Computer-assisted method for optimising surfaces of composite-material structures

Computer-assisted method for designing a composite-material structure with a plurality of components, wherein it includes the following stages:

• a) Providing a multi-cell surface (11) of the structure obtained using aerodynamic calculations;
• b) Transforming said multi-cell surface (11) into an optimised surface (13) with fewer cells,
• concatenating contiguous cells and maintaining point and tangent continuity between them;
• c) Using said optimised surface (13) as master geometry when designing the components of the structure
• wherein
• step b) includes the following sub-stages, in the different zones (40) of the multi-cell surface (11):
• b1) Breaking down each zone (40) of the multi-cell surface (11) itself into the cells (411, . . . , 41n) that comprise it;
• b2) Obtaining the basic surfaces (431, . . . , 43n) of said cells;
• b3) Obtaining surfaces similar (451, . . . , 45n) to said basic surfaces (431, . . . , 43n) with the appropriate grading and segmentation;
• b4) Matching contiguous surfaces (45i, 45j);
• b5) Concatenating contiguous surfaces (45i, 41j) and
• at least one of said steps is performed by a computer processor.
