No. Barrel rolls do NOT go negative generally. If you went negative
you would change the roll arc and destroy the roll. You can unload
to 0 g through the top however without destroying the roll arc, but
if you do, you have to reapply positive g almost immediately as you
pass through inverted to regain the roll arc. As I said, you can
do a barrel roll at any positive g; as tight or as little as the
flight envelope for the aircraft will allow up to 90 degrees of
flight path direction change at the roll apex.
Generally the roll profile will be the application of positive g
above +1
from the roll initiation (either from level flight or from a slight
dive offset to gain energy if needed) followed by coordinated roll
and back pressure into the roll arc maintaining positive g with
varying back pressure to maintain the roll arc through the roll and
through the recovery back to the entry heading.
You can NOT at any time during a barrel roll, allow the g to go
negative as doing so will instantly destroy the arc of the roll.

No it won't, and yes you can.

I'm sorry, but you are totally incorrect.
Dudley Henriques


Certainly not. If you think you cannot roll the wings of an aircraft,
and remain in total control of the g loading, you are totally
incorrect.

If you want to argue the proper name for this manuver is not a barrel
roll, that's another topic, and I would agree. Many people incorrectly
refer to all rolls as barrel rolls. But then we would just be nit
picking, wouldn't we.


Dudley's right, you're wrong,. You're twisting the argument to suit
yourself, changeing the language and rules as you go...
