Abstract: A method and apparatus for estimating a fouling state of a heat exchanger of an aircraft. Training sensor measurements are obtained of a parameter related to operation of the heat exchanger and a wavelet transform is applied to the training sensor measurements to obtain wavelet data. Data reduction is performed on the wavelet data to obtain representative features indicative of the training sensor measurements. A classifier is then trained to assign suitable fouling classes to the representative features. The trained classifier is used on testing sensor measurements from the heat exchanger to assign a fouling class to the testing sensor measurements in order to estimate the fouling state of the heat exchanger.

Abstract: An aircraft inert gas generating system includes a fuel source, an air-fuel mixing unit configured to receive an amount of the fuel and an amount of air an create an air-fuel mixture, and a catalytic oxidation unit downstream of the air-fuel mixing unit and configured to receive and react the air-fuel mixture. The system further includes a condenser downstream of and in flow communication with the catalytic oxidation unit and a cabin exhaust circuit in flow communication with the condenser and configured to provide cabin exhaust air at a first temperature to the condenser. In an alternative embodiment, a pressurized air circuit can provide a stream of cooling air to the condenser. The pressurized air circuit includes a source of pressurized air and a chiller downstream of the source and configured to bring the pressurized air to a first temperature.
