Blade sweep is one of the features incorporated in Advanced Turboprop (Prop-Fan) designs. Sweep is incorporated to enhance efficiency and reduce noise. This paper discusses the theoretical basis for performance enhancement and noise reduction and discusses the experimental evidence demonstrating the value of this feature in current Prop-Fan designs. Emphasis is on single rotation Prop-Fans but benefits to counter rotation Prop-Fan designs are discussed briefly.
