    Abstract: An aircraft system includes a fan, a differential pressure sensor, a temperature sensor, and a system controller. The fan provides airflow for at least one heat exchanger. The differential pressure sensor senses a pressure difference between an inlet of the fan and a diffuser exit of the fan. The temperature sensor senses a temperature at the inlet of the fan. The system controller is configured to receive the sensed pressure difference, the sensed temperature, and a speed of the fan, and determines an operating point of the fan based upon the sensed pressure difference, the speed of the fan, and the sensed temperature. The operating point is indicative of contamination of the at least one heat exchanger.

    Abstract: An environmental control system (ECS) pack is provided including a primary heat exchanger, a secondary heat exchanger, and an air cycle machine. The air cycle machine includes a compressor and a turbine. The compressor is fluidly coupled to an outlet of the primary heat exchanger and to an inlet of the secondary heat exchanger. The outlet of the secondary heat exchanger is fluidly coupled to the turbine. A first conduit connects the outlet of the primary heat exchanger and the inlet of the secondary heat exchanger. The first conduit includes a first valve. A second conduit connects the outlet of the secondary heat exchanger to an air load. The second conduit includes a second valve.

    Abstract: An environmental control system of an aircraft includes a ram air circuit including a ram air shell having at least one heat exchanger positioned therein, a dehumidification system arranged in fluid communication with the ram air circuit, and a compressing device arranged in fluid communication with the ram air circuit and the dehumidification system. The compression device includes a compressor and a first turbine coupled to one another via a shaft. During operation of the first turbine, work is extracted from a first medium within the first turbine to power the compressor. At an outlet of the first turbine, a temperature of the first medium is above freezing and at least a portion of the moisture within the first medium is condensed.

    Abstract: An Environmental Control System (ECS) for an aircraft includes a ram air system having a ram inlet and a ram outlet. The ECS includes a cabin air compressor motor, a diverter valve, and a dedicated outlet. The cabin air compressor motor has a motor inlet passage and a motor outlet passage with the motor inlet passage being coupled to the ram inlet. The diverter valve includes a first diverter inlet, a first diverter outlet, and a second diverter outlet. The first diverter inlet is coupled to the motor outlet passage. The dedicated outlet is connected to the first diverter outlet in a flight mode of operation of the aircraft and the ram outlet is connected to the second diverter outlet in a ground mode of operation of the aircraft.

    Abstract: An aircraft is provided. The aircraft includes a pressurized volume and an air conditioning system. The air conditioning system operates in a first mode when the aircraft is performing high altitude operations and a second mode when the aircraft is performing low altitude operations. The first mode includes when a first medium, a second medium, and a third medium are mixed by the air conditioning system to produce a chamber ready medium. The second mode comprises when only the first medium and the second medium are mixed by the air conditioning system to produce the chamber ready medium. The air conditioning system provides the chamber ready medium to the pressurized volume.
