Vertical tail volume ratio Formula Elements

Variables
Vertical Tail Volume Ratio
Vertical Tail Volume Ratio relates to the area of the vertical tail, the distance between the centroid of vertical tail area and aircraft's e.g., the wing area, and the wingspan.
Symbol: Vv
Measurement: NAUnit: Unitless
Note: Value should be greater than 0.
Vertical Tail Moment Arm
The Vertical Tail Moment Arm is the distance between the centroid of the vertical tail shape and the center of gravity of the aircraft.
Symbol: 𝒍v
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Vertical Tail Area
The Vertical Tail Area is the area of the surface of the vertical tail, including the submerged area to the fuselage centerline.
Symbol: Sv
Measurement: AreaUnit:
Note: Value should be greater than 0.
Reference Area
The Reference Area is arbitrarily an area that is characteristic of the object being considered. For an aircraft wing, the wing's planform area is called the reference wing area or simply wing area.
Symbol: S
Measurement: AreaUnit:
Note: Value should be greater than 0.
Wingspan
The Wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip.
Symbol: b
Measurement: LengthUnit: m
Note: Value should be greater than 0.

How to Evaluate Vertical tail volume ratio?

Vertical tail volume ratio evaluator uses Vertical Tail Volume Ratio = Vertical Tail Moment Arm*Vertical Tail Area/(Reference Area*Wingspan) to evaluate the Vertical Tail Volume Ratio, Vertical tail volume ratio is a dimensionless parameter that represents the effectiveness of the vertical tail in providing stability and control to an aircraft, calculated by dividing the product of the vertical tail moment arm and area by the reference area and wingspan. Vertical Tail Volume Ratio is denoted by Vv symbol.
