Overview - FPU Technical Status
FPU Structures
• Detailed design of:
 Housing compartments and substructure



Easily accessable subunits (chopper, grating, bolometer…)
Exchange of full compartments possible
Excellent stray light suppression
 FPU suspension (iso-static mounting)
 Mirrors and mounts /procurement
 Distribution boards, cabling configuration /procurement
 Interfaces to subunits
• Detailed planning of manufacturing phase

Overview - FPU Technical Status
FPU Structures (cont.)
Points to be worked on
• Structural Analysis FPU
 Values for resonance amplification
•
FPU Mass Budget
 Weight to be reduced
• Cannon ITT Connectors
 Connectors needs to be light tight

Overview: Status FPU Interfaces
 All FPU interfaces are defined
 Detailed interface requirements are worked out and
documented in the Subunit Specifications
 Detailed design of the interfaces is in good progress and its
status is almost completely documented in the subunit ICDs
Points to be worked on
 Final vibration loads for the subunits needed
 Documentation status has to be adapted to the current
development status
