Wing Design

Each wing design has advantages and disadvantages. By viewing the planform (view from above or below), comparisons in shape and wing aspect ratio can easily be made.

a planform with elliptical wings The elliptical wing is ideal for flight at slow speeds since it has a minimum of drag for a given aspect ratio. But this type is difficult to construct. It would not be a good trainer because it's stall characteristics are not as favorable as a rectangular wing.
The rectangular wing is not as efficient as the elliptical wing. However, it has a tendency to stall first at the wing root (next to the fuselage) which provides stall warning and greater aileron control. a planform with straight rectangular wings
a planform with tapered wings Tapering provides a decrease in drag and increase in lift which is most effective at high speeds. A highly tapered wing has a tendency to stall first slightly inboard of the wingtip. A good compromise for low-speed aircraft is a combination of both rectangular and tapered configurations. The rectangular inboard section provides good stall characteristics and is cost effective. The tapered outboard portion decreases weight and increases aspect ratio.
