Patent number: 11162433Abstract: The present disclosure is directed to a system for controlling an output of a gas generator via an operator manipulated input device. The system includes one or more sensors measuring one or more environmental conditions, a gas generator shaft speed, and a power turbine torque. The system further includes an operator manipulated input device and one or more controllers including one or more processors and one or more memory devices. The one or more memory devices stores instructions that when executed by the one or more processors cause the one or more processors to perform operations.Type: GrantFiled: June 27, 2018Date of Patent: November 2, 2021Assignee: GE AVIO S.R.L.Inventors: Lorenzo Cipolla, Giampaolo Gabbi, Simone Castellani, Federico Dellavalle, Felice Felippone

Publication number: 20200325979Abstract: A spray bar for lubricating gear meshes in an epicyclic transmission has a base having an inlet designed to receive, in use, a flow of pressurized oil. The spray bar has two tube portions, which project from the base along respective axes, define respective channels parallel to each other and permanently communicating with the inlet, and are laterally defined by respective outer surfaces having outlet nozzles for spraying oil from the channels.Type: ApplicationFiled: June 2, 2017Publication date: October 15, 2020Inventors: Michele Gravina, Lorenzo Cipolla, Federico Dellavalle

Patent number: 9662603Abstract: A filtering net, in particular for a rotary separator, has a plurality of cells, which are substantially equal to one another and are defined by the replication of a base cell along two transversal directions of replication; the base cell comprises at least one intermediate filament and a first and a second end filament, arranged on opposite sides of the intermediate filament; the intermediate filament and the end filaments extend along respective longitudinal axes which are parallel; cross-sectioning the base cell with any plane orthogonal to the longitudinal axes of the filaments and joining, on said plane, the trace of each longitudinal axis with the trace of the adjacent longitudinal axis by a respective straight line, the two straight lines are incident at the trace of the longitudinal axis of the intermediate filament and form an incidence angle of between approximately 90° and 160°.Type: GrantFiled: December 30, 2013Date of Patent: May 30, 2017Assignee: GE AVIO S.R.L.Inventors: Stefano Zecchi, Federico Dellavalle, Daniele Coutandin
