PACS IIDR 01/02 Mar 2001
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
