basics of flight and aerodynamics (groups b/d)
DESCRIPTION
In this presentation, you will learn how the airfoil works and how it produces lift. Also, you will learn what four basic foces of flight are acting upon the plane during flight and how they affect the way the plane flies.TRANSCRIPT

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
