Thrust coefficient density ratio Calculator

The thrust coefficient density ratio, often denoted as CT​, is a dimensionless parameter used in aerodynamics to quantify the efficiency of a propulsion system. It’s typically defined as the ratio of the thrust produced by the engine to the product of the dynamic pressure of the air and the area of the engine inlet.

The formula for the thrust coefficient density ratio (CT​) can be expressed as:

Where:

• $T$ is the thrust produced by the engine,
• $\rho$ is the air density,
• $A$ is the area of the engine inlet, and
• $V$ is the velocity of the air entering the engine.
