I don't think you want to melt your spark plugs or work with lethal voltages even though it's a hot spark, you want something under the threshold of death running your pulsejet, just in case you get distracted for some odd reason. There are many ways to die, let's not make it too easy. I burned my f...

Cool pics of the PJs. Mark i have a peice of 2inch diameter galvinized pipe with a cap and a reducer attatched to it . the reducer reduces down to a 1.25 inch pipe. The 2 inch pipe is about 6.5 inchs long, So is the 1.25 dia tail pipe. I know i need a longer tail pipe but not sure how long. I have ...

I was just toying with the tiny Logan and it's funny the way it can run sometimes. I put a bell and a brass fitting on the tip instead of that cap and hooked a smaller diameter, foot or so length of silicone tubing to the tip, which filled with methanol, gets pushed around to the side port where it ...

If you are running a pulsejet outdoors, I don't think you would ever have to worry about zinc or galvanized pipe in the least. Mark Often, most hardware stores offer stainless steel, galvanized pipe, and something called black iron which is the cheapest of the three. It rusts easily though but who ...

Yea, I would orientate the combustion pointing up and use methanol. Varying the combustion chamber is a good way to get around a lot of guess work, just as trombone lengths of pipe on a pulsejet exhaust tube do the same. It's a lot of trial and error when fishing for the right dimentions. Some days ...

Re: Free-floating valve?
Would a free floating valve like this work on a pulsejet? If you left off the valve altogether, that shape might run just as a jam jar of sorts breathing in and out through the narrow pipe only. I have a few almost exactly like that shape/proportion that do. But it is some sort of inbetweener. Not ...

Re: Gismos
If you type valveless propane in ebay there are some long side-ported pulsejets, odd but interesting.

Re: It runs
You know, you are going to make the SRL boys jealous. It looks like something out of their gene pool, something atypical with a touch of satire. I doubt they'll be jealous. Maybe once I've got the big engine built, I can drag it out and have a pulsejet battle with their V1. Chris To me this valvele...

More triangle structures ... Have you ever seen those split bamboo fly rods? They use strips of bamboo, each long piece a solid triangle/wedge that is formed/cut to .001ths acuracy or even greater and then they all fit together to make the pole, like pieces of a pie. Some are even carbonized by heat...

To top it off, you might work on a triangle shaped spark plug. T'would be humorous. And emboss a trilobite on the side somewhere. Just some ideas from the peanut gallery or the chocolate factory.

You might call it a trilobite. After all it is made up of three lobes or sections like the prehistoric creatures, the tri-lobites. Looking at it as art, it strikes me as fragmented, repeating forms as likened to cubism. Ought to be attention getting when finished. Wonder if it will make triangle fla...
