摘要
旋翼桨叶气动外形设计的目的主要是使旋翼的气动特性满足直升机的设计和使用要求,本文针对直升机旋翼桨叶气动外形设计中的有关问题,介绍了桨叶气动外形设计的设计方法,设计参数主要包括桨叶的弦长、扭转角、翼型选择和配置以及桨尖形状,并以某型直升机旋翼桨叶为例,介绍了旋翼桨叶气动外形的设计。
The rotor blade aerodynamic shape design is aimed at that the aerodynamic performance of the rotor must satisfy the helicopter design and employ.The blade aerodynamic shape design method was introduced in this paper in allusion to some problem of the helicopter rotor blade aerodynamic shape.Design parameters including the blade chord length,torsion angle,profile choice and disposal and the tip shape were discussed.Taking one helicopter rotor blade for example,the rotor blade aerodynamic shape design technical was introduced.
