

Work
Aerodynamics
 Aerodynamics
concerns the motion of air and other
gaseous fluids and other forces acting on objects in
motion through the air (gases).
 In
effect, Aerodynamics is concerned with the
object (aircraft), the movement (Relative Wind),
and the air (Atmosphere).
Newton’s Laws of Motion
 Newton's
three laws of
motion are:

Inertia - A body at rest will remain at
rest. and a body in motion will
remain in motion at the same speed
and direction until affected by some
external force.
 Nothing starts or stops without
an outside force to bring about or
prevent motion. Hence, the force
with which a body offers
resistance to change is called the
force of inertia.
Newton’s Laws of Motion
 Newton's
three laws of
motion are:

Acceleration - The force required
to produce a change in motion of
a body is directly proportional to
its mass and the rate of change in
its velocity.
 Acceleration refers either to an
increase or a decrease in
velocity, although Deceleration
is commonly used to indicate a
decrease.
Newton’s Laws of Motion
 Newton's
three laws of motion
are:

Action / Reaction - For every action
there is an equal and opposite
reaction.
 If an interaction occurs between two
bodies, equal forces in opposite
directions will be imparted to each
body.
Who is Daniel Bernoulli?
physicist –
born in 1738
 Dutch-born
 Discovered
a relationship
between the pressure and
speed of a fluid in motion
– as velocity of
a fluid increases, the
pressure decreases
 Specifically
Who is Daniel Bernoulli?
 For
Lift to occur - The
pressure on top of the
airfoil must be less than the
pressure below.
 The
airfoil has no choice
but to move upward.
Who is Daniel Bernoulli?
 Camber
determines the
amount of lift an airfoil will
produce at a given speed
 The
thicker or more
pronounced the camber –
the more lift.
 At
low speeds its best to
have a high-lift airfoil.
