Who wants to help me fund this thing? :lol::lol::lol:

Started as a two stager (hence the file name) but you see where it went. Ahhh the lessons in impracticality.

Before anyone takes this too seriously and tries to point out the myriad missing components and failed theory with this model, this was just for fun.

Let's do it!!!

This could be an interesting community project if everyone built a stage and then met at whatever launch site decided upon to do the final assembly.

We would need to enlist some well seasoned staging pros to get the timing right. That would be very cool though and I would volunteer for any portion

My buddy Fred T flew a HP 5 stage...
I'm pretty sure that's the one that went up perfectly....
Check the vids at this past MWP...

Can't run the model at work. What motors are those? and are those 3x clusters in the back?

This doesn't have to be a fantasy...
If you work at it long enough,,
you'll get there...
It'll work,, it'll just take quite a bit of time and effort to get there,,
but it'll work,, you can do it...

I'm not sure what is in booster 1 and booster 2. The OR file that the OP posted only shows three stages, all with N4800's, which sims to nearly 174k'.

N4800s all the away around and yes, 3 motor clusters.

Weird. I'll look at it and repost.

By the time you get to the 4th and 5th stages you probably don't need much in the way of fins anymore. It would be interesting to see the velocity-only graph... what is this at, about Mach 6 or 7 at Stage 5 burnout? You'll need ceramic or titanium for the nose cone...

Almost certain just by looking at it that you could fly it without needing anything more than a lvl3.(Somewhere in the Q+ range) I know, I just had to...

My native file is correct but when I download from here, no good. Let's try it again.

***Edit*** Looks good when I download from here now. Can someone confirm?

That file works fine. Sims to nearly mach 5, 517k', and $10k in rocket motors. Ridiculous. #### terryg ##### Well-Known Member I wonder how far down range it would go after going into cruise missile mode. #### fyrfytr310 ##### Well-Known Member That file works fine.

Think of the view! Lol. I suspect truly modeling with all required hardware, recovery and otherwise, would take some of the point off of that pencil, if you will.

Using my TI-92Plus, I calculated it would travel pretty freaking far. + or - a few miles of course.

I'm sure a lot of you have seen 4-5-6 stage BP rockets fly. There's usually someone at an open major meet that puts some up. Neat thing is how they pull them off. I've seen a half dozen or so fly and they worked fine. Kurt

I think we should try it...

Get volunteers, split into groups, each group handle a stage, meet every now and then or telecon; ask for donations and go for the moon!

I believe there was a 4 stage I saw fly at LDRS 34? Teddy can confirm or deny

Yes Nick,, that was Fred T..
But I think there was an anomaly in the flight at LDRS..
He put up a 4 or 5 stage flight at MWP and it went off with out a hitch...
He's a good man for sure..

Hey, I'm in if we want to get this thing going. Design needs a ton of refinement before we purchase the fist piece of material and we will need solid commitment out of a number of people. Especially a staging pro. I don't personally know Fred (and wouldn't mind reaching out to him) so if one of you do, maybe you could engage him?

I would think a scale test model would be in order too.

Could make a sweet Balls 2018 project.

If some other people around NE Okla ( ks, ar, mo ) are in, I'll commit my bit.

Very fun to think about indeed. Anyone ever try to figure out the minimum build required to hit the VK line at 100km up? This build obliterates it by 50%.

If this does become a reality, I think structural needs will quickly sap away from that altitude. :fly:If it were to fly at BALLS, is metal airframe allowed?

You are absolutely correct there! lol

From what I understand, BALLS would allow for an AL airframe but I always stand ready to be corrected.

#### pondman

##### Serenity now......
Yes, aluminum air-frames are allowed at BALLS. You will also need to think about GSE for this beast.

We'd almost need a team dedicated to just GSE....

***Edit: Does this mean you want in?

Are there hydraulic jacks with 6' strokes?

Raised tower, place sustainer, jack up 6', lock, place booster, unlock and lower sustainer, return jacks to bottom, repeat x3?

Just to provide a GSE scheme about as fleshed out as the rocket, lol.
