Boeing Details Interim 777 Upgrade Studies
By Guy Norris [email protected]
Source: AWIN First
Boeing is evaluating a series of systems, aerodynamic and interior upgrades to the current 777 family at the same time as it aims for potential board approval by year-end for the advanced 777X derivative.
The improvements, ranging from potential drag reduction features and lighter structures and systems to enhanced interiors, are designed to sharpen the 777’s competitive edge while paving the way for a transition to the more ambitious re-winged, re-engined 777X later this decade. The initiative includes leveraging technology developed for the 787 program as well as studies of the potential for retrofitting some elements into the existing fleet.
Possible aerodynamic upgrades include improved seals and gaps, particularly in the wing leading edge, as well as the use of drag-reducing hybrid laminar flow control (HLFC) technology currently under test for possible application on the 787-9. If adopted, the HLFC would be used only on the leading edge of the vertical fin says 777 vice president and chief project engineer Bob Whittington.
