The invention provides an unmanned fixed-wing aircraft with a large aspect ratio. The unmanned fixed-wing aircraft comprises an aircraft, wherein the aircraft comprises an aircraft body, a wing and a tail; the wing comprises a main wing; accessory wings are respectively arranged at two ends of the main wing; the tail comprises an elevating rudder, a rudder, a horizontal tail and a vertical tail. The unmanned fixed-wing aircraft is simple in structure, and reasonable in design; the strength of the wing and the stiffness of the wing are improved, but the weight of the wing is not significantly increased; the wing is large, so that the flying performance of the aircraft is good, and the flying time of the aircraft is long; the safety of the aircraft is high; the overall stress of the wing is even, so that the phenomenon that the wing is fractured is not liable to occur; the wing is convenient to mount and demount; the aircraft is simple to operate, and is convenient to carry and maintain; the service life of the whole aircraft is prolonged, and the aircraft is wide in applicability.
