Aireron Drag

Question 1

when an airplane is making a turn what happens?

Answer 1

One aileron is put down and the other one is raised up

Question 2

What does the aileron that is put down create?

Answer 2

The aileron that is put down creates drag

Question 3

What position is the upper aileron in?

Answer 3

It is in the streamline position which creates less drag

Question 4

What is the aileron in the downgoing position called?

Answer 4

The aileron drag

Question 5

What are 2 designs that overcome aileron drag?

Answer 5

1) Frise

2) Differential ailerons

Question 6

What happens in a differential ailerons?

Answer 6

The downgoing ailerons is designed at a smaller angle than the upgoing aileron. This result in the downgoing aileron to produce less drag.

Since the upgoing aileron is larger it will cause more drag but the combine effect will balance the drag out

Question 7

What happens in a Frise ailerons?

Answer 7

Downgoing aileron is designed to be streamlined into a wing which causes less drag. The upgoing aileron nose projects into the airflow which increases drag

Balances each other out
