STEP 0: Pre-Calculation Summary
Formula Used
T/W = ((CDmin/WS)+((k)*((n/Pdynamic)^(2))*(WS)))*(Pdynamic)
This formula uses 6 Variables
Variables Used
Thrust-to-weight ratio - Thrust-to-weight ratio is a dimensionless ratio of thrust to weight of a rocket, jet engine, propeller engine.
Minimum Drag Coefficient - Minimum Drag Coefficient is the product of flat plate skin friction coefficient(Cf) and the ratio of wetted surface area to reference area(swet/sref).
Lift Induced Drag Constant - Lift Induced Drag Constant is the reciprocal of the product of the Aspect ratio, Oswald efficiency factor and pi.
Load factor - Load factor is the ratio of the aerodynamic force on the aircraft to the gross weight of the aircraft.
Dynamic Pressure - (Measured in Pascal) - Dynamic Pressure is simply a convenient name for the quantity which represents the decrease in the pressure due to the velocity of the fluid.
STEP 1: Convert Input(s) to Base Unit
Minimum Drag Coefficient: 10 --> No Conversion Required
Wing Loading: 5 Newton per Square Meter --> 5 Pascal (Check conversion here)
Lift Induced Drag Constant: 25 --> No Conversion Required
Load factor: 1.2 --> No Conversion Required
Dynamic Pressure: 10 Pascal --> 10 Pascal No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T/W = ((CDmin/WS)+((k)*((n/Pdynamic)^(2))*(WS)))*(Pdynamic) --> ((10/5)+((25)*((1.2/10)^(2))*(5)))*(10)
Evaluating ... ...
T/W = 38
STEP 3: Convert Result to Output's Unit
38 --> No Conversion Required
38 <-- Thrust-to-weight ratio

## Thrust-to-Weight ratio given the minimum coefficient of drag Formula

T/W = ((CDmin/WS)+((k)*((n/Pdynamic)^(2))*(WS)))*(Pdynamic)

In aerodynamics, wing loading is the total mass of an aircraft or flying animal divided by the area of its wing. The stalling speed of an aircraft in a straight, level flight is partly determined by its wing loading.

## How to Calculate Thrust-to-Weight ratio given the minimum coefficient of drag?

Thrust-to-Weight ratio given the minimum coefficient of drag calculator uses Thrust-to-weight ratio = ((Minimum Drag Coefficient/Wing Loading)+((Lift Induced Drag Constant)*((Load factor/Dynamic Pressure)^(2))*(Wing Loading)))*(Dynamic Pressure) to calculate the Thrust-to-weight ratio, The Thrust-to-Weight ratio given the minimum coefficient of drag is used to maintain a specific banking load at a specific velocity without losing any altitude. Thrust-to-weight ratio is denoted by T/W symbol.

How to calculate Thrust-to-Weight ratio given the minimum coefficient of drag using this online calculator?
