SUMMARY
The term C*, also known as 'Characteristic Velocity', is a critical measure in rocketry that quantifies engine performance independent of the exhaust nozzle. It is mathematically defined as c* = (A_t * p_0) / (dm/dt), where A_t represents the throat area, p_0 is the chamber pressure, and dm/dt is the mass flow rate of the propellant. The characteristic velocity is influenced by factors such as gamma, the molecular mass of combustion products, and flame temperature. This distinction clarifies that C* is not merely a name but a significant parameter in rocket propulsion analysis.
