Abstract: Environmental control systems and techniques for monitoring heat exchanger fouling are provided herein. In an embodiment, a technique for monitoring heat exchanger fouling includes providing a correlation of heat exchanger fouling to an operating variable. The correlation is programmed into a maintenance system that includes a processor that is adapted to receive data regarding the operating variable. The operating variable is chosen from inlet temperatures of input streams into the heat exchanger and outlet temperatures of output streams out of the heat exchanger, heat exchanger pressure drop, overall heat transfer coefficient value, speed of rotation of an air conditioning machine that includes the heat exchanger, and combinations thereof. Data regarding the operating variable is gathered via a sensor that is adapted to measure the operating variable. The measured operating variable is determined to correspond to excessive heat exchanger fouling in accordance with the correlation using the processor.

Abstract: A system method of estimating health of aircraft brake system friction material includes sensing a temperature of the friction material, and supplying the sensed temperature to a processor-implemented thermal model that is configured to estimate friction material temperatures at one or more locations on the friction material. The estimates of friction material temperatures are supplied to a processor-implemented thermal oxidation model that is configured, based on the estimates of friction material temperatures, to estimate friction material loss due to thermal oxidation. Data representative of runway fluid exposure are supplied to a processor-implemented catalytic oxidation model that is configured, based on the runway fluid exposure, to estimate friction material loss due to catalytic oxidation. The health of the friction material is estimated based on the estimates of friction material loss from the processor-implemented thermal oxidation model and the processor-implemented catalytic oxidation model.

Abstract: A service oriented architecture (SOA) based decision support system for a vehicle is provided. A database is provided for storing a workplan of the vehicle. A webservice provider is in communication with the database for integrating applications using a variety of open standards of an internet protocol backbone. A core is connected between the database and webservice provider. The core is adapted for analyzing fault conditions, creating the workplan to overcome the fault conditions, and generating a response for a webservice request. An enterprise service bus is connected to the webservice provider for providing loose connectivity between webservice enabled functions, a service customer, and the core.

Abstract: A method, system, and computer program product for providing troubleshooting data for reported fault conditions on equipment is provided. An engineering model is configured for the equipment. The engineering model includes at least one failure scenario and an associated symptom. The engineering model is stored in an equipment model database. A meta model representative of at least one relationship between the engineering model and a reported fault condition for the equipment is instantiated. A user input for the reported fault condition is stored in a decision support system (DSS) database. The DSS database forms a wrapper over the equipment model database based on the user input. The meta model is further instantiated using user input data from the DSS database. An optimal troubleshooting procedure for the equipment is determined based on the meta model as instantiated.
