Rocket Engine Isp Analyser
This tool analyses a specific impulse value for a rocket engine.
It can be used for rocket engine analysis, including quantifying fuel efficiency for rocket engines of a given specific impulse value.
The Delta-V Calculator is also useful for specifying exact mass changes at a specific exhaust velocity to calculate delta-v.
