A semi-cantilever wing relies on which of the following for support?

A semi-cantilever wing design utilizes both internal bracing, such as wing spars, and external support elements, typically in the form of struts, to maintain structural integrity and support the wing's load.

In this type of wing, the internal structure includes strong spars that carry the load and give the wing its shape, while external struts provide additional support. This combination allows for a lighter wing design that can handle aerodynamic stresses while remaining stable during flight. The structural setup reduces the need for more extensive support systems found in fully braced wings, creating a balance that enhances performance characteristics.

This contrasts with wings that rely solely on internal wing spars, which might be limited in their load-bearing capacity and structural efficiency, or those that depend solely on external bracing without internal support. Additionally, wings with no bracing systems at all would not be structurally sound enough to withstand the forces encountered during flight, which makes the semi-cantilever design advantageous.
