I am trying to identify the function of two printed circuit boards from an Olympus 593 Engine Engine Control Unit (ECU). I worked on Concorde and its ECUs at Filton for many years in the 1970s and 80s.
When Concorde retired in 2003 I requested from British Airways and was given 2 ECU PCBs as a souvenir.
There were of course 8 ECUs on each aircraft, 2 per engine. Each ECU had about 20 different PCBs. I have sometimes wondered just what the function was of my 2 PCBs. Maybe someone knows or has the relevant ECU Overhaul Manual. I have already asked various organisations for help - Ultra Electronics the manufacturers of the ECUs, British Airways, Rolls-Royce Heritage Trust and some museums. I've had some helpful replies but no actual answers.
Marked on the PCBs ae their drawing numbers: 46546-629-0 and 46456-602-0.
I have tried to attach some photos but there seems to be some forum setting that's preventing this!
Thanks
