Power Required for Single Engine Propeller Airplane

In order to compute the power required for Single engine propeller driven airplane we need to have certain parameters.

 

 

The parameters include,

 

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,

  • The Power Required Value is Computed with the help of formula Pr = Tr*V

  • A Table is also generated with the values of Velocity in ft/sec, Thrust Required in lb and the Power Required in ft.lb/sec

  • And finally, the value of the Available Horsepower (hpa) of the Propeller Airplane is computed.
