Question: What is a bag skirt?

The bag skirt is basically just that... a bag. The bag skirt should
probably be called a tube skirt because it consists of a tube that
encircles the perimeter of the craft. The bag is inflated which
serves to lift the craft off the ground and more importantly, to
contain the air cushion. There are two methods of inflating the bag
skirt, the first being serial feed and the second being parallel
feed. The serial feed method requires that air be directed from the
lift fan _through_ the skirt and then out into the cushion. The
parallel feed method requires that a certain amount of air be split
off of the lift fan into the skirt (about 10%) and the rest into the
cushion.
