Well I had a 9 hr drive home yesterday and I spent nearly all of it prototyping my missile system in my head and I think Ive come up with a system that perks my interest sufficiently.
Now in the article I read a mechanical pull pin was used to unstop the missile for launch. This also required an external protrusion on the bottom so there would be room to pull the pin completely out.
Now the mechanical pull pin system works but, I want this think to kind of operate like the real thing. So, I have to step it up a notch. The real missiles are launched using steam like a pop gun.
My first idea was to create a series of 3 ring seals in the tube and make a small burn chamber to the side with a "A" size estes rocket motor in is that would fire onto a small chamber filled with water. Now this seemed like the option with the highest cool factor but, not very practical and expensive. I also could not remember if those things had self oxidizers like magnesium or aluminum oxide. If they didnt I would never get a full burn or if I got to big an angle the mote would get wet and be worthless. Another issue I saw was that once the missile cleared the surface It might fly a foot in the air and then abruptly stop without its own power system.
So I am now on version 4 or so and here is what i have.
I wanted to keep the idea of a gas assisted launch system but my only concern now is will the propel have the proper pressure to "pop" my missile of its seal pin?
Pete if this works your getting a freebie in the mail.
