Aircraft Axis And Wings Flashcards
Where do yaw, roll and pitch act from?
Centre of gravity.
True or false the gross wing area doesn’t include the fuselage?
False.
How do you measure the taper ratio?
Tip chord/root chord.
How do you measure the mean geometric chord?
Wing area/wing span.
The mean aerodynamic chord has similar blank blank properties to the wing.
Longitudinal stability.
Wing span ^2 / wing area is know as what?
Aspect ratio.
What type of aircraft has a high aspect ratio?
Glider.
What percentage of the chord line is the sweep angle?
25%
What does the angle of incidence measure the angle between?
Longitudinal axis and the chord.
What part of the wing does washout reduce stalling tendencies?
Wing tip.
Other than winglets, what else can reduce wingtip vortices?
Washout.
How do you measure the aspect ratio of a rectangular wing?
Span/chord.
How do you measure the aspect ratio of a swept wing?
Span^2/area
Do low or high aspect ratio aircraft have a higher coefficient of lift for a given angle of attack?
High aspect ratio.
How do you measure the thickness of a wing?
Max thickness/chord length x 100
