The fluidic fuel flow modulator developed in this project will enable NASA GRC to evaluate the device in its specially designed characterization test rig for suitability in using it for active combustion instability control. The device will also help in the development of suitable control algorithms by NASA for implementation in actual jet engines. The fuel flow modulator can also be used to mitigate combustion instabilities in liquid fuel rockets as well - thus making the technology available for space launch vehicle design.
The market need for fuel modulators for active control of combustion instability in lean-burn combustors runs in millions both for aircraft engines as well as land-based gas turbines for power generation. In addition, there is a demand for such modulators for active control of reheat buzz in the military airplanes with afterburners. Potential end-customers are: Pratt & Whitney General Electric Siemens Rolls Royce
