How to Calculate Cruise Weight Fraction for Prop-Driven Aircraft?
Cruise Weight Fraction for Prop-Driven Aircraft calculator uses Cruise Weight Fraction = exp((Range of aircraft*(-1)*Specific Fuel Consumption)/(Maximum Lift to Drag Ratio*Propeller Efficiency)) to calculate the Cruise Weight Fraction, The Cruise Weight Fraction for Prop-Driven Aircraft formula is defined as the ratio of the weight of Aircraft at the End of the Cruise Phase to the weight of Aircraft at the Start of the Cruise phase. The Propeller efficiency plays important role in Cruise Weight Fraction. Cruise Weight Fraction is denoted by FWcruise symbol.
How to calculate Cruise Weight Fraction for Prop-Driven Aircraft using this online calculator? To use this online calculator for Cruise Weight Fraction for Prop-Driven Aircraft, enter Range of aircraft (R), Specific Fuel Consumption (c), Maximum Lift to Drag Ratio (LDmaxratio) & Propeller Efficiency (η) and hit the calculate button. Here is how the Cruise Weight Fraction for Prop-Driven Aircraft calculation can be explained with given input values -> 0.958325 = exp((7126*(-1)*0.000166666666666667)/(5.081*0.93)).
