What do mean by Propeller?
An aircraft propeller, also called an airscrew, converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type.
The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials.
How to Calculate Propeller Efficiency given Range for Prop-Driven Aircraft?
Propeller Efficiency given Range for Prop-Driven Aircraft calculator uses Propeller Efficiency = (Range of aircraft*Specific Fuel Consumption)/(Maximum Lift to Drag Ratio*ln(Weight at Start of Cruise Phase/Weight at End of Cruise Phase)) to calculate the Propeller Efficiency, The Propeller Efficiency given Range for Prop-Driven Aircraft formula is defined as how efficiently the propeller is converting the power from Engine to Thrust to Propel the aircraft. Propeller Efficiency is denoted by η symbol.
How to calculate Propeller Efficiency given Range for Prop-Driven Aircraft using this online calculator? To use this online calculator for Propeller Efficiency given Range for Prop-Driven Aircraft, enter Range of aircraft (R), Specific Fuel Consumption (c), Maximum Lift to Drag Ratio (LDmaxratio), Weight at Start of Cruise Phase (Wi) & Weight at End of Cruise Phase (Wf) and hit the calculate button. Here is how the Propeller Efficiency given Range for Prop-Driven Aircraft calculation can be explained with given input values -> 11.8357 = (7126*0.000166666666666667)/(5.081*ln(450/350)).
