Hot Water Rocket / Steam Rocket - World Record Attempt
HTML-код
- Опубликовано: 12 сен 2024
- Some technical details of the rocket and its engine:
- 1000 g water
- titanium pressure tank (wall thickness 0,7 mm)
- tie beam construction
- nozzle diamater 4,0 mm
- structure: epoxy-class resin
- to be continued...
Caution! This is not a guide to rebuilding. The construction requires special technical and physical understanding! Handling hot water and pressure vessels can cause serious injuries! Don't do it at home!
That's very cool! Looks like a very well engineered project. What was the dry weight of the rocket?
Hey guys from AIR COMMAND ROCKETS. I am honored to have the first comment from you! You also have very exciting projects. It's a shame it's a bit far away to watch. The dry weight of the rocket is about 1,5 - 2,0 kg. That depends on the parachute and payload configuration. However, the absolute minimum is about 1,5 kg.
400 N*s from 1 kg of water...so your specific impulse is approximately 41s, right? Or did i do my math wrong?
Also, are you blasting out superheated liquid, or do you have some sort of inverted-siphon tube that only allows gas phase out?
Anyway, awesome build.
I was just thinking of a small version of this you could use over a camp fire. With a nozzle and a tin foil burst plate in the nozzle. Put some water in set it on a stand over a fire until the water boils and builds enough pressure to burst the foil propelling the rocket upwards. Stumbled upon this after a search to see if anyone’s built something like that before
Great work...the best engineered and simple design I have seen on RUclips. I cannot wait to see HydroGen 3.
That's a really well put together system, I like it! Is the max pressure 50 bar? I'm thinking that charging the tank with nitrogen to get the pressure higher would increase performance, so long as the pressure can be safely contained. Unless the goal is to use steam pressure only of course...
That changing C/G & keeping the nose in front of the fins. Great job.
You broke "ARCA SPACE"'s record.
Beautiful work. See a challenge, meet it kind of engineer. Just because.
I saw it live on Sunday at the RJD 22 event, very impressive Rocket!
That's very cool 🤩🤩🤩 hope you make it into space ❤️❤️❤️❤️❤️👌👌👌👌👍👍👍
Thats impressive, I'd also like to know more about the recovery system and that launch tower! Very cool!
Congratulations! Nice work ;
Felicidades! Bonito trabajo..
Brilliant!
A few points:
Cold water rockets have reached higher than 900 metres.
Can you use H2O2 with KMnO4 as a catalyst? Technically, it would still be a hot water rocket, because steam and pressurised Oxygen are generated.
Is there any power/weight advantage to using that method?
The text at the end of the video is illegible on a tablet or phone, and would be much more effective if it was higher contrast, such as white on black, or black on white.
Thank-you for the excellent video.
Best wishes with your future launches. 🚀🙂👍
I've been testing hot water rockets,
main advantages are :
low pressures as the gas volume is maintained by temperature
very easy to manufacture,
the fuel is inert so safe for taking on public transport,
scale-able don't cost much regardless of size,
Disadvantages:
seriously limited by high temperature material properties. (aluminium strength is about half by 400' centigrade) (plastic and composites fail even valve seals start to melt)
small water rocket win due to super light low temperature composites, but they don't scale well.
if your interested ill have some graphed data on there overall performance from my next vehicle on my channel in a few months
I would have been much more dismissive of the video in the feed except for Mytg Busters. Their episode on hot water heaters was crazy. I have built model rockets that didn't go as high as the water heater did. Really cool steam rocket. Scary power stored in that thing.
Way much better than ARCA. Awesome!
Really? Why?
Very cool!
Holy shit dude, this is fucking amazing! Do you have any idea if water as a propellant could be useful for retroburn landings for a really light, small, lander?
Great
Bro make more videos coz I like rockets ❤️👍🏻🙏
How are you heating that - the battery pack must be huge or is it chemical heating
It had a dome jet stream or something upper atmosphere by looking at the trajectory. It is not the earth motion that fast but the Jetstream block all rocket from normal flight even airplane
That was Epic!!
Multistage can achieve thousand miles for space burial services
@HydroGEN is there a way I can contact you? I would like to learn more about the rocket and its engine, and currently there is no contact info on your about page. Thanks! :)
Wow!!!!!
What’s the average isp?
@E Van how is it related?
50Bar that is a lot. why only 400N thrust? can be temperature right? Onraptor is 300Bar at 1600ºC and give 2000kN(2tonne of thrust).
The size difference...
The Raptor engine runs at 1500°C hotter, burns very energy dense fuel in liquid Oxygen and has a very much bigger combustion chamber, nozzle and bell than this rocket. Other than those tiny differences, it's essentially the same idea: Throw as much mass out of the back end of the rocket as fast as possible.
👍👍👍
Super cool !!! Amaging work !!!
Ótimo parabéns
next try a 2 stage steam rocket
What if you had spring loaded fins and fired the rocket out of a 20’ or 30’ gun barrel (Steel pipe) vacuum on the barrel then add 400 psi air cannon under the rocket...put a cable in the barrel to release the rocket motor 4’ from the end of the barrel...should give you a great height... I would try just the barrel first, then the vacuum barrel then add the air pressure underneath...
Beeindruckend! Das wäre doch was für die Zuschauer in Manching.
Samstag, ab ca. 11:00 Uhr ;-)
@@hydrogen4046 Fantastisch!
ARCASpace company built a larger size steam rocket from what i know. Check their channel on RUclips.
Water is incompressible so why did you design your nozzle with a divergent ?
Liquid water is incompressible, but the steam is compressable
Or naya naya vidio banao bhai
Nice🤩
Inpressive!
How much to purchase this setup
All you need is thrust measurement tool during testing design before real test launch
Net schlecht!

if you launch from a cannon barrel, then fire the first stage from up high, how about that
This is American Shaolin Kung fu
its german tho
100 grams why not say 1 kilogram. compensate much?
Because there are 1000 grams in a kilogram.
1000 grams is 1.000 kilogram, not just 1 kilogram. Precision matters.
1 kilogram is 1000 grams not 100.
'Kilo' means 'thousand', not 'hundred'.
@@ViniciusVetor If you're gonna be a pedant, no actually 1000 and 1 have the same number of significant figures. 1000. and 1.000 have the same number of sig figs, but not without the dot at the end of 1000
38k views, 50 comments. You wasted your time. Steam power has a place and it's not rocketry.
why so salty about that?
@@fr_rave It's technical..... not personal. :)
@@ebenwaterman5858 i said that because he wasn't trying to make some revolution in rocket engineering, it was simply a fun project
@@fr_rave AAAARrgh.... Now I feel bad about my knee jerk comment. Sorry. It was a real class piece of engineering and construction. Kudos for that. :)
