Aircraft Assembly

Question 1

involves the joining of various components and
structures that form an entire aircraft

Answer 1

Aircraft assembly

Question 2

generally refers to the positioning and alignment of an aircraft’s major sub-assemblies to
produce a synergistic design.

Answer 2

rigging

Question 3

five major stresses to which all aircraft are subjected

Answer 3

• Tension
• Compression
• Torsion is the stress that produces twisting.
• Shear
• Bending stress

Question 4

is the stress that resists a force that tends to pull something apart

Answer 4

Tension

Question 5

is the stress that resists a crushing force.

Answer 5

Compression

Question 6

occurs to thin sheet materials when they are subjected to end loads and to ties if
subjected to compressive forces.

Answer 6

Buckling

Question 7

is a phenomenon that occurs in a member that is under compression with sufficiently short length to prevent instability

Answer 7

Crippling

Question 8

is the stress that resists the force tending to cause one layer of a material to slide over an adjacent layer.

Answer 8

Shear

Question 9

is a combination of compression and tension.

Answer 9

Bending stress

Question 10

Major categories of aircraft

Answer 10

airplane, rotorcraft, glider, and
lighter-than-air vehicles.

Question 11

the main structure or body of the fixed-wing aircraft. It provides space for cargo, controls, accessories, passengers, and other equipment

Answer 11

Fuselage

Question 12

A —— is a rigid framework made up of members, such as beams, struts, and bars
to resist deformation by applied loads.

Answer 12

truss

Question 13

The truss-framed fuselage is generally
covered with _______.

Answer 13

fabric

Question 14

The ________ fuselage relies largely on the strength of the skin or covering to carry the primary loads.

Answer 14

monocoque (single shell)

Question 15

The true monocoque construction uses _____, ______, ________ to give shape to the fuselage

Answer 15

formers, frame assemblies, and bulkheads

Question 16

A heavy frame to contain pressures or
fluids or to disperse concentrated loads.

Answer 16

Bulkhead

Question 17

This construction is a modification to the monocoque type wherein the skin is stiffened by
longitudinal elements. (stiffeners, stringers, longeron).

Answer 17

Semi-monocoque Type

Question 18

The principal longitudinal member of
the fuselage that helps the skin support primary
bending load.

Answer 18

Longeron.

Question 19

Longitudinal member in the fuselage (or
spanwise member in the wing) to transmit skin
loads to body frames or wing rib.

Answer 19

Stringer.

Question 20

A metal part, other than flat sheet, used
in framing of a structure to provide rigidity

Answer 20

Stiffener.

Question 21

prevent stress concentration

Answer 21

Rounded corners

Question 22

fitted to pressurized aircraft must
withstand both the loads of pressurization and impact loads from bird strikes. They are constructed from toughened glass panels attached to each side of a clear vinyl interlayer.

Answer 22

Flight Deck Windows

Question 23

They are designed to be fail-safe and normally have two panes of acrylic plastic mounted in an airtight rubber seal fitted into a metal window frame. If one pane fails the other will prevent loss of cabin pressure

Answer 23

Passenger Cabin Windows
