Packing my parachute

Manoel Victor · Nov 26, 2019

What do you think packing a parachute in a reserved space of 30 cm lenght? The rocket diameter is 13cm. My chute is nylon ripstop and have about 370cm diameter.

how can I find a correct space/volume necessary to packing It? Have any formula?

I don't have a formula, but I think a 370cm (12 foot) chute will fit well in 140 cu. in. of space. You have about 230 cu. in. of space. Sorry for the non-metric numbers. The chute will be loose-fitting. Make sure to wrap it in Kevlar or Nomex to prevent burns. Since it will not fill the entire payload space, it will take a little more pressure to separate the airframe. Make sure you ground test.

When you say Wrap in kevlar, it will be to pack the chute in like in a bag?

I make a custom packing method for each of my rockets and test it on my wind tunnel or with a leaf blower.
