Here is how the Angle of Attack at Tail equation looks like.

0.77 = 0.083 - 0.078 - 0.095 + 0.86

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

0.77 = 0.083 - 0.078 - 0.095 + 0.86

Angle of Attack at Tail Solution

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

FIRST Step Consider the formula

α t = α w - 𝒊 w - ε + 𝒊 t

Next Step Substitute values of Variables

∴

α t = 0.083rad - 0.078rad - 0.095rad + 0.86rad

Next Step Prepare to Evaluate

∴

α t = 0.083 - 0.078 - 0.095 + 0.86

LAST Step Evaluate

∴

α t = 0.77rad

How to Evaluate Angle of Attack at Tail?

Angle of Attack at Tail evaluator uses Horizontal Tail Angle of Attack = Wing Angle of Attack-Wing Incidence Angle-Downwash Angle+Tail Incidence Angle to evaluate the Horizontal Tail Angle of Attack, Angle of Attack at Tail is a measure of the angle between the horizontal tail and the oncoming airflow, calculated by subtracting the wing incidence angle and downwash angle from the wing angle of attack, and adding the tail incidence angle, providing a crucial parameter in aircraft design and aerodynamic analysis. Horizontal Tail Angle of Attack is denoted by α_t symbol.
