Cooper
budged it off there . RCS , I mean the rate
command--One thing on rate command before
retrofire and just after retrofire, waiting
for retrojet , and then starting the pitch
up to go up and roll over inverted and go
to zero lift , the dual ring rate command
is just mor e than you can handle. It ' s
just a lot more than control authority than
you want--you tend to over- shoot on things
because there is just so much control
tor que in there . As I had stated, after
I f ired retro and jettisoned the retropack
and pitched up to roll over then from
ther eon I went to s i ngle ring pulse, and
used that . Reentry rate command--we didn ' t
use . Direct - used direct t o do the reentry
on single ring direct and used the pulse
mode from r etrojet to 400K.
On the single ring direct reentry did you
have--did you feel like you had all the
authority you wanted?
Yeah--until very late--as I stated some
time down , oh, half way thru the reentry
