I had a rocket crash yesterday caused by the parachute getting entangled with the shock cord. Very disappointing I worked on it for a long time.
This was a high power H motor launch with a 30 inch parachute and about a 12 foot length of thin Kevlar shock cord.
I have a nomex blanket tied to the shot cord about a foot away from the open end of the body tube. I get the parachute folded up into a burrito bundle in the blanket. Usually I put the remaining length of shock cord loosely in the end of the tube on top of the nomex blanket bundle, put the nose cone on and it’s ready to go. This has worked for me until yesterday.
Any suggestions for preventing the parachute from getting entangled in the shock cord when they are ejected out of the tube?
Is it better for the remaining length of shock cord to go into the tube under the parachute burrito bundle instead of on top of it?
