What is airplane wing rib?

An airplane wing rib is a structural part of the wing which provides support and shape to the wing. It is located perpendicular to the wing spar, which is the main load-bearing structure of the wing. The wing rib is usually made of lightweight materials such as aluminum or composite materials, and its size and shape vary depending on the design of the wing.

The wing rib has several functions, including supporting the skin of the wing, distributing the weight of the aircraft, and providing rigidity to the wing structure. The spacing between the ribs can also affect the strength and flexibility of the wing.

The design of the wing rib has evolved over time, with modern airplanes using computer models to optimize its shape and placement for maximum efficiency and performance. The use of advanced materials and manufacturing techniques has also led to lighter and stronger wing ribs, allowing for more fuel-efficient airplanes with greater range and payload capacities.
