Abstract
Abstract Jet aircraft having means for deflecting the thrust thereof for control purposes. Deflecting means are normally received into a suitable recess in structure adjacent the jet stream such as the horizontal stabilizer, the vertical stabilizer or the fuselage rearward of the jet output. Same are then actuated by any conventional means to extend the deflectors into the jet stream during slow speed operation of the aircraft and retracting same to permit during high speed operation of the aircraft all control functions to originate with the stabilizers, elevators and rudder. A further feature of the invention contemplates mounting the deflectors in a component movable with respect to the jet output, such as the elevators, with the elevators normally located below the jet output whereby the deflectors can be extended without entry into the jet stream at substantially level flight but will move gradually into the jet stream as said elevators are lifted during a landing operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
In an airplane having a vertical tail surface and a horizontal tail surface and means for supporting a jet engine adjacent said horizontal tail surface, said jet engine producing a gaseous stream for propelling said airplane, the combination comprising: deflection means for deflecting said gaseous stream, said deflection means including surface means and support means for supporting said surface means for pivotal movement between first and second positions about an axis which is substantially perpendicular to said horizontal tail surface; and storage means on said horizontal tail surface for storing said surface means in said first position, said surface means being pivotable about said support means to said second position wherein said surface means is adapted to contact and deflect said gaseous stream.
Claim 2
Dependent Claim
123 words
In an airplane having a vertical tail surface and a horizontal tail surface and means for supporting a jet engine adjacent said horizontal tail surface, said jet engine producing a gaseous stream for propelling said airplane, the combination comprising: deflection means for deflecting said gaseous stream, said deflection means including surface means and support means for supporting said surface means for pivotal movement between first and second positions about an axis which is substantially perpendicular to said horizontal tail surface; and storage means on said horizontal tail surface for storing said surface means in said first position, said surface means being pivotable about said support means to said second position wherein said surface means is adapted to contact and deflect said gaseous stream.
Claim 3
Dependent Claim
29 words
The combination according to claim 1, wherein said surface means has an outer contour conforming to the outer contour of said horizontal tail surface when in said first position.
Claim 4
Dependent Claim
47 words
The combination according to claim 2, wherein said surface means is located on the trailing edge of said horizontal tail surface and wherein said storage means comprises a recess of appropriate size in said horizontal tail so that said surface means is flush with said trailing edge.
Claim 5
Dependent Claim
79 words
The combination according to claim 3, wherein said horizontal tail surface is located below the axis of said gaseous stream so that when said horizontal tail surface is in a neutral position and said surface means is swung into said first position, said surface means is free of contact with said gaseous stream and when said horizontal tail surface is at said second position, said surface means is in the position of greatest deflection effectiveness or said gaseous stream.
Claim 6
Dependent Claim
65 words
The combination according to claim 4, wherein said airplane has a pair of thrust nozzles side-by-side and wherein said horizontal tail surface has a pair of surface components, said storage means storing one of said surface means on each of said surface components of said horizontal tail surface, each of said surface means being pivotal about an axis substantially perpendicular to said horizontal tail surface.
Claim 7
Dependent Claim
113 words
In an airplane having at least a vertical tail and means for supporting a jet engine, said jet engine producing a gaseous stream at an outlet nozzle for propelling said airplAne, the combination comprising: surface means positioned adjacent said outlet nozzle; support means for supporting said surface means for pivotal movement between a first position of use and a second stored position about a substantially vertical axis parallel to said vertical tail and which is substantially perpendicular to said surface means, said surface means being adapted to contact said gaseous stream to deflect same when in said first position of use and stored in a position of nonuse when in said second position.
Claim 8
Dependent Claim
113 words
In an airplane having at least a vertical tail and means for supporting a jet engine, said jet engine producing a gaseous stream at an outlet nozzle for propelling said airplAne, the combination comprising: surface means positioned adjacent said outlet nozzle; support means for supporting said surface means for pivotal movement between a first position of use and a second stored position about a substantially vertical axis parallel to said vertical tail and which is substantially perpendicular to said surface means, said surface means being adapted to contact said gaseous stream to deflect same when in said first position of use and stored in a position of nonuse when in said second position.
Claim 9
Dependent Claim
46 words
Aircraft according to claim 6, wherein said airplane has a pair of jet nozzles side-by-side on opposite sides of a tail cone that extends rearwardly of said nozzles and wherein said surface means each is swingable out of the tail cone sideways into said gaseous stream.
