I have found this website that lists a lot of turboprop engines. I would like to compare them with as few values as possible. As an example, there are tons of different values that describe a jet engine, but the most important/significant values are thrust and bypass ratio. Out of the many different values for a turboprop engine, which would be the few most important/significant to include?
My goal with the data is to approximate (very roughly) comparative fuel usage.
EDIT: To clarify the question, what are the most important engine values/specifications that can be used to estimate the general fuel economy of the turboprop engine?
