Abstract:
Some factors affecting the design of a row of windows in a pressurized cylindrical fuselage are discussed. The concept of the neutral hole is adopted, but account is taken of the change in the basic 2:1 stress field occasioned by the presence of stringers, frames, longerons and, in particular, reinforced strips surrounding the windows and running the length of the fuselage. The influence of such reinforcement is to make the shape of the neutral hole slightly more circular than the standard √/2:1 ellipse. Results are presented in graphical form.
