Question 1

What is the function of a web in an aircraft wing spar?

Accepted Answer

To carry shear loads between the spar caps

Answer

The spar web primarily carries vertical shear loads, transferring them between the upper and lower spar caps.

Question 2

When inspecting a composite structure for delamination, which non-destructive testing method is most effective?

Accepted Answer

Ultrasonic C-scan inspection

Answer

Ultrasonic C-scan inspection is the most effective NDT method for detecting internal delamination in composite laminates.

Question 3

What type of corrosion forms between two dissimilar metals in contact with an electrolyte?

Accepted Answer

Galvanic corrosion

Answer

Galvanic corrosion occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, causing the anodic metal to corrode.

Question 4

Which alloy designation series indicates aluminum alloyed primarily with zinc?

Accepted Answer

7000 series

Answer

The 7000 series aluminum alloys use zinc as the primary alloying element, producing the highest-strength aluminum alloys.

Question 5

What is the primary advantage of a geodesic (geodetic) airframe construction?

Accepted Answer

High strength-to-weight ratio with redundant load paths

Answer

Geodesic construction uses interlocking diagonal members that create a very high strength-to-weight ratio with multiple redundant load paths.
