Forces and Aerodynamics of Flight

Match the following

• Rudder

• The angle between the relative wind and the wing chord.

• Angle of Attack

• The air moving across the airfoil which makes lift possible

• Flaps

• The angle at which an aircraft stalls

• Relative Wind

• Allows the airfoil to generate more lift at slower speeds and increases drag.

• Critical Angle of Attack

• Turns the nose of the aircraft on the yaw access.

Match the following

• Thrust

• The force that propels the aircraft forward

• Weight

• The force that opposes the forward motion of the aircraft

• Lift

• The upward force that allows an aircraft to rise

• Drag

• The downward force on the aircraft caused by gravity

Match the following

• Lift

• Every action has an equal and opposite reaction

• Daniel Bernoulli

• The propulsive force of a jet or rocket engine

• Knight

• Windsor Forest Mascot

• Newton's Third Law

• Faster moving fluid as lower pressure

• Thrust

• • An upward force that raises an object, opposing its weight

When are the four forces of flight in equilibrium?

• Lift=Weight

  Thrust=Drag

• Never

• While Climbing

The angle of attack is the angle between the relative wind and the wing's _____?

• camber

• chord

Match the following:

• Drag Force

• Created by engines or propellers

• Weight Force

• Air resistance opposing motion

Match the axis of flight to its direction.

• Runs from nose to tail of the aircraft

• Lateral

• Runs top to bottom through the aircraft

• Longitudinal

• Runs from wingtip to wingtip
