Research

A Brief History of Aircraft Structures

Early aircraft used a welded steel tubing fuselage truss for structural strength.
The monocoque design emerged, using a stressed-skin structure for a streamlined shape and lighter weight.
Monocoque designs incorporated thin aluminum-alloy sheets for the exterior.
Semi-monocoque construction techniques were developed to address the weakness of monocoque designs, incorporating a sub-structure to distribute loads.

Major Structural Stresses

The wing spars are designed to flex and carry bending loads, ensuring the wing can bend upward from the root towards the tip.
Compression ribs (struts) are used to strengthen the spars and help carry compressive loads.
Wing spar designs have evolved from wood to extruded aluminum alloy for modern aircraft.

Wing Construction

Laminated spars use glued strips of wood with the grain running in the same direction for strength.
Supersonic aircraft sometimes utilize stainless steel skins brazed to a honeycomb core for added strength.
Control surfaces are often covered with thin aluminum or magnesium alloy sheets, or advanced composite materials.

Control Surface Construction

Flutter is a significant design consideration for control surfaces, referring to the uncontrolled oscillating movement that can occur in the airstream.
Control surfaces are often statically balanced to prevent flutter, and require rebalancing after repairs or modifications like painting.
Corrugation is used on control surfaces to increase surface rigidity and reduce weight by minimizing substructure needs.
