It has been brought to my attention that, at least, the British designs consist of sets of low pressure and high pressure turbines. But the logic, at least my mistaken one, is that you used them complementary. But in the British designs, let´s say, the Queen Elisabeth Class, the arragement was the following:
One low pressure ahead and one high pressure astern, in the same casing, on the inner shaft.
One high pressure ahead and one high pressure astern on the wing shaft.
In Repulse, on the other hand, we had:
Two high pressure turbines on the wing shaft
Two low pressure turbines on the inner shaft
All sets consisted of a high pressure and a low pressure turbine
It seems to me that the logic is that, at least in QE or Repulse designs all shafts must have the same arragement in order to have the same SHP and rpm. Isn´t it? Which is why I brough up Hood that is designed upon that logic.
