Sideslip Angle Given By Vertical Tail 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:

• N_v is the Moment produced by vertical tail Nm,
• l_v​ is the vertical tail moment arm in m
• C_v​ is the Vertical tail lift curve slope in 1/rad,
• Q_v is the dynamic pressure of vertical tail in Pa,​
• S_v is the Vertical tail area in m².
• σ is the sidewash angle in radian.
• β is the sideslip angle in radian.
