Chapter 3213 A new generation of semi-solid foam propulsion fuel
【Revision】
Speaking of this, Yu Chengwu showed a proud look, and then said to Wu Hao and Zhang Jun: "If we can stably increase the number of uses of the core first-stage rocket to more than twenty times, then we are confident that the rocket will be used every kilogram.
The carrying cost is reduced to the thousand yuan level, making it the medium-sized launch vehicle with the lowest carrying cost among rockets of the same level in the world.
Even for the Jianmu-9 heavy-lift launch vehicle, we can reduce its average transportation component by about 50 percent."
After hearing Yu Chengwu's detailed introduction to the engine data, Wu Hao and Zhang Jun both had smiles on their faces.
Zhang Jun said happily: "In this case, the cost of our aerospace projects can be further reduced in the future."
Speaking of this, Zhang Jun asked: "Why not replace them all at once, and just equip them with core two-stage rockets."
Hearing Zhang Jun's inquiry, Yu Chengwu replied with a smile: "This is mainly because the second core cannot be recycled at one time, so we are going to mount the new engine on the second core for testing. If the test can be successful, then
We will mount it on the core first-stage rocket produced in subsequent batches and start reuse.
On the other hand, our new first-stage rockets are still alive and have considerable reserves. We cannot let them just sit and gather dust. We still have to give priority to using these existing rockets. They will not be used until they are used up.
New rocket body.
Of course, this is not absolute. If we need to transport more and heavier materials and other loads in the future, we will use a new engine and a new rocket body to enhance the rocket's carrying capacity."
"You know how to live a good life!" Zhang Jun gave a thumbs up and praised: "You look like a family member."
"Haha, I learned this from Mr. Wu and you. I didn't think so before, but as the company grows bigger and bigger, there are more and more places to spend money. I really understand the old saying, you don't know how to make money when you are not a master.
It’s expensive. Therefore, we have also put forward new requirements for ourselves and those below, that is, to live frugally, and we must spend money that should be spent, and we must not spend money that should not be spent.
Similarly, continue to strictly implement the clean, clean, simple, direct, and fresh company environment at the head office. Put an end to all formalism, extravagance, and flattery. Retain talents who are truly capable, able to do things, and willing to work hard, and eliminate them.
Those employees who have no ability, flatter others, drill holes, mess things up, and those employees who are disengaged.”
Hearing Yu Chengwu's words, Wu Hao nodded and said: "The atmosphere of our company, including the company environment, is indeed relatively relaxed, but this relaxed atmosphere and environment require systems to maintain and control. Without systems, it is impossible to maintain such an excellent environment.
the company’s internal environment.
Remember, at any time, the system is the foundation, which is the foundation of the company. If the system has no deterrent effect and no binding force, then the company will become a mess and collapse is not far away."
After saying this, Wu Hao looked at Yu Chengwu and said, "Continue."
Okay, Yu Chengwu was stunned for a moment, then nodded and continued: "Then there is a new generation of semi-solid foam propulsion fuel. Compared with the previous semi-solid foam propulsion fuel, we have upgraded it in many places.
For example, its state is more stable and can be easily stored and transported. Moreover, we have also optimized the production process, reducing its cost by 30%.
Of course, in comparison, the most important improvement of the new generation of semi-solid foam propulsion fuel is the capacity density. We have increased it by about 30%, which means that the thrust of rockets using it can be increased by 3%.
Around ten.
The Jianmu-9 heavy-lift launch vehicle, which uses a new generation of rocket engines and a new generation of semi-solid foam propulsion fuel, has a low-Earth orbit carrying capacity of up to an astonishing 100 tons, and its earth-moon transfer orbit carrying capacity
It can also reach about forty tons.
It should be said that the comprehensive carrying capacity of the Jianmu-9 heavy-lift launch vehicle, which is equipped with a new generation of rocket engines and a new generation of semi-solid foam propulsion fuel, has exceeded the carrying capacity of the basic model of the new generation of heavy-duty launch vehicles that we are developing."
At this point, Yu Chengwu paused for a moment, and then continued: "Not only that, the new generation of rocket engines and the new generation of semi-solid foam propulsion fuel technology can be devolved to Jianmu-7, Jianmu-5 and Jianmu-2.
Above, their comprehensive thrust can be greatly improved.
What's more critical is that the cost of this improvement is very low, and it can also save costs to the greatest extent. This can also make our rocket reach the world's leading level in terms of comprehensive thrust, performance reliability and economy, truly
In a sense, it has reached the forefront of the world’s aerospace technology field.”
Of course, Yu Chengwu softened his tone and continued: "Whether it is a new generation of rocket engines or a new generation of semi-solid foam propulsion fuel, they are all developed by us for the new generation of heavy-duty launch vehicles.
The carrying capacity of the new generation of heavy-duty launch vehicles using a new generation of rocket engines and a new generation of semi-solid foam propulsion fuel will be significantly improved. The carrying capacity of its basic two-stage single rocket can reach about one hundred tons.
As for the enhanced heavy-lift launch vehicle using a bundled structure, its carrying capacity can reach an astonishing 160 tons.
In this way, its carrying capacity can reach the world's leading level.
This rocket will also undertake our future tasks of transporting large components to the moon, as well as manned landings on Mars and other major tasks."
Hearing what Yu Chengwu said, Zhang Jun couldn't help but ask: "Isn't the most important thing about a rocket the engine and fuel? Now that these two problems have been solved, will the new generation launch vehicle be ready soon?"
After listening to Zhang Jun's words, Yu Chengwu couldn't help but smile and shook his head and said: "Although the heart of the rocket is the engine, the brain is the flight control system.
Moreover, the new generation of heavy-duty launch vehicles will use dozens of engines. Although the engines are all manufactured according to the same standard specifications, any industrial product has certain work differences. These work differences will lead to subtle differences in the working conditions of different engines.
difference.
How to adjust these dozens of engines to work simultaneously while eliminating the impact of engine differences is a problem we need to solve.
In addition, there is also the problem of rocket body materials. With such a huge rocket body and such a huge load, the test of rocket body materials is very strict.
Another example is the vibration generated by dozens of engines working at the same time, which is also a test for the rocket body structure. Once resonance occurs, the entire rocket body may disintegrate in the air or even explode."
