Effective exhaust velocity (Ve) is a measure used in rocket propulsion to describe the efficiency of a rocket engine. It represents the velocity at which the rocket’s exhaust gases leave the engine relative to the rocket itself, taking into account the effects of pressure and temperature within the engine. It is a crucial parameter in determining the overall performance of a rocket.
where:
- is the effective exhaust velocity,
- is the specific impulse of the rocket engine, and
- is the standard gravitational acceleration (approximately 9.81 m/s²).
