Fan Thrust Performance Guide

Application Typical Thrust (N) Typical Efficiency (η_f)
Small EDF Drone 5 – 20 0.7 – 0.8
RC Aircraft EDF 20 – 100 0.75 – 0.85

📌 Note: Results are based on momentum theory and mass flow rate calculations. Thrust = ṁ × (V_exit – V_inlet) where ṁ = ρ × A × V_exit. Power calculation includes fan efficiency and kinetic energy of airflow. Actual performance depends on duct design, blade geometry, tip clearance, and Reynolds number effects. For EDFs, inlet design and diffuser efficiency significantly impact thrust. Always verify with empirical testing and consider battery discharge characteristics.
