    IPC: B64C19/00

    Abstract: Provided are embodiments for a system for offloading non-thrust loads. The system includes one or more thrust loads, and one or more non-thrust loads, and a controller that is operably coupled to the one or more thrust loads and the one or more non-thrust loads. The controller is configured to control the thrust loads and non-thrust loads, receive input from one or more sources, and identify a phase of flight based at least in part on the received input. The controller is also configured to offload one or more non-thrust loads during the phase of flight, and restore the one or more non-thrust loads. Also provided are embodiments for method for offloading non-thrust loads.

    Abstract: An onboard inert gas system has an electrochemical and a membrane gas separator. The electrochemical separator includes an electrochemical cell including a cathode and anode separated by an electrolyte separator. An electrical power source provides power to the electrical circuit at a voltage that electrolyzes water at the anode and forms water at the cathode, or reduces oxygen at the cathode and forms oxygen at the anode. Oxygen is consumed at the cathode, providing nitrogen-enriched air. Nitrogen-enriched air from the cathode is connected by a flow path to the membrane gas separator, which comprises a membrane having a greater permeability to oxygen or water than to nitrogen. Nitrogen-enriched air from the membrane gas separator that is further enriched in nitrogen, reduced in water content, or both, is connected by a flow path to a fuel tank, a fire suppression system, or both a fuel tank and a fire suppression system.

    Abstract: A tail cone integrated ram air turbine (RAT) includes a rotatable segment of an aircraft tail cone configured to deploy a set of RAT blades. The tail cone integrated RAT also includes a power transfer shaft connected between the rotatable segment and configured to transfer power to from the rotatable segment to an auxiliary power unit (APU). The tail cone integrated RAT further includes a controller connected to the APU and configured to control power output from the APU. When emergency power for an aircraft is needed, the set of RAT blades is deployed from the rotatable segment of an aircraft tail cone. Mechanical power from the rotatable segment is transferred to an APU generator to produce emergency electrical power.
