Aircraft Structural Design - AMT 241 Midterm Review

A set of flashcards covering the key concepts of Aircraft Structural Design from AMT 241 midterm notes.

What is the primary goal in aircraft structural design?

Maximum strength with minimum weight.

What are the four primary forces acting on an aircraft during flight?

Lift, Weight, Thrust, and Drag.

What is the definition of 'Lift' in aviation context?

The upward force that bends the wing spars upward.

What do 'Spars' do in an aircraft structure?

They are the main wing beams that carry bending loads.

How does a 'Monocoque' structure differ from a 'Truss Structure'?

A Monocoque carries most loads through its skin and is lighter but more damage-sensitive, while a Truss Structure is a strong but heavy metal tube framework.

What is meant by 'Safe-Life' in aircraft structural design?

Parts have a fixed service life and must be replaced.

What type of structural failure is caused by repeated stress?

Fatigue cracks.

What does 'Fail-Safe' mean in terms of aircraft safety?

There are multiple load paths, allowing the aircraft to remain safe even if one part fails.

What is 'Corrosion' in the context of aircraft structures?

Chemical damage that weakens metal.

How are 'Ribs' significant in aircraft design?

They provide the airfoil shape and support for the aircraft's skin.
