Thrust Coefficient For a Scramjet Engine Calculator

A scramjet (supersonic combustion ramjet) engine is an air-breathing propulsion system designed to operate at very high speeds, typically in the hypersonic range. The thrust coefficient for a scramjet engine is a dimensionless parameter that characterizes the efficiency of the engine in converting the kinetic energy of the incoming air into thrust.

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.
