Main Question or Discussion Point

Actually, we have three spool, two spool engine and single spool engines, how about the four spool engine? did anyone came across the design of four spool engine? I think adding an extra spool leads to increase in engine weight and becomes more complex in its mechanism.

'No' I have never come across a 4 spool engine, and yes it would be more complicated and causes lots of maintenance problems for a four spool engine, I would better suggest to discuss about a three spool or two spool engine in this thread.
Major advantage of triple spool design is it's ability to minimize engine surges thus they are the most efficient engine flying.
