SUMMARY
The discussion clarifies that jet engines exhibit a higher specific impulse compared to rockets primarily due to their larger effective exhaust velocities. While rockets carry their own oxidizers, which affects their specific impulse calculations, jet engines utilize atmospheric oxygen, allowing for a more efficient combustion process. The distinction between actual and effective exhaust velocity is crucial, as it can vary significantly for jet engines, impacting their performance metrics.
