Abstract

In order to deal with the high-speed real-time data acquisition problem in the dynamic parameter telemetry for aero-engine rotor

helicopter rotor wing and other rotary machines

a novel non-contact parameter telemetry method for rotary machine based on free space optical communication was proposed

and the overall scheme of parameter telemetry system based on this method was given.The key circuits such as laser diode driver

photodetector amplifier

serializer/deseiralizer of the photoelectric data transmission channel were designed.As a result

a free space optical communication transceiver of a theoretical maximum transmission rate of 622Mb/s was designed

and the actual performance was tested.A parameter telemetry experimental prototype was developed.Data transmission rate of the prototype is reach up to 300 Mb/s in rotational state

which satisfy the requirements of dynamic parameter telemetry for aero-engine rotor.
