DESIGN METHOD, DESIGN DEVICE, AND DESIGN PROGRAM FOR CROSS-SECTIONAL SHAPE OF FUSELAGE

摘要

A method for designing the cross-sectional shape of the fuselage of a flying body having the fuselage extending in the roll axial direction, the section being taken on a plane perpendicular to the roll axial direction. This method is provided with: an initial setting step S12 for setting an initial cross-sectional shape, which is the initial cross-sectional shape of the fuselage having a cross-sectional shape that is not truly circular; load application steps S14, S21, S28 for analytically or experimentally preloading the fuselage having the initial cross-sectional shape; and a design shape setting step S17 for acquiring the cross-sectional shape of the preloaded fuselage as the design cross-sectional shape of the fuselage.
