Anyone familiar with this new engine ? Still 3 spools like it used to be on the B757 RB211 (N1, N2, and N3) ? or is it more like a Geared Turbofan ?
All Trents are 3-spool.
The A330neo's Trent 7000 is based on the 787's Trent 1000, with one of the major differences being the reinstatement of bleed air on the 7000 (which of course the bleedless 787 famously doesn't use).

It would be interesting to identify the flights on which crew/and or pax reported feeling ill. I wouldn't be surprised if the issue only affected one or two aircraft in TAP's 10-strong fleet.
