Turbofan vs. Turboprop: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 20, 2024
Turbofan is a type of jet engine using a fan for increased efficiency; Turboprop is a jet engine with a propeller, offering better performance at lower speeds.
Key Differences
A turbofan engine combines a large fan at the front with a core jet engine, harnessing thrust from both the fan and exhaust gases. A turboprop engine uses a jet engine to drive a propeller, offering a hybrid of jet and propeller technologies.
Turbofan engines are highly efficient at high speeds and altitudes, commonly used in commercial airliners. In contrast, turboprop engines excel in fuel efficiency at lower speeds and altitudes, making them ideal for regional and cargo aircraft.
Turbofan engines typically produce less noise due to the fan, making them favorable for commercial air travel. Turboprops, with their distinctive propeller noise, are more common in smaller planes and in areas with less stringent noise regulations.
The turbofan engine’s complex design often leads to higher maintenance costs compared to turboprops. Turboprop engines, while still intricate, are generally considered simpler and more cost-effective to maintain.
Turbofan engines are predominant in large, long-range jets, reflecting their high-speed efficiency. Turboprops are often found in shorter-range, smaller aircraft, especially where short takeoff and landing capabilities are beneficial.
