10-kilometre VTVL test

- Опубликовано: 28 сен 2024
- The China Aerospace Science and Technology Corporation (CASC) conducted a successful vertical takeoff, vertical landing (VTVL) test at the Jiuquan Satellite Launch Center, China, on 23 June 2024, at about 05:00 UTC (13:00 local time). The 3.8 m diameter test launch vehicle is equipped with three LongYun 70 reusable liquid oxygen/liquid methane engines (LY-70, ground thrust 70 ton). The test lasted for about six minutes, achieving an altitude of about 12 kilometres. According to official sources, a 75-kilometre VTVL test is scheduled by the end of the year and the first flight of a 4 m diameter reusable launch vehicle is expected in 2025.

It's surprising that SAST did the first 10 km VTVL test among Chinese space companies, everyone thought Landspace could be the first but they postponed the test to July.
Yeah, it's really weird. Didn't even hear about them before this.
I imagine with Chinese reusable rockets, it will be like with the EV space, where there will be extreme competition between a bunch of companies.
@@nicolamastascusa8173You're right. Besides state-owned aerospace enterprises, China has more than a dozen private aerospace companies, seven or eight of which have already achieved commercial launches. Nearly all of them have plans to develop reusable rockets. Among them, Landspace and iSpace (Interstellar Glory) are developing the fastest and are expected to achieve their first reusable launch within the next two to three years.
It's a fully state owned company. They do work on developing the technology but don't show them to public. They restrict themselves to a strict schedule which is already set for multiple years and won't deviate from it even when they are capable today. They have a schedule to send it to orbit next year (2025) and the next one in 2026.
Very unexpected right? Who would think the national team is suddenly ahead of veryone now.

Great achievement!
Congratulations! More awesome spacecraft for humanity please.
很高兴这么快就又看到国家队的可复用火箭有了新的进展，但这个用的是民营公司九州云箭的龙云（LY-70）液氧甲烷发动机，海平面70吨推力，大约是0.8个Merlin。

Now, that's a cool looking rocket.
Wow, CN good job!
Nicely done! Go China.
CATCHING ON ....FAST
以前不是说，落地要采用网状结构吗，怎么还是用支架？

有两套方案的
多套方案不行啊？嗯？
The landing suspension has been cut off. The real suspension is longer than the one in this video
You probably mean "hover". As the test was 6 minutes and this video barely contains one minute of footage, it's obvious that it has been cut.
@@SciNewsRo yes, I meant it.
Where did you get the video without watermarks and subtitles?I am disillusioned with the media in our country, the video editing is terrible, the filming techniques are terrible, and the propaganda is terrible
这个好像就是央视发的那个视频片段截取的吧，还有蓝星空间发的图，镜头拍摄都一样，他去水印放大处理了，修补了画质
@@MurmureL-oy3wl 真操蛋，也不多给几个机位，就算是出于科研目的也应该拍些高清素材啊 做好宣传可以提升国家形象
Based Chinese citizen.
...the chinese don't give a damn what others like you think
..lol ...😂😂😂😂😂
国家队没有宣传的动力。 个人公司才有宣传的动力，能融资，个人公司肯定会按的到处都是摄像头
I hope for more footage this is historic test😊

@@SciNewsRo oh wow 😲 thanks Sci News
only historic for China.
Cool!
Now make it suicide burn! Hovering is great for landing on unprepared destinations though - congrats!
Why do you make suicide burn when you don't have to. They call it "suicide" burn for reasons.
4,000 meters higher than Mount Everest. Reminds me of the starship tests a few years ago.
No grid fins?
Yes,so its more hard to control
Nicely done, but can you scale up to the size of, say - Starship?
Now, that would be REALLY impressive...
SAST did have a plan for a 10-meter diameter rocket, although it is unlikely to be realized in my opinion. In 2022, SAST published a paper envisioning a series of reusable rockets powered by liquid oxygen and methane, with diameters ranging from 3.35 meters to 10 meters.
Spacex didn't start with starship... btw they exploded a lot of boosters, this is definitely a safer approach
You can't compare CASC with Starship, CASC is a company owned by the Chinese state with the support of state resources with a GDP of 18,5 trillion dollars😂
