上述参数中R-T曲线的Y坐标值以字母YA标识、T-S曲线的Y坐标值以字母YB标识、S-P曲线的Y坐标值以字母YC标识,将上述各Y坐标点用光滑曲线连接起来，即得到所述外侧翼型曲线。上述参数X值和Y值具有相同的长度单位,在实际使用时根据风机规格不同，选取合适的长度单位毫米、厘米或米，将上述坐标值参数按比例缩放即可得到所用叶片外侧翼型曲线的实际尺寸。图3所示的实心叶片，选择长度单位为厘米，将上述坐标值参数按比例扩大50倍，选用厚度为1厘米的板材，则该实心结构叶片的长度为50厘米。对于实心结构叶片，以外侧翼型曲线的实际尺寸对板材进行成型加工，成型加工完成后内侧翼型曲线自然生成，然后再加工出叶片的起点过渡圆弧和终点过渡圆弧。对于空心框架结构叶片，确定长度单位，根据坐标值参数按比例缩放得到叶片外侧翼型曲线的实际尺寸，再以叶片的厚度尺寸为间距做出外侧翼型曲线的等距线，该等距线即为内侧翼型曲线，然后根据外侧翼型曲线和内侧翼型曲线加工蒙皮和框架，经过装配组成形成空心框架结构叶片。
参看图5，这是本实用新型叶片用于H型垂直轴风力发电机的示意图，各叶片经横臂与旋转主轴与固定连接。各叶片的结构相同，各叶片相对旋转主轴均匀配制，图5所示为三叶片的H型垂直轴风力发电机。
在使用相同电机及负载、风轮直径高度相同、叶片弦长相同的条件下，采用现有叶片的风力发电机与采用本实用新型叶片的风力发电机对比试验结果如下：
风速（M/S）     现有风力发电机转速（r/min）   采用本实用新型叶片的风力发电机转速（r/min）
≤1                  /                          1 
1-2                 /                           3
2-3                 2                          12
3-4                 8                           14

由上述试验结果可以看出，采用本实用新型叶片的风力发电机低风速转速明显高于现有风力发电机，且随风速增加风力发电机转速持续提高。
本实用新型叶片的优良性能源于其外侧翼型曲线、内侧翼型曲线的设计，以下以外侧翼型曲线1为例说明其作用机理：仍参看图2，当风从Y轴向吹向叶片翼形时，则， R-T、T-S曲线为迎风曲线，风经过R-T、T-S 曲线上的T点分为两个方向流动，即R-T和T-S，因为R-T曲线比T-S 曲线长，弧度变化小，气流在R-T曲线离散速度慢， R-T曲线的空气压力比经过T-S曲线的时间长且大，所以风会吹动叶片向X轴向运动。当风从Y轴逆向吹向叶片翼形时，则R-T、S-P曲线为迎风曲线，T-S曲线因为S-P曲线的阻挡只有部分迎风，当空气经过S-P曲线的P点分成两个方向的气流，一部分向S-P向，其余经过P点继续吹向R-T、T-S曲线。当气流到达R-T、T-S曲线因为R-T、T-S曲线的阻挡，气流无法通过，则会转向R-T向流动，会给S-P、T-S曲线形成的钩状内以较大的压力，这个压力大于S-P向的阻力，则会推动叶片往X轴向运动。当风从X轴向吹过，S-P、T-S曲线形成的钩状面会阻挡空气流动，则S-P、T-S曲线形成的钩状内气压会大于钩状外气压，则叶片会沿X轴向运动。X轴向吹过的风，经过R-T曲线时，会在R点分流，一部分会继续往R-T、T-S、S-P曲线形成的钩状内流动，一部分沿R-T方向在弧外流动，因为R-T曲线为弧形线，在弧外沿R-T方向流动的空气，会在弧面上形成较大的气压， 这个压力在接近T点达到最大。而且弧内的空气过R点后，会在弧内空腔离散，密度降低，压力变小，则与弧外的压力形成压力差推动叶片往X轴向运动。
