The dynamic pressure at the vertical tail refers to the aerodynamic force exerted by the air on the tail surfaces of an aircraft during its motion. It is a measure of the airspeed-related impact on the tail and plays a crucial role in determining the aerodynamic forces and moments that affect the stability and control of the aircraft. The formula to calculate dynamic pressure as follows:
Where:
- ηv is the Vertical tail efficiency,
- Qw is the Wing dynamic pressure in pa.
