The design trend is there: 8, 4, 3, 2 jet engines on powering the large cargo or passenger aircraft. Is it mostly to accommodate the larger, more efficient fans, or are there also benefits in the combustion cycle?

Jets seem more immune to the issues of excess heat removal that their piston engine predecessors suffered when scaled to greater size. Is there a limit to how large an axial jet engine can be? Are we approaching that limit today with engines such as the GE9X at over $130000 lbs thrust$$130 \, 000 \, \text{lbs}$ of thrust, or is there more to go?

How does increasing the size of a jet engine make it more fuel efficient?
