Thanks, Craig. I really don't remember, but my original version may have been V5 on disk, then upgraded to V7 by download. At least the pdf manual that is in my files appears to be from V5, RS5MANV2. At any rate, my engine compiler, COMPENG, only looks for the RASP or .eng files.

Try the latest DEMO from Apogee to use these files. It's good for 30 days (I think). I'm really waiting to see what version 9 might have in it, if and when it finally comes out.

Default Tube sizes used in these new plans...

Folks, I had to create some new tube sizes to use the 10mm and 15mm motors, so keep in mind you can't just order up these tubes yet from SEMROC to build anything. These new tubes -- called ST-4 and ST-6 -- will need to be manufactured and sold to Carl first.

Another reminder -- Carl may not select these sizes for the final parts. He may have something else in mind. But for now, these are the dimensions I am using.

ST-4 dimensions: 0.399" ID, 0.425" OD Wall thickness 0.013"
ST-6 dimensions: 0.594" ID, 0.620" OD Wall thickness 0.013" [thin wall]
ST-6 dimensions: 0.594" ID, 0.636" OD Wall thickness 0.021 [thick wall]

Hope this will help everyone with their new designs.

Exclamation New Plan -- Korviena

A little more ambitious project here...

A sibling to the (still untested) Andromeda, but using only a two-cluster 10mm mount.

Length: 29.2"
Diameter: 1.04" (ST-10)
Fin Span: 8.08"
Weight: 1.84 oz

(2) A8-4.......315'......Dv 10 FPS
(2) A10-4......355'......Dv 13 FPS
(2) A3-4.......365'......Dv 9 FPS

All motors reach flight velocity on a standard rod.

Enjoy!

Exclamation New Plan -- Mini Tom

Based on the Centuri Long Tom, this two-stage model fills my requirement for a "Schoolyard Sounder" nicely. Everything happens within visual range, too. All motors reach flight velocity in the length of a standard rod, though admittedly at the very tip of the rod...

Length: 24.0"
Diameter: 1.04" (ST-10)
Fin Span: 5.04"
Weight: 1.16 oz

1/2A6-0 | 1/2A3-4......280'......Dv 17 FPS
A6-0 | 1/2A6-4.........355'......Dv 5 FPS
A8-0 | 1/2A6-4.........375'......Dv 5 FPS
A10-0 | A3-4...........655'......Dv 10 FPS

Enjoy!

Exclamation New Plan -- Skeeter

This model tries to use a wide variety of power cores to get the optimum results. It may be a 3FNC, but the performance is great, and the semi-open-frame fins give it a bit more personality.

Length: 17.463"
Diameter: 0.908" (ST-8)
Fin Span: 5.91"
Weight: 0.84 oz

1/2A6-3......122'......Dv 15 FPS
A6-4.........323'......Dv 2 FPS
A8-4.........363'......Dv 1 FPS
A10-4........422'......Dv 2 FPS
A3-4.........428'......Dv 6 FPS
B14-6........786'......Dv 5 FPS
B6-6.........787'......Dv 15 FPS
B8-6.........806'......Dv 8 FPS
B7-6........1012'......Dv 6 FPS
B2-5........1021'......Dv 10 FPS

All motors reach flight velocity on a standard launch rod.

Enjoy!

Default New Plan -- Lune R-1 Plus 1

Let me start by saying the Semroc Lune R-1 Retro-Repro is a really cool little rocket

I wanted to design a "new" two stager and wanted a sleek light weight sustainer that looked good but would fly well on some of the estimated engine simulation files that Craig created.

I just couldn't get past the good looks of the Lune R-1 so I built a booster for it. The nice thing about this design is you just toss an extra set of fins in the bag with an extra motor mount and a short 3" piece of ST-10 and it's ready to ship. The Lune R-1 sustainer is already set up to carry a payload.

I simmed it with larger Estes D and E motors and the design would lend itself well to a slight upscale to SLS proportions using LT-125 for the airframes (although there are no LT-125 or ST-13 conical nose cones listed at this time).

Minimum velocity for stable flight reached at just under 17 inches with the B14-0 booster motor Craig provided.

Length: 26.3"
Diameter: 1.04" (ST-10)
Fin Span: 4.04"
Weight: 1.75 oz

B8-0 | B7-6......1,073'......Dv 7 FPS
B14-0 | B2-5........1,143'......Dv 2 FPS
C6-0 | C6-7........1,816'......Dv 23 FPS

Thanks, Steve!

I never thought of the Lune R-1 as a two-stage; that looks really neat.

Coincidently enough I just ordered one, along with a few others I've been meaning get, last night. I had surgery on my right knee yesterday and figured I'll have some time over the next few weeks to put together some easier kits in between Saturn 1B work sessions.
Anyway, to get back on topic, I've taken to leaving room for boosters on the last few clones that I've built (FSI NOVA, Voyager, EOS to name a few) and like Steve thought the Lune R-1 would be a fine candidate as well. As far as an SLS upscale, doesn't Carl make a FSI Black Brant cone?
