SDL
Coordinate with SDL before burning flight level part on
EM2 – hold off until at least mid-April.
BB-CDR-2
UW
SDL
Change terminology for “spare 1, 2, 3” Blackbody
Controller Data Channels to say “configurable 1, 2, 3”
BB-CDR-3
SDL
UW
Resolve low temp acceptance testing for BBC using SDL
Bus Simulator.
BB-CDR-4
UW (Doug
Adler)
SDL
Share mechanical drawings and information on
properties of Noryl.
BB-CDR-5
UW
SDL
Check impact of a 2-3 K increase in temperature (above
the nominal 220 K) of the blackbody mounting platform.
BB-CDR-6
UW
SDL
Consider 1350 Aluminum (over 6061 Aluminum) to
improve conductivity in thermal cavity.
BB-CDR-7
UW (Doug
Adler)
SDL
Consider conducting thermal sensitivity analysis to
further define design margin.
BB-CDR-8
UW
SDL
Add dates and review with respective parties the
Assembly, Integration, Test Flow diagram.
BB-CDR-9
UW
SDL
Add EM2 Board delivery date to schedule for EMI tests.
BB-CDR-10
SDL
UW
Discuss board fabrication vendor options.
BB-CDR-11
SDL
UW
Discuss plans for thermal vacuum testing.
BB-CDR-12
SDL
UW
Work on Product Assurance Implementation Plan.
BB-CDR-13
SDL
UW
Check if it is appropriate to identify a Payload Hazard in
the “Temperature” category related to an overheat
condition in the blackbody that could lead to paint
contamination on-orbit. The mitigation plan can be the
existing over-temperature feature of the blackbody
controller design.
BB-CDR-14
UW
SDL
Add Temperature Hazard defined in BB-CDR-13, if it is
deemed appropriate.
BB-CDR-15
SDL
UW
Talk to colleagues about non-contacting tools to measure
paint thickness.
