Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned helicopter. Background technique [0002] An unmanned helicopter generally includes a main fuselage, an empennage, and a tripod. Most of the existing unmanned helicopters adopt the design method of taking the whole machine as a whole. There are also some unmanned helicopters that design and assemble the main fuselage as a whole. The main fuselage includes a frame as the backbone, and various components used to complete the flight function are scattered on the frame. . Therefore, when the existing unmanned helicopters are assembled, debugged, maintained and transported, all need to be carried out for the whole machine. It is not easy to ensure the accuracy during assembly; during maintenance, it is often necessary to overhaul the whole machine due to the failure of individual components, which brings great difficulties to fault diagnosis, and it will...
