    Abstract: Wireless telemetry system (100) that makes use of integrated wide-bandgap semiconductor technology in a high-temperature environment of a gas turbine engine is disclosed. A wide-bandgap integrated circuitry (WBIC) (98) includes a telemetry transmitter circuitry (106) connected to receive a sensor signal indicative of a condition of the turbine blade. The WBIC may further include power-conditioning circuitry (150) to condition power in a power transfer system (108). A non-stationary antenna (142) may be affixed to the turbine blade. The telemetry transmitter circuitry is connected to the non-stationary antenna to transmit a telemetry signal indicative of the condition of the turbine blade, and a stationary antenna (144) may be affixed to a stationary component to receive the telemetry signal indicative of the condition of the turbine blade. The WBIC is effective for reduction in the footprint and component count compared to telemetry systems involving a discrete circuit implementation.

    Abstract: A method (10) for determining a condition of a second component of an engine is disclosed wherein the engine includes at least a first component and the second component. The method (10) includes determining (12) a concentration value of a chemical species in an effluent obtained from washing at least a portion of the first component of the engine, inputting (14) the concentration value of the chemical species in a condition assessment model to update the condition assessment model, and estimating (16) the condition of the second component based on an output of the updated condition assessment model. The effluent used herein includes a wash fluid and the chemical species. The second component is different from the first component and the condition assessment model is a representative of a condition of the second component of the engine.

    Abstract: A control system for an in-flight engine restart system of a rotorcraft includes an engine control unit that controls and detects status of an engine. The control system also includes a flight control computer that communicates with the engine control unit, an engine operation control system, and a pilot interface including pilot controls. The engine operation control system includes a processor that initiates a health check of the in-flight engine restart system to determine an in-flight engine restart system status. The engine operation control system processes engine mode of operation commands to establish an engine mode of operation, and delivers commands to aspects of the in-flight engine restart system including the engine control unit based on processing of the engine mode of operation commands. The engine operation control system reports the in-flight engine restart system status and results of the engine mode of operation commands to the flight control computer.
