(28 cards)
What is Chord line?
Straight line connecting the leading edge and the trailing edge
What is Chord?
The length of the chord line
What is Mean Camber?
Line drawn equal distance between the upper surface and the lower surface
What is Maximum camber?
Max distance between mean camber line and chord line
What is Maximum thickness?
Maximum distance between the upper and lower surfaces
What is Leading edge radius?
Measure of the sharpness of the leading edge
What are the 2 terminology that is important to determining Aerodynamics?
- Max Camber
- Max Thickness
Characteristic of Symmetrical Airfoil?
Mean camber line and chord line are the same line
What kind of Airfoil won’t generate lift if AoA isn’t open?
Symmetrical Airfoil
Speed/Direction that air passes through the body is called?
Flight Path Velocity
Speed/Direction that is equal but opposite in direction to Flight Path Velocity is called?
Relative Wind
What is the angle of AoA from?
Between relative wind and chord line
Net resulting in static pressure is called?
Aerodynamic Force
What does Lift act perpendicular to?
Relative Wind
What does Relative Wind act parallel to?
Drag
Where does aerodynamic force act on?
Center of Pressure
Which type of airflow results in slower separation?
Turbulence Flow (High Energy)
What is the point that 3 axes intersect called?
Center of gravity

Rudder
What controls Roll?
Aileron
The Axis that is parallel to the wing is called?
Lateral Axis (Pitch)
The Axis that is parallel to the body is called?
Longitudinal Axis (Roll)
The Axis that is pointing at the sky is called?
Vertical Axis (Yaw)
