Aircraft with umbrella-shaped fins

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an aircraft with umbrella-shaped blades. Background technique [0002] A chord-wing aircraft refers to an aircraft that uses a non-powered rotor to provide lift and is heavier than air. The propulsion device provides thrust to advance. The propulsion device has two types: propeller and jet. The disadvantages are: 1) when taking off, an initial propulsion force should be given to the rotor through the propulsion device to rotate the rotor to generate lift; 2) the chord-wing aircraft cannot take off vertically; 3) the chord-wing aircraft cannot hover; 4) the structure is complex, And the cost is high. [0003] Therefore, there is still room for improvement in the prior art. Contents of the invention [0004] In view of the above problems, the present invention provides an aircraft with umbrella-shaped blades, which effectively solves the deficiencies of the prior art. [0005...
