Making a pulsejet with my grandad!

[jakegazzard]

My grandad told me a few years ago that during the war he used to wach the V1's fall and drop on london. He then said about it was powered by a pulsejet, as im sure many of you know how simple they are, just a long bit of steel tube hollow, combustion chamber bigger tube than the tail pipe. Not a great explanation i know! Have any of you built a jet? I'm working on the plans now.

Jake, those things are an explosion waiting to happen mate, steer clear unless you've got proper access to the tools, materials and expertise to do it properly. If one of those things blows it'll blow shards of red hot metal in every direction.

..now that's just downright pessimistic. The real question should be waht cool helis has he got that we could buy cheap after it blows?:)

There was a scrapheap challenge episode some 4yrs ago where they built pulsejet carts..they really do need welding skills and the right tools and stuff... and a serious approach to safety.
The episode might be findable on dvd somewhere or ask channel4

Having said that some of the old modellers at our field say they played with them in the 50's...not sure if they were kits or total DIY

Cool I guess your grandad knows what he's doing as its all down to the right plans to get working right.
I looked into this years ago to power a streetluge never got round to it.
Just found a bigger hill LOL The gold old days before kids etc had to give up trying to kill myself.
Have look at the vid.

They fly pulse jets at the Nats every year in the control line circles - you can hear them for miles! Make sure you have ear-defenders! (I am NOT joking!)

A few years ago there was a mad Dutchman (or was he Italian?) had three of them on an RC delta. I've got some video of it in action somewhere - awesome, but seriously dangerous!

You cannot have them running on the ground for more than a few seconds, or they start to melt! You have to release them as soon as they start to provide air-cooling!

Not for amateurs!

John Greenfield (of Ghost Squadron fame) flew an RC pulse jet a few years ago. You might want to talk to him about it!

Jake I found [URL="http://www.pulse-jets.com/"]this[/URL] website which seems to have a minefield of info on pulse Jets and also a forum as well :)

Just don't come crawling to me when it explodes

[Rotorhead]

Sao, they should market that as "Fart in a jar" they'd make millions!

Or just go for a jet cooled beer cooler [url=http://www.asciimation.co.nz/beer/]The jet powered beer cooler[/url]

Great site, and the owner (Bruce) was the one who made the pulse-jet car on Scrapheap challenge. Definitely worth spending a bit of time on his site, also he has another site more exclusively to do with his mad inventions. In fact .. I just noticed he has a wikipedia page that seems to link you up quite well. [url=http://en.wikipedia.org/wiki/Bruce_Simpson]Bruce Simpson - Wikipedia, the free encyclopedia[/url]

He has a youtube channel and has some video of his RC pulsejet plane!

[Supercaptaincrash]

i thought you had a boat now jake?or was it a minimoto? please get a video of the first flight with the pulse jet!

[Smoothound]

Don't worry there will be something new tomorrow ;)

[tiddler]

Well at least it shows he's got an active and inquisitive mind ;)

He just needs to be careful not to blow his blerdy head off whilst enquiring :ack2:

I have two RC pulse jets that are or were made in italy by a company called ZANNIN i think.
Some of you may have seen these fly at wings and wheels some 15 years ago when a guy was flying a delta aircraft with THREE of these on top.
Getting one started and running is hard enough let alone 3

As quoted above by PCHRISTY
These are the same ones as this mad dutch/italin guy and ghost squadron used
