Lift Flashcards
Aero
Pertaining to air.
Aerodynamics
Relating to the forces of air in motion.
Aeronautics
The science of flight within the atmosphere.
Aerospace
A combination of aeronautics and space.
Air
A mixture of gases that contains approximately 78% nitrogen, 21% oxygen, and 1% other gases.
Aircraft
Any machine that is capable of flying through the air; included are ultralights, airplanes, gliders, balloons, helicopters, hang gliders, and parasails.
Airplane
An aircraft that is kept aloft by the aerodynamic forces on its wings and thrust forward by a means of propulsion.
Airfoil
A component, such as a wing, that is specifically designed to produce lift, thrust, or directional stability.
Airport
A place on either land or water where aircraft can land and take off for flight.
Altitude
Height above sea level or ground level, expressed in units.
Aviation
The art, science, and technology of flight within the atmosphere.
Aviator
A person who operates an aircraft in flight.
Camber
The curved part of an airfoil, from its leading to trailing edge.
Chord
A line drawn through an airfoil, from its leading to trailing edge.
Downwash
The downward movement of air behind a wing in flight.
Drag
A force that slows the forward movement of an aircraft in flight.
Dynamic
Forces in motion.
Gravity
The natural force pulling everything to Earth.
Leading edge
The front part of a wing or airfoil.
Lift
The upward force that opposes gravity and supports the weight of an aircraft.
Relative wind
The flow of air that moves opposite the flight path of an airplane.
Thrust
The force that moves an aircraft forward in flight.
Upwash
The upward movement of air ahead of the wing in flight.
Vortex
A spinning column of air that is created behind the wingtip as a result of air moving from an area of high pressure on the bottom to an area of low pressure on top.
