Re: underwater operation of pulse jets
(hey all, just dropping in to see what's happening) This one tweaked my interest. Yes... the whole thing past the intake can be submerged although the exhaust opening can not be to far under the surface due to back pressure. The intake can handle a fair amount of steam/splashed water although it can...

Re: Kindle
I am writing this on a phone right now. The one that i also have some books on. I had only noticed with mild interest these reading pads bafore although am taking more notice now. Reading on this phone is great but only 'better' than a book for small reasons. 1. It is small! If it was kindle size, i...

Re: I got this....Any ideas for it?
Its not a question "can I", it should be a statement that "you must". Very nice score! Keep searching around here and the yahoo group gas turbines. Once you get a feel for where you are headed and what you want from it put some ideas up and one of the experts will be sure to chime in and give you as...

Re: Varying the thust in a pulsejet
A couple of notes to also consider when presenting a depiction or description of pulsejets. They do not spool like turbines. Everyone here knows who im thinking of. "dragster" whiiir whrrrrrriiiiiiiii, "im a jet" With increase in throttle and power a pulsejet just gets louder at basically the same f...

Re: Basic Gasifier Build
Hey Pyro, Ive been playing with a prototype now too. Only had enough time to build and fire it up once. Many issues to work on yet, although it certainly gets into a strong resonant mode. The vid has no sound.... and nearly completely useless for showing anything, but i had to throw something in wit...

Re: Turbines driven by pulse jets
V's, Big end splash fuelled 2 stroke maybe, drip vaporiser like. "...squirting fuel into the cylinders", atomization? seems a little higher up the ladder for us monkeys. (I for one liked the general whole community encompassing compliment/insult combination) ;) Fuel atomisation(or other), metering, ...

Re: Basic Gasifier Build
Hey Pyro, Good to see you putting it to steel, mine seems a long way off yet. I'm collecting some good info although it is slow going to collect, compare and refine it in usefull order. Ill put some of the more interesting things up here for some background and ideas. Yours reminded me of this one. ...

Re: Simple Conduit Engine
Yep, cig lighter for ignition. There is a certain knack to it, easy when you know what your listening for. My SLI vid on youtube shows me doing it (i think that one is a good example of cig lighter starting) Another thing that engine in the vid had was a slide on tail couple, which is where the smok...

Re: Simple Conduit Engine
hahaha, classic, "3 hours spare... what can i do? PULSEJET!" I'm sorry to say my friend, you have the bug and its incurable. It will mellow with time, although there is nothing that can be done for short term relief. Just be warned, compulsive sporadic pipe creation assembling activity can be a conc...

Re: Solving Thermosteel fragility problem
Hey guys, Someone was working with ceramic jets at one stage, Craig i think. Its possible, and we would all here be very interested to see how you go with it, from memory it ended with a busted engine or two last time before being abandoned.

Re: Towards a wood fueled pulsejet
Mate, this is very cool! I was getting a nervous tick wanting you to crank it up, although i do understand some small need for more than one run. ;) [subliminal](bigger engine, bigger engine, bigger engine!) [/subliminal] Impressed by the revs considering your mentioned ineficiencies. On top of want...
