Hot Water Rocket / Steam Rocket - World Record Attempt

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?

Congratulations! Nice work ;
Felicidades! Bonito trabajo..

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

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

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. 🚀🙂👍

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?

50Bar that is a lot. why only 400N thrust? can be temperature right? Onraptor is 300Bar at 1600ºC and give 2000kN(2tonne of thrust).

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