To calculate the Blade Pitch Angle (θ):
\[ θ = \tan^{-1}\left(\frac{C}{B}\right) \]
Where:
The blade pitch angle is the angle between the chord line of a blade and the plane of rotation. It is a critical parameter in the design and operation of wind turbines and propellers, as it affects the aerodynamic performance and efficiency. Adjusting the pitch angle can optimize the lift and drag forces on the blade, thereby improving the overall performance of the turbine or propeller.
Let's assume the following values:
Using the formula:
\[ θ = \tan^{-1}\left(\frac{0.5}{3}\right) \approx 9.46 \text{ degrees} \]
The Blade Pitch Angle is approximately 9.46 degrees.
Let's assume the following values:
Using the formula:
\[ θ = \tan^{-1}\left(\frac{1}{4}\right) \approx 14.04 \text{ degrees} \]
The Blade Pitch Angle is approximately 14.04 degrees.
