Mystery object on the QE2
« on: Mar 01, 2017, 07:53 PM »
Scanning some old family photos tonight, and came across 1985 ones of Dad on the QE2 in Lisbon.

Attached is whatever it is he was working on, I think, but what is it?

Could it be something to do with an electric motor? Looks like a coil of some kind.


Don't hold me to it, been some time since I have done anything electric related, but it just came into my mind.

Thought they looked like thrust faces!
(and that's from a dumb sparky engineer guy)

Where are they situated in the LP Turbine ?  What do they do ? And how do they do it ?

Thanks !   :)

Low pressure turbine.
Each main engine turbines have a high pressure turbine 850psi which exhausts into the low pressure turbine which is around 80psi
Each turbine develops a lateral thrust which has to be absorbed by a thrust bearing which is full of oil, so the thrust is cushioned by a film of oil between the shaft collar and pads.
In 1985 we were getting over a series of failures , due to contaminated Lub oil from bacteria and some misalignment issues.

Thanks very much for the information. Could you please tell me if the failure was sudden or gradual ? And how did you repair it ? Were the misalignment issues due to wear and tear or were they inherent in the design ?
