POF - Axes And Wings Flashcards
What is the angle of incidence?
It is the angle between the chord line and the aircrafts longitudinal axis.
What aspect ratio do short stubby wings have?
They have a low aspect ratio.
What does the lateral axis control on a plane?
The ability for the plane to pitch.
What is a geometric twist?
Reduction of angle of incidence from wing root to the wing tip.
What is the wing span?
The distance between between both wing tips.
What is a dihedral angle?
When the straight line is below the wing.
What does the vertical axis control on the plane?
The ability for the plane to yaw.
What is the formula for Aspect Ratio?
Wing Span^2 / Wing Area
What is the definition of the mean aerodynamic chord?
It is the chord of an imaginary rectangular wing with similar properties to the actual wing.
What does the longitudinal axis control on a plane?
It controls the ability for the plane to roll.
What is an aerodynamic twist?
It is the reduction of the wing camber from the wing root to wing tip.
What is the sweep angle?
It is a line that goes from the root to the tip.
What is an anhedral angle?
When the straight line is above the wing.
What type of aspect ratio do long thin wings have?
They have a high aspect ratio.
What are the 1st, 2nd and 3rd flow dimensions?
1st = horizontal/parallel
2nd = vertical
3rd = lateral
What is the Mean Geometric Chord formula?
Wing Area / Wing Span
What is the Taper Ratio formula?
Tip Chord / Root Chord
What are some advantages to a washout?
- reduces the tendency of wing tip stall.
- creates a more stable stall characteristic.
- reduces wing tip vortices.
What is the gross wing area?
The area of the wings including the area of the fuselage.
