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:
- αv is the Vertical tail angle of attack in radian,
- σ is the Sidewash angle in radian.
- β is the Sideslip angle in radian.
