This paper describes the application of active, open loop, control in effective damping of
severe combustion instabilities in a high pressure (ie, around 520 psi) gas turbine …

This paper describes the application of active, open loop, control in effective damping of
severe (ie, peak to peak pressure amplitudes of up to 35 psi relative to a mean combustor …

Emphasis on reducing the levels of pollutants created by gas turbine combustors has led to
the development of lean, premixed combustor designs, especially for industrial applications …

In the present work, an atmospheric pressure combustor using a modern aviation gas
turbine fuel nozzle was used to demonstrate active combustion control. The combustor …

Combustion dynamics is a prominent problem in the design and operation of low-emission
gas turbine engines. Even modest changes in fuel composition or operating conditions can …

Described are sub-scale tests that successfully demonstrate active feedback control as a
means of suppressing damaging combustion oscillations in natural-gas-fueled, lean-premix …

One impediment to substantially further the reductions in NOx emissions for aviation gas
turbine engines is thermal-acoustic instabilities, also referred to as combustion dynamics …

This paper describes the application of active, open loop, control resulted in effective
damping of severe (ie, peak to peak pressure amplitudes of up to 60 psi relative to a mean …
