Advantages and Disadvantages: Triple Spool vs Double Spool Engines
Hi guys,
Now I know there are some threads on this, and I have searched/read them all but there are a lot of contradictory answers.
As far as I know the advantages of a triple spool engine are:
- Turbines run closer to optimum speeds
- More efficient
- Easier to start
Advantages of double spool engines are:
- Lighter
- Simpler design
- Lower manufacturing cost
These seem to be the only factors that are commonly pointed out. Seeing as double spools are still made today, surely there are more to go in each of the engine categories?
I look forward to some feedback.
Cheers
