What are the two primary uses for plywood in aircraft construction?

Plywood serves multiple purposes in aircraft construction, with two primary uses being gusset plates and aircraft skin.

Gusset plates are reinforcement components that help to strengthen joints and provide additional support at various structural points in the airframe. Plywood is chosen for its strength-to-weight ratio and its ability to distribute loads effectively, making it ideal for these applications.

As for aircraft skin, plywood can be used to create a smooth, aerodynamic outer covering on certain aircraft structures. It provides both structural integrity and the ability to carry loads while maintaining a lightweight profile. The properties of plywood, such as its resistance to warping and ease of manufacturing into complex shapes, make it suitable for these critical components.

These uses highlight plywood's versatility and effectiveness in contributing to aircraft strength and durability, essential qualities in aviation safety and performance.
