由於旋翼機的升力及推力皆由主旋翼負責,因此直昇機的主旋翼就扮演了重要的角色。本文的目的就是介紹歷年來直昇機主旋翼尾流力學的理論發展。首先就尾流空氣動力學的觀點介紹基本的尾流理論,如動量理論、葉片元素理論等。此外對於電腦上之應用,如自由流法也略加介紹。而對於預設尾流法及較近代之尾流理論--- Peters動力尾流理論及該理論的應用也將詳加介紹。
The development and background of rotary-wing wake dynamics has been briefly reviewed. Several basic wake aerodynamic models have been introduced. The free-wake analysis is also mentioned for the C.F. D. applications. The prescribed wake model has compared with other approach methods. A recently wake model---Peters dynamic wake model is also introduced as well as its applications in aeroelastic systems.
