Abstract: A tank has a body defining a chamber therein, the chamber is configured to store a gas at a pressure greater than atmospheric pressure, a first mounting element extending from the body, and a second mounting element extending from the body. The first mounting element and the second mounting element are configured for coupling to a first component of a vehicle and a second component of the vehicle, respectively, and the body is configured to carry a structural load between the first component and the second component when the first mounting element and the second mounting element are coupled thereto. The first component carries a propulsion device and the second component comprises at least one of a wing and a landing element. The tank further includes a stem having an orifice and the stem is configured for delivering the gas to the propulsion device through the orifice.

Abstract: A thermal management system includes a plurality of passages through a leading edge of a component of an aircraft. The thermal management system is configured to circulate coolant from a heat source through the plurality of passages in order to maximize heat transfer from the coolant to the airflow passing over the leading edge.

Abstract: A stack fuel cell array featuring paired fuel-cell systems combined to generate 540 VDC for a rotorcraft. Power from the hydrogen-based fuel cells is provided to the rotorcraft. A rated electrical load of the rotorcraft helps determine how many paired fuel-cell systems are needed during any fuel-cell systems failures. Each of the paired fuel-cell systems is coupled to an electrical load of the rotorcraft. The system detects any fuel cell failures and removes other working fuel cells as needed to balance the electrical system.
