Since the accident aircraft was keeping up, and was on the outside of
the turn, the correct answer is more than five. That's simple
physics.

If you're saying that the aircraft "keeping up" on the outside of the
turn was at a higher g than the 5g's being pulled by the aircraft in
front and inside of him , you are mistaken.
Actually if the trailing aircraft was "keeping up" he would be at co
speed in the turn, and at co speed, the g would be the same on both
aircraft and the trailer would be the defender after 180 degrees of this
somewhat bad situation for the guy in back. This is why the attacking
aircraft can't be at the same g as the bandit and be "keeping up". The
trailer MUST have closure rate and a Ps advantage on the defender to
acheive an attack curve. This can be in a pursuit curve, usually a lag
curve at lower g with a higher attack velocity, or it can be obtained by
the use of cutoff or arcing inside the plane of turn of the defender. In
other words, the guy behind can't "keep up" by having a higher g. He
can't even keep up pulling the same g as the defender since this puts
them both in the same turn radius. The attacker must maintain a higher
attack velocity than the defender which means that in order to effect
closure and reduce angle off, he has to pull a lower g than the
defender.
Assuming both aircraft have the same Vc (corner velocity) which they do
as T34's , the only possible situation that would put the trailer at a
higher g then the defender as you have stated , would be if he was
pulling lead which would put him in a lead pursuit curve and inside the
plane of turn of the defender at a higher g....therefore no longer
"keeping up" so to speak.
Also, the attacker HAS to have a higher airspeed in the attack curve to
acheive nose/tail separation and angle off, which means, if he doesn't
pull higher g than the defender, HE MUST OVERSHOOT if he's in the plane
of turn of the defender. So if he's back there at all, he ain't at co
speed at the same g, and he has to be pulling a LOWER g, not a higher g
than the aircraft with which he's engaged.


Keep dancing.

Why so nasty to this poster? He's only asking a question. Hell, if
you're going to be nasty, at least give him the right answer :-)
