The formula to calculate the Gust Factor (GF) is:
\[ GF = GWS - SWS \]
Where:
A gust factor is a simple measurement of the difference between sustained wind speeds and gusting wind speeds on a given day. The gust factor is used by aircraft to adjust for landing parameters on windy days.
Let's say the gust wind speed (GWS) is 30 knots, and the sustained wind speed (SWS) is 20 knots. Using the formula:
\[ GF = 30 - 20 = 10 \text{ knots} \]
So, the gust factor (GF) is 10 knots.
Definition: Calculates the gust load factor based on wind speeds.
Formula: \( GF = GWS - SWS \)
Example: \( GF = 40 - 25 \)
Definition: The gust effect factor accounts for the dynamic response of structures to wind gusts.
Formula: \( G = \frac{qG C_p - q_i (GC_{pi})}{q} \)
Example: \( G = \frac{0.00256 \times 1.0 \times 0.8 - 0.00256 \times 0.5}{0.00256} \)
Definition: Calculates the gust factor based on wind speed measurements.
Formula: \( GF = \frac{GWS}{SWS} \)
Example: \( GF = \frac{30}{20} \)
Definition: Calculates the load factor considering gusts.
Formula: \( LF = 1 + \frac{GF}{2} \)
Example: \( LF = 1 + \frac{15}{2} \)
