The invention discloses a helicopter high-low speed transmission switching device which comprises a power input shaft, a power output mechanism, a friction clutch, a low speed switching mechanism, a high speed switching mechanism, a low power transmission mechanism and a high power transmission mechanism; the friction clutch, the low speed switching mechanism, the high speed switching mechanism, the low power transmission mechanism and the high power transmission mechanism are arranged in a shell. One end of the power input shaft penetrates through the shell, and are connected with the friction clutch and the power input end of the low speed switching mechanism, and the low speed switching mechanism is fixed to the high speed switching mechanism; and the power output end of the low speed switching mechanism is connected with the power input end of the low power transmission mechanism. According to the helicopter high-low speed transmission switching device and the speed calculation method thereof, through cooperative control of the friction clutch and an electromagnetic brake, a power transmission path of a helicopter is changed, and the functionality of high-low speed gear shifting of the helicopter is improved; the unpowered output phenomenon occurred in the pure mechanical transmission process is avoided; and thus, the overall performance of the helicopter is optimal in theflight process.
