\[ \tan \beta_1 - \tan \beta_2 = \frac{1.35 \left( 6.0 - \sigma \right) \sigma}{ 12.0 \cos \beta_\infty } \left( \frac{\cos \beta_\infty }{ \cos \beta_2} \right)^2 \]
\[ \tan \beta_\infty = \frac{ \tan \beta_1 + \tan \beta_2 }{2} \]
\[ \beta_\infty ベクトル平均流れ角 \]
\[ \sigma = \frac{l}{t} = \frac{1}{2} \left\{ 6.0 - \sqrt{ 6.0^2 - \frac{4 \times 12.0}{1.35} \frac{\tan \beta_1 - \tan \beta_2}{\cos \beta_\infty} \left( \cos \beta_2\right)^2} \right\} \]
