Method for optimising the design of manhole openings on an aircraft

摘要

A method for optimising the design of the sealing rings (1) of internal manhole covers (11) which close the manhole openings (12) over the inner surface (13) of the skin (20) of an aircraft structure, the surface that is in contact with the inner surface (13) of the skin (20) being the optimize surface of said sealing rings (10), such that said method comprises the following steps:
- Dividing the outer contour (2) and the inner contour (3) of the optimised surface into n points;
- Grouping into families F i the sealing rings (10) of each manhole opening (12);
- Generating the curves that are best adapted to the set of points taken for the outer contour (2) an for the inner contour (3) of each sealing ring (10) for each one of the families F i ;
- Generating a ruled surface among the curves generate for each one of the families F i .
