Thrust-to-Weight Ratio given Vertical Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thrust-to-Weight Ratio = ((Vertical Airspeed/Aircraft Velocity)+((Dynamic Pressure/Wing Loading)*(Minimum Drag Coefficient))+((Lift Induced Drag Constant/Dynamic Pressure)*(Wing Loading)))
TW = ((V_v/V_a)+((P_dynamic/W_S)*(C_Dmin))+((k/P_dynamic)*(W_S)))
This formula uses 7 Variables

Variables Used

Thrust-to-Weight Ratio - Thrust-to-Weight Ratio is a dimensionless ratio of thrust to weight of a rocket, jet engine, or propeller engine.
Vertical Airspeed - (Measured in Meter per Second) - Vertical Airspeed is the rate at which the airplane ascends or descends.
Aircraft Velocity - (Measured in Meter per Second) - Aircraft Velocity is the maximum speed in the takeoff at which the pilot must take the first action.
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.
Wing Loading - (Measured in Pascal) - Wing Loading is the loaded weight of the aircraft divided by the area of the wing.
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.

STEP 1: Convert Input(s) to Base Unit

Vertical Airspeed: 54 Meter per Second --> 54 Meter per Second No Conversion Required
Aircraft Velocity: 206 Meter per Second --> 206 Meter per Second No Conversion Required
Dynamic Pressure: 8 Pascal --> 8 Pascal No Conversion Required
Wing Loading: 5 Pascal --> 5 Pascal No Conversion Required
Minimum Drag Coefficient: 1.3 --> No Conversion Required
Lift Induced Drag Constant: 25 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

TW = ((V_v/V_a)+((P_dynamic/W_S)*(C_Dmin))+((k/P_dynamic)*(W_S))) --> ((54/206)+((8/5)*(1.3))+((25/8)*(5)))

Evaluating ... ...

TW = 17.9671359223301

STEP 3: Convert Result to Output's Unit

17.9671359223301 --> No Conversion Required

FINAL ANSWER

17.9671359223301 ≈ 17.96714 <-- Thrust-to-Weight Ratio
