1. FLUID  a substance, such as a liquid or gas, that is capable of flowing and that changes its shape at a steady rate when acted upon by a force tending to change its shape.force  Aeronautical engineers study fluid dynamics.  blue directional lines represent flow of the fluid air AIR FOIL

2.  air is a fluid  a mixture of nitrogen, oxygen, and minute amounts of other gases that surrounds the earth and forms its atmospheremixture  blue lines represent the air

3.  the exertion of force upon a surface by an object, fluid, etc., in contact with it: the pressure of wind against a wall forceobject  air exerts pressure against the external surfaces of the airplane as it flows over the airplane

4.  the state or quality of being dense; compactness; closely set or crowded conditionset  example of gas molecules—....  air density influences engine performance

5.  the power to float or rise in a fluid; relative lightness-----refers to boats

7.  the force of attraction by which terrestrial bodies tend to fall toward the center of the earthforcewhich  pulls plane toward the earth  Force of lift must exceed the force of gravity

8.  lift and speed angles affect the plane  to move or bring (something) upward from the ground or other support to a higher position; hoist

9.  opposes drag  thrust must be greater than drag  a linear reactive force exerted by a propeller, propulsive gases, etc., to propel a ship, aircraft, etc.

10.  force-opposes forward motion of the aircraft  to draw with force, effort, or difficulty; pull heavily or slowly along; haul; trailforce

11.  an increase in the velocity of a fluid that is accompanied by a decrease of pressure. Swiss scientist, Daniel Bernoulli (1700-1782), demonstrated that, in most cases, the pressure in a liquid or gas decreases as the liquid or gas moves faster. This explains in part why a wing lifts an airplane.

12.  Applies to fluids

13.  Study of how air flows around the airplane  the branch of mechanics that deals with the motion of air and other gases and with the effects of such motion on bodies in the medium.

15.  a movable surface, usually near the trailing edge of a wing, that controls the roll of the airframe or effects maneuvers, as banks and the like.

16.  a movable control surface attached to a vertical stabilizer, located at the rear of an airplane and used, along with the ailerons, to turn the airplane-feet control rudder.control

17.  a hinged horizontal surface on an airplane or the like, used to control the longitudinal inclination and usually placed at the tail end of the fuselage.-trailing edge of the horizontal stabilizer.control

18.  the complete central structure to which the wing, tail surfaces, and engines are attached on an airplane. The body.which

19. Airplane wings are curved on the top which make air move faster over the top of the wing. It moves slower underneath the wing. The slow air pushes up from below while the faster air pushes down from the top. This forces the wing to lift up into the air.

21.  stick goes forward trees get bigger  stick goes back trees get smaller  horizontal Stabilizer –elevators used  http://www.grc.nasa.gov/WWW/k-12/airplane/pitch.html http://www.grc.nasa.gov/WWW/k-12/airplane/pitch.html http://www.youtube.com/watch?v=I_Hgckch- oA&feature=fvsr

22.  vertical Stabilizer— uses the rudder vertical Stabilizer— uses the rudder  movement of the nose of the aircraft from side to side movement of the nose of the aircraft from side to side  http://www.grc.nasa.gov/WWW/k-12/airplane/yaw.html http://www.grc.nasa.gov/WWW/k-12/airplane/yaw.html  http://www.youtube.com/watch?v=6Ddwm4_CaYE&feature=channel http://www.youtube.com/watch?v=6Ddwm4_CaYE&feature=channel

23.  the roll axis is perpendicular to the other two axes with its origin at the center of gravity, and is directed towards the nose of the aircraft  a rolling motion is an up and down movement of the wing tips of the aircraft-uses the ailerons  http://www.grc.nasa.gov/WWW/k-12/airplane/roll.html http://www.grc.nasa.gov/WWW/k-12/airplane/roll.html  http://www.youtube.com/watch?v=VYSXWy7nzY0&feature= channel http://www.youtube.com/watch?v=VYSXWy7nzY0&feature= channel
