The chapter focuses on the design of the fuselage by introducing three elementary fuselage shapes commonly used in aircraft design, the frustum, tubular, and tadpole. The help the designer with the selection of any specific geometry, a range of information on the pros and cons of each is presented. Then, a simple method to sketch a fuselage for a GA aircraft is introduced. While there are many ways to accomplish the initial fuselage sizing, this method forces the CG range and wing position to be considered from the beginning; an approach that quickly reveals unexpected problems with airplane passenger and payload combinations. This is followed by several methods to estimate geometric properties of ...
