Vertical Tail Volume Ratio Given By Sideslip Angle Calculator

The vertical tail volume ratio  is a dimensionless parameter used in aircraft design to assess the effectiveness of the vertical tail in stabilizing the aircraft. It is calculated by dividing the vertical tail volume by the product of the wing area and the mean aerodynamic chord of the wing. A higher Vv indicates a more stable aircraft, while a lower ratio suggests potential issues with stability. The formula to calculate Vertical tail Volume ratio as follows:

Where:

  • Vv is the vertical tail volume ratio.
  • Cn is the Yawing Moment  coefficient.
  • ηv is the Vertical tail efficiency factor.
  • Cv is the Vertical tail lift curve slope in 1 per Radian.
  • β is the side-slip angle in Radian.
  • σ is the Sidewash angle in Radian.
