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.
