[PSUBS-MAILIST] Thruster Test Jig

[Cliff Redus via Personal_Submersibles]

Alan, I sent you a compressed file to your private email address.

Basics of the tester was a hinged boom that lowers the thruster into the
pool.  The bollard thrust was measured with a load cell.  Thruster speed
was measured with a mag pick up on a shaft and a frequency input module in
PLC.  PLC was used to take measured analog signals and data logging.
Touchscreen HMI was used to control and display results.  System used three
100 Ah batteries connected in series to drive thruster.  Also measured the
current and voltage on thurster.  Included a power point file of a psub
presentation I did on the test a while back.

I am interested in the results you get from your thruster.  Keep us in
abreast of testing progress.

Regards

Cliff
