Bottle Flip Scott manley video...

[Arugela]

I just ran into this randomly on youtube....

I don't know if he watches these forums so he probly won't see this, but I think his problem was the shape of the cargo bay. The bottoms do not have full curves like the top. So, for instance, when he flipped on the back it still flipped over because when it went sideways it was more likely to roll because the top is fully curved while the top has a flat bottom. so it always moved when possible to the top because the cargo could move more. It also makes it less likely to move from the top. so when it is on it's top opening it is not going to unroll from the top... Plus it may flip that way because the palyload can lean farther in that direction over even the other 3 flat side... I think he needs MK2 or a modded MK3 with a different shape.

 

I thought this was interesting.I never noticed this before. Probably because cargo is usually held down...

 

Edit: I just noticed this was a challenge.. Is there a better forum to put this into? Is the challenge still going?

 

I guess I should add I don't know what the bottle flip thing is. I'm assuming a science experiment. Am I missing something and it flipping on it's head what it is supposed to demonstrate?

As I understand it, the point is how sloshing inside affects the rotation rate of the main craft.

Except that in this case he never had anything capable of sloshing around inside the cargo bay.  A pile of 50 small stack separators would have been my first choice, although those smaller beachball tanks may have been better.

 

Also, I expected the challenge to be an open-ended bottle with the goal being to flip it 180 without spilling any cargo
