Abstract
A retractable airfoil assembly (20) augments the wing surface area (28) of an aircraft (22) enabling it to fly without stalling at reduced speeds during takeoff and landing. The airfoil assembly includes flexible sails (42, 44) and a furling mast (24) for extending and retracting the sails. The furling mast includes a furling drum mounted for clockwise and counterclockwise rotation on a static tube (50). The flexible sail assembly also includes guide tracks (80) located along a leading edge (101) or trailing edge (40) of the wings. The tracks guide the flexible sails during extension and retraction. A drive cable (26) extends and retracts the sails (42, 44) along the guide tracks and maintains tension in the sails while they are extended.
Claims

AMENDED CLAIMS
[received by the Intemational Bureau on 25 September 1998 (25.09.98); original claims 1-21 replaced by amended claims 1-20 (2 pages)]
in claim 12, the sail drive apparatus comprising a rotatable cable drum and a drive cable wound about the rotatable cable drum, the drive cable being attached to the sail.
18. A retractable airfoil assembly as set forth in Claim 12, the sail drive apparatus including a drive cable and plurality of pulleys disposed on the fixed wing structure for guiding the drive cable along the guide track.
19. An extendable/retractable airfoil assembly for selectively increasing the lift surface area of an aircraft of the type including a fixed wing structure comprising: a furling boom including a static tube mounted on the aircraft and a furling drum mounted for rotation on the static tube; a flexible sail coupled to the furling drum; rotary drive apparatus attached to the furling drum for rotating it clockwise and counterclockwise about the static tube; a guide track disposed along an edge of the fixed wing structure; and, drive apparatus coupled to the sail for moving the sail along the track as the sail is furled on or unfurled from the boom.
20. A retractable airfoil assembly for selectively increasing the lift surface area of an aircraft of the type including a fixed wing structure comprising: a furling boom including a static tube
21
mounted on the aircraft and a furling drum mounted for rotation on the static tube; a guide track disposed along an edge of the fixed wing structure; first and second flexible sails coupled to the furling drum and to the guide track; drive apparatus attached to the sails for extending or retracting the flexible sails along the guide track as the flexible sails are furled on or unfurled from the furling boom; and, rotary drive apparatus coupled to the furling drum for rotating it clockwise and counterclockwise.
