The overall goal of the research is to find diagnostic measurements that reliably indicate changes in the dynamics of hypersonic flow paths - scramjet engines in particular. Of primary interest are measurements that serve to indicate that gross changes in flow behavior are about to happen. A priori it is not known if such measurements exist. Local values of state variables (temperature, pressure, velocity, etc.) will necessarily follow changes. The question is whether or not some particular combination of state variables or an additional measureable quantity or quantities can serve as a precursor of impending dynamic changes. Most interesting for hypersonic engine control are changes in isolator margin, inlet mass capture, and performance (thrust, combustion efficiency, etc.).
