Claim:
A ram air inflated wing, comprising: an upper wing surface and a lower wing surface constructed from a flexible material, the upper and lower surfaces being joined along their edges to form an envelope having a leading edge and a trailing edge; a plurality of flexible material walls disposed, substantially in a direction parallel to airflow, between the upper and lower surfaces to form a plurality of cells within the envelope; one or more openings, substantially at or near a flow stagnation point such that air can enter and inflate the envelope; at least two flying lines for restraining and controlling the wing; wherein: at least one of said flying lines is attached either directly or indirectly to or near to each respective end of the envelope; the wing is bridleless over the entire span of the wing apart from tips of the wing; and the outer sections of the wing create aerodynamic forces which maintain a generally arc shaped spanwise horizontal form of the wing while flying.
