Thrust Required for Propeller Engine Airplane

In order to calculate the thrust required for a single engine propeller driven airplane...

 

 

We need to have the Wing span in feet.

The Wing Area if feet^2/sec.

The Normal Gross Weight of the Airplane in pounds lb.

The fuel capacity of the Airplane in gallons (gal) of aviation gasoline.

The Power-plant / Engine Hourse Power value (hp).

The Specific Fuel Consumption Value in lb/ (hp)(h)

The Parasite Drag Coefficient of the Airplane Cd,0 value.

The Value of the Oswald Efficiency Factor, e.

The Value of the Propeller Efficiency

And the Assumed Velocity in feet /sec.

Performing the Calculation, we get,

  • Value of the Lift Coefficient CL

  • Value of the Aspect Ratio of the Wing

  • The Value of the Total Drag Coefficient of the Airplane, Cd,0

  • The Lift to Drag Ratio of the Airplane (L/D) is computed.

  • And finally, the Thrust Required is Computed with the help of formula, Tr = W/(L/D)

A table is also generated which gives the value of CL, CD, L/D and Tr at different values of Velocity.
