Abstract
This work presents an analytical procedure to size the tail and control surfaces of a fixed wing aircraft during the conceptual or preliminary design phases. The objective is to develop a methodology to size these surfaces, from Flight Mechanics theory, with minimal dependence on historical data. The main constrain will come from the type of mission that the aircraft is meant to accomplish and the desired stability characteristics. Since this is an early design procedure, few geometrical data is available and, therefore, simplifications had to be applied. First, from wing aerodynamic data and desirable characteristics for the airplane, is the horizontal tail design. From this step, it is possible to design both the elevator and the vertical tail. Then, regulation restrictions, imposed by aeronautic authorities, drives the aileron’s and rudder’s sizing. Finally, this procedure was incorporated into the conceptual design of a hybrid aircraft; its stability characteristics were evaluated and found satisfactory.
