Difference between Endurance and range?
Endurance is the measure of how long any aerial vehicle can stay aloft, it is a measure of time (hours, minutes, seconds). Range is how far an aerial vehicle can get on a load of fuel, it is a measure of distance (miles, kilometers, yards and meters).
How to Calculate Helicopter Flying range?
Helicopter Flying range calculator uses Range of Aircraft = 270*(Weight of Fuel/Aircraft Weight)
*(Lift Coefficient/Drag Coefficient)*(Rotor efficiency*(Coefficient of Power loss)/Specific Fuel Consumption) to calculate the Range of Aircraft, The Helicopter Flying range formula is defined as the distance traversed by the helicopter with constant fuel consumption rate with optimum lift and least drag. Range of Aircraft is denoted by R symbol.
How to calculate Helicopter Flying range using this online calculator? To use this online calculator for Helicopter Flying range, enter Weight of Fuel (G_{T}), Aircraft Weight (W_{a}), Lift Coefficient (C_{L}), Drag Coefficient (C_{D}), Rotor efficiency (η_{r}), Coefficient of Power loss (ξ) & Specific Fuel Consumption (c) and hit the calculate button. Here is how the Helicopter Flying range calculation can be explained with given input values -> 8189.003 = 270*(18000/1000)
*(1.1/30)*(3.33*(2.3)/0.000166666666666667).
