Flight And Space
vocabulary
| Term | Definition |
|---|---|
| Acceleration - | The rate of change of velocity with respect to time |
| Aileron | The controlling surface that regulates an aircraft's roll |
| Airfoil | A part or surface, such as a wing, propeller blade, or rudder, whose shape and orientation control stability, direction, lift, thrust, or propulsion. |
| Camber | A measure of the curvature of the airfoil |
| cardinal directions | The four main directions: north, south, east, and west. |
| compass rose | A symbol on a map that shows orientation relative to north, south, east, and west. |
| Drag | Resistance of the air against the forward movement of an airplane |
| Elevator | The controlling surface that regulates an aircraft's pitch |
| Empennage | The tail assembly of an aircraft |
| Fluid | A gas or liquid that tends to take the shape of its container |
| Force | Transferring of energy to an object, typically by pushing or pulling on that object |
| Fuselage | The central body of an aircraft where wings and stabilizers are attached |
| Gravity | The force that attracts a body toward the center of the earth or any other physical body having mass |
| Knot | Equal to one nautical mile per hour. |
| Lift | The force that directly opposes the weight of an airplane and holds the airplane in the air |
| Mass | the amount of matter in an object |
| nautical mile | Distance measurement used in both air and marine navigation. It is equal to one minute of latitude or 1.15 miles. |
| Newton’s 1st law | Objects at rest stay at rest and objects in motion stay in motion unless an external force is applied |
| Newton's 2nd Law | The relationship among an object's mass, acceleration, and an applied force, is Force equals mass times acceleration (F=ma). |
| Newton’s 3rd law | For every action there is an equal and opposite reaction Pitch |
| Propeller | An airfoil mounted on a revolving shaft. It creates low pressure in front of it, thereby moving an aircraft forward because of the high pressure area behind it |
| Propulsion | The means by which aircraft and spacecraft are moved forward. It is a combination of factors such as thrust, lift, drag and weight |
| Roll | The clockwise or counterclockwise rotating motion of an aircraft Rudder |
| Topography | The shape and features of land surfaces, including both natural and artificial physical features of an area. |
| Thrust | A force applied to a body to propel it in a desired direction. This force moves an aircraft through the air |
| Weight | The force generated by the gravitational attraction of the earth on the airplane Lift must be equal to this force in order to sustain flight |
| Wing | The major horizontal surface on an airplane that provides lift Yaw |
