What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12583602B2 to Rolls-Royce Corporation for an "Aircraft override for an energy storage system." The patent describes a power reduction system for aircraft energy storage systems. This system features a controller and an override switch. In its non-override state, the controller manages power reduction based on default parameters. When switched to the override state, the system operates under a relaxed configuration, potentially omitting or easing these parameters.

This patent grant is a notification of intellectual property protection for a specific technological innovation. It does not impose new regulatory obligations on the aviation industry. However, it signifies a development in aircraft power management systems that manufacturers and engineers in the sector should be aware of for competitive and technological landscape awareness. No immediate compliance actions are required based solely on this patent grant.

Abstract

A power reduction system for an energy storage system of an aircraft includes a controller configured to control power reduction of power supplied from the energy storage system to an aircraft engine supply bus; and an override switch configurable in an override state and a non-override state. The override switch is configured to: in the non-override state, permit the controller to control the power reduction according to a default configuration comprising one or more parameters that trigger the power reduction; and in the override state, control the power reduction to be performed according to a relaxed configuration that at least one of relaxes and omits the one or more parameters in the default configuration.
