Figure 4 shows the typical location of the electrical, bleed air and fre-wire system components on the front spar and leading edge D-nose. Two typical D-nose rib sections are also shown, where the systems pass through the D-nose ribs at the slat tracks.
The electric harness is housed in raceways which connect to the D-nose skin with brackets.
Systems located in the D-nose component also produce access and interface issues.
In addition the fixed jig requires the D-nose to be fixed with pinned arm interfaces, similar to the trailing edge.
Instead of the traditional "D-nose
," says Ticona, the composites have enabled designers to create a more efficient "J-nose." This design allows it to house electrical, de-icing, and other systems.
