I am looking for a set of readable, english, free, pulse jet plans. With materials list and opperation instructions. Thanks.

Good LUck on the FREE part but you can check with the itilian manufacturer Zmodels they still make them along with jet kits for them.

Hi,
There are plans around (I have most - somewhere) which were downloaded from Keneth Moller's website (which appears to be down at the moment).
These are not that easy to make or get right though and require a great deal of care in there operation. You might be better sourcing a commercial engine like a Dynajet or Bailey engine as these work great. There are others available as previosly mentioned, from Z-Jet in Italy which are OK. Depend on what it is you want to do and how big an engine you want?

Pulse jets are band, at show flying here in the UK....

Hmmm,
Not sure on that one. I think it's more the case that turbines are used instead due to the easier operation. That and there are not many people who have the experience in dealing with this type of engine. As far as hazard goes I think turbines are actually probably more dangerous. Most pulse jets seen at shows are not actually that fast. The fastest is probably Bennie Van De Goor's which has been clocked at arounf 270 mph or so. The models the Ghost Squadron flew were much, much slower, infact slower than most turbine models these days.

Personally I still think the spectakle of a fast and noisy pulse jet takes some beating. Wonderful noise!

When you go to jet meets they put on the entry form no pulse jets.....So why do they say this

I have onmly ever heard a pulse jet on video tape but I would love to hear in in person!
As for being banned at shows, I suppose you don't have to fly them at a "show" right?

Jet meets and shows are two different things.
The big shows usually have there own insurance for the event to cover any possible accidents and don't rely on BMFA insurance. I imagine the main reason they're not allowed at the normal jet meets is due to the noise issue. No dispute there! Still think they sound great though (that's why I have one).

I will never forget the Volcan at the Nationals years ago with 4 in there.....Noisey they were deafening!
Flames out the back was funny to watch!

in a well desingned pulse jet the flames should all be contained
hmm, i have some down loaded plans, maybe i could build one after my year of machinists training.

Ifly.
True. Only on wet starts which they do not like at all.

Have you downloaded the plans from the AMT website? This is somewhat larer than the average pulsejet but works well. Its worth bearing in mind the hardest part to make is the actual pipe which is usually made from either thin stainless or inconel sheet tig or spot welded. Not easy to do a good job on such thin material.

The hardest part is getting the things going and finding the right mixture for starting. Once found on a good design starting is easy and the scariest/exciting part.
