Wrapped-cone fingers for use in an air-cushion vehicle (ACV) skirt system
are described. Wrapped-cone fingers may include an inner cone that is
"wrapped" or generally enclosed by an outer finger. The inner cone may
include an inner cone opening through which air may travel. The outer
cone may include a back face opening. When inflated, the inner cone
blocks the back face opening in the outer finger, allowing for increased
air pressure in the outer finger and thus inflating the inner cone and
outer finger of the wrapped-cone finger. Wrapped-cone fingers according
to the present invention may be lightweight, inexpensive and resistant to
scooping and snagging. Embodiments are also directed to ACV skirt systems
and methods of manufacturing wrapped-cone fingers for use with an ACV
skirt system.
