gnu-parasail
"gnu-parasail" is the idea to
construct one ascending or dirigeable parachute. Here the plant of a model of 16 pannels and with a main
diameter of 26 feet is shown (1 foot = 0,3048 m). The surface
of the model it is of 49,27 m2, sufficient for tire some
pilots-passengers, but not for two-seater. The basis is one parachutes
round of type PDA to the that the
openings f1,f2,f3,f4,f5 and the estabilitzer
ears have been added. It is missing to gauge
the lengths of the lines of suspension about a model at scale. The
suspensions have to connect to on 4 bands (4 lines from band). The center of the
dome connect
him with
two bands on the bands "B".
