[Figure 2-5] The most popular types of fuselage structures used in today's aircraft are the monocoque (French for "single shell") and semimonocoque. These structure types In this text, a small aircraft is one designed to carry one to ten people (e.g. 14 CFR Part 23, normal, utility, and aerobatic categories, or similar). Such aircraft are generally powered by piston or turbine engines, swinging 2- to 4-bladed propellers, although some are also driven by jet engines.

Design of Aircraft. 2003 Pearson the part of the drag polar that is most useful for the design purpose, i.e., positive lift side. From the fitting process just described above it is found that the best fit to 2D airfoil drag polar data is obtained for %, â L0.0145 ; L0.0664; %, 40.4 and the corresponding fitting curve of Eqn. (2) is shown in Fig, 1b with dashed line. The aircraft is a two-seater model, oriented towards fast and economic travelling. For this purpose, the development of the wings, the propeller and fuselage has been done with extra caution, in order for us to achieve the best results possible.

There are a number of generally accepted stages in the design, development, manufacture and operation of aircraft, each with associated design methods and data requirements. These are shown schematically in Fig. 1.2, which also shows how the modern practice of concurrent engineering has reduced the overall timescale from conception to service. Wing Design There were 3 choices for the types of wing that we could use. Elliptical Figure 1:Elliptical Wing The elliptical wing o ers a number of advantages in that it produces the minimum induced drag for a given aspect ratio. Additionally, an elliptical wing also happens to be well suited for he
