The invention relates to the technical field of aircrafts, and particularly relates to an aircraft with umbrella-shaped fins. The aircraft comprises a rack, and is characterized in that a flight device arranged at the top of the rack, a power device arranged in the rack, the flight device comprises a first flight unit and a second flight unit, the first flight unit comprises a sleeve, a bearing and a lower-layer umbrella-shaped fin fixed on the bearing, The bearing is fixed to the sleeve, the sleeve is fixed to the rack, the second flight unit comprises a connecting rod and an upper-layer umbrella-shaped fin, the upper-layer umbrella-shaped fin is fixed to the upper end of the connecting rod, the lower end of the connecting rod penetrates through the sleeve and is connected with the powerdevice, the power device drives the connecting rod to drive the upper-layer umbrella-shaped fin to vertically move up and down in the sleeve, and the upper-layer umbrella-shaped fin and the lower-layer umbrella-shaped fin are respectively provided with a resistance reducing device used for reducing resistance in the ascending process and increasing resistance in the descending process. By the adoption of the structural arrangement, the vertical take-off effect and the hovering effect of the aircraft are achieved, and the aircraft is simple and compact in structure, capable of flying automatically and low in cost.
