Production of Petal Mechanics
.Petal plates (EUROCOMPOSITE) to be made with
T300 skins (45/-45)
Second skins (FVT) are M40 (0/90) and are
available
Arrangement gives good stability in all directions
First 2 plates (10 petals) expected next week
prototype petals will be checked
for stability (mount petal at 0/45/90
orientation and hang weight of 2kg)
.Ti-pipes for cooling circuit all delivered
bending jigs (FP and BP) available
.Manifolds redesigned (simplified) material SS
and in one piece
Waiting for welding trials to the Ti-cooling pipes
.Inserts (all types) in hand and electrically
insulating! Gluing jigs (FP and BP) ready
.Small parts in hand
Conclusion Petal production can start as soon as
welded manifolds exist

Tests/Quality control during petal production
1/ Leak test for cooling circuit (at 3 x working
pressure 12bar)
A setup exists in Louvain, to be implemented in
Aachen
2/ Measure thermal efficiency/electrical
resistance of each insert
Measurement combined in one test setup, which is
in preparation. Results
DB
3/ Precision and Deformation measurements
Control all petals at start of production
(10-15) Sample later
Measure all insert positions on CMM (room
temperature)
Cool petal and measure inserts on CMM in cold
condition (has to be tried to see if measurement
can be done fast enough to avoid ice formation) ,
or
Optical method (setup exists but not yet taken
into operation)
4/ ICB testing operative (WK)

Request
Decide the petal types to be integrated in each
center, so that the small parts needed for petal
integration (centerliners,screws,washers,bridges,
..) and of course subsequently the other
components (modules,AOHs,) can be distributed
accordingly
