STEP PFM

 

(1) After confirmation of the slippage during the STEP PQM vibration tests, it was decided that STEP follows a PFM approache for

 

the vibration tests. (a) In order to mitigate the slippage in PFM, some interface bolts were changed to increase the compression

 

force between the relevant subassemblies. (b) Also, the notching that had been applied for PQM was modified in Z-axis vibration

 

to mitigate any damage risk to the flight hardware. After all, the vibration tests on STEP PFM were performed

 

successfully from 25th to 27th of May 2016.
