That's a pretty weird setup.


One thing, if he had a larger fuel metering jet than standard for gasoline, maybe the needle valve could meter methanol or choke it down to run on gasoline which requires lower fuel per air ratio. When I bought my Bailey Jet, it came with 3 or 4 different brass ...

Unique to see a needle valve on a typical Tiger Jet.

If you haven't seen Elements of Flight Propulsion by Foa, this last chapter on Non-Steady Flow Thrust Generators has some drawings of pulsejets toward the end of Chapter 15, if you pass through the graphs/math in the middle of the chapter to get there - just some tidbits maybe of interest.

I remember coming across Tyndall's book entitled SOUND while roaming the stacks at my university for something to read. Later I bought a copy, but you can have it from the link in the description too.

That looks like a pretty well made motor.


The welding seams are much smoother than my Dyna-Jet or smaller Tiger Jet. The Bailey Jet I bought has very smooth seams too. I recall seeing some Dyna-Jets with rather blobby welding. Seems like he could spring for a smaller or shorter spark plug ...

Seemed like a first-timer.

Seems like I remember something about the linear or near linear Schmidt Tube pulse jet developing the highest peak pressures but can't recall a reference, perhaps Tharratt or F.H. Reynst's literature?

A lot of noise, maybe deaf cows.

This would make me nervous if you got the fuel/air ratio just right and if for some reason the flame front behaved differently.

I got a CM-6 10mm spark plug to buzz by running it upside down on this acrylic sheet, but here's an even smaller upside down 1/4 32 glow plug slowly getting up to speed. It's noisy for a small spinning top.
