Propeller Efficiency Calculator







 

 

 

 


How This Is Calculated



$$ \eta = \frac{T v_0}{P} $$ where:

η   =   Propeller Efficiency (Dimensionless)

T   =   Thrust   (N)

v0   =   Freestream Velocity   (m/s)

P   =   Power delivered to the propeller   (W)


Assumptions



  • The system is in steady state.
  • Fluid is incompressible.
  • The flow is at the propeller disk is uniform.
  • The fluid behaves as an ideal gas.
  • There are no propeller interaction effects.
