ABSTRACT:
This is an improvement in circular canopies of the flat, conical, or hemispherical type, some of which have extended skirts with the canopies being of gore construction. External additional gores of porous material cover selected canopy gores and are arranged to insure circular balance of the canopy. Each external gore covering is mounted on radial seams of the canopy gore which it covers beginning at a point above the canopy skirt and extending along the radial seams and across the apex hem to define a compartment for accepting external air flow turbulence existing on the elongated canopy prior to normal inflation. The external gore is closed at the top thereof and incorporates an anti-oscillation vent with the lower end thereof being open and terminating at an elevation of approximately 4 to 14 inches above and in spaced relation to the skirt of the canopy.
