<p>Due to the wide use of gas turbine engines, any performance improvements would  yield significant impacts to many military and civilian programs. While hardware  upgrades require costly replacements to existing equipment, fuel performance  enhancement could provide a near term cost effective solution.  This thesis research focused on the development and qualification of a suitable  test stand system to provide bench testing of nanocatalyst additives for jet fuels on a fullscale  tactical gas turbine engine.  A Williams International F-121 fanjet engine was acquired and set up as the  centerpiece component for the desired test stand. The required auxiliary systems and  sensor equipment were designed and constructed. Initial baseline performance of the test  stand and F-121 engine were demonstrated. These included the ability to determine lean  ignition limits, capability to perform on-the-fly switching of fuel supply during engine  operation, and capability of dynamically performing lean flame-out tests.
