Abstract

本发明属于航空技术领域,本发明的目的是提高飞机螺旋桨的牵引力或直升机旋翼的升力。本发明的特征是将平掠旋翼和前掠旋翼结合在一起,构成一个新的高效率的旋翼。本发明可应用在飞机的螺旋桨和直升机的旋翼上或其它应用螺旋桨产生拉力的动力装置上。

Description

一种将飞机牵引力增大29%的方法
本发明属于航空技术领域
本技术具有新颖性、创造性和实用性,本人查看了有关飞机螺旋桨和直升机旋翼的布局、设计的手册及书刊,未发现有应用本发明的迹象。
本发明的目的是提高飞机螺旋桨的牵引力或直升机旋翼的升力。
附图说明:1、桨毂 2、平掠旋翼 3、前掠旋翼
本人经过多次的实验发现:一、将平掠旋翼前掠,升力就会增大,当旋翼前掠至90°时,升力增到最大;二、将旋翼任意分成两部分,远离马达的那部分前掠90°,升力也会增大,当前掠旋翼与平掠旋翼长度相等时,升力增到最大,这时,升力约增大29%左右。
采用本发明方法制造的旋翼要比普通旋翼产生的升力大,并且省油。
