    摘要: A distributed controller of an aircraft includes a first communication device, a second communication device, and at least one processor. The first communication device is configured to transmit heater status data and receive heater command data via radio waves or power-line communication. The second communication device is configured to transmit at least one heater control signal and to receive heater sensor data. The at least one processor is configured to provide heater control based upon the heater command data and the heater sensor data and to provide heater status information based upon the received heater sensor data.

    摘要: An aircraft environmental control system (4) for controlling a temperature of a fluid, the control system (4) comprising: a temperature sensor (30) configured to measure a temperature of the fluid and to generate a signal, the first signal being indicative of the measured temperature; a control signal generator (52) configured to, dependent upon the first signal, generate a control signal for controlling the temperature of the fluid; and one or more processors (64) configured to, responsive to determining that the measured temperature oscillates about a central value, decrease a gain of the control signal generator (52).

    摘要: A computer-implemented method, environmental control system (ECS) for an aircraft, and system are provided. Air temperatures at the inlet and outlet of a ram air duct for an ECS are measured. Also, air temperatures at outlets from one or more heat exchangers arranged in the ram air duct are measured. The temperatures are typically measured when the aircraft is on the ground and when aircraft engines supplying air to the ECS are operating at idle. Shortly thereafter, the heat exchangers are manually inspected to determine a level of actual fouling (e.g., dirt, dust, or other debris accumulated on heat exchanger surfaces). A supervised machine learning or other statistical analysis is performed on the measured temperatures and associated actual fouling levels to develop a model that predicts an amount of heat exchanger fouling, based on the temperature measurements. An alert can be output if the predicted fouling exceeds a fouling threshold.
