strucs mod 4

are airfoils attached to each side of the fuselage and are the main

lifting surfaces that support the airplane in flight.

• Wings
• Airfoils
• Propellers
• Rudders

What are the the 3 wing configurations

• cantilever, semi cantilever, externally braced

• hexaplane, octoplane, quadplane

• octoplane
• monoplane, biplane, triplane

are commonly used by fixed-wing aircraft.

• cantilever

• semi cantilever

• externally braced

• all of the above

Considered to be the strongest wing structure because they are designed so that no

external bracing is needed.

• cantilever

• semi cantilever

• externally braced

• all of the above

They are supported internally by the structural

members and the skin of the plane.

• cantilever

• semi cantilever

• externally braced

• all of the above

usually have one or two supporting wires or struts attached to the wing and the fuselage.

• cantilever

• semi cantilever

• externally braced

• all of the above

is typical of the biplane (two wings placed one above the other) with its struts and flying and landing wires. It either uses struts that act in compression or tension, and/or wires which only act in tension.

• cantilever

• semi cantilever

• externally braced

• all of the above

are used to support the wing and carry

the landing and aerodynamic loads.

• struts

• wires

• braces

• longerons

has two wings placed one above the other

• biplane

• monoplane

• triplane

• quadplane

The internal structure of an aircraft wings is typically made up of stringers and

spars running______

• spanwise

• chordwise

• vertically

• horizontally
