The Choice of Twist Calculator in aircraft wing design, often referred to as wing twist or washout, is a crucial decision that affects an aircraft’s aerodynamic performance and stability. Wing twist refers to the variation in the angle of incidence along the span of the wing, with the root (near the fuselage) having a different angle of incidence compared to the wingtip.
Formula: The twist angle (often denoted as δ) is typically calculated using the following formula:
- δ is the twist angle (in degrees).
- α_root is the angle of incidence at the wing’s root (in degrees).
- α_tip is the angle of incidence at the wing’s tip (in degrees).
