These dimensions are reference information only. Adjustment may be necessary, based on construction variances, line age/shrinkage, etc. However, they should proved a good place for the various components.
Dimensions listed for lines are finished lengths and are measured from end loop to end loop after tying knots. Parachute centering and confluence line lengths are measured under nominal 3-5lbs tension.
Balloon volume 54,000 cubic feet
Diameter at equator 49 feet
Diameter at mouth approximately 10 feet
Parachute top constructed diameter 18' 1"
Parachute activation/deflation line 63' 0"
Deflation line routing ring, bridle lines 4' 0" (quantity 2)
Parachute confluence lines 11' 7" (quantity 16)
Parachute centering lines 6' 10" (quantity 16)
Parachute retrieval cord 14' 0"
Crown line 82' 0"
All lines are installed using the bowline knot. The finished bowline knot should have a loop approximately 1.5" long. The amount of cord (to be added to finished lengths listed above) required to tie a bowline of this finished dimension is approximately 10".
