SCOTTY

SCOTTY is an "expert engineer," named after the expert engineer of the future.  Like its fictional human counterpart, SCOTTY is an expert for evaluating the performance of rocket engines.  In this case, the engines SCOTTY evaluates are the Space Shuttle Main Engines (SSME).  Whenever a test firing of the SSME is conducted, a mass of data is recorded from a set of sensors on the engine itself and on the test stand.  This data is then input to SCOTTY which must analyze it to determine if the engine performed properly, and if not, why it did not.  SCOTTY must distinguish between actual data and instrumental anomalies, and then make a determination about the engines performance.  SCOTTY was designed by Abacus and Rocketdyne using a combination of rule-based and modelling techniques.
