Static Thrust Performance Guide

Propulsion Type	Typical Thrust (N)	Efficiency/Notes
Small Drone Propeller	5 – 50	η 0.65 – 0.8
Aircraft Propeller	500 – 5000	η 0.75 – 0.9
Turbojet (Small)	1000 – 10000	High mass flow
Turbofan (Commercial)	100000 – 500000	Optimized for cruise

📌 Note: Static thrust is measured at zero forward velocity (V=0). For propellers: T = C_t × ρ × n² × D⁴, P = C_p × ρ × n³ × D⁵. For jets: T = ṁ × V_exhaust (momentum thrust only, no ram drag). Static thrust is highest at takeoff and decreases with forward speed. Propeller efficiency is typically 0% at static conditions and increases with forward velocity. Use thrust stand testing for accurate measurements. Results are theoretical and actual performance depends on blade design, Reynolds number effects, and installation losses.
