Abstract

Abstract An array of plane mirrors allows forward view of space volumes normally obscured by craft structure without the use of forward facing transparencies. In submerged cockpit aerospace craft, such a system may utilize a deployable upper mirror to reflect such space volumes onto a control mirror for the pilot's use in takeoff and landing operations, allowing the pilot the same visual cues as would be available through a forward facing transparency in front of an apaprent eye position external to the cockpit.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 172 words
A vision augmentation system for a high performance aircraft, comprising: (a) a transparency constructed in a portion of the fuselage of said aircraft at a desired location; (b) an adjustable external mirror positionable at, (i) a stowed position adjacent to said transparency and substantially flush with the outer skin of the fuselage so as to maintain the aerodynamic integrity of the aircraft during high speed flight, and (ii) at least one deployed position for reflecting light received from a field of view exterior to the aircraft, during low speed travel; (c) means for positioning said external mirror; and (d) cockpit mirror means, located internal the aircraft, for receiving light reflected from the external mirror and through the transparency when the external mirror is deployed, said cockpit mirror means being so constructed and arranged to redirect the reflected light toward crewmember of the aircraft thus providing a real-time, three dimensional view from the vantage of an "apparent eye" position located aft of the external mirror, the vision augmentation system preserving depth perception cues.
Claim 2
Dependent Claim 172 words
A vision augmentation system for a high performance aircraft, comprising: (a) a transparency constructed in a portion of the fuselage of said aircraft at a desired location; (b) an adjustable external mirror positionable at, (i) a stowed position adjacent to said transparency and substantially flush with the outer skin of the fuselage so as to maintain the aerodynamic integrity of the aircraft during high speed flight, and (ii) at least one deployed position for reflecting light received from a field of view exterior to the aircraft, during low speed travel; (c) means for positioning said external mirror; and (d) cockpit mirror means, located internal the aircraft, for receiving light reflected from the external mirror and through the transparency when the external mirror is deployed, said cockpit mirror means being so constructed and arranged to redirect the reflected light toward crewmember of the aircraft thus providing a real-time, three dimensional view from the vantage of an "apparent eye" position located aft of the external mirror, the vision augmentation system preserving depth perception cues.
Claim 3
Dependent Claim 17 words
The system of claim 1 wherein said external mirror and said cockpit mirror means are substantially parallel.
Claim 4
Dependent Claim 13 words
The system of claim 2 wherein said cockpit mirror means is angularly adjustable.
Claim 5
Dependent Claim 12 words
The system of claim 3 wherein said external mirror is angularly adjustable.
Claim 6
Dependent Claim 26 words
The system of claim 2 wherein said cockpit mirror means comprises a semi-transparent mirror with associated instrumentation displayed thereon in addition to said field of view.
