Laminar Flow
The flow of a fluid in a parallel layers in which each layer or streamline, has a unique velocity
but there can be relative motion between
Turbulent Flow
The flow of fluid in which the velocity in the flow is nonuniform and variable at any point.
Vortex (vortices)
A swirling or circular motion in a fluid or gas
Upwash
The zone in front of a wing in which the airflow just in front of the approaching airfoil is
deflected upward
Momentum
The quantity that describes the total motion of an object; the product of the objects mass and
velocity
Deflection
The angle at which the control surface is displaced from a neutral position
Energy
The total change that occurs, or can occur, in a system.
Downwash
The downward flow of air that is leaving the trailing edge of a wing as it moves through the air
Coefficient
A term in a mathematical equation used to scale numerical answer to the correct size.
Center of Pressure
Pressure varies from location to location on the wing or rotor of an aircraft.
Asymmetrical
A shape that has different features in opposite directions in relationship to a line or a
point.
Angle of Attack
The measure in degrees between the chord line of an airfoil and the relative wind
Symmetrical
Having an iodentical but opposite shape across a line or plane of symmetry
Kinetic (energy)
The ability to cause change due to the speed of an object.
Potential (energy)
The ability to cause change due to the position of an object and it's ability to fall sometime in
the future
Ground Effect
The increased lift and reduced drag experienced by an aircraft when it's operating within one
wingspan of the ground.
