At this time, Cheng Feng, who received the microphone, slowly stood up: "I am very happy to receive the invitation of the master company, and I am also honored to be able to participate in such a meeting." Perhaps, this is the only conference on the topic of space in China before the advent of the space age, and it is also the first time that a nation has issued a slogan of self-improvement in the space age.

Today, I have been invited to come for two purposes. The first one is to check the engine of the master company. It is said that this engine technology has surpassed the mainstream technology in the world now, and you can visit this later, and I will explain it on the spot.

The other is to participate in this event, and it will also be at such a grand event that some problems of the space age will be openly discussed.

As we all know, in the last century, momentum has already had space technology, and the representative product is: satellites.

But that's just the basics. Since then, both China and the world have undergone arduous development. The development of space technology is beyond imagination.

The first and most critical is the technical issue. Studying space technology on the ground is difficult; And the environment in space is completely different from that on the ground, which is another difficulty. To this end, Huaxia has supported a large number of researchers all year round to study space technology, and the annual investment is astronomical.

The second big difficulty is capital. The development of space technology and the exploration of space require huge financial support. On the ground, we calculate the cost per ton of cargo transported. In space, however, we need to calculate the cost per gram of an item.

In the early days of the development of space technology, the cost was as high as one million dollars per gram! This includes all costs from R&D to final success. ”

"Ah......" Hearing this number, many people below were stunned! The value of gold has lost its meaning here!

Cheng Feng smiled slightly, "Even today, until 2040, the cost price of Huaxia's space technology is still at the cost price of 100,000 Huaxia coins per gram. It wasn't until the addition and dedication of the master company that there was a breakthrough in 2042. As a result, China's space technology has suddenly been brought to the level of the United States and Russia, and the cost price has dropped to the lowest level in the world. The price per gram is $1,000, or 50,000 Huaxia coins, which is half the price.

Today, before I came here, the National Academy of Sciences asked me to bring an honor, an honor signed by the president of the country that belongs to Zhang Jingyuan and the master company: Zhang Jingyuan was awarded the title of honorary academician of the National Academy of Sciences, and the title of national pillar of the master company was awarded. Let's welcome together! ”

At the moment of "lalala......" The employees of the master company were swollen with their hands, full of excitement. Zhang Jingyuan was a little surprised, the president personally signed the !!

"Next, I will talk about Huaxia's own space base.

After more than 30 years of accumulation, our space base has a diameter of 100 meters, contains more than 2,800 cabins of all sizes, and has a total weight of about 40,000 tons. The average cost price per gram is more than 200,000 Chinese dollars, and a huge amount of money is invested in maintenance every year. There are tens of thousands of workers on it all year round, and the daily consumption of materials is an astronomical amount.

The consumption of a space base has reached one-tenth of the annual expenditure of the country!

Therefore, today's Huaxia space base is the second largest in space. The first place went to the United States, together with a large number of Western countries, and the International Space Base, which has been expanded several times. In addition, there are small bases that are being launched one after another by a number of countries.

There is also a difficulty, that is, there are only more than 30 people who are suitable for aviation piloting! Countries such as the United Kingdom and Germany have only three or five in the country.

However, this is all in the past, and we should look forward. Below, let's award the advanced employees of the master company......"

The award ceremony was undoubtedly grand, with 30 winners and 15 people receiving millions of awards; Ten people received a reward of five million, four people received a reward of ten million, and one person received a reward of twenty million. This person, Li Yuzhang, actually solved the magnetic field compression function of the magnetic field sealing electronic leap forward energy storage battery. Let the weight of the new battery produced by the master company be controlled at 2 tons, the core working area is 1.7 tons, the energy storage is 3 million kWh at a time, and the charging time is one hour - the premise is that there is so much electricity, in fact, the power generation of the international general generator set in one hour is 30-1.2 million kWh, most of which are at the level of 60-800,000 kWh. Let the master company defeat the country's research technology only in battery technology. Of course, this is indispensable for the investment of a large number of new materials by master companies.

Next, under the leadership of Zhang Jingyuan, the reporters poured into a huge empty steel structure space that had just been opened by the master company. This will be the workshop where the master company will assemble the aircraft in the future. Of course, now there is only one ugly plane, produced by the master company itself, and, in the very middle, there is a two-meter-long engine shrouded in semicircular tempered glass, which is the star of the day. Above, the K01 engine is marked with a nameplate.

"It's an honor for me to explain the approximate capabilities of this engine." Looking at this engine, envy flashed in Cheng Feng's eyes. The thrust of the country's current plasma engine is only 22 tons, and the 20-ton thrust has increased by two tons after leaving the master company. But don't underestimate these two tons, this is the table for the improvement of energy conversion efficiency. It's just that compared with the 50 tons of thrust successfully developed by the master company, it is a little insufficient. Many researchers clamored and sent the number of master companies over for approval.

However, I am still excited that the master company can let me explain such an engine. But he also calmly said some information that could be made public.

"Honorable academician, can I take a picture?" A foreigner asked.

"Yes, you can't figure it out anyway!" After Cheng Feng said this, he only felt that his mind was smooth. When I was young, people abroad said this to myself!

"Hello academician, I am an aviation enthusiast. You just said that this engine can propel a 60-ton aircraft. But as far as I know, the thrust-to-weight ratio of large aircraft is now more than 10 times, why can this only push 60 tons, instead of 500 tons? ”

"That's a good question. What you don't notice is that this engine is for space research, not flight in the atmosphere.

Flying in the atmosphere, the buoyancy of the air, is a very large force, and the engine just triggers this force.

But in space technology, the buoyancy of air is rarely used. Especially during the ascent, almost a ton of thrust can only push a ton of objects. It's just that when the plane is rising, it can still use part of the air buoyancy, so it is 50 tons to push 60 tons. In addition, at a great distance from the ground, the gravitational force has decreased, and even at this time the air has thinned out, and the gravitational force has been reduced to a certain extent. So 60 tons, is an ideal push ratio. ”

"Hello academician, I am also a hobbyist." A CCTV reporter came over, "Can you tell me what kind of position is the engine technology of a master company in terms of the existing aero engine technology?" ”

"Among the existing public information, it is the first!"

"Ah...... But I remember that the thrust of some rocket engines has reached as much as 200 tons, and even Huaxia's own rocket engine has broken through the thrust of 150 tons, right? ”

"Hehe, these are two techniques. The engines of rockets are disposable, and they are bulky, requiring large amounts of liquid oxygen and kerosene, etc., which are highly polluting. And the current engine technology, which is the engine of the aircraft, the aerospace aircraft, can be used repeatedly. ”

"Thank you, Academician. By the way, how much does such an engine cost? ”

"There is a need for secrecy. But you can calculate it at ten times the price of the equivalent weight of gold. This is the cost standard for all aero engines today. ”

"Ah......" Everyone who heard about this for the first time was stunned!
