Yes but as for sustainability tell me how long do these things run for at 60 and 70,000RPM and how often do you have to repair them??

I joined [EMAIL PROTECTED] a few weeks ago after learning that you can get everything you need from a junk yard. People are buying auto turbochargers and back feeding the compressor gasses to the exhaust turbine and adding some fuel and an igniter (spark plug).I'm just having trouble collecting data on efficiency for this technique.Mike

I should have said that is not my page. I haven't built a conventional type pulsejet. I just pulled the link from my bookmarks FYI.
I am more interested in the coanda effect and the ferroelectric effect. The problem wih turbines is they are not very sustainable. You have to have deep pockets to play with those things. I want something with no moving parts. (other than phonons :-) )
Just wanted to let you know there are surplus turbines available out there.
Good luck

Hi Joe. When you said Pulse-jet you reminded me of something I saw when I was a kid. It was a small jet turbine that bolted onto your cars differential. It bolted in place of the rear differential cover and connected to your fuel and electrical system. As the car ran down the highway, the turbine came up to speed and you could flip a switch and inject fuel into it for a boost. Primitive but effective. I bet one of these would run well on biodiesel.
Your pulse-jets are fabulous. At first I thought they were scram-jets but then saw the turbine. Cool. How much to they cost?

This is not at all far fetched. Several people are bulding teir own turbines and other things like pulsejet engines etc. However you can get surplus APU's (auxiliary power units) at bargain prices if you look around. Check here: http://freespace.virgin.net/dyno.power/gasturbine/
Fun stuff! Pulse jets are not just for the military anymore! There is even a guy talking about building his own personal cruise missile. =-O Talk about civil disobedience!

Apparently, it's not as far fetched as one might think. I'm still unsure of thermal efficiency and if it's competitive with other cycles. In theory, it should be.
Has anyone done similar research?
