Abstract
水平轴的轮毂包含转子,所述转子通过它们自己的轴基于对数螺旋形承载元件在径向方向而被刚性地连接,上述承载元件根据冲压的力旋转,且当它在围绕它的风流中旋转时,产生侧向气动力,该侧向气动力由于马格努斯效应而产生;其总量形成水平轴的旋转力矩。
Description
多转子风力发动机及其运转方法涉及风力工程,并意味着用于将风流动能转换成旋转机械能。
多转子风力发动机是风力驱动式水平轴轮,其中所述水平轴轮的轮毂包括转子风力发动机的径向上固定的轴,该固定轴具有对数螺旋形承载元件。
多转子风力发动机的工作原理基于同时使用风流搅动径向转子的冲压的力和侧向气动力,所述侧向气动力由于当各径向转子在包围它们的风流中旋转时的马格努斯效应(Magnus effect)而产生。这些力的联合作用产生水平轴的旋转力矩。
已知的是螺旋桨式水平轴风力发动机,所述螺旋桨式水平轴风力发动机包括固定的径向叶片,该叶片由风流的冲压的力和侧向气动力产生旋转能,当叶片周围有风流时,上述侧向气动力的小部分出来/参考文献1,78页-87页/。然而,通过螺旋桨式风力发动机传送到水平轴的旋转力矩的组合值有很多地方不能令人满意。
已知的是包括圆柱形径向转子的风力发动机,其中径向转子的旋转由湍流增进器提供,所述湍流增进器取安装在旋转缸体的外侧上的管件形式/参考文献2/。但由于其结构复杂性及其低效率,所以这些装置没有推广。
所提出的发明目的在于创造大功率风力发动机,所述大功率风力发动机能在各式各样风速下提供把动能转变成机械能的高效率。
为了达到这个目的,考虑使用的径向承载元件是转子,所述转子本身在竖直轴风力发动机中已被认可,其中其承载元件成形为像对数螺旋形弧一样,并能在工作的转子装置上在没有使用任何外部能量或任何其它辅助结构的情况下直接根据风流而使结构有效旋转/参考文献3/。
然而,如果在竖直结构中使用,则这些转子不能用于水平轴风力发动机,因为当转子绕水平轴连续地旋转时,只有一个排放喷嘴的存在不能提供径向转子的绕自己的轴线的旋转速度的一致性,所述一个排放喷嘴用以放出足以用于在竖直位置提供技术处理的使用过的气团。它们的角速度停止,因此所产生的侧向气动力下降。
为了弥补这种不足,将各转子的端平面装备有相同对称的排放喷嘴,这样形成本发明的精髓。
图1示出多转子风力发动机的视图,而在图2和3中示出径向转子的剖视图。
标号表示:
1 径向转子的轴线;
2 水平轴线的轮毂;
3 外部附件的边缘;
4 径向转子的承载元件;
5 径向转子的排放喷嘴;
6 径向转子的空气收集器;
7 径向转子的空气输送管道;
8 端板。
进入径向转子的空气收集器6的风流通过它们的压力的力影响承载元件4,并绕自己的轴1而传动径向转子,上述轴1刚性安装在水平轴的轮毂2和风轮3的外边缘中。随着径向转子在围绕它们的风流中旋转,由于马格努斯效应而出现侧向气动力/参考文献4,201页/,被旋转的径向转子的数量所限定的其总量,使风轮移动,从而产生水平轴的强大的旋转力矩。
来自空气收集器6的风流的风团进入空气输送管道7,并通过喷嘴5流出进入所述介质中。沿着各径向转子的端平面而存在的相同的对称的排放喷嘴不论它们在风轮旋转方式中的空间中的位置如何都能提供均匀的气团流;且产生的侧向气动力以及因此而产生的能力被永久保持。
利用便宜的材料和部件,作者发明了多转子风力发动机的有效模型并对其进行了试验。试验结果清楚地证明了将自然风流的动能转换成高功率旋转的机械能的高效率,在最低风速下的工作能力是所有类似用途的已知装置都达不到的。
