Vol 2 Chapter 1224: Cross the river by touching the "stones"
Wu Hao is telling the truth, they are a commercial company, a private enterprise, and what they seek is nothing more than profit. If the R&D investment is too large to make ends meet, then what investment value does such a project have.
And this recyclable technology itself is to further reduce the launch price of the rocket. If the R&D cost is too high, and the cost per launch is too high, then there is no practical significance, at least for them.
Hearing what he said, Chen Guangping’s laughter came on the phone immediately: “Hehe, it’s great for you to think so and target it. I’m also worried that you will be blinded by the little achievements in front of you.
There were a lot of outstanding young people in the past. They were so proud of their achievements, but they all disappeared one by one in the end. "
Speaking of this, Chen Guangping smiled and asked: "In addition to this launch mission, I remember you still have several projects, and the progress is also very good. What's the matter, do you want to hide it?"
Ha ha, Wu Hao chuckled lightly and said, "Yes, it seems that I can't bring out something today.
Well, first of all, let me report to you about our field of rocket technology.
At present, we have a total of two research projects in the field of rocket technology research and development, and both have achieved good success.
They are the Jianmu No. 5 medium-sized bundled launch vehicle, and the Jianmu No. 7 high-performance retractable medium-sized rocket. "
Jianmu No. 5, Jianmu No. 7, medium-sized rocket? Chen Guangping couldn't help but question.
Ha ha, yes. Wu Hao nodded and said, "The first is the Jianmu 5 medium-sized bundled launch vehicle. Its overall structure is similar to the Falcon 9 heavy rocket.
Its main structure is similar to the Jianmu-2 rocket, and the biggest difference is that we have added two booster rockets to this Jianmu-5 rocket.
actually means to tie the first-stage rocket bodies of two Jianmu-2 rockets to the Jianmu-5 rocket to act as booster rockets.
Thereby increasing the thrust of the rocket, so that the carrying capacity of this Jianmu 5 rocket has been further improved.
At present, the low-Earth orbit carrying capacity of our Jianmu-2 modified rocket is about six tons, and this Jianmu-5 bundled rocket can carry about 15 tons. As for the geosynchronous transfer orbit, it can grow from the current three tons to about eight tons.
Such a carrying capacity is sufficient to undertake some heavy-load launch tasks. For example, some heavy satellites, heavy spacecraft, and cargo spacecraft, etc. It can even undertake some lunar exploration and deep space exploration missions, and its carrying capacity is still very impressive.
Of course, the biggest advantage of this Jianmu 5 bundled medium-sized launch vehicle is its low launch cost.
And this is the biggest advantage or feature of this Jianmu 5 rocket, that is, the rocket's first-stage body and two booster rockets can be recovered. The rocket fairing can also be recovered, so that the rocket's single launch cost can be greatly reduced.
This is difficult to compare with traditional launch vehicles. Its launch cost may only be about 60% of that of traditional launch vehicles, which can be said to be very cheap.
Three first-level rockets were bundled, and then three rockets landed and recovered together. It seems that you have ‘learned’ Musk’s rocket technology very thoroughly. "Chen Guangping joked on the phone.
Where, you laughed, we also crossed the river by feeling the stones. Wu Hao smiled and said.
Hahahaha, it's a good one to cross the river by touching the "stone", but I don't know how this "stone" will feel after seeing your Jianmu-5 rocket. Chen Guangping sold well.
Wu Hao also smiled and said, "It doesn't matter, he can't come to China for our troubles anyway, and I'm afraid of what he will do."
OK! Chen Guangping praised, and then continued: "Indeed, compared to light rockets, medium and medium-sized rockets with large capacity are the launch vehicles that are urgently needed in our country's aerospace field and even the world's aerospace field.
In particular, this kind of low-cost commercial launch vehicle with large carrying capacity has indeed filled the gaps and gaps in the current commercial launch vehicle market. Your positioning is very accurate and your vision is very poisonous.
More importantly, the R&D investment of this rocket is very limited. It is completely an improvement and upgrade of existing technology, and it makes full use of existing technological advantages. This is commendable.
I believe that when your Jianmu 5 bundled medium-sized launch vehicle is put on the market, it will inevitably bring considerable pressure to the Aerospace Industry Corporation.
It’s good to be like this, when there is pressure, there is motivation. It is also time for them to feel a sense of crisis, so that they can be forced to promote their development and innovation.
Then there is another rocket, which is the Jianmu 7 you named it? "
Hearing Chen Guangping’s interested tone, Wu Hao said with a smile: "Jianmu No.7, like Jianmu No.2, is also a single recyclable launch vehicle.
From this point of view, it can be seen as an enlarged version of the Jianmu-2 rocket. Its rocket body has a diameter of 3.8 meters, a height of 59 meters, and a takeoff mass of 450 tons.
Compared with the increase in volume and weight, it also has a strong carrying capacity. Its low-Earth orbit carrying capacity can reach about 18 tons, while the carrying capacity of the geosynchronous transfer orbit can reach about eight tons. Even the carrying capacity of the distant Mars transfer orbit can reach about four tons.
Such a large carrying capacity is also sufficient for it to undertake more, larger, and more complex launch tasks. "
Hearing Wu Hao's introduction, Chen Guangping couldn't help but exclaimed: "Good guy, you are a fake Falcon rocket, and the data performance is too close."
Regarding Chen Guangping’s words, Wu Hao did not deny, but said with a smile: “From the overall performance point of view, we are not as good as Falcon rockets. However, we have a huge advantage, that is, our rocket launch costs are higher than theirs. Much lower.
So our international commercial launch price is much lower than theirs. "
Hearing what he said, Chen Guangping was silent for a while, then comforted on the phone: "Don't worry, as long as we have good things, we don't want to find customers.
In the future, the aerospace field will no longer be the patent of developed countries, and will gradually spread to other countries. The entry of these countries also means that it has brought new market opportunities.
So as long as we grasp this point, I believe that we will definitely be able to create a world in the national commercial aerospace field. "
Hearing Chen Guangping’s comfort, Wu Hao’s face showed a smile. For some reasons, we have always been rejected by certain ‘rogues’ or even suppressed by blockades in the field of space technology. Therefore, in the field of national commercial space cooperation, progress has not been very smooth.
Chen Guangping thought Wu Hao was frustrated by this, so he couldn't help comforting him out loud and cost him a pie.
