Now I'm wondering in which orientation a rocket lauch would fly.

What do you think is the flamey end?
leaves
78.1%
roots
21.9%

I was kinda expecting this result. But still I'm not fully convinced. That's because it could cause a lot of complications when you need to turn the lauch rocket around a full 180° from grow to flight configuration. šŸ¤”
Also... now I should try to get wind tunnel test done to compare both configurations!
@ripper I'm still thinking about trans-leak injection :>

@ripper leaves down might look correct, but consider the number of adaptations needed.

For one there would have to be a method of orienting itself upside down.

But also the structure of the nested cylinders breaks open at the top, whereas at the bottom they are nicely nested, which probably works a lot better for a solid fuel rocket!

It's not like those floppy leaves will nicely cradle the flame, there too, the roots are more suitable for this adaptation.

@jasper @ripper it's just that leek isn't a very good rocket in general. If the leaves aren't at the bottom, they will create massive amounts of drag, slowing the rocket down extremely.

@Riedler @ripper with adaptive pressure i am sure the leaves can get more aerodynamic.

The really difficult transition is the material inside becoming solid rocket fuel and igniting it.

@jasper @Riedler at least from the aerodynamic side I could test this, since I should have access to a wind tunnel. However I'm not sure how happy they'll be to have leek leaves in there.
@ripper @Riedler you'd have to keep breeding the plants that do better too, for many generations, maybe better just guess which aerodynamic by eye. Or simulate it in a computer.
@ripper is this in the same family as rocket lettuce?
@ripper
I think you might have a fuel leek.
