Lift-to-Drag Ratio for given Endurance of Jet Airplane Solution

STEP 0: Pre-Calculation Summary
Formula Used
Lift-to-Drag Ratio = Thrust-Specific Fuel Consumption*Endurance of Aircraft/(ln(Gross Weight/Weight without Fuel))
LD = ct*E/(ln(W0/W1))
This formula uses 1 Functions, 5 Variables
Functions Used
ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)
Variables Used
Lift-to-Drag Ratio - The Lift-to-Drag Ratio is the amount of lift generated by a wing or vehicle, divided by the aerodynamic drag it creates by moving through the air.
Thrust-Specific Fuel Consumption - (Measured in Kilogram per Second per Newton) - Thrust-Specific Fuel Consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output.
Endurance of Aircraft - (Measured in Second) - Endurance of Aircraft is the maximum length of time that an aircraft can spend in cruising flight.
Gross Weight - (Measured in Kilogram) - The Gross Weight of the airplane is the weight with full fuel and payload.
Weight without Fuel - (Measured in Kilogram) - Weight without Fuel is the total weight of the airplane without fuel.
STEP 1: Convert Input(s) to Base Unit
Thrust-Specific Fuel Consumption: 10.17 Kilogram per Hour per Newton --> 0.002825 Kilogram per Second per Newton (Check conversion ​here)
Endurance of Aircraft: 452.0581 Second --> 452.0581 Second No Conversion Required
Gross Weight: 5000 Kilogram --> 5000 Kilogram No Conversion Required
Weight without Fuel: 3000 Kilogram --> 3000 Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
LD = ct*E/(ln(W0/W1)) --> 0.002825*452.0581/(ln(5000/3000))
Evaluating ... ...
LD = 2.50000014307235
STEP 3: Convert Result to Output's Unit
2.50000014307235 --> No Conversion Required
FINAL ANSWER
2.50000014307235 2.5 <-- Lift-to-Drag Ratio
