Airplanes - Subcomponents
|
| |
The subcomponents
of an airplane include the airframe, electrical
system, flight controls, and brakes.
|
| |
Airframe
|
| |
|
The airframe
is the basic structure of an aircraft and is
designed to withstand all aerodynamic forces,
as well as the stresses imposed by the weight
of the fuel, crew, and payload.

Electrical
system
|
| |
|
The primary function
of an aircraft electrical system is to generate,
regulate, and distribute electrical power throughout
the aircraft. There are several different power
sources on aircraft to power the aircraft electrical
systems.
In our C172s, we have an alternator.

Flight Controls
|
| |
|
The flight controls
are the devices and systems that govern the
attitude of an aircraft and, as a result, the
flight path followed by the aircraft. In the
case of many conventional airplanes, the primary
flight controls utilize hinged, trailing-edge
surfaces called
- elevators for pitch
- ailerons for roll
- and the rudder for yaw

Brakes
|
| |
|
In the case of
most modern airplanes, airplane brakes consist
of multiple pads (called caliper pads) that
are hydraulically squeezed toward each other
with a rotating disk (called a rotor) between
them. The pads place pressure on the rotor which
is turning with the wheels. As a result of the
increased friction on the rotor, the wheels
inherently slow down and stop turning.
