Helicopter rotor loading and strength flight test is the studying stress loading spectrum of airplane test in actual atmosphere. In the rotor loading test the test devices in the rotor should be strong anti-interference, small size, light weight because rotor high spin speed produces centrifugal force loading with high temperature gas and hot noise. Traditional rotor loading test solution of helicopter cannot meet present requirement due difficult balance between signal transmission reliability and test data real-time acquisition. This article propose a method for multi-channel, wide bandwidth and accurate synchronization rotor loading test
with modular, redundancy and high integration design to modulate, transmit and demodulate the dynamic loading data.
