Abstract: A gas turbine engine includes a fan section having a plurality of fan blades, the fan section configured to generate an airflow through the gas turbine engine, an airflow passage having a core passage and a bypass passage separate from the core passage, a low-speed shaft coupled to and configured to rotate the plurality of fan blades, and a sensor assembly coupled to the gas turbine engine and configured to detect torsional vibration in the low-speed shaft. The sensor assembly includes a plurality of dynamic pressure sensors in the airflow passage. The plurality of dynamic pressure sensors detect a dynamic pressure of the airflow passage that is indicative of the torsional vibration in the low-speed shaft. A damping system is configured to dampen the torsional vibration in the low-speed shaft based on a correlation of a measured torsional vibration and an experimental torsional vibration.

Abstract: A nebulizer assembly configured for removable attachment to an ultrasonic actuator includes a base plate portion, a porous mesh member, and a cover member. The base plate portion includes an opening extending therethrough, and is substantially rigid such that ultrasonic vibrations from the ultrasonic actuator may be transmitted through the base plate portion to the porous mesh member to vibrate the porous mesh member. The porous mesh member is configured for passage therethrough of a nebulized fluid, and is disposed in the opening of the base plate portion proximate a fluid emission side of the nebulizer assembly. The cover member is disposed on a second side of the nebulizer assembly opposite the fluid emission side. The cover member covers the opening and defines a cavity between the cover member and the porous mesh member. The cavity is configured to retain a fluid to be nebulized.
