Hi barit1,
On the Trent 900 engine, the LP & IP rotors turn counter clockwise with the HP rotor turning clockwise. This enables elimination of the stationary nozzle between the HPT blade wheel and the IPT blade wheel. The only thing between the two is a sheet metal frame structure that contained the failed oil feed pipe that started the fire. The stage 1 LPT nozzle is still there, but has a significantly larger diameter due to the conical nature of the LPT.
