Washout Twist
A precise tool.
What is the Washout Twist & How does it work?
Washout is a technique used in aircraft design to delay the stall of the outer wing, thereby improving handling and stability during high angles of attack. This is achieved by twisting the wings such that the leading edge of the outer wing is slightly lower than the inner wing.
theta = frac{L}{b}
theta = washout angle, L = twist length, b = wingspan
The stall progression is influenced by the washout angle. A larger washout angle results in a more gradual stall, which enhances the aircraft’s ability to recover from stalls and improves overall safety.

Frequently Asked Questions
What is washout in aircraft design?
Washout is a technique that twists the wings so the leading edge of the outer wing is slightly lower than the inner wing, delaying stall and improving handling.
How does washout affect an aircraft’s stall progression?
A larger washout angle results in a more gradual stall, enhancing the aircraft’s ability to maintain control at high angles of attack.
What is the formula for calculating the washout angle?
The washout angle (ΞΈ) is calculated using the formula ΞΈ = L/b, where L is the twist length and b is the wingspan.
Why is washout important in aircraft design?
Washout is crucial for improving aircraft stability and handling by delaying the stall of the outer wing during high angles of attack.
Can washout be adjusted on existing aircraft?
In some cases, limited washout adjustments can be made to existing aircraft through modifications or reconfiguration, but it is generally more common in initial design stages.
What are the benefits of using washout in aircraft design?
The benefits include improved stability, better handling during high angles of attack, and a safer overall flying experience for pilots.
How does wing twist contribute to washout?
Wing twist contributes to washout by creating a difference in airfoil angle between the inner and outer wings, which delays stall progression.
