Vol 2 Chapter 1673: Can this be called a "cottage"?

Regarding the maiden flight of the Jianmu-7 rocket, coupled with this intelligent lunar patrol rover, both major media and ordinary people are very concerned about this.

Many media and bloggers also made a special trip to the South China Sea Space Launch Site to prepare for live broadcast. Even the central station has set up a machine and is ready to broadcast the whole process.

Related community forum posts on the Internet and various exchange groups are all about the first flight of the Jianmu-7 rocket and this intelligent lunar patrol rover.

That's amazing. It's only a few years now, and Haoyu Technology is about to go to the moon.

Indeed, Haoyu Technology has developed very rapidly in the aerospace field in the past few years. From the initial launch of small rockets, it has now been able to launch medium-sized launch vehicles. The 18-ton low-Earth orbit carrying capacity can be said to have been thrown out of us and other countries outside Laomi.

It cannot be said that the European launch vehicle technology is also very good. However, with the relevant parameters of the current Jianmu-7 rocket, it can be considered to be on par with the latest European launch vehicle in terms of carrying capacity. Of course, the Jianmu-7 rocket has a unique advantage, that is, its core-level rocket and fairing can be recycled, which can greatly reduce launch costs every day, which is unmatched by most rockets. of.

Speaking of rocket recoverable technology, we have to take out the Falcon rocket for comparison. In terms of specific parameters, Jianmu-7 is still slightly behind the Falcon Rocket.

No way, Musk has the resources and there are so many choices. As for Wu Hao and the others, they all started from scratch, and they had to do everything by themselves. It is already very remarkable that they can develop this way within a few years.

After all, it is not a copy of the cottage. Look at the current Jianmu No. 7, which is simply a replica of the Falcon Rocket. He Wu Hao did this, isn't it a bit unnatural?

What is not authentic, did Wu Hao stole or snatched Musk's technology? This is called reasonable borrowing, and drawing on the excellent experience of the predecessors to make use of it. This is basically the case for all companies.

That's right, tens of thousands of links and related technologies have been designed in the development of the rocket. You think anyone can copy it. People's three pots, the strength of the whole country, did not see a copy of the results.

This person simply doesn't understand what copycat imitation is. Copycats take other people's products, copy and imitate them one by one, and then modify them. Falcon Rocket, steal it from me and let Wu Hao copy it.

If he can steal one back, he doesn't need to give it to Haoyu Technology and directly hand it over to the country, he is a great achievement, and he is the person who moved the year.

Although the Jianmu 7 rocket and the Falcon rocket are very similar in appearance and form, they are actually very different. The Jianmu series of rockets have always used the semi-solid foamed propellant originally created by Haoyu Technology. It is said that this semi-solid foamed propellant fuel has a higher energy density than traditional liquid oxygen kerosene and can generate greater thrust. Therefore, the reminders of Jianmu series rockets are relatively small, and the relative carrying capacity is relatively large. At present, this semi-solid foamed propellant fuel can be said to be of the world's leading level.

I have also heard of this semi-solid foamed propellant. It is said that because it is in a semi-solid foamed state, it can be stored for a long time. It can be stored for several months or several years. I heard that the official related rockets are already testing this semi-solid foamed propellant fuel, and the evaluation is very high.

Not only the launch vehicle, but I heard that Dongwu may also use this semi-solid foamed propellant. In this way, the preparation time before the East Five launch can be greatly reduced, and the fuel refueling process can be omitted directly. The East Five can fully adopt the combat readiness mode. Each East Five can be filled with semi-solid foamed propellant fuel for several months for combat readiness and then be replaced on duty.

Haha, these are all speculations from the outside world, but it is the most important weapon of the country, how can it let us know the details.

Not to mention these, let alone the group is gone.

Judging from news reports, this time the Jianmu 7's first flight is very difficult. One is the new rocket, which uses a lot of new technology, has not been tested in actual combat, and its performance is unknown. Secondly, the South China Sea space launch site was chosen this time. Compared with inland launch sites, coastal launch sites have pros and cons. The biggest drawback is the impact of sea salt on the precision components of the rocket. The deep moist sea breeze mixed with salt-containing water vapor will enter the rocket, severely corroding the precision parts and electronic components of the rocket. There were rockets before, and because of this reason, they failed to launch.

More than that, this time the mission is also very difficult. The load will be accurately sent to the Earth-Moon transfer orbit, and the precision control is very strict. Although the entire process was carried out by the South China Sea Space Launch Site, it also tested the performance of the rocket.

You are talking about the launch phase and the landing phase. This time the ocean rocket landing platform is used. To put it bluntly, it means landing on a ship. The ocean is rough, and how to stabilize the platform and accurately receive the core-level rocket that landed and landed is also more stringent in terms of technology. In this regard, the official does not have much experience, and everything has to be done by the scientific research team.

Speaking of the rocket's recoverable technology, Haoyu Technology's performance in this aspect is indeed very eye-catching. Except that the original Jianmu-1 rocket is not recyclable~www.readwn.com~ The core stage and fairing of the next few rockets can be recovered, which can be described as a stingy to the extreme.

No way, private commercial rocket companies have to rely on strength if they want to get orders, and sophistication is not good at all. Moreover, Wu Hao and the others are facing aerospace technology, so they must increase the competitiveness of their products. Only in this way can they defeat their powerful opponents. Among all the performances of launch vehicles, the cost of delivery has always been a concern for all customers. In the past few years, Haoyu Technology has taken advantage of the ultra-low launch cost and has just grabbed a lot of orders from the aerospace technology.

This aspect is indeed very good. I heard that Haoyu Technology has reduced the cost of satellite near-Earth launch to 10,000 per kilogram.

Now some domestic commercial satellite launch missions have basically been rounded up by Haoyu Aerospace. In addition to commercial satellite accidents, some official satellites have also begun to use Haoyu Aerospace's rockets. There is no way, the cost advantage of launch is here, but they do not weigh the pros and cons.

Aerospace science and technology is indeed relatively rigid and rigid, and it is a common problem with Chinese-style enterprises. In this regard, private enterprises are far from flexible. Therefore, for this phenomenon, I am happy to see it happen. It is necessary to have such a fierce catfish in, so as to stimulate the healthy and rapid development of the aerospace technology industry.
