Variables

Yawing Moment

Yawing Moment is the moment acting on the airplane about its yaw axis.

Symbol: 𝑵

Measurement: Moment of ForceUnit: N*m

Note: Value can be positive or negative.

Formulas to find Yawing Moment

Yawing Moment Coefficient

Yawing Moment Coefficient is the coefficient associated with the moment that tends to rotate an airplane about its vertical (or yaw) axis.

Symbol: C_n

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Yawing Moment Coefficient

Dynamic Pressure

Dynamic Pressure is simply a convenient name for the quantity which represents the decrease in the pressure due to the velocity of the fluid.

Symbol: q

Measurement: PressureUnit: Pa

Note: Value should be greater than 0.

Formulas to find Dynamic Pressure

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: m²

Note: Value should be greater than 0.

Formulas to find Reference Area

Characteristic Length

Characteristic Length (used in aerodynamics) is a reference length characteristic of the object under consideration.

Symbol: 𝓁

Measurement: LengthUnit: m

Note: Value should be greater than 0.

How to Evaluate Yawing Moment?

Yawing Moment evaluator uses Yawing Moment = Yawing Moment Coefficient*Dynamic Pressure*Reference Area*Characteristic Length to evaluate the Yawing Moment, Yawing Moment is a measure of the rotational force that causes an aircraft to turn or yaw around its vertical axis, affected by factors such as air density, wing surface area, and length of the aircraft, it is a critical parameter in aerodynamics, influencing the stability and control of an aircraft during flight. Yawing Moment is denoted by 𝑵 symbol.

How to evaluate Yawing Moment using this online evaluator? To use this online evaluator for Yawing Moment, enter Yawing Moment Coefficient (C_n), Dynamic Pressure (q), Reference Area (S) & Characteristic Length (𝓁) and hit the calculate button.

FAQs on Yawing Moment

What is the formula to find Yawing Moment?

The formula of Yawing Moment is expressed as Yawing Moment = Yawing Moment Coefficient*Dynamic Pressure*Reference Area*Characteristic Length. Here is an example- 42.672 = 1.4*10*5.08*0.6.

How to calculate Yawing Moment?

With Yawing Moment Coefficient (C_n), Dynamic Pressure (q), Reference Area (S) & Characteristic Length (𝓁) we can find Yawing Moment using the formula - Yawing Moment = Yawing Moment Coefficient*Dynamic Pressure*Reference Area*Characteristic Length.

Can the Yawing Moment be negative?

Yes, the Yawing Moment, measured in Moment of Force can be negative.

Which unit is used to measure Yawing Moment?

Yawing Moment is usually measured using the Newton Meter[N*m] for Moment of Force. Kilonewton Meter[N*m], Millinewton Meter[N*m], Micronewton Meter[N*m] are the few other units in which Yawing Moment can be measured.
