Sideslip Angle Given By Vertical Tail Volume Ratio Calculator

The sideslip angle (β) is the angle between an aircraft’s longitudinal axis and the relative wind, indicating lateral deviation from coordinated flight. Crucial for maneuvering, it influences sidewash angle by altering the relative wind, impacting aerodynamic forces and aircraft stability. The formula to calculate sideslip angle as follows:

Where:

• C_n​ is the Yawing Moment Coefficient,
• V_v​ is the Vertical Tail Volume Ratio.
• η_v is the vertical tail efficiency,
• C_v is the Vertical tail lift curve slope in 1/rad,
• σ is the sidewash angle in radian.​
