propane supply safety.

Hi all,

I am currently working on finnishing up the build of my first jet engine, made uaing a turbo.

All the major components are done, I.e. combustor, oil supply, fuel nozzle.

The only thing left to do is connecting the fuel nozzle to the gas bottle. Not that big of a problem but I'm wondering if there is any need for a flame arrestor in the supply line?

I kinda like the idea, even if it's just to put the minds of worried parents and friends at ease.

But this would mean I have to find adaptors to fit flared (welding equipment) type couplings to a tapered gas thread. Which I haven't been able to find.
(So it's easier just to leave it out)

What's your opinion on this?

Propane need oxygen at the right percentage to burn at all, so i think it is unnecessary. I dont know how it is with the flow with a flame arrestor, we need all the flow/pressure we can get from the bottle to drive our engines.

Hi Davy

No need for an arrestor , the fuel pressure has to be higher than the combustor air pressure otherwise the fuel can't get in, the flame goes out and the engine stops .

Thanks you both for your replies, that will make sourcing parts much easier.

Can't wait for the first test start
