Thrust Coefficient For a Turboshaft Engine Calculator

The thrust coefficient for a turboshaft engine is a dimensionless parameter that characterizes the efficiency of the engine in converting engine power into thrust. Turboshaft engines are commonly used in helicopters and other rotorcraft to provide power for the main rotor.

The thrust coefficient is defined as the ratio of the thrust force produced by the propulsion system to the dynamic pressure of the incoming air. Mathematically, it is expressed as:

where,

where:

• C_T​ is the thrust coefficient,
• $T$ is the thrust force,
• $\rho$ is the air density,
• $V$ is the airspeed,
• $A$ is the reference area.
