I'd like to perform some calculations using the rocket equation, and I'm trying to find either the Specific Impulse or the Exhaust Velocity for the XR-2 engine. The XR-2 .cfg file shows a Specific Impulse value of 25962. Is that correct? It seems to be very high, as most engines are in the 300-400 range. If that is not an accurate value, I'd appreciate the correct number or the Exhaust Velocity. Also, is there a Specific Impulse or Exhaust Velocity value for the SCRAM engine? The XR-2 flight manual shows a Thrust value but I don't know how to apply that. Thank You!
