Aircraft Construction

Question 1

Material attachment method?

Answer 1

Riveting
 Welding
 Bolting
 Pinning
 Adhesives
Composite fastenerd and bonding

Question 2

Monocoque construction?

Answer 2

Frames to give shape and skin to withstand loads.

Question 3

Semi monocoque construction?

Answer 3

A/c skin provides aerodynamic shape and withstands tension and compression stresses
• Formers/frames: Define the shape and provide skin attachment points.
• Stringers:Run longitudinally and are bonded to the skin. Help withstand buckling
• Longerons:Main longitudinal load bearing members of the fuselage also withstand bending loads
• Bulkheads: Provide structural partitions inside the fuselage and give structural support
• Firewall: A fire resistant bulkhead installed between engine compartment and the rest of the airframe structure

Question 4

For What are used the reinforced shell strictures?

Answer 4

• Outer skin is reinforced by a complete framework of internal members • Weaker areas around windows and doors are reinforced with frames and
stringer sections know as Intercostels • These components are attached of the stressed skin, usually with rivets

Question 5

What is a Machined structure?

Answer 5

Single piece of aluminium forms a skin like stringer structure
