Abstract

The demand of aeroengine for non-contact telemetry information transmission is very urgent. Based on the analysis of the characteristics of aeroengine telemetry information transmission system, the rotor disk and stator disk suitable for nearfield communication under high centrifugal load are designed in this paper. In order to ensure the stable transmission of telemetry information under large angular displacement between rotor disk and stator disk, a loop-shaped antenna with centrosymmetric characteristics is designed and installed on stator for receiving telemetry information. The designed circular antenna is fabricated and measured. The measurement results show that the circular receiving antenna has good reflection coefficient in the range of 1-4GHz, and its performance can fully meet the needs of aeroengine telemetry information transmission.
