Multi segmented recovery

Postby Digit » Sat Jul 15, 2017 5:58 pm

I've been pondering and wanted to ask the builders of the larger, heavier rockets; with exception to the full scale V2; why are the halves/thirds of the rocket still tethered together for recovery instead of coming down separately on smaller 'chutes? Is it just common practice? Is it a rule? Is there an advantage :?:

I think it is easier in some cases to split the recovery. Not sure if it makes any difference to reliability, but it could.

I suspect is is not done so much due to having to find two (or more) parts to the rocket. That's what puts me off. I only need one tracker if they are strung together.

Advantage: One section has no chance of getting a zipper.
Disadvantage: More pieces to recover. Need a chute for each section

Having the sections joined together is more typical, but some kits (eg Quest "Big Rage") are designed for separated recovery

Weight per chute is a big consideration of large, heavy rockets.

Those big chutes are pretty expensive too, so utilising a big chute that you currently use to recovery all of your next largest rocket makes sense.
