Abstract: An environmental control system includes an inlet configured to receive a medium and a compressing device fluidly connected to the inlet. The compressing device includes a compressor operably coupled to a turbine. An outlet of the compressor is fluidly connected to an inlet of the turbine such that the medium is provided to the compressor and the turbine in series. At least one air-liquid heat exchanger is arranged in fluid communication with the outlet of the compressor and the inlet of the turbine. The at least one air-liquid heat exchanger is also connected to a liquid loop containing a liquid. At least one air-liquid regeneration heat exchanger is fluidly connected to the liquid loop at a location upstream from the at least one air-liquid heat exchanger.

Abstract: An environmental control system of a vehicle includes a compressor having a compressor inlet configured to receive a first medium and a compressor outlet. A compressed first medium is provided at the compressor outlet. A conduit is configured to receive a second medium and a heat exchanger is mounted to the compressor. The heat exchanger is fluidly connected to a portion of the compressor and to the conduit.

Abstract: A method of controlling air flow in an environmental control system includes receiving a target total flow value and a combined flow measurement at an outer control loop module. A first air flow reference value is determined based on the target total flow value and the combined flow measurement using the outer control loop module. The first air flow reference value is communicated to an inner control loop module and a flow control valve command determined based at least in part on the first air flow reference value using the inner control loop module. The flow control valve command is communicated to a flow control valve operatively associated with the inner control loop module to control flow through the ECS using the flow control valve. Environmental control systems and computer program products are also described.

Abstract: A bleed air control system and method include first and second flow paths, first and second flow control valves, and a controller. The first flow path is configured to carry a first bleed air flow and includes a heat transfer device configured to transfer heat to or from the first bleed air flow. The second flow path is configured to carry a second bleed air flow. The first and second flow paths merge downstream to provide a combined bleed air flow. The first flow control valve is positioned to control the first bleed air flow, and the second flow control valve is positioned to control the second bleed air flow. The controller is configured to control the first and second flow control valves to control a temperature and flow of the combined bleed air flow.

Abstract: An environmental control system includes a first air flow conduit and a second air flow conduit. A turbine is in fluid communication with the first air flow conduit and a compressor is in fluid communication with the second air flow conduit. The compressor is operatively associated with the turbine. A flow control valve is arranged along the first air flow conduit to control a second air flow in the second air flow conduit according to a first air flow in the first air flow conduit. Aircraft and methods of controlling flow through environmental control systems are also described.

Abstract: An environmental data recorder includes an enclosure, a first acceleration recorder array positioned on a first inner surface of the enclosure corresponding to an x-z plane defined by an x-axis and a z-axis, a second acceleration recorder array positioned on a second inner surface of the enclosure corresponding to an x-y plane defined by the x-axis and a y-axis, and a third acceleration recorder array positioned on a third inner surface of the enclosure corresponding to a y-z plane defined by the y-axis and the z-axis. The x-axis, the y-axis, and the z-axis are orthogonal axes. The first, second, and third acceleration recorder arrays each include a plurality of beams cantilevered at first ends from a base attached to an inner surface of the enclosure and a plurality of known masses associated with the beams. The beams are configured to deform or break when exposed to different g loads.
