Question 1

What term describes the gradual reduction in wing thickness and/or chord from root to tip?

Accepted Answer

Taper

Answer

Taper refers to the reduction in wing chord and/or thickness from the root to the tip to improve aerodynamic efficiency.

Question 2

A 100% visual inspection of a welded aircraft steel tube fuselage should include checking for:

Accepted Answer

Cracks, dents, and evidence of overheating in the heat-affected zone

Answer

Welded steel tube structures must be inspected for cracks, dents, and heat-affected zone discoloration that may indicate weld failures or structural compromise.

Question 3

What is the correct term for the angle between the wing chord line and the longitudinal axis of the aircraft?

Accepted Answer

Angle of incidence

Answer

The angle of incidence is the fixed angle at which the wing is mounted relative to the aircraft's longitudinal axis.

Question 4

In the damage tolerance design philosophy, what is the primary goal regarding structural cracks?

Accepted Answer

Ensure cracks grow slowly enough to be detected before failure

Answer

Damage tolerance design ensures that if cracks form, they propagate slowly enough to be found during scheduled inspections before causing catastrophic failure.

Question 5

What is the primary structural function of a honeycomb core in a sandwich composite panel?

Accepted Answer

Provide shear rigidity and separate the face sheets

Answer

The honeycomb core resists shear forces and maintains separation between the face sheets, greatly increasing panel stiffness with minimal weight.
