The invention belongs to the technical field of aviation ground tests, and discloses a helicopter ground combined test rotor pitch angle measuring device and method.The device comprises an angular displacement sensor assembly and a steering connecting piece, and in a helicopter rotor system, the angular displacement sensor assembly is connected with the steering connecting piece; a steering rocker arm of a triangular structure is used for steering a control input rod and a rocker arm output rod connected with a booster rocker arm, one triangular end of the steering rocker arm is fixedly connected through a shaft, and the other two triangular ends of the steering rocker arm are connected with the control input rod and the rocker arm output rod through rotating shafts respectively. The angular displacement sensor assembly is fixedly installed on the helicopter, one end of the steering connecting piece is connected with a measuring rod of the angular displacement sensor assembly, and the other end of the steering connecting piece is rotatably installed at the triangular end, connected with the control input rod or the rocker arm output rod, of the steering rocker arm. The rotor pitch angle measuring device does not occupy the peripheral position of the rotor booster, and can measure the pitch angle at a narrow mounting position.
