Ground effect factor Solution

Follow our step by step solution on how to calculate Ground effect factor?

FIRST Step Consider the formula

ϕ = \frac{{(16 \cdot \frac{h}{b})}^{2}}{1 + {(16 \cdot \frac{h}{b})}^{2}}

Next Step Substitute values of Variables

∴

ϕ = \frac{{(16 \cdot \frac{3m}{50m})}^{2}}{1 + {(16 \cdot \frac{3m}{50m})}^{2}}

Next Step Prepare to Evaluate

∴

ϕ = \frac{{(16 \cdot \frac{3}{50})}^{2}}{1 + {(16 \cdot \frac{3}{50})}^{2}}

Next Step Evaluate

∴

ϕ = 0.479600333055787

LAST Step Rounding Answer

∴

ϕ = 0.4796

How to Evaluate Ground effect factor?

Ground effect factor evaluator uses Ground Effect Factor = ((16*Height from Ground/Wingspan)^2)/(1+(16*Height from Ground/Wingspan)^2) to evaluate the Ground Effect Factor, Ground Effect Factor is a measure of the increased lift and reduced drag experienced by an aircraft or airplane wing when it operates close to the ground, resulting in improved takeoff and landing performance. Ground Effect Factor is denoted by ϕ symbol.

How to evaluate Ground effect factor using this online evaluator? To use this online evaluator for Ground effect factor, enter Height from Ground (h) & Wingspan (b) and hit the calculate button.

FAQs on Ground effect factor

What is the formula to find Ground effect factor?

The formula of Ground effect factor is expressed as Ground Effect Factor = ((16*Height from Ground/Wingspan)^2)/(1+(16*Height from Ground/Wingspan)^2). Here is an example- 0.4796 = ((16*3/50)^2)/(1+(16*3/50)^2).

How to calculate Ground effect factor?

With Height from Ground (h) & Wingspan (b) we can find Ground effect factor using the formula - Ground Effect Factor = ((16*Height from Ground/Wingspan)^2)/(1+(16*Height from Ground/Wingspan)^2).
