Description
本发明涉及垂直起降飞行器备技术领域,具体涉及一种主动主旋翼垂直起降飞行器。
众所周知,直升机包括机身、安装在机身中间部位的顶部上的主旋翼、以及用于抵消从主旋翼传递至机身的扭矩的反扭矩尾部旋翼。
铰接的主旋翼和/或反扭矩旋翼也是已知的。更为具体地,铰接的旋翼包括围绕第一轴线旋转的驱动轴、与驱动轴一体地围绕第一轴线旋转的桨毂、以及从桨毂上沿相对于第一轴线的为径向的各第二轴线伸出的多个桨片。
各桨片可相对于桨毂围绕各自的第二轴线旋转,以改变其相对于气流的冲击角度,并可相对于桨毂围绕各自的第三轴线自由的振荡,以进行所谓的拍翼运动。各第三轴线与相关桨片的第一和第二轴线交叉。
各桨片还相对于桨毂和其它桨片围绕平行于第一轴线的各自的第四轴线自由的振荡,以进行所谓的摇摆(lead-lag)运动。
在此领域内出现了这样一种需求:在不削弱旋翼自身的空气动力性能的情况下,在驱动轴围绕第一轴线的旋转速度的大范围内减弱桨片的摇摆运动所产生的振动。
目前,机直升机产生动力是通过内置发动机提供动力,常用发动机类型有燃油发动机、汽缸活塞式发动机或涡轮式发动机,发动机将旋转动力提供给一种立式平行转轴,该立式平行转轴的输出端一头连接六支单体的螺旋桨,使该六支单体的螺旋桨片水平转动起来,这样,螺旋桨片切割其上方静止空气,被切割后的静止空气便产生了一个向 下流动的空气流,同时空气流对螺旋桨产生向上的升力,在这样的作用力与反作用力的作用下,直升机升上空中。
现有直升机旋翼的动力都只是由发动机,通过垂直起降飞行器主旋翼变距***将动力传送给主旋翼,由于直升机的主旋翼较长,因此其客服空气阻力所需要的扭矩也会很大。
