Mechanical design team is reinforced by Corrado
Gargiulo (INFN) for box design
SYSU will perform detailed analyses on box and
component (accumulator) design
Progress
Bolt sharing with a.o. main radiator bracket solved
New draft mechanical box design available detailing
on-going
Components interfaces 90% finalised (see
components)
Preliminary stress analyses (SYSU) show sufficient
margin

Actions to tackle start-up problem decided on TWG
meeting at NLR
Investigate possible super-critical pump start-up
(PDT/NLR/CAST) Start-up analyses of orbital cases (SYSU/CGS)
Start-up radiator design decisions
Investigation of severity of the problem (b-angles)
TTCS Start-up

PDT pump tests are being performed right now
Pressure head measurements
suction capability with air or vapour
Design is based on the MER-rover pump which has
been tested for 24 hour with closed valves
(circumstantial evidence)
Accumulator transition tests from super- to sub-
critical state will be implemented in EM testing toverify wetting of the wick after super-critical start-
up

Start-up radiator improves the TTCS start-up
capabilities
No freezing problem is present in the box with the
start-up radiator Always one TTCS-loop able to start-up in AMS start-
up configuration
Additional analyses required for start-up in AMS-on
configuration
Supercritical start-up is investigated. If possible it
is detrimental for pump lifetime (however a system
operational decision and option) and makes switch
between P and S at all times possible

Component Status
Pump (PDT)
Design Review at PDT
Electronically pump design is progressing well
Motor design mature (proven design) BBM curve test performed
pump can deliver more flow then required
Impeller adaptations are being implemented to have better
control Hall effect sensor issue solved (no Pressure dependence)
Super-critical start-up testing on-going
Planning EM delivery early December 2005

Condenser safety conclusion (TWG meeting at NLR)
Transport tubing have to show leak before burst
approval required from safety panel
Advantage is that the condenser manifolds can go
back to the old upper trunnion bridge locations with
shorter (lower pressure drop) condenser lines
