Phoeni-XXX my 3 stage Phoenix missile

[sed6]

I already have a 1.6" AIM-54 Phoenix Missile by The Launch Pad, a mid-power 2.6" scratch built with DD and a 4" by Madcow I did my L1/L2 certs on. I was looking to try something different and fill the gaps in size.



I settled on the 2.2" BT-70 for my next iteration and decided to make it multi-stage just for fun. The idea actually struck when I considered making the bottom fins, or their fin can, removable in case they needed repair. I designed a removable lower fin can in Open Rocket first. Then I thought I'd make an extra, just in case. Then I started stacking them and decided to make it a multi-stager!



Here's a concept pic and a teaser pic. I am about to apply paint and thought I'd start a thread to show my work if there is any interest.

Gee, I dunno..

That's a pretty ordinary looking rocket.

With the additional weight of all the motors in the stages, how much weight will you have to add to the nose? Will the total weight get lifted with the initial booster motor? What's that motor?

Hmm. There is nothing ordinary about a Phoenix. Great missile from times gone.

lots of fins.

She's under 6oz. No weight needed for a one or two-stage rocket. A D12 gets it up to 500 ft. If I add an ounce to the nose, three D12's get it up to 1,300 ft. This picture tells all...

I forgot all about fillets until the time came. Took me a minute to remember my paintbrush dipped in a small cup technique. A popsicle stick or a wet finger does a great job at keeping them even and consistent.

That is a good technique

 

[Pinetree]

No, not ordinary at all.


(I was being facetious, but it doesn't seem to translate well.)

I got it, and started laughing. It was very funny.

Yeah, nobody wants to see another rocket. Especially not a multi-stage Phoenix, somebody just whipped up cause they thought it was cool. I mean get out of here with that. Ahahahhahahahahah

Very cool work! I like it.

Agreed…nice looking rocket. Unfortunately the Estes 2.6” version was prone to “cruise missile” sideways flying due to shifting cg by internal weight of an added optional heavier (nylon) parachute, too much wadding, not building bottom fins properly ( wrong grain/root direction), and not enough nose weight (Estes clay) added. Fun to watch for sure…

Thanks for the positive comments! Here's my AV bay. I 3D printed a threaded coupler and have room to mount my egg finder with its battery plus an altimeter. There's also 1 oz of removable weight at the tip. I don't need both, either 1 oz of weight or the tracker but not both.

Nice tracker bay design. Is the weight magnetic?

Thx! Yep!

STL for the coupler?

"Just a jar" Having the imagination to see ordinary things in other applications is a rare gift, don't downplay it.

Cool screw-on system. Is that the Rocketarium BT-70 cone?

 

[sed6]

Thanks! Yes it is.

To true, a have never been able to do that sort of thing.
