摘要:
A gas turbine engine is provided with a controller configured to detect a spool shaft failure and to initiate an engine shut-down in response to the shaft failure. The controller evaluates the compressor speed probe, the speed probe continuity, P30 pressure and compressor surge to determine whether a shaft failure has occurred.
摘要:
An improved system (11), apparatus and method for estimating thrust from an engine (10), and more specifically, a system (11) for estimating thrust from strain gauge and accelerometer measurements. At least one strain gauge (13) is mounted on an engine (10) mount (44) to measure strain to estimate a constant velocity or steady-state portion of thrust. At least one accelerometer (15) is mounted on the vehicle (50) to measure acceleration to estimate a transient portion of thrust. Steady-state thrust estimation and transient thrust estimation are combined to estimate thrust from the engine (10). An algorithm (23) provides steps for estimating thrust from strain gauge and accelerometer measurements.
摘要:
In one embodiment, a turbine system 10 includes a number of sensors 22, each of the number of sensors disposed in a respective location of the turbine system, and a controller 24 including a memory 26 storing one or more processor-executable routines and a processor 28. The processor configured to access and execute the one or more routines encoded by the memory wherein the one or more routines, when executed cause the processor to receive one or more signals from the number of sensors during any stage of operation of the turbine system, and convert the one or more signals to audio output.
摘要:
A fault detection and diagnosis for a gas turbine engine 12 comprises collecting a sensor signal from an acoustic or vibrational sensor 22 at the gas turbine engine, preprocessing the sensor signal to remove predictable background, and extracting a feature set from the sensor signal using Mel-Frequency Cepstral Coefficients (MFCC) algorithms and/or Code Excited Linear Prediction (CELP) algorithms. Fault and non-fault states are reported based on comparison the feature set and a library of fault and non-fault feature profile corresponding to fault and non-fault states of the gas turbine engine.

Systems and methods for detecting an issue with a starter (104, 300) are provided. One example aspect of the present disclosure is directed to a method for detecting an anomaly with an air turbine starter (304). The method includes receiving, by one or more controllers (106, 306), data indicative of a frequency associated with an integrated air turbine starter (104, 300) from one or more sensors (316) located on a stationary portion of the air turbine starter (304) to monitor a rotating portion of the air turbine starter (304). The method includes determining, by the one or more controllers (106, 306), an anomaly associated with the integrated air turbine starter (104, 300) based at least in part on the data indicative of the frequency. The method includes providing, by the one or more controllers (106, 306), a notification indicative of the anomaly associated with the integrated air turbine starter (104, 300).

Systems and methods for starting an engine (102) on an aircraft are provided. One example aspect of the present disclosure is directed to an integrated starter (104, 300) for starting an engine (102) on an aircraft. The integrated starter (104, 300) includes an air turbine starter (304). The integrated starter (104, 300) includes a starter air valve (302) integrated with the air turbine starter (304). The integrated starter (104, 300) includes a controller (306) configured to control the starter air valve (302). The starter air valve (302) can be movable between a first position and at least a second position to regulate the flow of fluid into the air turbine starter (304). An output torque of the air turbine starter (304) can be dependent at least in part on the flow of fluid into the air turbine starter (304).
