Abstract
The present invention relates to a free propeller assembly structure and an aircraft structure has the free propeller assembly. The free propeller assembly structure has at least one free propeller assembly. Each of the at least one free propeller assembly has a circular shaft, a main rotor, a signal transmitting device, and a rotor blade assembly. The main rotor has a shaft hole and multiple blade mounting structures radially disposed. Each blade mounting structure is provided with a positioning recess for mounting a driving motor in each positioning recess. The signal transmitting device includes multiple signal transmitters that are able to transmit interpretable electronic signals or photonic signals. The rotor blade assembly includes at least two rotor blades. One end of each rotor blade is connected with an open end of the positioning recesses of a corresponding one of the blade mounting structures.
