Not to offend anyone, but Mr. Doug Houk is incorrect when he states
"Actually they (airplanes) do turn because of the rudder, why do you
think its (sic) there?"
Jack Northrop plus the guys'n girls that designed the current stealth
bomber would take you to task. *Conventional* airplanes turn the same
way flying wings turn. Aerodynamics 101. One wing is reconfigured to
have more lift than the other This is accomplished by changing the shape
of the wings via the ailerons. The rudder (which is just a movable portion of
the vertical stabilizer) keeps the airplane from "skidding", or, helps the
airplane TO "skid", ie: desired *crabbing* in a cross-wind, etc. If you
relied on only rudder input to turn, you'd pretty much just skid sideways
(yaw) without doing a lot of turning. You'd also lose a lot of lift and
which is a no-no. The rudder is commonly used in conjunction with the
ailerons because lift (and therefore drag) is increased on the same wing and
and the airplane will want to to be "pushed" in that direction. This is
compensated to the desired degree by the good ol' rudder pedal.
As for "dialing in the rudder" for engines out on one side, you better
work at changing the wings and messing with the remaining throttles
while you are "dialing".
