We are Stoke Space 

what a small world

You could say that you are... stoked for them.

To be honest I don't know how all these companies plan to compete with SpaceX in this niche market. Even SpaceX suffers from lack of orders. That's why Elon decided to create Starlink.

Hey Jared, howabout a video on how the hadron super collider works?

can you do a video on stoke space? it seems really cool and interesting.

Was about to say that, also really cool concept

kevin you probably live in a home depot

Hey alligator - StarshipLunar

IT’S YOU FUCK, YOU GOT HERE TOO

Yeah the voice over might be the sane guy.

I intended the same pun.

Heh. I see what you did there. Clever!

I'm not sure I love that at all. Tryhard advertising with played out rhetoric and generic thumping music is exhausting and everywhere already.

@@BlueZirnitra Lmao thumping music? Seriously? It's an announcement of a new space company. You're literally complaining about nothing 🙄

@@martyn975 And you're literally complaining about me complaining about nothing. Good thing opinions are free.

@@BlueZirnitra nice comeback

That is literally the point of this comment. The arrival of a new GMC Truck and a new 30 rocket system prompt the same music and style. It's a sign of the times numb head.

Not really a reason to get into space nowadays if you don't go for reusability. Launch & stage vehicles are just too expensive to not try to save them. It only works for the juggernauts because they're either 1) government funded or 2) the government.

yes im early so

@@wesplybon9510 The government is less focused on space compared to the space race

​@@wesplybon9510 Rocket Lab?

Yes, yes, but, I have yet to see a first working stage, let alone a second. I mean, blue Origin is yet to fly, space x is struggling with super heavy, ULA with Vulcan, and small firms like relativity space finding out getting to spa d is more difficult than three d printing...these guys are saying it's easy.. They might be underestimating the challenge.

Of course it is. Funding is drying up in this market.

@@jay-em why? I thought space market was to be boomed...

@@jay-em no it's not, the aerospace industry is booming

They're doing engine testing so I assume that they're making good progress

It is

NASA a publicly funded space program only took 9 years to get to the moon using 60s tech so why is it taking private industry so long just to reach low earth orbit

The race being led by private companies is precisely what worries me.

History is being made.

What other companies are there?

@@CAC1Aimer spacex, virgin air, astra, rocketlab, firefly, etc

Oh Hey Jesus, Glad to see you doing well

Happy early Birthday!

Jesus still here appreciating Human's work on exploring space... amen

lol

I suppose you are amused by the efforts your creations make to escape their comfortable pris- I mean home you handmade for them

Looks like I'm #737. My favorite jet until recently. Cool number anyhow. I hadn't thought to check until I saw your #22. Too bad I didn't get #42.

#5.24K

Looks like im #5730

basically, they're doing what SpaceX does -_- no reason for them to win

@@expensivecats well it is better for there to be competition than just 1 company with the capability of launching reusable rockets, there is also no need for corporation bias like that as they don’t care about you

How could you possibly lose motivation when your 2nd stage plume looks that cool?

​@@tomoliveri8168 yeah! ITS A FREAKING AEROSPIKE! ITS A HOLY GRAIL OF HOLY GRAILS OF ROCKETS!

I would call it a "virtual aerospike" - a similar effect but without the spike itself .

@@medivalone The aerospike doesn't really require the spike, but your point still stands. Part of the heatshield might have a profile similar to that on a truncated aerospike, and the rest of the spike is generated by pumping gas out through the middle of the heatshield, i.e. the same vent used to provide active heatshielding.

@@medivalone I'm guessing that they can also achieve the 'optimal spike' by varying the gas flow rate according the thrust of the small engines along the circumference.

yeah, the aerospike needs to handle extreme temperatures anyway, so it make a lot of sense to use it as the heat shield although i'm not sure how their metallic heat shield is gonna work

Aerospike has its benefits if used in the atmosphere, hence the name. What's the point of having it for the 2nd stage?

I highly doubt they are going to end up with a metallic heatshield. SpaceX's Starship was originally shown to not have a ceramic tile heatshield either, but now it does. Metal warps under those high temps and will begin to fracture. A metal heatshield isn't indestructible, and it's ultimately just going to be more expensive.

@@randompersonoftheinternet8012 Agree on those points. If anyone was to try it, it would be SpaceX. There is a reason why it was abandoned. Maybe stoke space made a breakthrough. We never know till we see it. Let's see..

@@IsMaski they haven’t even finished the first part of their program: the propulsion system for the second stage. As far as I can tell from the video all they’ve done is plumbed up the ring of combustion chambers. Time will tell, but don’t get your hopes up

@@randompersonoftheinternet8012 so there are some significant differences in the designs of starships heat shield and stokes heat shield. The primary difference is that Stokes plans on using regenerative cooling for the heat shield. They have channels within the heat shield through which they will be running the LH2 propellant, the absorbed heat will actually be used to the power the turbo pumps for the engine. This differs significantly from the original starship design which planned on trying to use a diffusive active cooling where the methane fuel would diffuse through the surface and create a film cooling effect. This had significant problems as they couldn't achieve uniform diffusion rates across the entire surface which led to hotspots. Some other differences are the significant size and shape difference. I believe the very large surface area of Starship is one reason they couldn't do the channel cooling, and ultimately why the diffusive film cooling didn't work either. Also the use of methane also makes the channel cooling for starship impractical due to its heat capacity compared with LH2. Additionally Starship will be reentering from much much higher orbits, significantly increasing the thermal load on the heat shield.

@@Ender240sxS13 My point is that they are subject to their solutions simply not working, just like spaceX. Also, the size and shape are a significant difference, but I also see it to be a problem. The 3d render showed the heat shield on the bottom of the payload capsule, which doesn’t have as large of a drag cross section as opposed to re-entering on it’s side. This just means the heatshield will have to sustain more heat, and the burners for slowing the landing will have to do more work. I mean these potential issues would be a huge thing to overcome, and until they actually test this “groundbreaking heat shield technology,” a 3d render is just an imaginative vision.

SpaceX is for incels.

Always wanted to be an AE, how are you enjoying the field?

I wonder if that fits on the top of a Falcon 9 booster...

i agree

@@briankeeley6464 Would be sick

They need an expendable bell system that detaches after deployment.

@@n1k0n_ Idk. Aren't aerospikes very similar to bell nozzle's performance wise? I'd just guess it's hard to do. But i don't know :)

Having 10 engines is a big engine failure risk.

@@pickleboi8002 Pretty sure it was 20, and I'd disagree about it being a big risk. There may be a higher chance of failure, but in return any failure is much less damaging. They could potentially lose 2 or so (and shut off their opposing engines) and still reach orbit and maybe even deorbit, allowing checkouts after partial mission failure.

@@DJ_Level_3 well, you got 20 as much chance of engine failure and the engines produce less thrust.

My first thought, even the shape of the 2nd stage resembles some vehicle concepts from the 1960/70s by Philip DeBono.

Yeah it’s not an aerospike it’s a cluster of conventional small thruster bells. I believe the aerospike looking plume is probably a fair representation of what would happen if all the plumes intersected in space. I don’t believe it would provide any aerospike affect. I actually don’t think that’s a bad thing, aerospikes haven’t lived up to the hype

Also an aerospike on the 2nd stage makes no sense because by the time it fires up you've already left earths atmosphere.

@@sose6255 Space elevator, but that’s still science fiction for at least 50-100 years if not longer. One day… if we make it long enough that is

Have you heard of Starship? Space X has been working on 2nd stage recovery for years now. The only thing these guys have working is a nice render.

@@DodInTheSky Yeah I was pretty excited about Starship some time ago but Elon has turned out to be a shitty person, with Spacd X being no diff. All these "newer" ambitious companies like Astra, RocketLab and probably Stoke too have a brighter future ahead

@@DodInTheSky Starship was once a nice render

The more competition, the more progress we could see

Pun intended?

@@curiositytube5924 ;)

Their current design uses the LH2 propellant to cool the heat shield. This heat will also be used to power the turbopump for the engine. The whole reason they went with the metal heat shield concept is for rapid turnaround, with ideally no parts being replaced before the next launch.

@@Ender240sxS13 Hello, I checked the website and as you point out they will use LH in the second stage. Hopefully the alloy is durable! Regards!

@@asynchronous_man the lead engineer/CEO of the company was a PhD student of the professor who taught my rocket propulsion course, and he came and gave the final lecture of that course this past semester, had a lot of interesting information.

Bruhh what, forgotten about spacex already?

These sort of designs have been proposed before with stuff like Bono's Rombus, Chrysler SERV and you could probably chuck X-33 in as well. The big differences between this and the older designs is that it's a 2 stage setup instead of SSTO. Falcon 9 has killed SSTO's as the default reuse method and I'm kinda thankful for it.
