Latest Patents
One of his latest patents is titled "Bearing preload using external gearbox reaction." This invention outlines a method of operating a gas turbine engine in a multi-engine aircraft. The gas turbine engine features an engine shaft mounted for rotation in a bearing, with a gearbox connected for torque transmission. The method involves axially preloading the bearing using an axially biasing element positioned between the gas turbine engine and the gearbox. This element reacts against the gearbox to exert an axial preload force on both the bearing and the engine shaft.
Another significant patent is "Gear with optimized gear web shape." This invention describes a gear that comprises gear teeth and an annular web that has the gear teeth on its external surface. The web is rotatable about the gear's rotational axis and features a wall with at least a first and a second axial surface. The design of the web includes a first section where the first axial surface inclines away from a radial plane, and a second section where it inclines toward the radial plane.
