ON-BOARD AIRCRAFT ENGINE MONITORING SYSTEM Russian patent published in 2005 - IPC

FIELD: aircraft instrumentation engineering; on-board monitoring of gas-turbine engines.

SUBSTANCE: proposed system employs information received from aircraft engine parameter sensors and transmitted to multiplexing unit inputs and to on-board computer from output of this unit. Information received from sensors of very important parameters of engine is transmitted directly to command unit input. Present measured magnitudes are compared with specified limits in on-board computer and in command unit on basis of algorithms introduced in their storage. In case of deviation of these magnitudes from specified limits, limiting and dangerous commands are formed and are transmitted to on-board computer and to emergency information system for recording and warning the crew. Actual operating time and residual service life are determined in on-board computer with commands thus obtained taken into account and are transmitted to on-board information system for indication and recording.

EFFECT: possibility of monitoring the aircraft engine in standard, off-standard and augmented power rating conditions.
