I working on my L2 rocket, Im almost done
its looking good. The rocket is my own design, dual deploy, 4 dia, MagnaFrame, G10 fins, 78 long, and weighs 125oz, (without motor).
A 60 dia. std chute (Cd .8) brings it down around 20.4 ft/s. (per open rocket)
Im trying to decide on what parachute to buy, and would like some input.
My options are:
60 sunward, octagon, (8 shroud lines) least expensive.
58 topflight, octagon, (8 shroud lines) good reputation mid range cost.
60 Giant leap, round, (16 shroud lines) seems to be heavy duty mid range cost.
58 LOC, round (10 shroud lines) most expensive.
My question is: since the descent rate should be about the same for all of them assuming the Cd is .8), does the shape and number of shroud line make a difference? Would the one with 16 lines tend to get more tangled and less reliable than the one with 8 lines? Would more shroud lines increase the Cd? Anything else I should consider?
By the way, For now I'm not considering the expensive hemi or elipical types now, I may look at those next.
