Little Little Joe II Test

[Long_Gone]

Doing some calculations and tests for a Little Joe II of approximately 1/96 scale.

Looking nice from here.

 

[Long_Gone]

All this for such a small rocket.

 

[Long_Gone]

OR File for proof of concept. Wanted to see if it would fly.

 

[Antares JS]

That's neat. I love it.

[Long_Gone]

I could not figure out the tower in OR so I offset the mass of the capsule/tower.

 

[Long_Gone]

This is just a small fun day project while it snows here, AGAIN!!!!!

 

[Long_Gone]

Hmnnnn

 

[Long_Gone]

Looks ok the 3D printed tower sucks to paint.

We will see how well it flies and maybe i will design my own capsule and build a tower. Maybe!!!!

 

[Long_Gone]

Pro tip! Print space capsules in white to avoid painting.

[Long_Gone]

These fins suck, I'm getting some thinner balsa tomorrow, will not be scale.

 

[Long_Gone]

Going with this printed in a higher resolution and all painted and vynl applied. This is the flight capsule.

 

[Long_Gone]

Cereal box rings and cut off piece of used engine for the block. Simple.

 

[Long_Gone]

1/16" seems better and it will perform better.

 

[Long_Gone]

Fins going on

 

[Long_Gone]

Parts

 

[Long_Gone]

Looks good from here. The fins are epoxied, I was worried about the glue joint.

 

[Long_Gone]

Almost there, there will be no corrugations. Too hard to do at this size, right now.

 

[Sooner Boomer]

For some reason, this tiny little thing has a big appeal to me. I guess you also do a cardstock model at this scale.

 

[Long_Gone]

Um nope, not yet at least.

I could not figure out the tower in OR so I offset the mass of the capsule/tower.

I guess it's water under the bridge; you could do that as several pieces:

I don't know if it's an issue in OR, but in RS the default reference for expressing the static margin in calibers is the nose cone base, and you'd have to change that to "Maximum forward diameter".

After you weigh and balance the printed, painted part, you can adjust wall thicknesses, override masses piece by piece, and/or add mass objects to the model so that the five parts collectively have the right mass and CG.

The truss would still not be well represented. There OR masters around here like @K'Tesh who could probably do it, but I don't think it's really worth the time. I guess one could draw a surface wrap that would trick the eye and look like the square truss in the renders, but I still don't think it's worth the time.

 

[Long_Gone]

Yea I just did some offsets for mass and did a cardstock cp cutout and am going to string fly it. Should be enough to get what is going to happen. I was going to do it but started to look like this multitransitional monster, so I gave up.

 

[Long_Gone]

Little Joe is sporting some metal accents.. decal clear coat drying and will be applied tomorrow and the booster will be clear coated.

 

[Long_Gone]

Waiting on the decals to dry and then careful clear coat. Install parachute and shock cord, then fly.
LG~

Two Things;

1. Fabulous job - hats off to you
2. I suck at building rockets

I clear coated it and the clear reacted with the chrome and the decals protected the paint under them and it looks like #hit.

LG~

I will use this one for flight and i may build a shelf queen.
