,How many units does the airframe consist of? Five
What are the five principle units the airframe consist of? The fuselage, Wings, Stabilizers, Flight Control Surfaces and landing gear
What do helicopter Airframes consist of? Helicopter airframes consist of the fuselage, main rotor, and related gearbox, tail
rotor, and the landing gear.
Modern Airframe structures are commonly made of? Aluminum
Many newly certificated aircraft are built from? Molded composite materials, such as carbon fiber
Structural members of an aircraft fuselage include? stringers, longerons, ribs, bulkheads, and more
The main structural member in a wing is called? The wing Spar
skin of aircraft can be made from a variety of materials Impregnated Fabric, plywood, aluminum or composites
ranging from?
The entire airframe and its components are joined by? rivets, bolts, screws, and other fasteners
-Welding, adhesives, and special bonding are also used.
Aircraft structural members are designed to? Carry a load or to resist stress
Every part of the aircraft must be? Planned to carry the load to be imposed on it.
In most cases structural members are designed to? Carry end loads rather than side loads
"to carry end loads rather than side loads" mostly when a structural member is subjected to tension or compression rather than
means? bending.
Define Stress Analysis the determination of the loads to be carried by structural members
The technician must understand the stresses involved in Avoid avoid changes in the original design through improper repairs
structural members to?
Are stress and strain the same thing? They are not the same thing
, What causes stress? External loads or forces
Define stress internal resistance or counterforce, that opposes deformation
Define Strain The degree of deformation of a material
When a material is subjected to a load or force, the Deformed - regardless of how strong the material is or how light the load is
material is?
How many major stress are aircraft subjected to? 5
What are the five major stresses aircraft are subjected Tension, Compression, Torsion, Shear, Bending.
to?
Define Tension the stress that resist a force that tends to pull something apart
Tensile strength of a material is measured in? Pounds per square inch (psi) and its calculated by dividing the load (in pounds)
required to pull the material apart by its cross-sectional area (in square inches)
Define compression The stress that resists a crushing force
The comprehensive strength of a material is measured PSI
in?
Compression is the stress that tends to? Shorten or Squeeze Aircraft parts
Define Torsion the Stress that produces twisting
The torsion strength of a material is? its resistance to twisting or torque
Define Shear The stress that resists the force tending to cause one layer of a material to slide
over an adjacent layer
Two riveted plates in tension subject rivets to? A shearing force
Usually the shearing strength of a material is? Either equal to or less than its tensile or compressive strength
