Rocket sled track. Pretty much anything helps.

How would I go about it? what size would I make it? What sort of projects should I put on it (eventually)? &c.  Thanks.

.  If you have to ask such a general question, then you are not prepared to design and/or build one. Do some research and then ask more specific questions.
.  If you plan to build the track near a populated area, I suggest retaining the services of an attorney.

I was looking for general input on a project. It was precisely because I was not ready to design or build one that I asked a broad question. I have no idea if it would even be feasible, and I was looking for diverse, creative ideas. I only really know that I have a lot of semi-flat space I can use, and would like to use model rocket engines for some kind of testing. So here's some more specific questions: what would be a good minimum length for a track? what type of system would be good for rails? what about curves in the track (along any of the 3 axes)? would ti be stable? what kind of foundation would I use? What other factors should I consider? How should I stop the experiment? What would make for an interesting experiment?
> if it would even be feasible
.  For most DIYers on a limited budget, no. But nothing is impossible.

> model rocket engines for some kind of testing
.  Too vague. What kind of thrust are you talking about?

> what would be a good minimum length for a track?
.  Depends on thrust, how long you accelerate, how fast you decelerate, mass of sled, &c, &c, &c.

> what type of system would be good for rails?
.  See previous Q/A

> what about curves in the track (along any of the 3 axes)?
.  Don't do it.

> would ti be stable?
.  Assuming ti = it, what is it? How stable is stable enough?

> what kind of foundation would I use?
.  Too many variables, but lots of re-inforced concrete will probably be involved.

> What other factors should I consider?
.  The fact that you will likely be a danger to yourself and others.

> How should I stop the experiment?
.  Immediately.  Resume when you learn a lot more about engineering, physics, &c.

> What would make for an interesting experiment?
.  Define "interesting"

Thanks. I'll wait on this one. I was just wondering, because I had heard that my school had one 30-35 years ago, but nobody seems to know much more than that about it and I was hoping to reconstruct it with faculty assistance. This seems like much more of an undertaking than I'm prepared for.
