Propeller Thrust Calculator

Thrust (T):

Mass flow rate through propeller (ṁ):

Exit velocity of airflow (v_e):

Inflow (freestream) velocity (v₀):

How This Is Calculated

$$ T = \dot{m}v_e - \dot{m} v_0 $$ where:

T = Thrust (N)

ṁ = Mass flow rate through propeller (kg/s)

v_e = Exit velocity of airflow (m/s)

v₀ = Inflow (freestream) velocity (m/s)

Assumptions

The system is in steady flow.
Fluid is incompressible.
Flow is one-dimensional .
The fluid behaves as an ideal gas.
Frictional losses are negligible.
