PROBLEM TO BE SOLVED: To provide a body sectional shape designing method, etc., capable of a body in which generated bending moment is suppressed even in the case of the body which becomes an untrue circular shape.SOLUTION: This body sectional shape designing method is for designing a body sectional shape cut by a surface orthogonal to the roll axial direction of a flying object having a body extending in the roll axial direction, and is provided with: the initial setting step S12 of setting an initial sectional shape which becomes an initial sectional shape of a body, the sectional shape of which is an untrue circular shape; load applying steps S14, S21, and S28 of analytically or experimentally applying a pre-pressure load to the body which has the initial sectional shape; and the design shape setting step S17 of acquiring the sectional shape of the body after the pre-pressure load has been applied as a design sectional shape of the body.SELECTED DRAWING: Figure 3
