Propeller Thrust Calculator
Estimate thrust produced by aircraft or drone propellers
Calculator
Enter air density, velocity, thrust coefficient, and propeller diameter or area to compute thrust.
About the Propeller Thrust Calculator
The Propeller Thrust Calculator helps you estimate the aerodynamic thrust generated by a propeller based on air density, velocity, thrust coefficient, and propeller diameter. This tool is useful for engineers, UAV designers, pilots, and students analyzing drone, aircraft, or RC propeller performance.
What You Can Calculate
- Thrust (T): The aerodynamic pushing force generated by a propeller.
- Disc Area (A): Propeller swept area, derived from diameter.
- Airflow Effects: How changes in velocity influence thrust production.
- Density Effects: How altitude and air density impact propeller performance.
Formulas Used in the Calculator
The calculator uses standard aerodynamic thrust equations for propeller-driven systems:
- Thrust Equation: T = Ct × ρ × A × V²
- Propeller Disc Area: A = π × (D / 2)²
How to Use the Calculator
- Enter the thrust coefficient (Ct) for your propeller.
- Input the air density using the appropriate unit.
- Enter the velocity of air flowing through the propeller.
- Enter the propeller diameter in any supported unit.
- The calculator instantly displays thrust in Newtons, kilograms-force, and pounds-force.
Applications of Propeller Thrust Calculation
Propeller thrust estimation is critical for aircraft design, drone engineering, RC hobby projects, aerodynamics research, and performance testing. Engineers use these calculations to size motors, evaluate propeller efficiency, optimize flight stability, and ensure adequate lift and propulsion for different operating conditions.
