100 or 20 units, each charging a processing fee of 100 million yuan.

This also seriously limits the production capacity of the "Drill Bit Chasing Light" and makes it difficult to reduce costs, resulting in high prices.
