Abstract:
1. A method of designing an aircraft component formed by a number of elements (j), including a phase to estimate the effect of a variation of a design variable on the component weight, said method comprising the following steps: a) providing main primary structure basic data of the aircraft component and Reserve Factors (RFij) associated to its design criteria (i); b) obtaining a breakdown of the component weight by said design criteria (i); c) obtaining the weight effect of a design variable variation, wherein step b) includes a sub-step for assigning a fictitious weight (mefRFij) to each element design criteria (i) as a function of the weight (meaj) of each element (j) and of a parameter (n) able to determine which criteria from RF>1 can be considered without effect on weight according to the following equation: d) manufacturing an aircraft component, based on the method above.
