摘要
本文介绍了旋翼翼型对铰链力矩影响的研究。计算并测量了三种具有不同翼型的桨叶在悬停状态下的铰链力矩。表明旋翼翼型对铰链力矩的影响是大的。此外,还通过计算研究了悬停状态下桨叶剖面弦向质心位置对铰链力矩的影响。表明桨叶剖面弦向质心位置越靠后铰链力矩的负值越小,而且随着旋翼拉力的增大影响也增大。
This paper describes a investigation of the effect of rotor blade airfoil on hinge moment.The hinge moments of three blades with different airfoils in hover have been calculated and measured.They show that this effect is large.In addition,the effect of blade section mass center position on hinge moment in hover were calculated.Results show the nose - down moment will be smaller when blade section mass center is more close to lail edge.Additionally,the more roolor thrust is ,the less the mose - down moment is.
