The airframe of a fixed-wing aircraft consists of the
following five major units: ( ada 5 bagian utama pada pesawat )
1. Fuselage
2. Wings
3. Stabilizers
4. Flight controls surfaces
5. Landing gear
A rotary-wing aircraft consists of the following
four major units: ( 4 bagian utama pada helikopter )
1. Fuselage
2. Landing gear
3. Main rotor assembly
4. Tail rotor assembly
STRUCTURAL STRESS
Five Types Of Stress: ( 5 stress yang terjadi pada kontruksi pesawat pesawat )
Tension Stress
Compression Stress
Torsion Stress
Shear Stress
Bending Stress
1. Tension is the stress that resists a force that tends to
pull apart
2. Compression is the stress that resists a crushing force. The
compression strength of a material is also measured in Psi; compression is the
stress that tends shortens aircraft
3. Torsion is the stress that produces twisting, while
aircraft moving forward the engine also
tends to twist it to one side, but other aircraft components hold it on course;
thus torsion is created. The torsion strength of a material is its resistance
to twisting or torque.
4. Shear is the stress that resists the force tending to
cause one layer of material to slide over an adjacent layer. Two riveted plates
in tension subject the rivets to a sharing force. Aircraft parts, especially
screws, bolts, and rivets are often subjected to a sharing force.
5. Bending stress is a combination of compression and tension
(compressed) on the inside on the bend and stretched on the outside of the
bend.
