1.一种全工况条件下高升力低力矩特性12％厚度旋翼翼型，其特征在于：所述翼型上下表面几何坐标(x，y)表达式分别为：

$\frac{y_{up}}{C}=0.0025\left(\frac{x}{C}\right)+{\left(\frac{x}{C}\right)}^{0.5}\left(1-\frac{x}{C}\right)\·\underset{i=0}{\overset{6}{\mathrm{\Σ}}}\left(A_{{\mathrm{up}}_i}\·\frac{6!}{i!\left(6-i\right)!}{\left(\frac{x}{C}\right)}^i{\left(1-\frac{x}{C}\right)}^{6-i}\right)$

其中下标up和low分别表示翼型的上、下表面，C为翼型弦长，系数为：

$A_{{\mathrm{up}}_0}=0.182*(1\±0.5\%),A_{{\mathrm{up}}_1}=0.343*(1\±0.5\%),A_{{\mathrm{up}}_2}=0.0425*(1\±0.5\%),$

$A_{{\mathrm{up}}_3}=0.350*(1\±0.5\%),A_{{\mathrm{up}}_4}=0.103*(1\±0.5\%),A_{{\mathrm{up}}_5}=0.238*(1\±0.5\%),$

$A_{{\mathrm{up}}_6}=-0.0545*(1\±0.5\%);$

$A_{{\mathrm{low}}_0}=-0.118*(1\±0.5\%),A_{{\mathrm{low}}_1}=-0.0694*(1\±0.5\%),A_{{\mathrm{low}}_2}=-0.100*(1\±0.5\%),$

$A_{{\mathrm{low}}_3}=-0.150*(1\±0.5\%),A_{{\mathrm{low}}_4}=2.33*(1\±0.5\%),A_{{\mathrm{low}}_5}=-0.242*(1\±0.5\%),$

$A_{{\mathrm{low}}_6}=-2.50*(1\±0.5\%).$

$A_{{\mathrm{up}}_4}=0.1031169,A_{{\mathrm{up}}_5}=0.2385890,A_{{\mathrm{up}}_6}=-0.0545979;$

$A_{{\mathrm{low}}_0}=-0.118319,A_{{\mathrm{low}}_1}=-0.069490,A_{{\mathrm{low}}_2}=-0.1000549,A_{{\mathrm{low}}_3}=-0.1507907,$

$A_{{\mathrm{low}}_4}=2.3304491,A_{{\mathrm{low}}_5}=-0.2426400,A_{{\mathrm{low}}_6}=-\mathrm{2.5073795.}$
