As for the turbo-compounding of aircraft engines, the amusing part is that the engineers eventually figured out that the turbine was more efficient if they removed the piston engine altogether - and so the turboprop was born :-) |
Actually the Napier nomad was more efficient than a turbo prop. The turbo prop has the advantage of using less refined hence cheaper fuel. It also has the advantage of less complexity and less wear and tear due to lack of recipricating motion. A turbo prop is more economical but not more fuel efficient.
