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 Pitching moment?

Pitching moment evaluator uses Pitching Moment = Pitching Moment Coefficient*Dynamic Pressure*Reference Area*Characteristic Length to evaluate the Pitching Moment, The pitching moment is a measure of the turning force around a pitch axis, typically used to describe the rotational motion of an object, such as an aircraft or a ship, and is critical in understanding the stability and control of the vehicle, it is an essential concept in aerodynamics and naval architecture. Pitching Moment is denoted by 𝑴 symbol.

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

FAQs on Pitching moment

What is the formula to find Pitching moment?

The formula of Pitching moment is expressed as Pitching Moment = Pitching Moment Coefficient*Dynamic Pressure*Reference Area*Characteristic Length. Here is an example- 17.9832 = 0.59*10*5.08*0.6.

How to calculate Pitching moment?

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

Can the Pitching moment be negative?

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

Which unit is used to measure Pitching moment?

Pitching 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 Pitching moment can be measured.
