Abstract: A system includes a venturi duct, a first delta P sensor, a second delta P sensor, and an ECS controller. The venturi duct is configured to receive a first bleed air flow or a second bleed air flow. The first and second delta P sensors are configured to sense a first and second pressure difference between a first point and a second point of the venturi duct. The first and second delta P sensors are configured to sense pressure difference over different pressure ranges. The ECS controller is configured determine a flow rate of an ECS air flow based upon the first pressure and/or second sensed pressure differences.

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: 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.

Abstract: A mixer has an internal bore with an inlet to a chamber, and an outlet at an opposed end/A duct is connected to receive a recirculated air flow. The duct communicates air into the chamber through recirculating air ports such that the recirculating air can mix with the air from the inlet. The mixer housing has a cockpit outlet for delivering air to a second outlet, with the cockpit output being located axially upstream from the recirculating air ports. An isolator is mounted at an outer periphery of the mixer housing, and has flat sides on each of two circumferentially spaced sides. A belly band is bolted to an outer periphery of the mixer housing and to flat sides of the isolator.

Abstract: A mount bracket for use in a cabin air supply system for an aircraft has three legs extending from a cylindrical central bore and at a first axial end of the bracket. There are two legs at an opposed second axial end. A central leg is on the first axial end, and two of the legs are positioned at each of two lateral sides at first and second ends. The legs extend to feet. Strengthening legs connect feet at each of the lateral sides, and to the central leg foot. A thickness of the strengthening legs connected to the central leg is defined as a first dimension. A distance along the first axial end between a laterally outermost portion of the feet at each of the lateral sides is defined as a second dimension. A ratio of the first dimension to the second dimension is between 0.032 and 0.037.
