Angle of incidence of wing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wing Incidence Angle = Wing Angle of Attack-Horizontal Tail Angle of Attack-Downwash Angle+Tail Incidence Angle
𝒊_w = α_w-α_t-ε+𝒊_t
This formula uses 5 Variables

Variables Used

Wing Incidence Angle - (Measured in Radian) - The Wing Incidence Angle refers to the angle between the chord line of the wing and the longitudinal axis (or fuselage reference line) of the aircraft.
Wing Angle of Attack - (Measured in Radian) - The Wing Angle of Attack (AoA) refers to the angle between the chord line of the wing and the direction of the relative airflow.
Horizontal Tail Angle of Attack - (Measured in Radian) - The Horizontal Tail Angle of Attack (AoA) refers to the angle between the chord line of the horizontal stabilizer (including the elevator) and the relative airflow.
Downwash Angle - (Measured in Radian) - Downwash Angle is the angle formed between the direction of air movement as it approaches an airfoil and as it leaves it.
Tail Incidence Angle - (Measured in Radian) - Tail Incidence Angle is the angle between the reference chord of the horizontal tail and the fuselage reference line.

STEP 1: Convert Input(s) to Base Unit

Wing Angle of Attack: 0.083 Radian --> 0.083 Radian No Conversion Required

Angle of incidence of wing

Go Wing Incidence Angle = Wing Angle of Attack-Horizontal Tail Angle of Attack-Downwash Angle+Tail Incidence Angle

Angle of Attack at Tail

Go Horizontal Tail Angle of Attack = Wing Angle of Attack-Wing Incidence Angle-Downwash Angle+Tail Incidence Angle

Angle of Attack of Wing

Go Wing Angle of Attack = Horizontal Tail Angle of Attack+Wing Incidence Angle+Downwash Angle-Tail Incidence Angle

Downwash angle

Go Downwash Angle = Wing Angle of Attack-Wing Incidence Angle-Horizontal Tail Angle of Attack+Tail Incidence Angle

Angle of incidence of wing Formula

Wing Incidence Angle = Wing Angle of Attack-Horizontal Tail Angle of Attack-Downwash Angle+Tail Incidence Angle
𝒊_w = α_w-α_t-ε+𝒊_t

Why is angle of incidence important?

The angle of incidence defines your angle of attack until you have enough speed (and tail downforce) to lift your nose off. And, the angle of incidence reduces your pitch angle, giving you better visibility during takeoff.

How to Calculate Angle of incidence of wing?

Angle of incidence of wing calculator uses Wing Incidence Angle = Wing Angle of Attack-Horizontal Tail Angle of Attack-Downwash Angle+Tail Incidence Angle to calculate the Wing Incidence Angle, The Angle of Incidence of Wing is a measure of the angle between the wing's leading edge and the oncoming airflow, calculated by subtracting the horizontal tail angle of attack and downwash angle from the wing angle of attack, and adding the tail incidence angle, which is critical in aircraft design to ensure stable flight. Wing Incidence Angle is denoted by 𝒊_w symbol.

How to calculate Angle of incidence of wing using this online calculator? To use this online calculator for Angle of incidence of wing, enter Wing Angle of Attack (α_w), Horizontal Tail Angle of Attack (α_t), Downwash Angle (ε) & Tail Incidence Angle (𝒊_t) and hit the calculate button. Here is how the Angle of incidence of wing calculation can be explained with given input values -> 0.085 = 0.083-0.77-0.095+0.86.
