Here is how the Angle of Attack of Wing equation looks like.

0.083 = 0.77 + 0.078 + 0.095 - 0.86

0.083rad = 0.77rad + 0.078rad + 0.095rad - 0.86rad

0.083 = 0.77 + 0.078 + 0.095 - 0.86

Angle of Attack of Wing Solution

Follow our step by step solution on how to calculate Angle of Attack of Wing?

FIRST Step Consider the formula

α w = α t + 𝒊 w + ε - 𝒊 t

Next Step Substitute values of Variables

∴

α w = 0.77rad + 0.078rad + 0.095rad - 0.86rad

Next Step Prepare to Evaluate

∴

α w = 0.77 + 0.078 + 0.095 - 0.86

LAST Step Evaluate

∴

α w = 0.083rad

How to Evaluate Angle of Attack of Wing?

Angle of Attack of Wing evaluator uses Wing Angle of Attack = Horizontal Tail Angle of Attack+Wing Incidence Angle+Downwash Angle-Tail Incidence Angle to evaluate the Wing Angle of Attack, Angle of Attack of Wing is a measure of the angle between the wing and the oncoming airflow, calculated by adding the horizontal tail angle of attack, wing incidence angle, and downwash angle, and then subtracting the tail incidence angle, which is crucial in aerodynamics to determine the wing's performance and stability. Wing Angle of Attack is denoted by α_w symbol.
