Calculate Propeller Thrust







Formula

The formula to calculate the Propeller Thrust is:

\[ F = 0.5 \cdot p \cdot A \cdot (Ve^2 - Vo^2) \]

What is Propeller Thrust?

A propeller thrust is the total amount of force generated by a rotating propeller on an aircraft that causes forward motion.

Example

Let's say you have an air density (p) of 1.225 kg/m³, a cross-sectional area (A) of 0.5 m², an exit velocity (Ve) of 30 m/s, and an aircraft velocity (Vo) of 20 m/s. Using the formula:

\[ F = 0.5 \cdot 1.225 \cdot 0.5 \cdot (30^2 - 20^2) = 153.125 \, \text{N} \]

So, the propeller thrust (F) would be 153.125 N.
