He made wings out of feathers and wax, but flew too close to the sun and died when the wax melted.
Who is Icarus?
100
The two phases of bird flight.
What are the ground phase and lift phase?
100
The front part of the wing that meets the relative wind.
What is the leading edge?
100
The four forces acting upon an aircraft.
What are lift, weight, thrust, and drag?
100
The three axes on a plane.
What are vertical, longitudinal, and lateral axes?
200
Marco Polo saw these attached to kites being used as military observers.
Who were Chinese sailors?
200
Two great scientists the unlocked the secrets of flight.
Who are Daniel Bernoulli and Sir Isaac Newton?
200
The back part of an airfoil.
What is the trailing edge?
200
The angle between the chord line and the relative wind.
What is the angle of attack?
200
Where all three axes meet on an aircraft.
What is the center of gravity?
300
The first true powered flight with humans aboard.
What is in a hot air balloon?
300
When a fluid (like air) is accelerated, the pressure drops.
What is Bernoulli's principle?
300
The imaginary line running from the leading edge to the trailing edge.
What is the chord?
300
The point at which a wing will stall.
What is the critical angle of attack?
300
The motion caused by the elevators around the lateral axis.
What is pitch?
400
They created a manned hot air balloon.
Who are Joseph and Etienne Montgolfier?
400
He wrote three laws that affect a plane in every stage of flight.
Who is Sir Isaac Newton?
400
The two sections of the wing that are above and below the chord.
What are the upper and lower cambers?
400
This is an artificial force because it requires a mechanical device to create the pressure changes.
What is lift?
400
The motion caused by the rudder that moves the plane around the vertical axis?
What is yaw?
500
They made a historic 25 minute flight over Paris on November 21, 1783.
Who are Pilatre d'Rozier and Francois d'Arlandes?
500
This law of Newton's deals with a plane sitting on a runway.
What is an object at rest will remain at rest unless acted upon by some outside force?
500
The flow of air that moves opposite the flight path of an airplane.
What is the relative wind?
500
Increase the wing's surface area, increase the wing's upper curvature, and increase speed.
What are the ways to increase lift?
500
Causes the rolling motion around the longitudinal axis.
What are the ailerons?
