Non-uniformities in the exit temperature profile of the combustor currently limit the performance of gas turbine engines since the designer must provide margin for hot spots that can damage turbine section compo-nents. A system for controlling fuel spray distributions with potential application for combustor pattern/profile factor control is evaluated. A production fuel injector was modified to include a system of four Coanda jet actuators in the outer swirl cup. In cold-flow tests, the spray distribution was visualized using a laser-based Mie scattering imaging technique. By activating all four Coanda jets simultaneously, it is demonstrated that the spreading rate of the liquid spray can be significantly increased. Activating a single Coanda jet similarly affects the spreading rate on the side of the activated jet while the leaving the remaining spray distribution largely unchanged. This results in a displacement of the fuel spray and, presumably, the heat release zone. Effective control is demonstrated using injected flowrates equivalent to as little as 1% of the total engine air mass flow rate.
