The thrust coefficient (CT) is a dimensionless parameter used in the analysis of propellers and rotors, particularly in aerodynamics and flight mechanics. It describes the ratio of the thrust produced by the propeller or rotor to the dynamic pressure of the incoming air. The thrust coefficient is an essential parameter in understanding the efficiency and performance of these propulsion systems.
CT = Thrust coefficient T = Thrust produced by the propeller or rotor (in Newtons) ρ = Air density (in kg/m^3) n = Rotational speed of the propeller or rotor (in revolutions per second, RPS) d = Diameter of the propeller or rotor (in meter)
