For 10 points, In Aerodynamics, are ailerons used to move aircrafts side to side or up and down?

Answer 1

Ailerons are hinged control surfaces attached to the trailing edge of the wing of a fixed-wing aircraft. They are used to control the aircraft in roll. The two ailerons are interconnected so that one goes down when the other goes up: the downgoing aileron increases the lift on its wing while the upgoing aileron reduces the lift on the other wing, producing a rolling moment about the aircraft's longitudinal axis. The word aileron is French for "little wing."


Ailerons are mounted on the back edge of each wing near the wingtips, and move in opposite directions. When the pilot moves the stick left, or turns the wheel counter-clockwise, the left aileron goes up and the right aileron goes down. A raised aileron reduces lift on that wing and a lowered one increases lift, so moving the stick left causes the left wing to drop and the right wing to rise. This causes the plane to bank left and begin to turn to the left. Centering the stick returns the ailerons to neutral maintaining the bank angle. The plane will continue to turn until opposite aileron motion returns the bank angle to zero to fly straight.

Another control surface that combines an aileron and flap is called a flaperon. A single surface on each wing serves both purposes: used as an aileron, the flaperons left and right are actuated differentially; when used as a flap, both flaperons are actuated downwards. As an example of an aircraft using flaperons, see this RJ.03 IBIS experimental aircraft. Please note that when a flaperon is actuated downwards (i.e. used as a flap) there is enough freedom of movement left to be able to still use the aileron function.

In short, both!

Answer 2

There are 3 axis that aircraft move on Yaw which is right and left, Roll, which spins the aircraft and Pitch, which is up and down. Ailerons produce Roll. Elevators produce pitch and a rudder produces the Yaw. This is on a normal aircraft. There are such things as flaperons which were used on earlier model B52 aircraft that did the job of both the flap and the aileron. But normally what you are talking about is the Roll aspect being an aileron.

Answer 3

Ailerons affect the roll axis. Elevators affect the pitch axis. The rudder affects the yaw axis.

So really, the ailerons cause the plane to roll, and the new direction of lift causes the plane to turn in the direction of the lower wing. It doesn't really move "side to side" per se.

Answer 4

it won't lean. it is going to roll. the ailerons in user-friendly terms roll the plane. yet use ailerons and rudder you will lean and change. If the aileron is going up it is going to push that wing down. And the different will bypass down and THE WING WILL bypass UP ON THAT section. like it you place your hand out the window of your automobile advance the front of the hand the wind pushes your hand up. this is the comparable with all flight controls on a plane. have been the flight administration is dictates what the plane will do.

Answer 5

Neither. They are used to ROLL the aircraft through the Z-axis

Answer 6

the ailerons are for LIFT and roll of a plane...

Answer 7

They are flaps that move up and down to stabilize an aircraft, smartass...

Answer 8

Both

Answer 9

Side to side, up and down and I love you!

Answer 10
