Disk Loading Solution

STEP 0: Pre-Calculation Summary

Formula Used

Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4)
W_load = W_a/((pi*d_r^2)/4)
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Load - (Measured in Newton) - Load is the instantaneous load applied perpendicular to the specimen cross section.
Aircraft Weight - (Measured in Newton) - Aircraft weight is the total aircraft weight at any moment during the flight or ground operation.
Diameter of Rotor - (Measured in Meter) - Diameter of rotor is the value of diameter of the rotor of a pump.

STEP 1: Convert Input(s) to Base Unit

Aircraft Weight: 1000 Newton --> 1000 Newton No Conversion Required
Diameter of Rotor: 501 Millimeter --> 0.501 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_load = W_a/((pi*d_r^2)/4) --> 1000/((pi*0.501^2)/4)

Evaluating ... ...

Ultimate Tensile Stress for Plate

Go Ultimate Tensile Strength = (Edge Load per Unit Width*Distance between Rivets)/(Plate Thickness*(Distance between Rivets-Diameter of Rivet))

Shear Failure Load on plate

Go Edge Load per Unit Width = (2*Distance between Rivet and Edge of Plate*Plate Thickness*Maximum Shear Stress)/(Distance between Rivets)

Maximum Blade Efficiency

Go Maximum Blade Efficiency = (2*Blade Lift Force/Blade Drag Force-1)/(2*Blade Lift Force/Blade Drag Force+1)

Allowable Bearing Pressure

Go Bearing Stress = (Edge Load per Unit Width*Distance between Rivets)/(Plate Thickness*Diameter of Rivet)

Shear Load per width

Go Edge Load per Unit Width = (pi*(Diameter^2)*Maximum Shear Stress)/(4*Distance between Rivets)

Joint Efficiency

Go Joint Efficiency for Shell = (Distance between Rivets-Diameter)/(Distance between Rivets)

Disk Loading

Go Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4)

Average Blade Lift Coefficient

Go Blade Lift Coefficient = 6*Thrust Coefficient/Rotor Solidity

Life of Aircraft given number of Flight

Go Number of Flights = (1/Total Damage per Flight)

Disk Loading Formula

Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4)
W_load = W_a/((pi*d_r^2)/4)

Which air mode vehicle has the lowest disc loading?

The use of high disk loading rotors for lift compromises vertical flight capability. Helicopter has the lowest disk loading and thus has the most powerful vertical flight capability.

How to Calculate Disk Loading?

Disk Loading calculator uses Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4) to calculate 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 calculate Disk Loading using this online calculator? To use this online calculator for Disk Loading, enter Aircraft Weight (W_a) & Diameter of Rotor (d_r) and hit the calculate button. Here is how the Disk Loading calculation can be explained with given input values -> 5072.647 = 1000/((pi*0.501^2)/4).

FAQ

What is Disk Loading?

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 and is represented as W_load = W_a/((pi*d_r^2)/4) or Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4). Aircraft weight is the total aircraft weight at any moment during the flight or ground operation & Diameter of rotor is the value of diameter of the rotor of a pump.

How to calculate Disk Loading?

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 is calculated using Load = Aircraft Weight/((pi*Diameter of Rotor^2)/4). To calculate Disk Loading, you need Aircraft Weight (W_a) & Diameter of Rotor (d_r). With our tool, you need to enter the respective value for Aircraft Weight & Diameter of Rotor and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
