WEEKLY HIGHLIGHTS FOR WEEK ENDING 24 October 1997:
STANFORD HIGHLIGHT
Ted Acworth and Rob Bernier have successfully integrated
the Artificial Star
#3 (AS3) into the GTU-2 test system.
Preliminary checks confirm the
functionality of AS3.
Optional GTU-2 tests, involving AS3 and telescope #1
are
currently in progress.
SPACE VEHICLE HIGHLIGHT
Bellelville washer stacks called out in the Belleville
Preload System
(BPS) dewar "use-as-is" concept mechanism
were stiffness (load versus
deflection) tested over their
expected operating displacements during
the week of 17
October. The BPS mechanism, an addition to the Probe
assembly, allows installation and preload of the Probe
against the Dewar
without actuation of the failed axial
lock parts. The test results were
excellent. The stack
stiffnesses were as predicted, linear and
repeatable.
Friction hysteresis was very low. Detail design of
the
mechanism machined parts is underway, and parts
for the engineering test
bed are being machined.
