2. Summary
Conclusions:
Mechanical Systems detailed design and analysis indicates that all requirements will be met.
Mechanical Systems has accommodated changes since dPDR.
Overall design is in good shape
Grid Box Assembly design is nearly complete.
Radiator and Heat Pipe designs are nearly complete.
Cal-Grid interface is still in review and has consumed 100’s of man-hours to date. This needs to be resolved immediately.
Risk list items are understood & mitigation plans are in place.
Radiator design has matured and fabrication will begin after I-CDR.
Aluminum billets for Grid are on order.
LM’s X-LAT team has come up to speed quickly and made several design improvements.
LM has team in place to execute to their plan.
Closure plan for the open issues will be in place by I-CDR.
