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.

Great work...the best engineered and simple design I have seen on KZread. I cannot wait to see HydroGen 3.

That changing C/G & keeping the nose in front of the fins. Great job.

Congratulations! Nice work ; Felicidades! Bonito trabajo..

Very cool!

I saw it live on Sunday at the RJD 22 event, very impressive Rocket!

Thats impressive, I'd also like to know more about the recovery system and that launch tower! Very cool!

You broke "ARCA SPACE"'s record.

That was Epic!!

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's very cool 🤩🤩🤩 hope you make it into space ❤️❤️❤️❤️❤️👌👌👌👌👍👍👍

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.

Beautiful work. See a challenge, meet it kind of engineer. Just because.

Way much better than ARCA. Awesome!

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?

Super cool !!! Amaging work !!!

Inpressive!

Bro make more videos coz I like rockets ❤️👍🏻🙏

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

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

next try a 2 stage steam rocket

Wow!!!!!

Nice🤩

👍👍👍

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! :)

How are you heating that - the battery pack must be huge or is it chemical heating

Beeindruckend! Das wäre doch was für die Zuschauer in Manching.

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.

How much to purchase this setup

Water is incompressible so why did you design your nozzle with a divergent ?

Liquid water is incompressible, but the steam is compressable

ARCASpace company built a larger size steam rocket from what i know. Check their channel on KZread.

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...

All you need is thrust measurement tool during testing design before real test launch

02:30

if you launch from a cannon barrel, then fire the first stage from up high, how about that

Net schlecht!
