  1. FLIGHT VOCABULARY

  2. Fluid having particles that easily move and change their relative position without a separation of the mass and that easily yield to pressure : capable of flowing

  3. Air the mixture of invisible odorless tasteless gases (as nitrogen and oxygen) that surrounds the earth

  4. Pressure Definition : the burden of physical or mental distress

  5. Density the quality or state of being dense

  6. Buoyancy Definition: the tendency of a body to float or to rise when submerged in a fluid

  7. the gravitational attraction of the mass of the earth, the moon, or a planet for bodies Gravity

  8. LIFT to raise from a lower to a higher position :elevate

  9. Thrust to push or drive with force

  10. Drag Something used to drag with especially a device for dragging under water to detect or obtain objects (blue)

  11. Bernoulli’s Principle a principle in hydrodynamics: the pressure in a stream of fluid is reduced as the speed of the flow is increased

  12. Aerodynamic a branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids

  13. Aileron a movable airfoil at the trailing edge of an airplane wing that is used for imparting a rolling motion especially in banking for turns Aileron is number 17

  14. Rudder a movable auxiliary airfoil on an airplane usually attached at the rear end that serves to control direction of flight in the horizontal plane

  15. Elevators one that raises or lifts something up

  16. Fuselage the central body portion of an aircraft designed to accommodate the crew and the passengers or cargo

  17. Wings one of the movable feathered or membranous paired appendages by means of which a bird, bat, or insect is able to fly also

  18. Roll a written document that may be rolled up : scroll; specifically: a document containing an official or formal record <the rolls of parliament> (2): a manuscript book

  19. Pitch slope; also: degree of slope

  20. Yaw the action of yawing; especially: a side to side movement

  21. Aircraft a vehicle (as an airplane or balloon) for traveling through the air

  22. Spacecraft a vehicle or device designed for travel or operation outside the earth's atmosphere

  23. How Things fly

  24. How does a propeller work A propeller is like a spinning wing. Instead of pushing air behind a plane, the airfoil shaped blades pull an airplane forward

  25. How does a plane fly Four forces push and pull an airplane in flight. The wings act as an airfoil and produce an upward force called lift.

  26. How does a bird fly through the air? When a bird flaps its wings, air is pushed downward. This produces an opposite force that “lifts” the bird into the air. Since a bird’s wing is in the shape of an airfoil, it produces some lift even when the bird is just gliding.

  27. How does a helicopter fly? A helicopter can take off and land vertically (straight up and down). It can fly in any direction, even sideways and backwards. It can also hover or hang in the air above a given place.

  28. How do hot air balloons fly? In a hot air balloon, a gas burner is used to heat air to a temperature of about 212°F (100°C).

  29. How does a glider fly? The shape of a glider wing is an airfoil. This gives the wing lift. But a glider will fall to earth unless the pilot finds thermals to keep the glider up.

  30. What keeps a satellite in orbit? Once a satellite is launched into orbit, the force of gravity tends to pull it toward the Earth. But by moving fast enough, it falls in a curved path and circles the Earth.

  31. What keeps a kite in the air A kite uses the power of the wind to keep it up. The wind goes against the pull of the string and supports the kite in the air. An

  32. How does a dragonfly fly? Dragonflies are marvels of flight engineering. They can fly forward at speeds of 35 miles per hour or more.

  33. What is an airfoil? An airplane wing has a special shape called an airfoil. that help it fly

  34. How does a jet engine work? A jet engine uses a gas turbine to drive a fan that sucks in air, mixes it with burning fuel, and then blasts the expanded air-gas mixture out the back.
