PulseJets

[Simon Howes]

Dear peeps,

I've decided the hax is not nearly dangerous or noisy enough and I'd like to offer an overcomplicated solution to this problem *trollface*... A pulsejet!

More specifically, a micro one.

In the vein of crowdsourcing i was wonder:
.has anyone made one? Has one?
.does anyone know of any plans online for a teensy one (free would be ideal)

That is all

I am keen on building one, have seen it in action in R/C shows, know a bit of theory :)

Okay, I've come up with a few ghetto pulsejet designs suited for the attentionally deficit. Will prolly try them tonite

is this because we talked about jet engines yesterday?

i suppose i could compromise on a pulse jet /sad face

tom - what happened to the idea of using an old turbo and a baked beans can to get a jet up and running? did it go nowhere?

btw be warned they are very noisy....100db + close range

Google for 'jam jar pulse jet'.

Wear eye protection...

a friend made pulsejets out of wood. cut the shapes in layers then glued
them together. ran until they burned up.

perhaps google for "wood pulse jets" or i can ask my friend

That's OK I always use eye protection when googling...

I've been dancing around building a pulsejet ever since I saw the
youtube video of one strapped to a pushbike. Count me in for any high DB
shenanigans in the space.

Helooo,

I made a little cute brass one-way valve last night on the lathe.
Alas, the pulley on the lathe then gimped so i had to stop making my combustion chamber :/

Gonna fix it at lunch today and see if i can finish it.
According to one of the pages (badly paraphrased here) you can make pretty much anything run as a pulsejet as long as the exhaust tube is long enough. So I'm going to just heat the engine till its redhot with a blowtorch and introduce fuel.

Looking at some peeps construction projects it doesnt look like making an engine from scratch is really too much of a mission on a lathe. Mainly though you need to stear away from welding as we dont have a tig welder and welding sheet metal is a black art.

I'll tell you how it goes
