Thrust Coefficient For a Rolls Royce Gnome Engine Calculator

The Rolls-Royce Gnome is a turboshaft engine, commonly used in helicopters. The thrust coefficient is more commonly associated with propulsion systems like turbojets, turbofans, and rocket engines, where thrust is a primary measure of performance. For turboshaft engines like the Rolls-Royce Gnome, the power coefficient or specific fuel consumption is often used as a measure of efficiency.

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.
