wing __________ was done by the brothers for the first time to control the roll of a flying machine
8.
a type of material the majority of today's aircraft are built with
9.
the type of mechanics the brothers were.
10.
_____ Lilenthal's aerodynamic data was used by the brothers
11.
a type of tunnel used to test, analyze, and improve airfoil designs
12.
a wing shape that when moved through a fluid produces an aerodynamic force.
13.
the edge of an airfoil that air makes the first contact
14.
the edge of an airfoil that air makes the last contact
15.
a straight line that connects the leading edge to the trailing edge
16.
the angle of _____ is the angle between the chord line and the relative wind flow.
17.
maximum distance between the upper and lower wing surfaces.
19.
the type of airfoil where the upper and lower surfaces are identical
20.
the type of airfoil where the upper surface is more curved.
21.
the shape of the airfoil when viewing from above
22.
the length from the trailing edge to the leading edge
23.
the length between the ends of the wingtips
24.
is directly affected by the angle of attack
25.
is when the critical angle of attack is reached and caused the boundary layer of air to separate from the airfoil and creates drag
