Tip Speed Ratio Calculator

Formula

The formula to calculate the Tip Speed Ratio (TSR) is:

\[ TSR = \frac{TS}{WS} \]

Where:

\( TSR \) is the Tip Speed Ratio
\( TS \) is the tip speed (mph/knots)
\( WS \) is the wind speed (mph/knots)

What is Tip Speed Ratio?

The Tip Speed Ratio (TSR) is a dimensionless quantity that represents the ratio of the speed of the tip of a wind turbine blade to the speed of the wind. It is an important parameter in the design and performance of wind turbines, as it affects the efficiency and power output of the turbine.

Example

Let's say the tip speed (TS) is 60 mph, and the wind speed (WS) is 15 mph. Using the formula:

\[ TSR = \frac{60}{15} = 4 \]

So, the Tip Speed Ratio (TSR) is 4.
