Abstract
Abstract A cargo aircraft. A non-pressurized hull, which can comprise a number of substantially identical hull modules, defines a rectangular cargo area. The hull has an outer skin portion which, in its vertical, longitudinal section, conforms to an air foil shape. This air foil configuration generates substantially all the lift necessary to offset the combined weights of the hull and a reasonable load. The hull supports wings, engines and a pressurized cabin for an operating crew and other elements necessary for operating the aircraft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
An aircraft comprising: A. a hull having a roll axis and including a plurality of juxtaposed hull modules, each module including: i. a planar cargo support means extending substantially throughout the length and width of the hull module, ii. an external covering surrounding said cargo support means, said covering means constituting an airfoil in the vertical cross sections parallel to the roll axis and being substantially rectangular in cross sections normal to the roll axis to thereby provide a substantially structurally unobstructed cargo space above said support means throughout said hull module, said hull module generating a lift in flight which substantially offsets the combined weight of said hull module and the cargo it carries, B. wings connected to said hull, C. means for controlling the aircraft in flight connected to said hull and wings, D. means for powering the aircraft, and E. a fuselage connected to an upper portion of said hull to be completely above said cargo space in one of said hull modules.
Claim 2
Dependent Claim
166 words
An aircraft comprising: A. a hull having a roll axis and including a plurality of juxtaposed hull modules, each module including: i. a planar cargo support means extending substantially throughout the length and width of the hull module, ii. an external covering surrounding said cargo support means, said covering means constituting an airfoil in the vertical cross sections parallel to the roll axis and being substantially rectangular in cross sections normal to the roll axis to thereby provide a substantially structurally unobstructed cargo space above said support means throughout said hull module, said hull module generating a lift in flight which substantially offsets the combined weight of said hull module and the cargo it carries, B. wings connected to said hull, C. means for controlling the aircraft in flight connected to said hull and wings, D. means for powering the aircraft, and E. a fuselage connected to an upper portion of said hull to be completely above said cargo space in one of said hull modules.
Claim 3
Dependent Claim
19 words
An aircraft as recited in claim 1 wherein said fuselage means is pressurized and said hull modules are unpressurized.
Claim 4
Dependent Claim
25 words
An aircraft as recited in claim 1 wherein each hull module includes access means for opening the cargo space therein for loading and unloading cargo.
Claim 5
Dependent Claim
35 words
An aircraft as recited in claim 3 additionally comprising fuselage means mounted to one of said hull modules to an upper portion thereof, said access means for the hull module extending beneath said fuselage means.
Claim 6
Dependent Claim
24 words
An aircraft as recited in claim 3 wherein said access means comprises at least one door on a leading edge of said hull module.
Claim 7
Dependent Claim
212 words
An aircraft comprising: A. a hull having a roll axis and including: i. planar cargo support means running substantially throughout the length and width of said hull, ii. an external covering means surrounding said cargo support means, said external covering means constituting an airfoil in the vertical cross sections parallel to the roll axis and being substantially rectangular in the corss sections normal to the roll axis along subsTantially all of the roll axis to thereby provide a substantially unobstructed cargo space above said support means throughout the length of said hull, said hull generating a lift in flight which substantially offsets the combined weight of said hull and the cargo it carries, and iii. access means including door means traversing a leading edge of said hull, said door means in an open position exposing substantially the entire width of said cargo space across said hull and in a closed position constituting an integral portion of the leading edge of the airfoil formed by said external covering means, B. wings connected to said hull, C. means for controlling the aircraft in flight connected to said hull and wings, D. means for powering the aircraft, and E. a fuselage means mounted to a hull portion to be completely above said cargo support space.
Claim 8
Dependent Claim
212 words
An aircraft comprising: A. a hull having a roll axis and including: i. planar cargo support means running substantially throughout the length and width of said hull, ii. an external covering means surrounding said cargo support means, said external covering means constituting an airfoil in the vertical cross sections parallel to the roll axis and being substantially rectangular in the corss sections normal to the roll axis along subsTantially all of the roll axis to thereby provide a substantially unobstructed cargo space above said support means throughout the length of said hull, said hull generating a lift in flight which substantially offsets the combined weight of said hull and the cargo it carries, and iii. access means including door means traversing a leading edge of said hull, said door means in an open position exposing substantially the entire width of said cargo space across said hull and in a closed position constituting an integral portion of the leading edge of the airfoil formed by said external covering means, B. wings connected to said hull, C. means for controlling the aircraft in flight connected to said hull and wings, D. means for powering the aircraft, and E. a fuselage means mounted to a hull portion to be completely above said cargo support space.
