Study Notes
Wing Structure Components
- The principal structural members of the wing include spars, ribs, and stringers.
Skin-Stringer Construction
- The skin-stringer construction is a type of aircraft wing structure where the skin (outer surface) is supported by stringers (longitudinal members) that run along the wing's surface.
Spar Direction
- Spars in an aircraft wing run spanwise, meaning they extend from the root of the wing to the tip.
Front Spar Function
- The front spar, also known as the leading edge spar, provides support to the leading edge of the wing and helps to maintain its shape.
Modern Design Concept
- The modern concept used in designing aircraft structures is finite element analysis, which allows for the simulation and optimization of structural designs using computational models.
