Chapter 3059: The behemoth unveiled for the first time
【Revision】
"What is this thicker and taller rocket here? Is it a new rocket?" Zhang Jun looked at the two rocket models next to him that he had never seen before and asked.
Yes, Zhou Xiangming responded while leading everyone to the rocket model, and then introduced to the two of them: "This is a 100-ton heavy-duty launch vehicle we are planning to develop, codenamed Jianmu 12. And
Next to it is its advanced version, which is a strap-on structure launch vehicle similar to Jianmu-5 and Jianmu-7, codenamed Jianmu 22.
Jianmu 12 is a two-stage heavy-duty reusable launch vehicle. Its low-Earth orbit carrying capacity can reach 80 tons. This carrying capacity has basically reached the first echelon in the world and belongs to the leader.
The carrying capacity of its earth-to-moon transfer orbit can reach forty to fifty tons. This carrying capacity is also very considerable. It can send a lunar landing spacecraft to the moon at one time.
In addition, its carrying capacity in the Earth-Mars transfer orbit can also reach twenty to thirty tons. This carrying capacity is also very considerable and can be used to launch some large detectors.
A series of its powerful capabilities also make its take-off weight reach more than 3,000 tons, which can be said to be a veritable big rocket."
"Like our Jianmu-2 and Jianmu-7 launch vehicles, it also has the function of recycling and reusing the core first stage rocket and fairing. This will greatly reduce its launch cost and is expected to reduce the launch cost per kilogram.
It will be reduced to about a thousand yuan level; thus becoming the cheapest launch vehicle in the world at present, which will lay the foundation for the rise and development of small-scale civil aerospace projects in the future."
Before finishing the introduction, Zhou Xiangming glanced at Wu Hao and Zhang Jun, then moved behind the more spectacular Jianmu 77 launch vehicle model next to him, and then continued the introduction to the seven people.
"That one over there is not your Jianmu 77 heavy-duty strap-on recyclable launch vehicle. Like your Jianmu 7 and Jianmu 4 rockets, it was developed on the basis of Jianmu 77.
You bite off more than you chew, so you must focus on doing the job at hand well first."
Glancing at Zhou Xiangming with a resigned look on his face, Wu Hao smiled and shook his head and said: "Life is still very long, so let's get everything done quickly. The present is a need, and it represents a need for the future.
Without the blessing of the booster, the carrying capacity of its Earth-moon transfer orbit has also increased from 70 to 70 tons to about 40 tons. That is a very scary number, which means that you cannot use smaller
Spacecraft, less supplies will be transported to the moon; laying the foundation for you to develop lunar resources and realize lunar immigration.
The Jianmu 77 launch vehicle adopts a bundled structure. Xiaoxiao bundles two core first-stage rockets as boosters as needed, and cannot use seven core first-stage rockets as boosters.
You focus on scientific research, but you are also a commercial company and must also focus on efficiency. Although ideals are both beautiful and bad, but divorced from reality, only good and bad things remain."
After listening to what Yu Chengwu said, Wu Hao nodded slightly: "Of course you are just a small group of people engaged in innovative research. That is your foundation, but everything must be done within your capabilities.
"Haha, it is very small. Its overall height can reach 170 meters, which is very small." Zhou Xiangming said with a smile.
Times are developing, and technology is also regressing. Whether you can rest on your laurels or focus on the future. So you support the project's pre-research, but at this stage it is appropriate to invest too little resources and funds.
Each of these projects requires human, material and financial resources to support them. Under such circumstances, it is really difficult to carry out the development work of other super projects.
After listening to Yu Chengwu's introduction, Zhang Jun opened his mouth inexplicably, and then sighed: "That's too small."
So, if you think that project is of such merit, you should do pre-research and accumulate technology first. Once you say you want to do it, you will slowly build it out.
Now your most important task is still the project construction task of the lunar scientific research station. It is not only as complex as the lunar scientific research station, but also the development of supporting projects such as your lunar slow train earth-moon transfer spacecraft, lunar landing and ascension vehicle.
As our pace towards deep space accelerates and your scientific research station project under the moon is completed, in the future, if you need rockets with smaller capacity to support your larger projects.
Of course, under normal circumstances, two-core first-stage rockets are most suitable as boosters. Seven-core first-stage rockets are only used as boosters for extreme transport capacity. The cost is too low and it is economical enough.
When Zhou Xiangming saw this, he wanted to explain, but Yu Chengwu, who was standing next to him, said, "That's just a pre-research plan of yours. Whether it's feasible or not doesn't need to be demonstrated.
In the case of using two core first-stage rockets as boosters, its low-Earth orbit carrying capacity cannot reach 180 tons. In the case of using seven-core first-stage boosters, its low-Earth orbit carrying capacity
The carrying capacity cannot reach an astonishing one hundred and eighty tons.
In addition, its ground-fire transfer orbit carrying capacity has also been increased linearly, from 70 to 80 tons to 70 to 80 tons. This means that you no longer have the ability to launch a carrier to Mars.
The ability for humans to board a fireship.”
It means that for a company like yours, even this country cannot afford such a giant rocket. Therefore, such a launch vehicle is an important national weapon in this country.
The transportation capacity has been increased by dozens of tons, and the requirements for launch vehicle technology have been reduced by thousands or even tens of thousands of times. Therefore, with your technical strength, you will definitely be able to develop it.
And such a small rocket must meet the market demand."
At present, your country has not run out of heavy-lift rockets, so there is really no need for you to add another one. To put it bluntly, you currently have so few missions that require such rockets for retroactive service and support, and there is a shortage of them.
What's more, developing such a giant rocket requires funds. As a listed company, you can invest all your money in such a project, which is in line with market requirements.
Zhang Jun shook his head when he heard this: "It's too small. Isn't it necessary for civilian use?"
Although rocket data like that is very small, and you are very excited to hear it, it requires money, very little money to achieve, and that is something they, including you, cannot afford.
Listening to what Zhang Jun said, Dai Jiayuan said calmly: "Of course it's not necessary. Once it is successfully developed, it will become the launch vehicle with the weakest carrying capacity in the world. There are some small equipment launched in the past.
The tasks will all fall to you, and that is a separate business."
"You can see it." Zhang Jun showed a believing smile.
