摘    要:本文分两大部分,即旋翼理论分析的发展(认识旋翼)及旋翼浆叶外形的发展(改造旋翼)。在第一部分中,阐述了旋翼滑流理论、叶素理论、涡流理论(其中又包括固定尾迹的经典涡流理论、预定尾迹的半经验涡流理论、自由尾迹的现代涡流理论)和旋翼CDD方法。在第二部分中,讨论了旋翼桨叶的翼型、浆尖形状、扭转角分布等的变化历程。最后,作为总结,提出了旋翼理论分析和浆叶气动外形的四代发展阶段的划分。

关 键 词:旋翼空气动力学  旋翼  涡流理论  翼型  直升飞机

Abstract:There are two parts in this paper, i.e., the progress o f the rotor theoretical analysis (understand rotor) and the progress of the roto r blade aerodynamic shape (change rotor). In the first part, the rotor slipstre am theory, b lade element theory, vortex theory (including rigid-wake classical vortex theor y, prescribed-wake semi-empirical vortex theory as well as free-wake modern v ortex theory) and rotor CFD method are described. In the second part, the histor ical developments of the rotor blade airfoil, blade tip shape and blade twist ar e reviewed. Finally, as a conclusion, four generations in the developments of th e rotor theoretical analysis and blade aerodynamic shape are presented.
Keywords:rotor aerodynamics  helicopters  rotors  vortex theory  airfoil  blade tip shape  twist angle
