Calculate Propeller Angle



Formula

The formula to calculate the Propeller Angle is:

\[ θ = \arctan\left(\frac{P}{\pi D}\right) \times \left(\frac{180}{\pi}\right) \]

What is a Propeller Angle?

The propeller angle, also known as the blade angle, is the angle between the chord line of a propeller blade and the plane of rotation. This angle is crucial in determining the efficiency and performance of the propeller. A higher blade angle generally means a higher pitch, which can lead to greater thrust but may require more power to turn the propeller. Conversely, a lower blade angle usually results in a lower pitch, which can be easier to turn but may produce less thrust. Understanding and calculating the propeller angle is essential for optimizing the performance of marine and aviation propellers.

Example Calculation

Let's assume the following values:

Using the formula:

\[ θ = \arctan\left(\frac{20}{\pi \times 10}\right) \times \left(\frac{180}{\pi}\right) \approx 32.48 \text{ degrees} \]

The Propeller Angle is approximately 32.48 degrees.
