SLIDE’S MAIN CONTENTS • What does aerodynamic mean and where it is used?
• What gets a plane off the ground?
• What basic forces are working on the airplane during theflight?
• What are the parts of an airplane and what do they do?

INTRO TO THE BERNOULLI’S PRINCIPLERELATION WITH THE AERODYNAMICS
“the faster a fluid is moving the lowerthe pressure”

BASIC FORCES IN FLIGHT
• Four Fundamentals of Flight
– Lift
– Thrust
– Weight/Gravity
– Drag

LIFT
• Opposes the downward force of weight
• Produced by the dynamic effect of the air acting on
the wing
• Shape of airfoil changes the way lift acts on the
airplane
• Bernoulli’s Principle

WEIGHT/GRAVITY
• The downward force due to the weight of the airplane.
• The combined load of the airplane itself (crew, fuel,
cargo/baggage)
• Force exists because of the presence of gravity

THRUST
• Forward force produced by the propeller
• Pulls the airplane through the air
•
Opposes drag

DRAG
• Backward force acting on airplane opposite to the
thrust and the direction of the airplane.
• Caused by the disruption of airflow by the plane
itself.
• Two types: parasite and induced drag.

ANGLE OF ATTACK
Angle between the
wing chord andthe relative wind.

THE WING
• Produces the lift
• Holds the plane up and makes it
stable while in flight• In order to make Bernoulli's Principle more effective, more
surface area is introduced in form of wings.
