These results are used as a base for the composite wingbox to find the numbers of layers and. Figure 2 shows the structural layout of the Airbus A340 wing, a wing with a similar geometry. Wings may be attached at the top ("high-wing"), middle ("mid-wing"), or lower ("low-wing") portion of the fuselage. Aircraft wing can be considered as a cantilever beam since its root chord is fixed into fuselage with the aid of spars and other end which is also called as tip chord is free. Wings are airfoils attached to each side of the fuselage and are the main lifting surfaces that support the airplane in flight. efficient lightweight structure, meaning, that the volume of the wingbox, the actual load bearing part of the wing has to be maximized.

Find Free Themes and plugins. When positioned above the fuselage (high wings), wings provide an unrestricted view below and good lateral stability. Keywords: Aircraft Design, Structural Analysis . The construction of A major portion of the lift of a heavier-than-air aircraft is developed by the wings. Sgt. S b. Cargo aircraft C-130 (high wing) (Photo courtesy of Tech. These constraints are displayed below in Table 3. The objective of this report is to present the design of the inner wing struc- Want create site? The wingbox is modeled after a commercial transport jet. Introduction . This is clearly illustrated in picture 2.1 where it can be seen that the ribs in the wing are built up as a truss structure. A lot of aerospace structures can be idealised as truss structures. Aircraft Structures for engineering students Fourth Edition T. H. G.
