Longitudinal beam (also known as long longitudinal beam) is a relatively slender member in the longitudinal direction, which is connected with the skin and plays the role of supporting the skin. Generally, it is also connected with the wing rib and supported by the wing rib. The longitudinal beam is one of the important stressed members in the longitudinal skeleton, which bears the axial force generated by the wing bending moment and the shear force generated by the local aerodynamic force. The magnitude of these forces depends on the structural form of the airfoil and determines the cross-sectional shape and area of the longitudinal beam.

According to the shape of the notch, the beam has open section and closed section, and according to the manufacturing method, there are plate bending beam and extrusion beam. The airfoil is smooth and easy to fix on the skin and other parts. Bending the closed contour of the plate can increase the critical stress of the contour and skin compression. The web of extruded profile is usually thicker than that of plate bending profile. Under the same other conditions, its critical stress is high, but it is difficult to fasten with the skin (especially the skin with large curvature).

The wing beam is composed of the web and edge (or flange) of the beam, most of which are fixed at the root with the middle wing section or with the fuselage, and the section is I-shaped or groove shaped. The beam is a simple stressed member, and the side bears the bending moment M. Axial force caused by tension and compression. The web reinforced by the column bears the shear force Q and can bear the shear flow caused by the moment Mt,

In both cases, the periphery of the airfoil is closed and sheared. In some structural forms, it is the main longitudinal load-bearing member of the airfoil, bearing all or most of the bending moments of the airfoil.

Sandwich box structure is mainly for airfoils with relatively small thickness. The inner plates of the upper and lower sandwich skins are too close, resulting in full thickness sandwich or full filled sandwich structure. It is a sandwich box wing filled with foam. In this structure, there are no other ribs except the tip and root of the wing. The upper skin is supported by the lower skin through the core, with high stress level and light structural weight; However, this structure cannot be loaded internally, and is generally used for unloaded outer wing structures.

Due to different speeds and aircraft types, wings generally have many different plane shapes, including straight wings, swept wings and delta wings. For example, straight wings are mainly used for low-speed aircraft, swept wings are mainly used for high subsonic and supersonic aircraft, delta wings and small aspect ratio straight wings are used for supersonic aircraft.

Large aircraft model manufacturers remind you that different types of airfoils usually use different forms of airfoil structures. Even for the same type of flat profile, its structural form will vary according to specific design requirements.

Judging from the airfoil structure of modern aircraft, thin skin beam structure is rarely used. Large high subsonic modern transport aircraft and some supersonic fighters adopt multi beam integral structure; Supersonic fighters with large Mach number usually adopt multi wall (or multi beam) wing structure or hybrid structure. For example, the part to be perforated at the root adopts the beam type, and the thin outer end adopts the single block type to increase the stiffness.
