  • 1

    Sticky or adhesive characteristic of a fluid.

    Viscosity

  • 2

    Assumed to involve no friction, thermal conduction, or diffusion

    Inviscid Flow

  • 3

    The region of viscous flow which has been retarded owing to friction at the surface

    Boundary Layer

  • 4

    Are smooth and regular and the fluid elements smoothly along the streamlines

    Laminar Flow

  • 5

    Breaks up and a fluid elements move in a random, irregular torturous fashion

    Turbulent Flow

  • 6

    Measure of ratio if inertial forces to viscous forces

    Reynold’s Number

  • 7

    Where Laminar smooth flowing turns into Turbulent flow, is where the Reynolds Number reaches critical value

    Transition Point

  • 8

    Causes shear stress at the surface

    Air Friction

  • 9

    Contributes to Aerodynamic Drag

    Skin Friction Drag

  • 10

    Pressure drag due to separation

    Flow Separation

  • 11

    A condition in aerodynamics and aviation wherein the AOA increases beyond a certain point such that lift begins to decrease

    Stall

  • 12

    this type of stall are practiced to simulate take-off and climb-out conditions and configurations

    Departure Stall

  • 13

    occurs when you pull the aircraft nose up too high while maintaining full power.

    power on stall

  • 14

    this type of stall are practiced to simulate normal approach-to-landing conditions and configurations

    Arrival Stall

  • 15

    occurs when an aircraft is in a landing configuration, usually with the landing gear down and reduced power.

    power off stall

  • 16

    More severe than un-accelerated stalls and are often unexpected

    Accelerated Stall

  • 17

    simulates a base to final skidding turn, where pilots may apply aileron in one direction rudder in the direction.

    Cross Controlled Stall

  • 18

    Air is the fluid through which airplanes move

    Drag

  • 19

    is comprised of all the forces that work to slow an aircraft’s movement.

    Parasite Drag

  • 20

    is the portion of parasite drag generated by the aircraft due to its shape and airflow around it.

    Form Drag

  • 21

    comes from the intersection of airstreams that creates eddy currents, turbulence, or restricts smooth airflow.

    Interference Drag

  • 22

     is the aerodynamic resistance due to the contact of moving air with the surface of an aircraft.

    Skin Friction Drag

  • 23

    The second basic type of drag

    Induced Drag

  • 24

    The relationship between the drag coefficient and the lift coefficient.

    Drag Polar

  • 25

    As the air and vortices roll off the back of your wing, they angle down

    Downwash
