“Nonsense, where are you getting your information from? Parts count is high, not low: Say 16 blades in the compressor, 24 in the turbine. Each blade in the turbine is very expensive to produce, using high-temperature alloys which are also very hard.”
Have you ever seen an exploded view of a 4 cycle engine and automatic transmission?
I stated that there would be a trade off in increased cost of materials versus decreased amount of material needed.
An automatic transmission has a lot of parts, but why throw that in, it’s apples and watermelons. The turbine will need gearing too.
