Specific impulse density ratio Calculator

The specific impulse density ratio (ISP) is a parameter used in aerospace engineering to assess the performance of rocket propulsion systems. It’s essentially a measure of how efficiently a rocket engine utilizes its propellant mass to generate thrust.

Where:

  • = specific impulse density ratio
  • = specific impulse (measured in seconds)
  • = propellant density (measured in kilograms per cubic meter)
