Abstract

Abstract An aircraft having a geometrical means for revolving the nose portion thereof about an axis oblique to the normal centerline of the vehicle, resulting in a pitch-down, nonfaired configuration to increase clear field of vision in the critical area lying below and ahead of the aircraft for landing and takeoff while in one position, and an optimum aerodynamically acceptable supersonic configuration in the other position.

Claim 7
Dependent Claim 135 words
nose member bearing and attachment means comprising nose member bulkhead means positioned in said nose member at least substantially adjacent the aft end thereof and parallel to said nose member base, said bearing and attachment means in cooperative mating relationship with said fuselage bulkhead means so as to be rotationally movably attached thereto, said bearing and attachment means establishing an axis of rotation for said nose member which is oblique to said fuselage centerline, the point of said nose member describing an arcuate path when said member is rotated 180* and establishing a second down vision line relative to the droop of said nose member dictated by said nose member oblique axis of rotation; and C. means attached to one of said first or second portions operative to cause relative rotational movement between said portions.
Claim 8
Dependent Claim 135 words
nose member bearing and attachment means comprising nose member bulkhead means positioned in said nose member at least substantially adjacent the aft end thereof and parallel to said nose member base, said bearing and attachment means in cooperative mating relationship with said fuselage bulkhead means so as to be rotationally movably attached thereto, said bearing and attachment means establishing an axis of rotation for said nose member which is oblique to said fuselage centerline, the point of said nose member describing an arcuate path when said member is rotated 180* and establishing a second down vision line relative to the droop of said nose member dictated by said nose member oblique axis of rotation; and C. means attached to one of said first or second portions operative to cause relative rotational movement between said portions.
Claim 9
Dependent Claim 22 words
a forward fuselage bearing in cooperative operational relationship with said aft fuselage bearing, B. said nose member bearing and attachment means comprises
Claim 10
Dependent Claim 22 words
a forward fuselage bearing in cooperative operational relationship with said aft fuselage bearing, B. said nose member bearing and attachment means comprises
Claim 11
Dependent Claim 25 words
a forward nose member bulkhead positioned in said nose member and defining a forward nose member bearing in operative relationship with said forward fuselage bearing.
Claim 12
Dependent Claim 25 words
a forward nose member bulkhead positioned in said nose member and defining a forward nose member bearing in operative relationship with said forward fuselage bearing.
Claim 13
Dependent Claim 126 words
first and second bulkhead members attached to and forming structural components of said second portion, a. said second bulkhead member displaced forwardly from said first bulkhead member and substantially parallel thereto, b. said bulkheads defining at least in part bearing surfaces in operative relationship with said first portion bearing surfaces, c. said first bearing surface defining a segment of a circle having a center lying on said vehicle centerline and inclined from the perpendicular thereto, d. said second bearing surface defining a segment of a circle inclined from the perpendicular to said vehicle centerline and the center of which, relative to said second portion first bulkhead member, is variable to Said centerline and establishes an axis of rotation of said second portion oblique to said centerline.
Claim 14
Dependent Claim 126 words
first and second bulkhead members attached to and forming structural components of said second portion, a. said second bulkhead member displaced forwardly from said first bulkhead member and substantially parallel thereto, b. said bulkheads defining at least in part bearing surfaces in operative relationship with said first portion bearing surfaces, c. said first bearing surface defining a segment of a circle having a center lying on said vehicle centerline and inclined from the perpendicular thereto, d. said second bearing surface defining a segment of a circle inclined from the perpendicular to said vehicle centerline and the center of which, relative to said second portion first bulkhead member, is variable to Said centerline and establishes an axis of rotation of said second portion oblique to said centerline.
Claim 15
Dependent Claim 165 words
The vehicle defined by claim 2 wherein said means comprises: A. first bearing means integrally attached to said first portion as part of the structure thereof, said first bearing means having an angular relationship to a vertical plane passing through said first portion normal to said centerline, B. second bearing means integrally attached to said second portion as part of the structure thereof, said second bearing means having the same angular relationship to the vertical plane passing through said first portion normal to said centerline as said first bearing means, and coinciding and moveably rotatably mateable therewith, whereby said bearing surfaces establish a rotational axis for said second portion which is oblique to said centerline and defined by the relationship of said bearing surfaces to each other and to said portions to which they are attached, rotational movement of said second portion bearing surface relative to said first portion bearing surface dictating a change in pitchdown of said second portion relative to said first portion.
