    Abstract: Aircraft systems including a fuel tank containing a cryogenic fuel, an engine configured to consume the fuel, and an ECS having a precooler arranged to receive the fuel and air from the engine. The precooler includes a first heat exchanger configured to receive a first state of the fuel and output a second state of the fuel and a second heat exchanger configured to receive the second state fuel and output a third state fuel. The first state has a first density, the second state has a second density, and the third state has a third density, wherein the first density is greater than the second density, and the second density is greater than the third density. The engine air is directed through the second heat exchanger first and then through the first heat exchanger.

    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: A system is disclosed for inerting a fuel tank. The system includes a fuel tank and an air separator including an air inlet, a membrane with a permeability differential between oxygen and nitrogen, an oxygen-depleted air outlet, and an oxygen-enriched air outlet. A catalytic reactor is arranged to receive oxygen-depleted air from the oxygen-depleted air outlet and fuel, to react the fuel with oxygen in the oxygen-depleted air, and to discharge an inert gas from a reactor outlet. An inert gas flow path is arranged to receive inert gas from the reactor outlet, or from the air separation module oxygen-depleted air outlet, or from the reactor outlet and from the air separation module oxygen-depleted air outlet, and to direct inert gas to the fuel tank.

    Abstract: Disclosed is an aircraft including ductwork. The ductwork includes a cabin recirculation vent disposed to draw air from an aircraft cabin. The ductwork includes a riser defining a return conduit disposed to convey air from the cabin recirculation vent. The ductwork includes a thermoelectric heat pump having a first side and a second side, the first side in thermal contact with the return conduit that transfers heat to the second side upon application of an electrical input.

    Abstract: The electronic control has an electric control which incorporates circuitry which will generate heat in use. A cooling channel placed in contact with at least one surface on the electric control. The cooling channel has a portion which receives an enhanced heat transfer surface. At least one electrode pair is mounted on an inlet channel portion upstream of the portion of the channel that receives the enhanced heat transfer surface. A source of current is provided for the electrode. The electrode induces an electric field in the inlet channel, to drive a dielectric fluid across the enhanced heat transfer surfaces.
