The invention provides an aircraft and an aircraft system. The aircraft comprises a fuselage main body, wings on the two sides of the fuselage main body and an empennage at the tail of the fuselage main body, wherein first rotors are symmetrically arranged on the wings of the two sides, the fuselage main body is further provided with a second rotor, the first rotors are arranged on the sides, neara nose of the fuselage man body, of the wings, the second rotor is arranged at the top of the tail of the fuselage main body, the empennage is arranged at the bottom of the tail of the fuselage mainbody, the empennage is used for supporting the aircraft when the aircraft is in a static state, the first rotors are used for providing ascending power or advancing power when the aircraft is in a flight state, and the second rotor is used for providing ascending power when the aircraft is in the flight state. In this way, the design of the first rotors and the second rotor can prolong the flighttime of the aircraft, and improve portability in actual use of the aircraft.
