At the wing root, the flow over the wing and the flow over the fuselage must merge smoothly to avoid premature flow separation, which can cause early stall and increase drag. The position of the wing affects the interaction between the wing and the fuselage most strongly. low-wing decision affects multiple areas: Aerodynamics There are other configurations such as mid-wing designs, parasol wings, and biplanes, but we will defer our discussion of these to another time. The majority of airplanes have the wing attached to either the top of the fuselage or the bottom. To begin, I am going to limit the discussion to high-wing vs. These are actually decided during the preliminary layout of the airplane, but since I did not cover them explicitly in our discussion of layout, we will start our look at wing design here. In the context of wing design there are two primary choices to be made: the vertical position of the wing (high wing, mid wing, or low wing) and the structural concept (cantilever or braced). The first major decision the designer makes after preliminary sizing is the overall configuration for the airplane.

We will not revisit them now but will, over the next few months, consider the other factors that go into the final wing configuration. Although they might change a little as the design goes through multiple iterations, they are essentially set.
Placement of the wing (high, mid or low)Īt this point in the design, wing area and wing loading have already been addressed in the sizing process.
#Airplane wings series
The designer has a series of things to decide to arrive at a complete wing design. We already have a preliminary layout of the airplane, so we can now start designing the wing in more detail.
It’s now time to move on to fleshing out details of the configuration. At this point in the design process, we have gotten the airplane sized, balanced, and after six months of consideration gotten the landing gear right.
