| A design method of a six-module transmitting/receiving antenna is proposed for the research of non-contact signal transmission of high-speed rotating parts in aero engines. The antenna is composed of six arc-shaped patches of different sizes. Its working frequency is 1.3GHz ~ 1.7GHz, and the working bandwidth is ≮40MHz. The transmittin/greceiving antenna model after packaging is established by using electromagnetic simulation software. The variation law of the S-parameters of the antenna with different packaging parameters is analyzed. Based on this, a set of remote measurement rotor/steller engineering application devices is formed. The experimental measurement results show that the working frequency and bandwidth of the antenna meet the design requirements. The low-speed debugging and high-speed rotation verification tests indicate that the formed telemetry device can simultaneously support six transmitter modules. With the conditions of the designed rotational speed ≤20,000 RPM and the ambient temperature ≮80℃, it can stably and effectively transmit signals, and the number of measurement points has doubled, which provides a technical basis for the dynamic stress test of components such as aeroengine compressors and turbines. |
