No matter what kind of transportation, the engine is the heart. Without it, there will be no power and no direction to move forward.

Aircraft engines are the jewel among engines, and their quality directly affects a country's aviation industry.

Unfortunately, China has obvious shortcomings in aircraft engines, and is lagging behind in both military and civilian use.

Military aircraft are related to the defense of a country's airspace. During wartime, a country without air superiority can only watch helplessly as it is attacked.

In this field, although China now has two outstanding third-generation aircraft, J10 and J11, their engines are all poor.

China's military aircraft engine technology was inherited from the Russians.

The Russians believed that during wartime, it would take no more than four hundred hours for a fighter plane to go from entering combat to being shot down. Therefore, their fighter planes were all designed according to this standard.

The life of an engine will end after four or five hundred hours.

This idea is understandable in wartime, but it is a waste of precious resources in peacetime.

Manufacturing an engine is quite difficult, and it would be a waste of money to have it scrapped after only a few hundred hours.

The biggest shortcoming of the Chinese Air Force is engine technology, which includes design, manufacturing and materials.

In fact, Chinese people are not behind others in design; they lag behind mainly in materials.

The lack of good materials will naturally affect manufacturing.

The engine's high-temperature resistant materials are the most critical part. Without good high-temperature resistant materials, it will be useless no matter how well you design and manufacture an engine.

If the material cannot support sufficient usage time, everything you say is useless.

The high-temperature resistant material accidentally invented by Xue Fengqin and Yang Li's team filled this gap and simply extended the life of China's engines to over a thousand hours. If further detailed research is carried out, it may be able to reach the level of American aircraft engines.

In the field of scientific research, there are many things that are connected one by one. If you make a breakthrough at a certain point, it is very likely to lead to the connection of several difficult points, or even solve a small problem.

With the favorable conditions of materials, Liming Factory overcame several engine material problems in one go.

As a result, China's engine technology seemed to have been transformed overnight.

It is a foregone conclusion that Xue Fengqin and Yang Li will win the first prize of the National XX Science and Technology Award.

Of course, the remaining corners of these technologies, when used on the carrier of lithium batteries, are sufficient to ensure that lithium batteries do not spontaneously combust under any conditions.

When talking about lithium batteries, we can’t talk about electric cars.

Nanwan Group's electric motorcycles now dominate the Chinese motorcycle market.

Since oil prices only rise and never fall, the price of oil products in China's market is currently between 4.5 yuan and 5 yuan.

The actual fuel consumption of a motorcycle is usually around two liters per 100 kilometers.

Don’t ever believe the 1.5 fuel consumption per 100 kilometers written in the manual. That refers to a brand new car.

The fuel consumption of a new car after one year cannot be sustained by more than 1.5.

This only refers to motorcycles below 100. For motorcycles like 125, even new ones require more than two liters of fuel, no more, no less.

As a result, the cost of fuel vehicles increases, and the advantages of electric vehicles become more prominent.

An electric motorcycle can be charged with basically one kilowatt-hour of electricity, and at most no more than two kilowatt-hours, and the cost is no more than one dollar.

It's better than riding a gasoline-powered motorcycle.

Especially for motorcycles in Nanwan, the range is over 100 kilometers. Office workers only need to charge the battery once every three days on average. The cost of riding such a motorcycle is only 30 or 40 cents a day, which is basically negligible.

This is the biggest reason why electric motorcycles have come into people's attention in the past two years.

In 2005, Nanwan Group sold more than 200,000 electric motorcycles, which was considered a small scale business.

As of September this year, Nanwan Group has sold electric motorcycles equal to last year's sales, and by the end of the year, the number of electric motorcycles is expected to exceed 300,000 units.

At this rate, the annual sales of electric motorcycles will reach 500,000 units in the next two years.

The former glory of Nanwan Motorcycle is about to make a comeback.

Electric motorcycles have begun to gain popularity, and now it’s time to officially launch the electric vehicle project.

Although Nanwan started developing electric motorcycles after the successful development of electric motorcycles a year ago, it was not officially launched as a project and was just a side job.

It is different now. We have formal projects, formal R&D personnel, and formal funding allocations.

Wanfeng has three requirements: a range of 600 kilometers or more, a set of batteries must have a mileage of no less than 70,000 kilometers, and parentheses: damage caused by human use is not included; the cost price of each ordinary electric vehicle shall not exceed 50,000 yuan.

He believes that as an electric car, no matter what it is made of, if it costs more than 100,000 yuan, it is a hooligan.

How can a pure electric car like the ones in later generations sell for three or four hundred thousand?

Just based on the configuration of the car?

Wan Feng plans to price his group's electric vehicles at no more than 100,000 yuan in the future, and the cost of replacing a battery pack will be between 10,000 and 20,000 yuan.

Of course! If the customer requires luxurious configuration, that’s another matter.

The electric car still continues the idea of ​​Nanwan electric motorcycle, relying on a powerful ternary lithium battery as the main power, and equipped with a powerful DC generator to continuously charge the battery during vehicle operation.

In this way, the vehicle's endurance will be greatly enhanced.

In the past, the three major components of electric vehicles were batteries, motors, and electronic controls.

Now, Nanwan Group has reduced the three major parts of electric vehicles into four major parts, adding a powerful generator, which is also the most important component.

How far a Nanwan electric car can travel depends mainly on how much electricity the engine equipped with this electric car can charge into the battery.

If the engine's charge capacity can match the battery's discharge capacity, theoretically the two electric vehicles could last forever.

But... this is simply impossible.

When the vehicle stops, it still needs to rely on AC power to supplement the power supply.

Why do engines need to use direct current?

Wan Feng recalled that in his previous life, the Chinese military had taken the direct current approach in researching electromagnetic catapults for aircraft carriers.

The West, however, adopted alternating current (AC), which resulted in numerous problems. Both the USS Ford aircraft carrier and the British all-electric destroyer remained half-finished, spending far more time at rest than at sea.

This also led the Chinese great scholar surnamed Ma to say the famous and domineering saying: If we want to be ahead, we must be ahead of the United States.

The route is correct, the next step is just a matter of timing.

After the electric vehicle project was officially launched, Lan Xinghan's team of more than 100 people immediately began researching and developing a higher-power engine.

Wan Feng believes that if Lan Xinghan's team can develop a high-power generator set, the military will be happy to adopt it.

In this way, China's future all-electric propulsion fleet may appear faster.
