Class,
For this week’s module discussion post, I am choosing to write about the
topic of pressure, which can be found in chapter 4.2 of
Inquiry Into
Physics
. According to our textbook, pressure is defined as the quantity of
force per unit area when the force acts perpendicular to the surface
(Ostdiek & Bord, 2018). Common units of measuring pressure are pounds
per square inch (PSI) in the English system, Pascals (Pa) is the SI unit, and
Bar (Bar) is the metric unit which is about equal to the atmospheric
pressure at sea level on Earth.
Pressure has a significant impact on many aspects of aviation and is
present in different forms from solids, liquids, and gasses. The air or
nitrogen found in tires is pressurized, fuel pumps create high pressurized
fuel to atomize in the combustion chamber, and hydraulic pressure is
needed to overcome the pressure on the primary flight control surfaces.
According to Bernoulli’s Principle, we could not achieve flight without the
differential of pressure between the upper and lower cross-section of an
airfoil (Ostdiek & Bord, 2018).

The aerospace industry is constantly being challenged to create aircraft
that are lighter, faster, stronger, and more fuel-efficient. Engineers have
been creating advanced complex composite parts that require
manufacturers to use an autoclave. The autoclave process is a unique
process because it uses vacuum and pressure on composite resin parts to
create lighter and stronger components. The autoclave processes of
making a composite component consist of layering composite-resin
materials on a mold, then putting that mold in a vacuum bag that is
placed inside a pressure vessel. The bag gets pulled to a vacuum of zero
atmospheres, while at the same time the pressure vessel is pressurized to
nearly six to eight atmospheres to the outside of the bag (Dyer, 2017).
This differential pressure process allows even pressure forces to be

distributed over the molded part being manufactured. Without this
process, we would not have the complex carbon fiber parts found in
aviation today.
