AUTONOMOUS INTEGRATED DEVICE FOR COLLECTION, RECORDING AND MONITORING OF PARAMETERS OF AIRCRAFT GAS TURBINE ENGINE Russian patent published in 2020 - IPC G01M15/14 F02C9/28 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering and is intended for use in onboard systems for collection, recording and monitoring of aircraft parameters using wireless technology for transmitting flight information, mainly for controlling parameters of aircraft gas turbine engine (GTE) and its electronic and electrical equipment. Device comprises GTE parameter registration unit, which is connected to electronic and electrical devices, with ground control panel of engine by communication lines and / or via wireless communication, with PC of ground control laboratory GTE by wireless communication. Parameters registration unit is wirelessly connected to remote server, which transmits flight information to developer, manufacturer and operator of aircraft GTE. In addition, the device contains an electric generator mechanically connected to a high-pressure GTE rotor, wherein the power and switching unit combines power supply from the onboard network and the output voltage of the electric generator, and the auxiliary output of the power supply and switching unit is connected to the parameter recording unit. In addition, the device comprises an electronic motor protection unit, the output of which is connected to the second additional input of the parameter registration unit. Parameters registration unit incorporates module for measuring linear acceleration of engine center of gravity along axes X, Y, Z. Power supply and switching unit combines power supply from onboard circuit +28 V and output voltage of electric generator. Electric generator is a magnetoelectric alternating three-phase alternating current generator and has two power generation channels. In the power supply and switching unit, based on the output voltage of the electric generator, a frequency signal is generated, functionally related to the high-pressure rotor rpm, which is measured in the parameters recording unit. Engine electronics electronic motor output signal is a serial bipolar code according to ARINC-429 with a transmission rate of 100 kbit/s, and polling frequency of output signal of engine electronic unit is not less than 50 Hz. Flight information is recorded for not less than 150 flight hours in annular recording mode. Parameters are transmitted via wireless communication of the Wi-Fi network type via a GSM / GPRS / EDGE communication channel. Remote server used is a server operating over a file transfer protocol such as File Transfer Protocol.

EFFECT: invention allows improving reliability, efficiency and independence of control, reducing time of troubleshooting, increasing level of control over electrical and electronic equipment and efficiency of operation, reducing operational costs for maintenance of aircraft GTE.
