Title:
METHOD OF ATTACHING NACELLE STRUCTURE TO MINIMIZE FATIGUE LOADING
Document Type and Number:
Japanese Patent JP2016172543
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide structural integration of attachments that accommodates a mismatch in the coefficient of thermal expansion (CTE) occurring in a lip skin and a bulkhead and reduces thermally induced fatigue, for nacelle and engine cowlings.SOLUTION: A structural system for accommodating the thermal expansion of a nacelle lip skin 24 and supporting structure has the lip skin 24 and a first angle element 62 attached to the lip skin 24. The first angle element 62 has a free edge 82 that is scalloped to accommodate thermal stresses. A bulkhead 60 is attached to the first angle element 62.SELECTED DRAWING: Figure 5
