At this time, Cheng Feng, who received the microphone, stood up slowly: "I am very happy to receive the invitation from the master company, and I am honored to participate in such a meeting. Perhaps, this is the only one in China before the advent of the space age. This conference on the topic of space is also the first time that a nation has issued a slogan for self-improvement in the space age
Today, I am invited to come for two purposes. The first is to check the engine of the master company. It is said that this kind of engine technology has surpassed the current mainstream technology in the world. You can visit this later, and I will also explain it on the spot.
The other is to participate in this event, where I will publicly talk about some issues in the space age.
As we all know, space technology has already existed in the last century, and its representative product is: satellite.
But that's just the basics. Since then, both China and the world have experienced difficult development. The development of space technology is beyond imagination.
The first and most critical one is the technical issue. Researching space technology on the ground is one difficulty; and the completely different environment between space and the ground is another difficulty. For this reason, China supports a large number of researchers all year round to study space technology, and its annual investment is astronomical.
The second big difficulty is capital. The development of space technology and space exploration require huge financial support. On the ground, we calculate the cost per ton of goods transported. In space, however, we need to calculate the cost per gram of something.
In the early days of the development of space technology, the cost was once as high as one million US dollars per gram! Including all costs from research and development to final success. ”
"Ah..." Upon hearing this number, many people below were shocked! The value of gold has lost its meaning here!
Cheng Feng smiled slightly, "Even today, until 2040, the cost price of China's space technology is still at the level of 100,000 Chinese coins per gram. It was not until the participation and dedication of the master company that there was a breakthrough in 2042 progress. 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 today. The price per gram is 50,000 Chinese coins, which is reduced by half.
Today, before I came here, the National Academy of Sciences asked me to bring me an honor, an honor signed by the president of the country and belonging to Zhang Jingyuan and Gaoshou Company: Zhang Jingyuan was awarded the title of Honorary Academician of the National Academy of Sciences, and Gaoshou Company was awarded the title of National Pillar. Let us welcome together! ”
"Crash..." At this moment, the employees of Gaoshou Company had their hands swollen and were filled with excitement. Zhang Jingyuan was a little surprised that the president of the country signed it himself! ! !
“Next, let me talk about China’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 various sizes, and has a total weight of approximately 40,000 tons. The average cost per gram exceeds 200,000 Chinese coins, and huge amounts of money are invested in maintenance every year. There are tens of thousands of workers on it all year round, and the supplies consumed every day are astronomical.
The consumption of a space base has reached one-tenth of the country's annual expenditure!
Therefore, China's space base is now the second largest in space. The first place is the international space base that the United States has united with a large number of Western countries and has been expanded several times. There are also small bases launched by some countries one after another.
Another difficulty is that there are only more than 30 such people in China who are suitable for aviation pilots! In countries such as the UK and Germany, there are only three or five in the country.
However, this is all in the past and we should look forward. Next, let us award awards to the advanced employees of Gaoshou Company..."
The award ceremony was undoubtedly grand. Of the thirty award-winners, 15 received one million awards; ten received five million awards, four received tens of millions of awards, and one person received 20 million awards. This person, Li Yuzhang, actually solved the magnetic field compression function of the magnetic field sealed electronic leap-forward energy storage battery. Let the new battery produced by the master company control the weight to 2 tons, the core working area is 1.7 tons, the energy storage is 3 million degrees at a time, and the charging time is one hour - the premise is that there is so much power. In fact, the internationally common generator set takes one hour. The power generation capacity is between 300,000 and 1.2 million kilowatt-hours, and most of them are at the level of 600,000-800,000 kilowatt-hours. Let the expert company completely defeat the country's research technology only in battery technology. Of course, this requires a lot of investment in new materials by the master company.
Next, under the leadership of Zhang Jingyuan, reporters rushed into a huge and empty steel structure space that had just been opened by Gaoshou Company. Inside, it will be the workshop where the master company will assemble aircraft in the future. Of course, there is only one ugly airplane inside now, which is produced by Gaoshou Company. And, in the middle, there is a two-meter-long engine covered by semicircular tempered glass, which is today's star. On it, the K01 engine is marked with a nameplate.
"It's an honor for me to explain to you the general capabilities of this engine." Looking at this engine, envy flashed in Cheng Feng's eyes. The country's current plasma engine thrust is only 22 tons. The thrust of 20 tons just after leaving the master company has increased by two tons. But don’t underestimate these two tons. This is a manifestation of improved energy conversion efficiency. But compared with the 50-ton thrust successfully developed by Gaoshou Company, it is not enough. Many researchers are clamoring to send over the data from the master company and let everyone review and approve it together.
However, I am still excited that the expert company can let me explain such an engine. But he also calmly revealed some information that could be made public.
"Dear academician, can I take pictures?" a foreigner asked.
"Okay, you can't study it anyway!" After Cheng Feng said these words, he felt at ease. This is what people abroad said to me when I was young!
"Hello, academician, I am an aviation enthusiast. You just said that this engine can push a 60-ton aircraft. But as far as I know, the thrust-to-weight ratio of today's large aircraft is more than 10 times. Why can this engine only push 60 tons? , instead of 500 tons? ”
"You asked a good question. In fact, what you didn't notice is that this engine is for space research, not for flight within the atmosphere.
When flying in the atmosphere, the buoyancy of the air is a very huge force, and the engine only triggers this force.
But in space technology, the buoyancy of air is rarely used. Especially during the ascent, almost one ton of thrust can only push one ton of objects. It's just that when the plane is rising, it can still use part of the buoyancy of the air, so it's 50 tons pushing 60 tons. In addition, the gravity has been reduced far away from the ground. Even if the air is thin at this time, the gravity has been reduced to a certain level. Therefore, 60 tons is an ideal pushing ratio. ”
"Hello, academician, I am also an enthusiast." A reporter from CCTV came over, "Can you tell me, what is the position of engine technology like Gaoshou Company in terms of existing aero-engine technology?"
"Among the existing public information, it is the first!"
"Ah...but I remember that some rocket engines have a thrust of up to two hundred tons. Even China's own rocket engines have exceeded a thrust of 150 tons?"
"Haha, these are two technologies. Rocket engines are disposable and bulky. They require a large amount of liquid oxygen and kerosene, etc., and cause serious pollution. The current engine technology is for aircraft and aerospace aircraft engines. Can be used repeatedly.”
"Thank you, academician. By the way, how much does such an engine cost?"
"The details need to be kept secret. But you can calculate it based on ten times the price of gold of the same weight. This is the cost standard for all aero engines today." "Ah..." Everyone who heard this for the first time was shocked!
