Yes, great job on the 3D
And this virtual MiniBoy is exactly as the original (I checked
the rear plate might need a little more support if used with a high mix hybrid.
We discussed that, and I will increase the thickness. It is 1/16" in the drawing, I'll go for 3/16" in aluminum for the back disk.
What are the estimates for sabot weight?
I'll have to build it to answer this one
The 4 "petals" are UHMW 1/4" thick. The front ring and back plate are aluminum.
What advantages do you see this having over a traditional separating sabot?
Easiness of building, and also weight gain regarding other design considered.
This is JSR design BTW
My concern with this is that the massive wind resistance the front plate encounters may "skew" it in flight. since the sabot doesn't separate, this may skew the projectile before it separates.
You might be right
Having the drag on the back plate only could be better. That is easy to solve fortunately, I only have to make a thin ring (like a slice of tubing) instead of a disk in the front, inserted in 4 thin slots. What do you think?
If that's the case, how hard do you (Le Maudit) think it would be to build the sabot like above but in four parts?
Would be a different design. The 4 pieces would need a better drag than a thin edge to be able to separate quickly, it would be impossible to "link" them for rigidity on the front too.
As such, I advocate a 3 or 4 piece separating sabot. This way the sabot begins separation instantly upon exiting the barrel, resulting in very little affect on the round.
The very first design I though about was a similar sabot. But people seem to have success with more simple cup sabots. This design we propose is a cup sabot, as light as possible while keeping some rigidity. It is also relatively easy to build without specialised equipment, with a bit of creativity one can find a disk of the proper diameter and attach 4 petals to it in various materials. I'll go the full machined way of course
If it doesn't work well, it will not go far, the projectile will be easy to retrieve (hopefully!) and it will be time to make another sabot design
I'm thinking the worst thing that could happen to the MiniBoy is a bending of the fins, and I designed then in a way where they can be easily replaced.
