Vertical Tail Volume Ratio 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 V_v indicates a more stable aircraft, while a lower ratio suggests potential issues with stability. The formula to calculate Vertical tail Volume ratio as follows:

$Where:$

• V_v​ is the vertical tail volume ratio,
• l_v​ is the vertical tail moment arm in m,
• S_v​ is the vertical tail area in m²,
• $S$ is the wing reference area in m²,
• $b$ is the wingspan in m.
