Dont think its too easy to decrypt the passwords, unless you believe some of the guys on youtube. I didnt see anything credible online.

Re: Beck Technologies
Well its not that I forgot the original password, it would be impossible to forget, which means it was changed somehow, and could be any length. I tried 3 different keyboards incase something was messed up with one. But it quickly became apparent that it wasnt the original password anymore. I have a...

Re: Beck Technologies
Hi, I'm trying to recover from losing just about all of our current digital data. Our backup computer got zapped, completely fried, and our primary computer's windows login password somehow spontaneously changed itself, probably from some kind of remote intrusion, we were able to forcibly reset the ...

Re: NUDiS trouble
I've tried nudis a few times, every time I get computer upgrades I try it again, but it drives me nuts because I can calculate the performance by hand faster. I dont know if my microsoft office is just ridiculously slow, but it takes thousands of itterations per cycle and you dont get any accurate r...

Re: Building a 3 LB thermojet from plans
Build everything as close to the dimensions as possible, and you will get an engine that will put out over 3lbs thrust. The intakes can vary in size. The flare you put on the intake helps them draw in air easier. A .47" intake with a really good flare will breath better than a .60" intake with littl...

Here's some unfinished stainless spine armor I had laying around.

Re: flatten or unfolding 3d models
Teardrop HDPE mallets, great for metal forming: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=98132 Just need a sand bag, and lay your metal sheet on the sand bag, and pound away with the mallet, blunt side to flatten or lightly curve, pointy side for sharp curves or dents. Maybe ...

Re: flatten or unfolding 3d models
Yep, probably will be easier for me to go get it from my friends and take more pics than to find the pics on my drives.. Power surge wiped out one computer, then windows decided to change the login password on the other, had to hack into it, but now it seems that a good portion of the files were enc...

Re: flatten or unfolding 3d models
You are making a hell of a lot of work for yourself. I'll have to find some pics of the armor I made, all you really need is a sheet metal shaping mallet high denisty plastic, some rubber hammers, and a leather sand bag, could even make one out of an old welding glove. Some round dies, like a smooth...

Re: Please put your "I am new and need help" question here.
From the looks of his feedback rating, I think Aerosplice is using multiple accounts to boost their feedback. Our thermojet's are pretty efficient, the only thing is that they can tolerate the richest fuel burn conditions possible, it will increase thrust some, but the fuel consumption goes up drama...

Re: Pulsejet thrust output
When a valveless pulsejet design is advertised for sale on ebay and it states that the engine will put out a given amount of thrust; is that thrust achieved, using propane vapor? Or will it only put out that amount of thrust, with a liquid fuel? I ask, because I vaguely remember reading somewhere, ...

Re: Best Runner, yet
The internals are proprietary, a basic ramjet will work somewhat with an average pulsejet but for really good performance you need to do more. The big flame in the augmenter is actually a sign that there is quite a bit of fuel blowback from the intake, the augmenter slows the average velocity down a...

Re: ¡Aviso!
Kiran,
You should find many plans in the 'looking for plans thread', might want to look for the classic 55 lb lockwood design, the performance characteristics should be similar to what you are looking for, and is easy to start with the right injector.

Re: Best Runner, yet
Smooth flow might help the engine bring in air for that first pulse, but once it is actually running, and is a good running design, turbulent mixing will result in much more power, and higher fuel efficiency. The farther the injector is in the intake the less blowback there is. But at the same time ...
