Re: Proposed: Linear FWE Rebuild

Hi Larry
I guess as I didn't know the dims so I was guessing at the scale. I have a couple of other projects on the go (a Stirling engine for one, advice = don't buy a cheap Chinese lathe) but will start with this ASAP.
Cheers (Thanks)

Re: Proposed: Linear FWE Rebuild

Hi Larry
I like the configuration :)
If you post or send me the dimms for a 1/3 scale + -, I will build it (in steel) and test for you.

Re: Hi all! (Newbie)

If you want to start EZ then build a thermojet, available from Eric Becks website or elsewhere here. I would suggest starting with gaseous fuels first i.e. propane/butane.
It is much easier to assimilate understanding of starting and function.....if you require more info just ask.

Re: valveless pulsejet for beginner

You could try this one simple and EZ to build, if you dont want to use a spark plug a sparkler can be used for ignition.
Cheers
and have fun

Re: Hey all

Thrust is unknown at this time, they have not been fabricated yet...if you would like...feel free to build one and try it.....I am waiting for Larry to run them through nudis (I think that's the name) and advise tweeking or final adjustments to the draft designs.....I just like the looks of the FWE.

Variant #1
single intake to start second optional and probably 1.5" instead of 2".
A bit shorter..just because.
