BASICS OF FLIGHT AND AERODYNAMICS

ESSENTIAL QUESTIONS

• What gets a plane off the ground?

• What basic forces are working on the airplane during flight?

• What are the parts of an airplane and what do they do?

• What does “aerodynamic” mean?

• Bernoulli's Principle- the faster a fluid is moving the lower the pressure

Daniel Bernoulli

BASIC FORCES IN FLIGHT• Four Fundamentals of Flight

– Lift

– Thrust

– Weight/Gravity

– DragPg. 25

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 opposing lift

• 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 opposite to thrust

• Caused by the disruption of airflow by the plane itself and its parts (wings, landing gear, etc.)

• Two types: parasite (the most common) and induced

• Effects how aerodynamic the plane

is

ANGLE OF ATTACK

angle between the wing chord and the relative wind

THE WING

• Produces the lift

• Holds the plane up while in flight

• Bernoulli's Principle- the faster a fluid is moving the lower the pressure
