Lift acts in the direction of low pressure - correct answer - How does an
airplane acheive lift?
Left wing; clockwise
Right wing; counterclockwise - correct answer - Describe the direction of
wing tip vortices.
All parts of the airplane that do not contribute to lift
Sub components:
1) form drag: drag created by the shape of body
2) skin friction: tendency of air flowing over a body to cling to its surface -
correct answer - What is parasite drag?
What are the sub components of parasite drag?
The parts of the aeroplane that are actively producing lift - correct answer -
What is induced drag?
, Page |2
The drag produced by the down going aileron. It is corrected with frise and
differential ailerons. - correct answer - What is Aileron Drag? How is it
corrected on some planes?
Boundary layer: thin sheet of air lying over the surface of the wing
1) laminar layer: it's basically the boundary layer
2) transition point: the point of transition between laminar and turbulent
3) turbulent layer: due to friction the laminar layer become turbulent -
correct answer - Explain the boundary layer, and the 3 parts that it turns
into.
Angle of the wing to the longitudinal axis - correct answer - What's the
angle of incidence?
Fin-like vertical surfaces attached to the upper surface of the wing, used to
control airflow. They prevent air to travel towards the tip of the wing during
high angles of attack. - correct answer - Explain wing fences.
They are passageways built into the wing. At high angles of attack. The air
flows through the slot and over the wing to smooth out eddies. - correct
answer - What are slots?
