Abstract
An aircraft having variable airframe geometry includes an elongate fuselage having top and bottom sides, a swept back, high-speed wing mounted to the top of the fuselage, and a high aspect ratio, low-speed wing pivotally mounted adjacent to the bottom of the fuselage. The low-speed wing is adapted to pivot between a slow speed flight position in which a longitudinal axis of the low-speed wing is generally perpendicular to a longitudinal axis of the fuselage, and a high-speed flight position in which the longitudinal axis of the low-speed wing is generally parallel to the longitudinal axis of the fuselage. A fairing extends from the fuselage for receiving at least a portion of the low-speed wing when pivoted into the high-speed flight position. The low-speed wing further includes landing gear.

An aircraft having variable airframe geometry, comprising:
- an elongate fuselage having top and bottom sides;
- a swept back, low aspect ratio, high-speed wing fixedly mounted to the top of the fuselage;
- and
- a low-speed wing mounted adjacent to the bottom of the fuselage and pivotable between a slow speed flight position in which a longitudinal axis of the low-speed wing is generally perpendicular to a longitudinal axis of the fuselage, and a high-speed flight position in which the longitudinal axis of the low-speed wing is generally parallel to the longitudinal axis of the fuselage, the low-speed wing comprising a single spar, high aspect ratio wing which, in the slow speed flight position, spans across the fuselage, and, in the high speed flight position, lies adjacent to the bottom side of the fuselage.
An aircraft, comprising:
- an elongate fuselage having top and bottom sides;
- a swept back, low aspect ratio, high-speed wing mounted to the top of the fuselage;
- a single spar, high aspect ratio, low-speed wing mounted adjacent to the bottom of the fuselage;
- means for pivoting the low-speed wing between a slow speed flight position in which a longitudinal axis of the low-speed wing is generally perpendicular to a longitudinal axis of the fuselage, and a high-speed flight position in which the longitudinal axis of the low-speed wing is generally parallel to the longitudinal axis of the fuselage and in which the low-speed wing lies generally adjacent to the bottom side of the fuselage;
- and
- a fairing extending from the fuselage into which at least a portion of the low-speed wing fits when pivoted into the high-speed flight position, wherein the fairing includes a wing tip lock.
An aircraft, comprising:
- a fuselage;
- a high-speed wing fixedly extending from the fuselage;
- and
- a low-speed wing attached to a lower surface of the fuselage and pivotable between a slow speed flight position in which a longitudinal axis of the low-speed wing is perpendicular to a longitudinal axis of the fuselage, and a high-speed flight position in which the longitudinal axis of the low-speed wing is parallel to the longitudinal axis of the fuselage, the low-speed wing comprising a single spar, high aspect ratio wing which, in the slow speed flight position, spans across the fuselage, and, in the high-speed flight position, lies entirely adjacent to the lower surface of the fuselage.
