Quote: “When the bypass ratio is increased to 10-20 for very efficient
low speed performance, the weight and wetted area of the fan shroud
(inlet) become large, and at some point it makes sense to eliminate it
altogether. The fan then becomes a propeller and the engine is called a
turboprop. Turboprop engines provide efficient power from low speeds up
to as high as M=0.8 with bypass ratios of 50-100.” - Prof. Z. S. Spakovszky. “11.5 Trends in thermal and propulsive efficiencyArchive” MIT turbines, 2002. Thermodynamics and Propulsion

p550. Published by Tata McGraw-Hill Education. Quote: “If the cowl is
removed from the fan the result is a turboprop engine. Turbofan and
turboprop engines differ mainly in their bypass ratio 5 or 6 for
turbofans and as high as 100 for turboprop.” - Animated Engines

- Philip Walsh, Paul Fletcher. “Gas Turbine Performance“,
page 36. John Wiley & Sons, 15 April 2008. Quote: “It has better
fuel consumption than a turbojet or turbofan, due to a high propulsive
efficiency.., achieving thrust by a high mass flow of air from the
propeller at low jet velocity. Above 0.6 Mach number the turboprop in
turn becomes uncompetitive, due mainly to higher weight and frontal
area.” - “Rolls-Royce Aero Engines” Bill Gunston, Patrick Stevens Limited, ISBN 1-85260-037-3, p.147
