The present invention broadly relates to a tail cone assembly for a helicopter. The tail cone assembly includes a monocoque shell formed from a composite material. The composite material preferably comprises a non-metallic matrix, such as an epoxy resin matrix, having fibers, such as graphite fibers
The present invention broadly relates to a tail cone assembly for a helicopter. The tail cone assembly includes a monocoque shell formed from a composite material. The composite material preferably comprises a non-metallic matrix, such as an epoxy resin matrix, having fibers, such as graphite fibers, embedded therein. The fibers may be oriented along a single axis or along multiple axes. Other components of the tail cone assembly may also be formed from composite materials, which composite materials may be the same as or different from the composite material forming the shell.

A method according to claim 2, and comprising: repeating the steps of scanning the area in the first and second scan directions and of joining the endpoint pixels for at least a second sequence of the pixels on the line having pixel values within the predetermined range, so as to define the respective edges of at least a second one of the stripes; and comparing the edges of at least the first and second stripes to find the stripe pattern in the image. 4. A method for locating a barcode in an image, comprising: dividing the image into a plurality of tiles; scanning each of the tiles so as to detect a pattern of stripes associated with the barcode in at least one of the tiles; analyzing the pattern of stripes so as to determine an angle of orientation of the barcode; and responsive to the determined angle, defining bounds of the barcode that are aligned with the pattern of the stripes, wherein scanning each of the tiles comprises detecting the pattern of stripes in a first one of the tiles, and wherein defining the bounds of the barcode comprises seeking the bounds of the barcode in at least a second one of the tiles, adjacent to the first one of the tiles. 5. A method according to claim 4, wherein scanning each of the tiles comprises scanning so as to detect the pattern of stripes substantially irrespective of the angle of orientation of the stripes.6. A method according to claim 4, wherein the stripes have respective ends, and wherein defining the bounds of the barcode comprises locating the ends of the stripes and delimiting a rectangle containing the barcode and having sides defined by the ends of the stripes.7. A method according to claim 4, and comprising reading the barcode responsive to the bounds.8. A method for locating a barcode in an image, comprising: dividing the image into a plurality of tiles; scanning each of the tiles so as to detect a pattern of stripes associated with the barcode in at least one of the tiles; analyzing the pattern of stripes so as to determine an angle of orientation of the barcode; and responsive to the determined angle, defining bounds of the barcode that are aligned with the pattern of the stripes, wherein the stripes have respective ends, and wherein defining the bounds of the barcode comprises locating the ends of the stripes and delimiting a rectangle containing the barcode and having sides defined by the ends of the stripes, wherein defining the bounds of the barcode comprises finding extreme lines of the barcode corresponding to first and last ones of the stripes of the barcode, and wherein locating the ends of the stripes comprises scanning along at least some of the stripes intermediate the first and last stripes in a direction parallel to the extreme lines. 9. A method for finding a pattern of parallel stripes in an image, which comprises a plurality of pixels having respective pixel values, the method comprising: scanning an area of the image along a selected scan line in a first scan direction so as to locate a first sequence of the pixels on the line having pixel values within a predetermined range; starting from each of at least some of the pixels in the sequence, scanning in a second scan direction, transverse to the first scan direction, to both sides of the line, so as to reach endpoint pixels defined by the first of the pixels on both sides of the line having pixel values outside the predetermined range; joining the endpoint pixels on each side of the line to define respective edges of a first one of the stripes; repeating the steps of scanning the area in the first and second scan directions and of joining the endpoint pixels for at least a second sequence of the pixels on the line having pixel values within the predetermine
