So.... you still looking for more concentrated peroxide ?? 👀

[sidoslaven]

A good idea might be to keep using the two syringes and have a small yet powerful electric motor( low KV, 150-350 KV probably ) and a setscrew to simultaneously push on both plungers. If the speed of the motor is to high, i recommend printing a gearbox to increase torque while slowing down the rate of fuel consumption.

I understand that this complicates things a great deal, but hey...it's Nazi rocket science, what did you expect?

Anyhoe, well done! Keep up the good work.

Two points about rediscovering old chemistry. I am a lot older than you and our chemistry teacher in 1966 was working during WWII in developing 100 vol hydrogen peroxide for use in rockets etc. He was called Dr Roper. As far as I know the V1 a heavy brute of a rocket needed to be shoved up into the sky at reasonable speed before it would fly off it’s pulse jet. This was achieved as aircraft on an aircraft carrier. That is a tube with a slot along the top on which the rocket sat on top of cylindrical slug. The slug was propelled up the launch tube by the mixture you are describing. The slug fell away in front of the launcher. There is one by the road visible through the hedge at Duxford Museum near Cambridge UK. The steam generator is also there with quite a number of chambers and pipes to hold and control the chemistry. The are bound to be pictures somewhere of it perhaps on Wikipedia.

Dude the quality of the editing of this is amazing. And the unobstructed confidence when delivering lines, even during the zoom ins, is legendary.

Catalytic reactions are typically directly proportional to the surface area of the catalyst. Swap those beads of silver for silver mesh and place in the nozzle. H2O2 which doesn't react with the KMnO4 (common, due to the violent nature of the reaction and limitations on reaction vessel volume) will get another reaction chance with the silver (it also promotes mixing). Also, a bit of tweaking to the design of your reaction chamber and mixer will help limit the backflow issue you're having. For the mixer, redesign to make it conical around the nozzle (the cone going IN to the chamber) and for the reaction chamber you can add angled (baffled) steps to the side so that expanding gasses favor moving towards the walls of the chamber and nozzle (this also reinforces the chamber which allows you to make it thinner/lighter). Beyond that, you just need to get the H2O2/KMnO2 ratio correct and figure pump(s). Bonus points if you put Tesla valves between the pump(s) and mixer to further limit pressure backflow. - Video idea: Steam Rocket Engine 2.0

Do not use syringes, use pressurized tanks instead! Take two pressure tanks for propellants, and third tank just for compressed air (a few bar in Coke bottle should be ok). Connect both tanks to third one using some valves. When valves open, high pressure air will push the H2O2 and catalyst out of them into the chamber. This is safer since you can close the valve in case of emergency. This also would provide better control of the mixing ratio. Also a good idea would be to use check-valves to prevent incidents of pressure backflow from chamber.

Careful when mixing those combinations. Surely you have heard of the German pilot who was fatally burned with that stuff due to a leak while his craft was being fueled. Really like your content and style of delivery.

[juliandoye]

Great video, just a note: at the beginning you are mixing up in the videos two different aircrafts: the HE-176 and the ME-163. Just saw the latter one in "Deutsches Museum" in Munich/Germany. The ME-163 came after the HE-167 and was actually in use even though with little effect.

[PlasmaChannel]

It would be interesting to use a FLIR and see how much heat the steam produces, in real time, plus see the primary catalyst points. Good job brother!

[owenkegg]

I love how he didn't even want to talk about a hypergolic rocket engines.
Scary stuff.

[Lampe]

1:27 I have a fuel, I have oxidizer,
Ugh, fast combustion!
I have a pipe, I have some lids,
Ugh, rocket shell!
Fast combustion, rocket shell,
Hugh hugh ahh, hugh ha-ugh, combustion thing that flies away!

[ralphanderson]

Integza great video. When I was a kid I made a compressed air and water rocket for a science project. I bet you could make a powerful compressed-air water rocket. Thanks and keep em coming great work. Peace.

[MakersMuse]

I remember seeing the test footage of one going full vertical and absolutely losing my mind - the interview with Hanna Reitsch is really interesting. They use hydrogen peroxide for some rocket drag cars - make a mini one! :O

Test until failure is a common strategy, we don't typically include humans in the failure mode though.

I can't subscribe to your patron but your content is good enough to where I'd be willing to go through to ads and whole video so you get money

[Generic_Tech_Support]

OMG i have found the best channel on YouTube! This is amazing! This guys incredible! Keep it up bud! Amazing work!

[benjaminmiddaugh]

There's something so gratifying about watching someone who clearly isn't mentally prepared for the reaction they are initiating.

[bluewater]

I did a thing is a really funny channel to and also a very well put together show like this.
I get a lot of enjoyment out of that channel and this one like others that are similar.
Again I'm surprised I'm just learning about your channel just recently.
Thank you for the time you all pt into this for us.
I personally very much appreciate the time I get to smile and watch videos.

[dbmail]

I'm really amazed that such an energetic reaction produces so little heat.
