Abstract

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. An attempt to base fuselage drag upon wetted area showed no less scatter than [...] as a function of fineness ratio. For average values of [...] for fuselages and flying boat hulls see Figure 12. The destabilizing effect of fuselages and flying boat hulls based on the volume of a circumscribed cylinder is given in figure 22 as a function of the c.g. position. The fuselage body appears to act somewhat analogous to an airfoil with an aerodynamic center at a point somewhere between the 0.2 and 0.3 body position. The effect of fuselages and flying boat hulls on [...] is given by figures 23 through 29. One set of figures gives [...] as a function of the destabilizing effect and the other set as a function of the c.g. position. No successful means of correlating nacelle data was found. Figures 30 through 33 show the magnitude of nacelle drag and moment effects.
