Look up "JP8" and you will realise that commercial engines and military engines are two diff animals. If you think the Trent can handle ANY fuel you are mistaken. The way this Trent is designed it gets every last bit of energy from the kerro. Yes I do believe an oil mist would disturb the cycle. We are talking micro/nano seconds.
The days of running jet engines on paraffin are gone with these new units.
They are really efficient.
Remember only about 10/15% of air coming in is used for combustion.
At TO the 972 would gulp a few gallons per SECOND
in the Qantas 388 at full load. Makes ya just slaver your chops don't it!
Not sure about overboost cause the software would start to mess with the kero supply. Hence the bad vibes and spline wear. The software will try to correct yes. But all the other parameters don't match the model..hence the stuttering and spline wear.
Did I mention overspeed? I don't think turbine oil was mixing ALL the time but I do think that at the 72K pounds the Qantas A-388 was putting out at TO it was. It would be interesting to know just how much oil had to be added after each flight.
