26
Q

What Drag formula is this: Dp
=s
2

A

Parasite Drag

27
Q

Happens where the aircraft surfaces meet each other

A

Interference Drag

28
Q

The ___ controls the aircraft on its vertical axis.

A

Rudder

29
Q

In most general aviation airplanes, or reciprocating engines generate thrust the?

A

Propeller

30
Q

Any drag that is not associated with the production of lift

A

Parasite Drag

31
Q

As the propeller or jet engine rotates, its blades
accelerate the surrounding air towards the aft (to the back) of the aircraft.

A

Thrust

32
Q

Is caused by the roughness of the airplane’s
surface.

A

Skin-Friction Drag

33
Q

The path of least resistance is towards the wingtips, which results in the air at the bottom to move outward away from the fuselage towards the wing tips.

A

Wingtip Vortices

34
Q

Primary Flight Controls:

A

Elevator, Rudder, Ailerons

35
Q

twisting the wing to change the angle of incidence at the wing root from the angle of incidence at the wing tip

A

Wing Washout

36
Q

Stronger/higher at slower speeds.

A

Induced Drag

37
Q

The air at top of has a tendency to flow inwards,
towards the fuselage

A

Wingtip Vortices

38
Q

Axis of Pitch (?)

A

Lateral

39
Q

Parasite Drag + Induced Drag=

A

Total Drag

40
Q

They are used in combination with the ailerons to turn an airplane correctly.

A

Rudder

41
Q

Circular patters of rotating air as wing generates
lift.

A

Wingtip Vortices

42
Q

Axis of Roll (?)

A

Longitudinal

43
Q

Secondary Flight Controls

A

Wing Flaps, Trim Tabs

44
Q

Methods to Reduce Induced Drag:

A

-Tapering the Wing Planform
-Wing Tip Modification
-Wing Washout

45
Q

High Pressure goes to Low Pressure.

A

Wingtip Vortices

46
Q

Axis of Yaw (?)

A

Vertical

47
Q

These are attached to rear end, or what we call
trailing edge, of the wing.

A

Ailerons

48
Q

The ___ control the aircraft on its longitudinal axis.

A

Ailerons

49
Q

Lateral Axis (?)

A

Elevator pitch

50
Q

Elevator movement=

A

Pitch Movement

51
Q

It is used to move the aircraft up or down, and allows the aircraft to climb, descend, or maintain its desired altitude.

A

Elevator

52
Q

They move in opposite directions to create aerodynamic forces that cause the airplane to turn.

A

Ailerons

53
Q

Vertical Axis (?)

A

Rudder Yaw

54
Q

The ____ control the aircraft on its lateral axis.

A

Elevator

55
Q

Longitudinal Axis (?)

A

Aileron Roll

56
Q

is attached to the horizontal stabilizer which is located on the empennage of the aircraft.

A

Elevator

57
Q

They extend from the midpoint of each wing to the outward tip.

A

Ailerons

58
Q

The ____ is another flight control that is
located on the empennage, but this time, it is
connected on the vertical stabilizer.

A

Rudder

59
Q

Aileron movement=

A

Roll movement

60
Q

They are used to move the nose of the aircraft
left or right.

A

Rudder
