42679877, May 19, 1981

Filed:

Mar 29, 1979

Appl. No.:

6/024881

Inventors:

William R. McDonnell - Ladue MO

International Classification:

B64D 500

US Classification:

244 2

Abstract:

This invention pertains to helicopter airborne load systems and composite aircraft configurations. The composite aircraft configurations are designed to allow a fixed wing aircraft to take off and land either vertically or in a short ground run when assisted by a rotary winged aircraft such as a helicopter, and includes a maneuverable probe system used to attach two aircraft to form a composite aircraft configuration, the fixed wing aircraft embodying the use of a receptacle or attachment device cooperative with the maneuverable probe to effect the uniting of the aircraft. The helicopter systems airborne includes the use of the probe to cooperate with special external pods capable of carrying loads, fuel and instrumented devices.

Abstract:

An asymmetric aircraft and an aircraft that can operate from small ships and be stored in high density with three aircraft or more in one helicopter hangar without needing a landing gear or wing fold. These aircraft slide into and out of the hangar on dollies like circuit boards in a computer and are launched and recovered using a large towed parafoil.

International Classification:

B64C 3/10
B64C 30/00
B64C 39/10

Abstract:

An oblique wing aircraft designed for reduced surface area to volume ratio. The aircraft has an oblique wing comprising a forward swept wing segment and an aft swept wing segment. A center oblique airfoil section connects the forward and aft swept wing segments. The center oblique airfoil section has a larger chord near its centerline than the chords of either of the forward or aft swept wing segments. The chord of the center oblique airfoil section tapers down more rapidly than the forward or aft wing segments as the center oblique airfoil section extends outboard toward the forward and aft swept wings. Preferably, the aircraft is an all-wing aircraft.
