Downwash velocity component at a certain angle Calculator

The downwash ($w$) is the vertical component of the velocity resulting from the generation of lift by the lifting body. As the airfoil or wing generates lift, it induces a circulation ($\Gamma$) around its surface. This circulation is related to the lift and the circulation distribution along the wing span. The downwash velocity decreases with distance from the lifting body (increasing $\theta$), and it becomes zero far away from the body. 

• w(θ0​) is the vertical component of the velocity (downwash) at a specific angle θ0​ behind the lifting body,
• Γ0​ is the maximum circulation (strength of the circulation distribution),
• $b$ is the wing span
