Disk Loading Solution

Follow our step by step solution on how to calculate Disk Loading?

FIRST Step Consider the formula

W load = \frac{W a}{\frac{π \cdot {d r}^{2}}{4}}

Next Step Substitute values of Variables

∴

W load = \frac{1000N}{\frac{π \cdot {501mm}^{2}}{4}}

Next Step Substitute values of Constants

∴

W load = \frac{1000N}{\frac{3.1416 \cdot {501mm}^{2}}{4}}

Next Step Convert Units

∴

W load = \frac{1000N}{\frac{3.1416 \cdot {0.501m}^{2}}{4}}

Next Step Prepare to Evaluate

∴

W load = \frac{1000}{\frac{3.1416 \cdot {0.501}^{2}}{4}}

Next Step Evaluate

∴

W load = 5072.64729915484N

LAST Step Rounding Answer

∴

W load = 5072.6473N

How to Evaluate Disk Loading?

Disk Loading evaluator uses Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4) to evaluate the Load, Disk Loading refers to the ratio of the total weight of an aircraft to the area of its rotor disk (for rotary-wing aircraft) or wing area (for fixed-wing aircraft), it is a critical parameter that characterizes the aerodynamic performance and lift distribution of the aircraft's lifting surfaces. Load is denoted by W_load symbol.

How to evaluate Disk Loading using this online evaluator? To use this online evaluator for Disk Loading, enter Aircraft Weight (W_a) & Diameter of Rotor (d_r) and hit the calculate button.

FAQs on Disk Loading

What is the formula to find Disk Loading?

The formula of Disk Loading is expressed as Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4). Here is an example- 5072.647 = 1000/((pi*0.501^2)/4).

How to calculate Disk Loading?

With Aircraft Weight (W_a) & Diameter of Rotor (d_r) we can find Disk Loading using the formula - Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4). This formula also uses Archimedes' constant .

Can the Disk Loading be negative?

No, the Disk Loading, measured in Force cannot be negative.

Which unit is used to measure Disk Loading?

Disk Loading is usually measured using the Newton[N] for Force. Exanewton[N], Meganewton[N], Kilonewton[N] are the few other units in which Disk Loading can be measured.
