The Pulse Jet Bicycle that Goes up to 75 mph Answered

Pulse jets are fun to watch and you can get an intro to making one with a jam jar. Make a big one and it can be incredibly freakin' loud. Mount it onto a bicycle like Robert Maddox did and you'll get speeds up to 75 mph as you blast your ears into loose bits of jelly.

How many Jam Jars do you think it will take to move my bike at 75 mph?

Hmmm on a second look, I could beat this one, need some work but the chinese based engines aren't that powerful usually, I'm going for either capped end or lockwood-hillers...

That's because it is a WWII buzz bomb. Well, in essence it is. The original use of valved pulsejet engines WAS the V1 and V2. They were designed for it. The valveless ones came from scientists studying German tech after the war.

A similar device has appeared at a couple of the older Western Winter Blasts that I've attended. The noise was impressive, but not so much as the fact that the tail pipe of the thing would glow orange with the heat it produced. How much thrust was produced was a separate matter; while they ran the bike around what was normally used as a racetrack (dirt, for car racing), I don't recall that the resulting speed was particularly impressive...

Well, the link says "could push the bike up to 75 MPH",sounds like advertising speak, when you add a rider, the speed will be lower. ;-)

when I first saw that on another blog I thought it was kinda a joke. from the looks of the picture it looks like it's really off balanced.

this thing is pretty sick. I made a smaller one that makes about 8 pounds of thrust but i didn't mount it on anything.

There's no need to go all the way to Make a Jam Jar Jet.

This is pretty cool. Well, hot, actually. Those things glow.
