The BSM is now in the final stages of design and intitial prototypes
are being built. Presentation. |
| Mar.01 |
An alternate prototype has also been explored to provide backup options
in the areas of the higher risk technologies of the baseline design.
Presentation. |
| Mar.01 |
SPIRE documentation is available on the ESA Livelink site |
| Apr.01 |
The BSM has been presented at the SPIRE Intermediate Instrument
Review, 23-24.April.01. Presentation. |
| Jun.01 |
The latest 3D models of the BSM have been incorporated on the
SPIRE structure by MSSL. Images are available 1 2 3 4 |
| Jul.01 |
Preparation for the DDR scheduled for 30.Jul.01 |
| Aug.01 |
Design presented at DDR level.A few items to close out but looking
good. 2 axis prototype build |
| Oct.01 |
Product Assurance plan rolled out. Presentation. |
| Jan.02 |
Development Model (DM)released for manufacture |
| Feb.02 |
Detailed 2 axis prototype warm testing completed, including
control loop tests. Preparation for cryo tests started. Kick-off meeting
on random response FEA held. Magnetic modelling underway at MPIA. Representative
Zeiss/PACS motors received. This will require a re-design of DM to accomodate
(designated DM-2). DM-1 model manufacture in an advanced state. Cryo-upscreen
rig design complete and placed with workshop for manufacture. Brazed
CuBe pivots (chop axis type) order placed with C-Flex. |
| Mar.02 |
Cryostat cold repeatability & linearity tests performed
- looks good (though needs to be confirmed with AR coated window). Problem
with noise affecting control loop - need screened wires on BSM, which
will only be available with DM-2. DM-1 started assembly. Cryo-upscreen
rigs manufactured and assembled. Tentative booking for warm vibration
tests requested with RAL work on justification/test plan in hand.. IBDR
presentation given. Draft SMEC/BSM simulator philosophy for integration
and tests discussed |
| Apr.02 |
Cryostat warm repeatability & linearity tests performed
with AR coated window PTFE coated STP/STT wire for DM-2 sourced from
RAL, common procurement of wire for future models discussed with RAL.
DM-1 assembled and fastener torque procedure detailed. Warm shake of
DM-1 and 1 off flex pivot upscreen rig completed successfully! |

DM-2 in manufacture |
| Oct.02 |
Delivery of Structural thermal model. DM-2 in warm tests. |
| Jan.03 |
Cold tests (4K) at ATC. |
| Feb.03 |
DM-2 and four flex-pivot up-screening rigs successfully passed
a cryogenic cold shake at RAL. This is a major milestone in the BSM programme,
and a measure that the design analysis and build quality are fully up
to space quality standards. |
