Abstract

An in flight damage assessment and surveillance system for aircraft using imaging apparatus for capturing optical images of predetermined portions of the aircraft disposed along the exterior of said aircraft in a manner such that the flight characteristics of the aircraft remain substantially unaltered. The images captured are recorded on a storage media mounted within the aircraft and having an enclosure which provides for the survival of the storage media even when subjected to the harsh environment of an aircraft crash. A display for displaying the captured optical images to aircraft crew members is also positioned within the aircraft along with apparatus for interfacing the imaging apparatus to recording apparatus and the display. The system can also include second imaging apparatus for capturing optical images of selected portions of the interior of the aircraft as well as a telemetry device for transmitting images to or from ground based stations.

Claims

1. An in flight damage assessment and security system for aircraft comprising:

imaging means for capturing optical images of predetermined portions of said aircraft substantially continuously during flight, being disposed along the exterior of said aircraft such that the flight characteristics of the aircraft remain substantially unaltered, said imaging means comprising;

a plurality of video cameras positioned on the structure of said aircraft and positioned to view a first and a second side of a vertical stabilizer, an upper side of a fuselage and two aircraft wings, a front landing gear under carriage portion and an aft underbody portion of said aircraft, including an underside of said wings;

means for recording images captured by said imaging means on a storage media, said recording having an enclosure which provides for the survival of said storage media even when subjected to the harsh environment of an aircraft crash;

display means for displaying said captured optical images to aircraft crew members; and

means for interfacing said imaging means to said recording means and said display means.

2. The damage assessment system of claim 1 further comprising telemetry transfer means for transmitting said captured optical images to one or more remote receiving stations.

3. The damage assessment system of claim 2 wherein said telemetry transfer means further comprises means to transfer optical images from one or more ground stations to said interfacing means.

6. The system of claim 1 further comprising:

second imaging means for capturing optical images of predetermined portions of said aircraft being disposed within the interior of said aircraft so as to be substantially unseen by aircraft passengers; and

telemetry transfer means for transmitting said captured optical images to one or more receiving stations remote from said aircraft.

7. The system of claim 6 wherein said optical images captured by said second imaging means comprises

a view of each predetermined passenger class section of which said aircraft interior is divided into;

each point of ingress or egress used for passenger entry or exit; and

interior pathway used for cargo loading and any restroom areas located within said interior.

4. An in flight damage assessment system for aircraft comprising:

imaging means for capturing optical images of predetermined portions of said aircraft substantially continuously during flight, being disposed along the exterior of said aircraft such that the flight characteristics of the aircraft remain substantially unaltered, said imaging means comprising;

a first video camera mounted within an outer portion of a first wing structure so as to focus on a first side of an aft tail section from a first wing;

a second video camera mounted within an outer portion of a second wing structure so as to focus on a second side of said aft tail section from a second wing;

first and second optical windows positioned adjacent said first and second video cameras so as to preserve the airfoil shape of said first and second wings comprising substantially optically transparent material;

means for recording images captured by said imaging means on a storage media, said recording having an enclosure which provides for the survival of said storage media even when subjected to the harsh environment of an aircraft crash;

display means for displaying said captured optical images to aircraft crew members; and

means for interfacing said imaging means to said recording means and said display means.

5. The system of claim 4 further comprising;

a third video camera mounted within a leading edge of a vertical stabilizer so as to focus on a predetermined portion of said first and second wings including a trailing edge and a portion of a leading edge for each of said wings.

8. A method of providing in flight damage assessment for an aircraft while in atmospheric flight comprising the steps of:

disposing imaging means for capturing optical images of predetermined portions of said aircraft along the exterior of said aircraft such that the atmospheric flight characteristics of the aircraft remain substantially unaltered;

capturing optical images of predetermined portions comprising first and second sides of vertical stabilizers, upper fuselage and wing surface, front landing gear under carriage and aft underbody including underside wing surfaces;

providing recording means for recording optical data on a storage media, said recording means having an enclosure capable of protecting said media even when subjected to the harsh environment of an aircraft crash;

securing said storage means within said aircraft;

providing display means for visually displaying at least one image of said captured optical images to aircraft crew members; and

interfacing said imaging means to said recording means and said display means.

9. The method of claim 8 further comprising the steps of:

capturing a first set of optical images of predetermined portions of an exterior of said aircraft using first imaging means disposed on said aircraft;

capturing a second set of optical images of predetermined portions of an interior of said aircraft using second imaging means disposed on said aircraft; and

transferring said first or second set of images to at least one image receiver located external to said aircraft through a telemetry transceiver.

10. The method of claim 8 further comprising transferring said captured optical images to at least one remote receiver located external to said aircraft.

11. The method of claim 8 further comprising the steps of

capturing a third set of optical images of predetermined portions of aircraft landing areas and approaches thereto taken from a plurality of remotely, land based cameras;

transferring said third set of images to said display means through a telemetry transceiver for viewing while said aircraft is still in flight.
