The high-speed rotating body telemetry system

1 OverView

We has developed a telemetry transmission and reception system tailored for the requirement of contactless signal transmission in aviation engines. This system wirelessly transmits data collected by sensors in the aviation engine over long distances. The aviation engine signal collector and telemetry transmitter are installed on the rotor and rotate at high speeds with the engine. The telemetry receiving antenna is mounted on the stator and remains stationary. The signal collector sends the data to the telemetry transmitter, which then transmits the signals to the telemetry receiving antenna; subsequently, the signals are sent to a remote telemetry receiver. This receiver demodulates the signals and ultimately retrieves the data information.                              

The system installation schematic is as follows:
