Wu Hao nodded, then looked at Yu Chengwu and asked, "Tell me about the engine and the new generation of semi-solid foam propulsion fuel used in this Jianmu-9 heavy-lift launch vehicle."
Upon hearing Wu Hao's inquiry, Yu Chengwu immediately introduced: "Okay, this time we used a new rocket engine and a new generation of rocket engines on the core and second-stage body of this Jianmu-9 heavy-lift launch vehicle. Semi-solid foamed propellant fuel.
The first is a new generation of rocket engines. Compared with the previous two generations of engines, the performance of the new generation of engines is stronger. Its thrust can be increased by about 18% at the same mass.
This means that if our entire Jianmu-9 heavy-lift launch vehicle uses a new generation of rocket engines for the core first-stage and second-stage rocket bodies and boosters, it will increase our carrying capacity by 20%. .
In other words, we will increase the Jianmu-9 heavy-lift launch vehicle’s low-Earth orbit carrying capacity to an astonishing 75 tons, and the Earth-to-Moon transfer orbit carrying capacity to about 30 tons.
Not only that, we have also improved the reliability of the new generation engine, reducing its failure rate by about 50% compared to the previous one, which is average, making its performance safer and more reliable.
Furthermore, we have extended the overall life of the new generation engine. Our original rocket engine could probably perform fifteen to twenty rocket launch and recovery missions.
Of course, this is theoretical. In actual use, excluding safety redundancy, our maximum number of uses for the first-level rocket body is about sixteen times, which has basically reached the replacement and elimination standards.
As for the new generation of rocket engines, its theoretical service life can reach about thirty times, which means that its actual safe use times can reach more than twenty times. "
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 will be confident that every kilogram of the rocket will be used. 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%. "
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 rocket is still alive and its reserves are quite considerable. We can't let them just sit there and collect dust. We still have to give priority to using these existing rockets. The new rocket body will not be used until it is used up.
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. "
Will 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 what we should spend, and never say anything about what we should not spend.
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. Keep those who are truly capable, capable of doing things, and willing to work hard, and eliminate those employees who are incapable, flattering, boring, messy, and those who quit. "
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 it. 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 stored and transported conveniently. And 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 reached and is close to the carrying capacity of the basic type of the new generation of heavy-duty launch vehicles 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.
