I used to live on Vancouver island (military rotation). The geology is really fascinating over there, especially from a place that had none. I used to go over to the trent river and just pull up fossils.

A few shots I've taken, some I dunno if I like how they turned out

Do you interact with things that have been in space?

I have bolts from the Antares rocket that exploded -

What funny/interesting thing happened in your life today?
RoadRunnerAerospace replied to Ultimate Steve's topic in The Lounge
Not trying to bring relationship problems here or anything but.... First break up, ever (sorta kinda, we're friends now). Quite frankly I was expecting a lot worse than what it is. -
A couple examples of some stuff I listen to

Happy New year's!

You can't do what you don't do. Give em a try, maybe you'll like it -
But what about shock absorbers, don't want to crack the thing in half

It's funky and I like it -
Roadrunner's rocket endeavors

So quick update, I've fired off 3 motors as of late, the most successful had a mild rud about 3/4ths of the way though the burn, causing the washer I'm using as a makeshift nozzle to fly off the motor. Note that this was from a tripod, I'm not standing anywhere near this Note: the first image wasn't the same test as the second, but it was a good picture -
I have awoken from my slumber... Thanks mate, let's hope for a couple more thousand, maybe more, who knows

3d Printed Pulsejet Project
RoadRunnerAerospace replied to RoadRunnerAerospace's topic in Science & Spaceflight
I've already checked out the libraries, nada. I've developed a design with copper fittings that would be a good step in the door, abiet extremely crude and not optimized in any way, shape or form -

Note, this project is on hold till the school actually gets some 3d printers -

I like the faceless figure, makes it distinct -

thats funny, im using epoxy for my pulsejet, which isnt quite as extreme, but its just interesting -

I would have never thought that epoxy was exothermic, I'll have to look further into it -

Yeah was is looking like the best idea, baking would also harden the epoxy -

I think I'm rolling with the epoxy mold idea (I did a couple calculations off paper too if you're wondering where I got those numbers -

That is a very good idea, it's sort of like carbon fiber if you really squint -
3d Printed Pulsejet Project
RoadRunnerAerospace replied to RoadRunnerAerospace's topic in Science & Spaceflight
OK so if someone can "sanity" check me that would be great. The thrust caused by a pulse jet is of course, the pressure acting against the walls, etc. So if I were to make it small, and I mean like, 5 inches long, could I possibly reduce the required pressure for combustion/thrust, and therefore heat? I know it works that way with rocket engines (in a perfect world), and pulsejets use a variant of the DeLaval nozzle. As of current i'm looking at a safe run time of 1 minute at 124°c/minute, so at 2 minutes I'll be exceeding maximum operational temperature of the plastic, through the insulating epoxy (Quiksteel), and melt the extrusion material. I'm wondering if during the mixing process I can put some insulator in with the quicksteel to decrease its thermal conductiveness. -
