[4k Clean Audio] Starship Static Fire // A:B Comparison w/ Deluge
Вставка
- Опубліковано 13 сер 2023
- A comparison of SpaceX's Starship boosters performing static fires on the orbital launch mounts. The first one without the deluge system was performed on February 9, 2023, lighting 31 engines and lasting about 7 seconds. The static fire with the deluge was performed on August 6th, 2023 lighting 29 engines for approximately 2.7 seconds.

Those shockwaves on the slomo where awesome. they show the absolute power that is present
The water is there to absorb the sound energy not the heat
The water normally is use to absorbed the sound not the heat but (and it's a big BUT) this isn't a normal thing in any sense.
You're absolutely right. While I was watching the deluge one for the first time, I wished that the "slow mo Guys" where there with one of their super fast toys. Just think about that sequence at 1'000'000 frames per second, should be unbelievable
@@Eric-dr5bjWrong. In this scenario the sound suppression is a secondary goal.
IKR! 1:56
Starship is honestly the most exciting thing I've seen in terms of rockets in a very long time... GO STARSHIP
STARSHIP*
@@atomskate4882 ah thx
Now just to get FAA approval ....
At this point I’d be happy to see any of these next generation rockets start flying. Even with all the progress on starship I doubt it will be making frequent reliable flights to LEO in the next two years at least.
Yep we are lest than a decade to start traveling to space cheap… space tourism or breakfast in LA and brunch in Sydney… we are talking minutes not hours… or LEO factories… that is all wild.🤯
WOW didn't expect to see all those acoustic waves in the deluge slo-mo
Wonderful slow-motion, shock ways are insane ❤it
1:56 Awesome vapor compression effects.
Yeah that looked unreal, very cool
What do we learn? If it’s wet you will finish more quickly.
💦
Dirtiest scientific observation I've read in quite some time 😂
:]
😂😂
😂😅
Epic shots! Thanks alot!
Wow! That sound is impressive.
Love your vids. Thanks for all your effort!!
Love the way you can see the shockwaves propagate through the water as each set of engines fires up 1:56
I absolutely love the glitchy slowmo fog. The power of those engines is something to behold!
The side by side is great. It's crazy how white the steam is compared to the dust 😂
right, looking back it was insane launching that monster without a water deluge system😭
@@Regoflikaat least they’ll could use a flame diverter, but Elon had other plans 😂
@@RegoflikaDont have to look back. It was insane when they did it. Just look at the debris that the static fire kicked up. 🤷
Looks so much more like a regular F9 launch plume now. Way to go! 🚀
Great job team!
nice to see you get up there in the world, been here since pre-1k subs
WOW!! WAY TO GO GUYS!! Love it!
Thanks to Tim and the Cosmic Perspective team for this comparison that beautifully demonstrates how the water deluge system is basically a cleaner for the rocket plume.
Great vid ! Thank you.
Cool stuff Tim 👍🏻👍🏻
Fantastic audio!
An amazing video, thank you❤
So cool. Thanks, Tim.
awesome comparision!
Incredible footage 👏 🙌 😍
a great sign of progress!!!!
Absolutely fantastic audio and visuals.
Can't wait for a potential other, hopefully successful 33 engine static fire with a full 5 seconds durations, that will be epic to see.
can confirm
@@josephneider7332 Yeah, it was so cool!
No kidding! Too bad the FAA and Wildlife Agency are messing with Musk. I mean c'mon! For the price of each RS-25 main engine we could've bought an entire falcon heavy launch... for *each engine*. We might already have had the lunar gateway operational.
@@shift_register7431 The FAA is working with SpaceX, not against them.
The F&W however is taking its sweet, sweet time, with a possible additional delay if they feel like it, and that is frustrating.
Also, this has basically nothing to do with the RS-25 or SLS, nor Falcon Heavy, no idea why you bring it up here.
Sorry if I came off as pissed, it's not directed at you, more at the government. And also I do know that the FAA and SpX are working together, as I hear people scream that its collusion and corruption when its normal operating procedure.
I love to see an update of this If they do another full duration one.... you could compare them better that way
Just awesome!!!
Nice. Thanks
the soound is just so satisfying!
The comparison we always needed without knowing that we needed it.
It really puts perspective on the amount of dirt/dust/debris that was being thrown around by the old setup.
Finally a video on starship
😱 the pressure waves through the steam!!
Beautiful
I "watched" this hooked up to my surround sound, volume cranked up, without actually looking at the screen.....and yes there is a definite difference between the two....without the water system, there is an insane amount of crackle and sharpness from the engines and the honk on shut down....the SF WITH water, .as short as it was, the water system muffled all that sharpness .... an the slo-mo shot of the steam absorbing the shock waves....PHENOMENAL !!!! Thanks for the comparison!!!
Thank you waiting for the new vid
Very nice.
the slowmo was incredible with the deluge. Thanks EA
The condensation gasses being sucked down during the fire is amazing.
Really love that final "whooping" sound the Raptors make just before shut down. Ace
I would like to see a plot of pressure over time in the engine, the shockwaves give the appearance of high spikes rather than the smooth combustion I would expect. Very interesting footage.
So cool
2:08 I see debris, and that’s with the engines on low power. Is there anything from SpaceX about the condition of the pad? Are there any close up photos of the pad after the static fire?
I suspect they will continue to have debris until they actually do a flame diverter. Probably have to lose a few more rockets before Musk gives in though.
WOW! In the slow mo with the water you can actually see the shockwave of the engines firing up as it goes through the vapor cloud! Very cool….or HOT!
Those clouds of steam from the deluged fire look so much more wholesome than the volcanic smoke from the unmitigated fire.
Just saw you made the DEARMOON crew. Congratulations! Lots of hard work on your part to make that possible.
Like what? Being the biggest Elon stan on the planet😂
The deluge system is amazing! I can’t wait to see what Happens when the raptors ignite at full power again.
The shockwaves ripping through the steam was awesome
The whiter the clouds, the better the outcome. Thank's ❤
That was quick but cool
I'm rooting for Starship if for no other reason than it's supposed to be providing lunar landers for Artemis. Also, I really want to see Tim go around the moon.
Una delicia... tus videos estan en otro nivel.
Loving the new Fountain of Thrust 🚀
Did you boost the bass on the slow motion test? My subwoofers had everything on the walls rattling like crazy 😅
Massive difference!
The difference in sound is very interesting
Gives a whole new meaning to “flash boiler”. 😏
Love the side by side. Quite the difference. Maybe next launch Tim's gear will get a steam bath instead of dirt shower
You need the suppression system to cut down the sound, shock wave and control the blast. And it's great for clearing out your sinuses!
Hi Tim, do you have comparison of sound strength in DB in both cases?
Have to be careful with those kinds of comparisons. Only makes sense is the data is recorded from the same location and with the same setup both times, since I believe acoustic energy dissipates at a rate of roughly 1/(distance ^ 4). Any deviations would render the subsequent sbs comparison null and void. Awesome thought though, and given how neurotic these types of journalistic endeavors usually are, it wouldn't surprise me if the setups WERE in fact identical, so who knows? Only the TIM knows.
So very much tamed with the steam production - this works very well! Spacex should be v happy!
@2:04 onwards look at the debris flying. Did the deluge really work?
Also flattened the fence.
Yes, that’s just debris not concrete. And the fence is temporarily, it’s going to crumble, there’s no need for a massive wall
Question? Why hot stage when u already have all the hardware onboard for the boost back burn???
Cool
There are still bits and pieces flying around even with the deluge system. Really curious what an actual launch will look like in comparison.
1:57 i repit this moment Of the video 100 Time just to hear an see how powerfull the booster 😍
Neat how long it takes for the deluge system to stop oscillating. I'm sure that could be improved but 5 - 10 seconds seems fine enough.
Why is something so dangerous so beautfiul? Almost hypnotic to watch the Steam bloom
Would it be possible for mechazila to host and manage multiple launch pads ?
How long does it take to refill?
I’m sure he mentioned it somewhere in his videos but missed it: what’s the benefits of a deluge system? Thanks
I think the deluge system needs more pressure. In the slo-mo, the thrust cuts off, then it takes a second or so and only then you start seeing water fountains again. That looks to me like the overpressure from the engines basically blew the water back into the deluge system, causing the pad to fall dry.
I noticed the same thing. The water outlets may have to be moved up to the booster mounting ring and angled downward
@@johnbowman476 possibly. Otherwise, they'll have to increase the pressure to 350 bar or so... I think they need a pressure sensor in the center of the pad and check what they actually need. I suspect it's much more than the pressure from a single raptor, since the outer engines already create a high pressure zone and the exhaust from the inner ones can't escape...
Eagerly waiting for your video on Chandrayaan-3
The shockeave going through the steam js absolutely increafible to watch 1:56
Incredible, even.
If they could increase the water pressure to something extreme, it could help push the booster off the pad
Deluge hardly ruffled the grass, barely an inconvenience.
I am definitely Team Full Pressure Deluge.
So Tim, get those T-shirts into the merchandise shop!
2:02 holy wow those shockwaves were unexpected
Surprising to see water splashing the outer engines compared to the deluge test. I wonder if they added pressure or an unintended result of priming the pipes
Most likely a result of the deluge test they did.
Aide from the obvious increase in steam and water, the biggest change I noticed was that the fires stopped when the engines stopped... that right there seems like a HUGE win!
There's also a lot less dirt in the steam compared to the dust cloud. Another win.
what were the decibels for each test?
The thing that really hit me hard when the dry pad launch was clearly a no-go, was the prospect of the rocket using the same stage to lift off from the moon without something keeping regolith from being kicked back up at the engines. single-stage landing and liftoff is going to require moon-side equipment or something like the Apollo lander lower section to be that regolith protection for liftoff. more work in the end for a moon mission or other planet mission. Even getting into the infinite-fuel realms of SciFi, makes the landing gear and underside of the USCSS Nostromo being so robust, a requirement, unlike some flimsy struts and gear in other SciFi shows. Also if you look at the Nostromo, the engines point outward to push the stuff away from the ship when firing, which also makes them just a bit more inefficient, and that gets back to the "infinite-fuel realms" issues.
I could still see some things getting blown out with the deluge but not as much.
Anyone know if they have DB sensors around the platform, and complex in general?
Would love to data on acoustics pre and post bidet
"burst discs" in the 'showerplate' maybe?
Would be really hard to measure, you might place a sensor in one spot which just happens to stand in a peak or trough of a wave
Why no footage of what axial damage has happened or been avoided?
So is it economically feasible if we use starship as the most expensive garbage truck for our growing microplastics problem?
Kerbal Space Program in real life hits different
GO STARSHIP! GO SUPER HEAVY!
Wow you can see shock wave in the water
@2:01 ❤
I was 8 years old when Apollo landed on the moon. It was the most amazing thing I have ever seen and will never forget the experience. At the time I was sure that a human Mars mission would be right around the corner......but....no one seemed interested for years until all the amazing aerospace programs in the last few years...Starship is so cool....So I'm 62, what are my chances of living to see someone land on Mars?
Seems like they started the water a second or so too soon and some was wasted having already fallen to the ground before the flame front blasted forth.
Since they need basically 10 seconds of water flow for a launch either they need more water (tanks) or adjust the timing
I believe they just added a 3rd tank.
So, how high up would the launch tower need to be for this to not be an issue? Can't you just make the launch tower tall enough that the flames and force dissipate before hitting the ground?
Not really.
i think the shockwaves show the staggered start of the engines. two waves are clearly to see.
"I'm getting closer to my home."
🤖🧡
Great pics. Wasn’t the thrust and especially the firing time WAY MORE on the “no deluge” situation?
Come on man😱
You could steam a lot of crab, shrimp, etc. with a setup like that.
Shame there wasn't a sound pressure level meter on both.
And/Or frequency visualizer. But not sure either would really tell anything. Even with the deluge I'm guessing any mic would be saturated
@@Emu0181 you could record several channels where each mic is attenuated 20, 50, 100 dB
does anyone know why the starship did not separate?
SpaceX is the Future 🔥
Will it launch this year
