What are the 4 types of wings?
There are four general wing shapes that are common in birds: Passive soaring, active soaring, elliptical wings, and high-speed wings. The basic elliptical wing shape has disadvantages: The almost uniform lift distribution of a constant-aerofoil section elliptical wing can cause the entire span of the wing to stall simultaneously, potentially causing loss of control with little warning.The elliptical wing is often considered the most aerodynamically efficient planform for minimizing induced drag. Its shape produces an ideal lift distribution across the span.
How does a tapered wing stall?
A highly tapered wing has the opposite problem in that the wing tips will tend to stall first. With swept wings, the tips also tend to stall first. In these cases, aileron effectiveness is reduced by separated flow, and the aircraft often exhibits uncommanded left or right rolls. Tapered wings have an advantage over non-tapered wings. From an aerodynamic standpoint, they have lower drag which allows for faster speeds and a better lift distribution over the surface of the wing.
What are semi-tapered wings?
There are several types of “compound-taper” planforms that are used. The first of these is a wing with a constant-chord center section and tapered outer wing panels. These wings are sometimes called “semi-tapered” (a terminology I personally dislike). This approach is most commonly used on low-wing airplanes. A wing planform in which the chord of the wing changes continuously from the Center of the wing to the wing tip. In addition, this may be accompanied by a taper in the depth of the airfoil.

What is a tapered wing?
Tapered: wing narrows towards the tip. Structurally and aerodynamically more efficient than a constant chord wing, and easier to make than the elliptical type. Trapezoidal: a tapered wing with straight leading and trailing edges: may be unswept or swept. For tapered wings, Taper Ratio = tip chord/root chord.From an aerodynamic standpoint, they have lower drag which allows for faster speeds and a better lift distribution over the surface of the wing. Tapered wings are structurally more efficient with root section, having to support more load, being the section with the largest moment of inertia.Taper ratio is one of the parameters on planform geometry which means the ratio of the root and tip chord lengths of a wing. Hence, its effects on wing’s aerodynamic parameters are also important and should be taken into con- sideration during a wing design process [2] [3].
