Vertical Tail Efficiency Calculator

Vertical Tail Efficiency (ηv) assesses how efficiently the vertical tail (fin) contributes to an aircraft’s stability and control. It’s a dimensionless aerodynamic parameter, calculated as the ratio of dynamic pressure at the vertical tail to that at the wing. Higher ηv values signify a more effective vertical tail, enhancing overall aerodynamic performance and stability. The formula to calculate Vertical Tail Efficiency as follows:

Where:

  • is the dynamic pressure at the vertical tail in pa.
  • is the dynamic pressure at the wing in pa.
  • ηv is the Vertical tail efficiency.
