How to Calculate Propeller Efficiency for given Endurance of Propeller-Driven Airplane?
Propeller Efficiency for given Endurance of Propeller-Driven Airplane calculator uses Propeller Efficiency = Endurance of Aircraft/((1/Specific Fuel Consumption)*((Lift Coefficient^1.5)/Drag Coefficient)*(sqrt(2*Freestream density*Reference Area))*(((1/Weight without fuel)^(1/2))-((1/Gross Weight)^(1/2)))) to calculate the Propeller Efficiency, The Propeller Efficiency for given Endurance of Propeller-Driven Airplane can be obtained from the Breguet Endurance formula and is a function of the altitude of aircraft. Propeller Efficiency is denoted by η symbol.
How to calculate Propeller Efficiency for given Endurance of Propeller-Driven Airplane using this online calculator? To use this online calculator for Propeller Efficiency for given Endurance of Propeller-Driven Airplane, enter Endurance of Aircraft (E), Specific Fuel Consumption (c), Lift Coefficient (CL), Drag Coefficient (CD), Freestream density (ρ∞), Reference Area (S), Weight without fuel (W1) & Gross Weight (W0) and hit the calculate button. Here is how the Propeller Efficiency for given Endurance of Propeller-Driven Airplane calculation can be explained with given input values -> 1.37472 = 452.873/((1/0.000166666666666667)*((5^1.5)/2)*(sqrt(2*1.225*5.08))*(((1/3000)^(1/2))-((1/5000)^(1/2)))).
