The typical structure of the wing is as follows

The wing is one of the most critical parts of an airplane, which can generate lift and enable the airplane to fly in the air. The structure of the wing also directly affects the performance and flight characteristics of the aircraft. Here are some typical structures of wings.

Straight wing

The straight wing is one of the simplest and most common wing forms. Its wing surface is at right angles to the fuselage, with large wingspan and small wing area. The advantages of straight wing are simple structure, low manufacturing cost, good take-off and landing performance and good low-speed stability. However, the aerodynamic performance of the straight wing is poor, the flight resistance is large and the speed is slow.

Trapezoidal wing

Trapezoidal wings are more complicated than straight wings. Its wing surface is flatter than straight wing, and its wingspan is smaller than straight wing. The advantage of trapezoidal wing is that it can provide better lift and aerodynamic performance, and at the same time it can improve flight speed. However, the manufacture of trapezoidal wings is more complicated and the cost is higher.

wing

Wings are wing forms composed of two wings. Its wing surface is V-shaped, and there is a certain angle between its wings. The advantage of biplane is that it can provide better lift and aerodynamic performance, and also has higher stability and maneuverability. But the wing has poor aerodynamic performance and slow speed.

Wingtip wing

The wingtip wing is a relatively novel wing form. Its wing surface is triangular and its wing tip is very sharp. The advantage of wingtip wing is that it can provide excellent aerodynamic performance and improve flight speed at the same time. However, it is difficult to manufacture and install the wingtip wing, and the technical level is high.

In a word, the wing is one of the most critical parts of an airplane. The common wing forms are straight wing, trapezoidal wing, double wing and wingtip wing. Each wing form has its own advantages and disadvantages, and aircraft designers need to choose the most suitable wing form according to their own needs.
