Spruce is the most commonly used wood for airplane wing construction. It is a strong, lightweight, and relatively inexpensive wood that is easy to work with. Spruce is also very resistant to rot and decay, making it ideal for use in aircraft that will be exposed to the elements.
Other Woods
In addition to spruce, a number of other woods are also used for airplane wing construction, including:
* Pine
* Fir
* Mahogany
* Birch
* Poplar
These woods are all strong and lightweight, but they are not as resistant to rot and decay as spruce. As a result, they are typically used for aircraft that will be operated in dry climates.
Plywood
Plywood is also a popular material for airplane wing construction. Plywood is made by gluing together thin sheets of wood, which creates a strong and lightweight material that is resistant to rot and decay. Plywood is also easy to work with, making it a good choice for amateur aircraft builders.
