The article solves the problem of plotting the bending moment in the plane of the frame for the fuselage of an elliptical cross section by an analytical method. The task considers an elliptical frame, supported by a floor power beam, a moment is calculated at each point and a plot of bending moment is derived for the frame and floor beam.
Keywords: large-capacity fuselages, non-standard fuselage cross-section, elliptical fuselage, non-standard power elements of the frame design, power fuselage floor beam, analytical solution.
