Since they first entered military and commercial service during the 1950's, U.S.-manufactured turbopropeller engines have proved to be reliable, fuel-efficient propulsion systems for aircraft. Despite their somewhat greater mechanical complexity when compared with turbofans, the repair and maintenance costs of the turboprops compare very favorably with those of the other types, and their substantially reduced fuel consumption and low noise level merit serious consideration for aircraft in an energy and environmentally critical future. Advancements in propeller/fan aerodynamic and structural technologies now permit flight speeds up to Mach 0.85, making turly cost-effective aircraft possible, while retaining present standards of passenger comfort and powerplant reliability.
