Seeking the collective wisdom of the group here...
I'm in the process of "toy-bashing" a mini-crayon bank into a
mini-crayon rocket. Starting with the much heavier BT material,
required noseweight for stability and whatever I may do for fin
material, the final product will come in at somewhere from 5 to 8 ozs.
Pretty heavy for a 10 " rocket. Yet, it RockSim's to 1500 ft. on an E
I'd like to use a streamer recovery, but my only experience with
streamers is on rockets is the 2 oz or less range.
1. Are streamers just as effective on heavier model rockets? That is
do they create the same descent rates as on the lighter rockets?
Packages like RockSim and online calculators (EMRR's tools) will
easily calculate a streamer size for a heavier rocket. My assumption
is that if enough surface area is presented by the streamer it will
slow down the descent rate to match that of a lighter rocket. Is that
true in practice?
2. Is there something special about a single streamer? That is if a
streamer is calc'd to yield "X" sq. inches of surface area, is it just
as effective to use 2 streamers each with "X/2" sq. inches of surface
area (all the time maintaining the standard 10:1 ratio of
3. And of course any other pearls of wisdom regarding streamer usage
on heavier rockets is much appreciated.
Thanks in advance.
