1. An unmanned aerial system, comprising:
an airframe; and
a fixed-wing assembly and a rotor assembly, both replaceably connectable to the airframe,
wherein the fixed-wing assembly is configured to be connected to the airframe to form a vertical take-off and landing fixed-wing unmanned aerial vehicle and wherein the rotor assembly is configured to be connected to the airframe to form a multi-rotor unmanned aerial vehicle;
wherein the unmanned aerial vehicle further comprises a tail wing assembly detachably connected to the airframe; and
both a lower vertical stabilizer and the fixed-wing assembly are connected to the airframe to form the vertical take-off and landing fixed-wing unmanned aerial vehicle; the tail wing assembly is rotatable relative to the airframe around a pitch axis direction when the tail wing assembly is connected to the airframe;
the tail wing assembly is rotatable relative to the airframe around the pitch axis direction when the tail wing assembly is connected to the airframe
two second mounting portions are disposed on the airframe;
the two second mounting portions are respectively disposed on two sides of the airframe in the pitch axis direction of the airframe, each of the second mounting portions comprises a second mounting surface, and a shaft hole and an arc-shaped guide hole are jointly formed on the two second mounting portions, both the shaft hole and the arc-shaped guide hole passing through second mounting surfaces of the two second mounting portions, the shaft hole being provided in the pitch axis direction and the arc-shaped guide hole being provided around the shaft hole;
the tail wing assembly comprises a rotary shaft, a transmission shaft and two tail wing components; and
the rotary shaft is configured to be inserted into the shaft hole and has two ends both exposed outside the shaft hole; the transmission shaft is configured to be inserted into the arc-shaped guide hole has two ends both exposed outside the arc-shaped guide hole; each tail wing component comprises a second assembling surface for being in contact with a second mounting surface of a corresponding second mounting portion.
