Liftoff (FW) build diary

[Liftoff]

I'd prefer to get flips similar to that at 13 seconds

So I was going through the forum and found this flipper calculator (I believe you linked it Mario)
I put the figures in and the result looks good for me, honestly too good.

Just to explain the values in the table, I'm not actually using a 68mm bore ram, but two of 52mm - still that does not matter. I'm using the rams to compress two springs, each rated at 1000kg. The only restriction the springs have is against the exhausting air. (which will exit through a 8mm dia QEV - not much restriction)
The total force of the springs is 2000kg, that's why I used a 68mm ram for the calculation as it gives approx 2000kg of force at 55bar.
The springs compress 38mm so that's the stroke and the flipper arm moves 195mm up, that gives a lever ratio of 5.

The calculated throw of almost 6 metres is impressive, even if it's a theoretical maximum! Wish it would be close to even half that figure!
