[NSRCA-discussion] Aileron Differential

[chris moon]

Is this similar to traveling at the speed of light then turning on your
headlights??

    Is there a Doppler effect if the ear listening is moving at the  
same direction and speed as the source of the sound?  <g>

      Yeah, that and the Doppler Effect.

        The Coriolis Effect . . . .

Some of you guys covered the following in various ways.

There is drag due to lift because the lift vector ( force ) is not
perpendicular to the flight direction. Drag is a function of lift
and that component of the lift vector in the flight direction is
called induced drag.

Up, and down, both ailerons produce drag, but in unequal amounts if
the wing is in lift mode. The difference in drag for pattern
airplanes is small because of low wingloading ( low AOA ).

The symmetrical airfoil plays a role in keeping the drag
differential low because, to generate equal lift , upright to
inverted, requires a different AOA for the non-symmetrical section.

What did I forget?        Nat
