nice metroliner in the back

nice work! I have smaller pulsejet and a little different type (chinese) . but my friend has very similar to yours.

However, valved pulsejet has better efficiency by higher compression ratio.
It is the reflecting pulse (part of outgoing shockwave is reflected back to combustion chamber) that makes the compression - in valveless pulse jet some of this pressure is wasted out through intake tube causing lower compression for air/fuel mixture before ignition. Thus, causing lower fuel economics.

bet it hardly breaks 25lbs

@htannberg well they were valved and the reason the did not go far or fly long is they had 150 gall. of fuel and they got 1 gall per mile so there max range was 150 miles going at 400mph they had a adv. flight time of 22 min. not that the valves stopped working they ran out of fuel and fell

@merlin905 wrong not v2 it was the v1 buzz bomb it sounded like it buzzed as it went over because if was a valveless pulse jet but a bit higher quality than the one in this vid no offense its a great homemade one but the Germans had rocket scientists and lots of funding more then 50 bucks in tubing and propane no offense intended the v2 was a liquid fueled rocket using a 75% ethanol/water mixture for fuel and liquid oxygen (LOX) for oxidizer

No fuel pump. The propane is already pressurized. It wants a lot, more than a barbeque bottle can deliver.

Perfectly tuned!

It should work much better once I make a better injector.

Hi htannberg. Are you going to propell anything with this nice pulse engine??

I would like to one day put it on a go-kart.
