| 20120111019 | SYSTEM AND METHOD FOR COMBUSTION DYNAMICS CONTROL BY ACOUSTIC CONTROL/CANCELLATION OF FUEL FLOW FLUCTUATION AT FUEL INJECTION LOCATION - A combustion dynamics control system for an aviation based or land based gas turbine engine employs an acoustic driver that is configured to drive pressure perturbations across a premixed fuel injection orifice to substantially zero in response to a control signal such that fuel flow perturbations across the fuel injection orifice are substantially zero. | 05-10-2012 |
| 20120111015 | SELF-OSCILLATING FUEL INJECTION JETS - A combustor structure includes a combustor fuel-air mixing apparatus having a mainstream airflow region. One or more concavities are disposed within the mainstream airflow region of the fuel-air mixing apparatus. At least one fuel injection hole is disposed within an upstream base region of at least one concavity. Passing a stream of air through the main airflow region causes fuel injected into the upstream base region of at least one concavity to passively mix with a naturally oscillating vortex of air within the concavity. | 05-10-2012 |
| 20110266913 | SEGMENTED STATOR ASSEMBLY - A stator assembly includes a segmented stator having stator portions. Each stator portion includes a support structure and dovetails, each coupled to the support structure by adjustable elements. The stator portion also includes stator laminations, where each of the laminations has openings to engage with the dovetails. Connectors are provided to connect the stator portions of the segmented stator together. | 11-03-2011 |
| 20110262705 | MICROSTRUCTURES FOR REDUCING NOISE OF A FLUID DYNAMIC STRUCTURE - A fluid dynamic structure includes a surface and a microstructure mounted on the surface. The microstructure is defined by a plurality of peaks and valleys (i.e., riblets) and includes a transition region in which each peak and valley changes from a first profile to a second profile along a chord length of the structure. The peaks and/or valleys may have a variable dimension along the length of the microstructure. The peaks and valleys can be non-linear along the chord length and have a smooth transition from the first profile to the second profile. The different profiles of the microstructure are optimized to reduce noise generated by turbulent fluid flow across the structure. | 10-27-2011 |
