<DIV><FONT face=Arial size=2>Well, while I agree it's not worth worrying about.
I do believe that it wouldn't matter what orientation you mounted a single
cylinder engine, there would be some manuevers affected. But, axial rolls in
particular wouldn't matter.. Side, inverted, upright, from a mass distribution
standpoint, the plane couldn't tell. It would only be some wierd progression
type manuever (tumbles, etc).</FONT></DIV>

<DIV><FONT face=Arial size=2>The forces causing a non-axial roll occur only
during the acceleration phases of the roll ( starting and stopping ).
Undesireable forces are generated because masses at different distances from
the roll axis experience different rates of acceleration. In practice I don't
think we have a problem with the side-mounted engine. Would someone tell me
where to find the Mars pictures.

just point of view. In knife edge an inverted engine is now side

<DIV><FONT face=Arial size=2>Looking at
the undesirable forces that would be generated by the
assymetric distribution of weight to achieve lateral balance - hard
yaw or tight corners would produce no effect because all components
would be subject to the same acceleration. There would be an effect
during roll, however, because the masses are subjected to different
rates of acceleration (polar ) . Our planes damp and reach steady
state roll rapidly . These unwanted roll forces would cause a change
in pitch ( same as when one aileron has more throw ) during their
short life . The magnitude of the pitch change would be hard to
quantify ( by me )
